Zhai, S., 2020. Spatio-temporal differences of the contributions of marine industrial structure changes to marine economic growth. In: Yang, Y.; Mi, C.; Zhao, L., and Lam, S. (eds.), Global Topics and New Trends in Coastal Research: Port, Coastal and Ocean Engineering. Journal of Coastal Research, Special Issue No. 103, pp. 1–5. Coconut Creek (Florida), ISSN 0749-0208.

The continuous expansion of the differences in marine economy affects the realization of China's maritime power strategic goals. Therefore, it is necessary to recognize the level of development of the marine economy, analyze the actual differences in coastal areas and find out the constraints. Sustainable development has important value. This paper mainly studies the spatial-temporal differences in the contribution of marine industry structural changes to marine economic growth. The cumulative contribution rate of 6 principal components extracted in this paper reaches 93.346%. The 6 principal components can explain the comprehensive development level of the marine economy in coastal provinces and cities. It shows that its comprehensive development level is below the average development level. It can be seen from the calculation results that the internal structure of the industry is constrained by the level of science and technology, scientific and technological breakthroughs are difficult, and the evolution of the industrial structure is slow, so its contribution to the growth of the marine economy is relatively low. Therefore, in the process of optimizing the structure of the marine industry, more attention must be paid to improving the development mode and quality of the marine industry, giving play to the role of science and technology, improving the quality of the supply of the marine industry, transforming and upgrading the traditional marine industry, mastering core technologies for the development of the marine industry, and fostering the Market competitiveness of the industry.

(eds.), Global Topics and New Trends in Coastal Research: Port, Coastal and Ocean Engineering. Journal of Coastal Research, Special Issue No. 103, pp. 11–14. Coconut Creek (Florida), ISSN 0749-0208.

Taking s port as an example, this paper studies the relationship between s port economy and hinterland economy. VAR model is introduced for quantitative analysis, and the relevant indicators reflecting port economy and hinterland economic variables are selected. Stability test and VAR vector regression are used for regression analysis. Variance decomposition and mapping are used to analyze the interactive development relationship between port economy and hinterland economy. The empirical results show that the s-port economy plays a weak role in promoting the economic development of the hinterland, while the s-port hinterland economy, especially the total import and export variables, plays the strongest role in promoting the economic growth of the port. Some suggestions are put forward to promote the stable, healthy and high-quality growth of port economy under the anti-dumping policy.

(eds.), Global Topics and New Trends in Coastal Research: Port, Coastal and Ocean Engineering. Journal of Coastal Research, Special Issue No. 103, pp. 47–51. Coconut Creek (Florida), ISSN 0749-0208.

This paper studies the interactive mechanism between the characteristic town of Zhejiang Province and the industrial upgrading. We examined how aspects of characteristic town influenced industrial upgrading, such as industry merit-based and synergistic mechanism, mechanism of technological innovation and mechanism of brand effect--high consumption. In a longitudinal, multiple-informant study of characteristic towns in Zhejiang Province, we found that industry merit-based and synergistic mechanism, mechanism of technological innovation and mechanism of brand effect--high consumption and their interrelationships selectively influenced planning and development of a characteristic town. As anticipated, industry merit-based and synergistic mechanism and mechanism of technological innovation positively influenced characteristic town, they can promote industrial transformation and upgrading. Counter to our expectations, however, mechanism of brand effect—high consumption by itself was negatively associated with characteristic town. Interestingly, the three mechanisms played a significant role in characteristic town, as it positively influenced industrial transformation and upgrading.

(eds.), Global Topics and New Trends in Coastal Research: Port, Coastal and Ocean Engineering. Journal of Coastal Research, Special Issue No. 103, pp. 70–73. Coconut Creek (Florida), ISSN 0749-0208.

In context of building “Belt and Road”, e-commerce has developed rapidly. Therefore, how to evaluate and measure its influential factors is worth exploring. This article uses an extended trade gravity model to empirically explain the influencing factors of CBEC volume scale between “Belt and Road” countries and China. This study results show that similar to traditional trade, per capita income, consumer groups, and additional factors affect the scale of CBEC signifigantly, especially geographical distance has a significant obstacle to the size of CBEC transactions. Additionally, the above estimated results of the newly added explanatory variables such as logistics performance index and Internet penetration are basically in line with expectations. In particular, the logistics performance index has the most obviously positive effect on CBEC exporting and CBEC importing. China would strengthen cooperating with Belt and Road countries in the aspect of e-commerce, create a good business environment, encourage infrastructure construction so as to develop the potential of CBEC markets.

Li, Y., 2020. Mathematical economics analysis of macro debt and economic growth in coastal areas. In: Yang, Y.; Mi, C.; Zhao, L., and Lam, S. (eds.), Global Topics and New Trends in Coastal Research: Port, Coastal and Ocean Engineering. Journal of Coastal Research, Special Issue No. 103, pp. 90–94. Coconut Creek (Florida), ISSN 0749-0208.

Path choice of economic development for a country is a very important question. After China adopt the policy of Reform and Opening up, the economic development model depending on high investment and high debt has been established gradually, which causes the success of China economic development. Especially, the economic development of the coastal regions has provided a powerful impetus for the progress of the entire country. However, this pattern overly depending on the investment and debt accumulation brings hidden trouble to China's future development of high quality. In this paper, the economic relationship between the debt accumulation and economic growth will be analysed in detail by the mathematical analysis tools and optimization theory. At the same time, this article also proposes that coastal economic areas should take the lead in developing technology-intensive industries and vigorously develop the marine economy to achieve economic transformation.

Tao, C. and Wang, Y., 2020. The spatial spillover effect of China's government health expenses on the regional economy: Empirical analysis based on the spatial panel model. In: Yang, Y.; Mi, C.; Zhao, L., and Lam, S. (eds.), Global Topics and New Trends in Coastal Research: Port, Coastal and Ocean Engineering. Journal of Coastal Research, Special Issue No. 103, pp. 95–100. Coconut Creek (Florida), ISSN 0749-0208.

Government health expenses not only affects the local economic development through direct and indirect mechanisms but also affects the economic development of neighboring regions through the spatial spillover effect. This paper investigates the spatial correlation and spatial agglomeration between government health expenses and regional gross domestic product in China from 2005 to 2015. On this basis, it further analyzes the impact of government health expenses on regional gross domestic product by constructing a spatial Durbin model. The empirical results show that China's government health expenses has a significant positive spatial spillover effect on regional economic development, and the indirect effect caused by the spatial spillover is equivalent to the direct effect. Therefore, if spatial factors are not taken into account, the impact effect will be overestimated to a large extent.

Qian, A.; Zhu, X., and Wang, F., 2020. Economic loss dynamics of rare earth industry along the Yellow River: Taking renewable energy accounting as an observation indicator. In: Yang, Y.; Mi, C.; Zhao, L., and Lam, S. (eds.), Global Topics and New Trends in Coastal Research: Port, Coastal and Ocean Engineering. Journal of Coastal Research, Special Issue No. 103, pp. 101–106. Coconut Creek (Florida), ISSN 0749-0208.

The environmental pollution and ecological destruction caused by the exploitation of raw materials in the renewable energy industry is a neglected topic at present. Poor environmental management is one of the important reasons for the ecological damage of renewable energy projects. Rare earth resources are the main raw materials for renewable energy, and their production and mining mainly take place in China. According to Chinese government, the pollution caused by rare earth was most obvious between 1992 and 2010 and mainly happened in Baotou, which contributed 80% of global rare earth production. Therefore, this paper will combine the development of renewable energy before 2009 to demonstrate the pollution of China's rare earth mining areas. Based on the Input-Output Table developed by the European Union, by using multi-country input-output model to study the renewable energy consumption. It is found that, in rapid development period of renewable energy, the smaller the gap between global supply and demand, the greater the degree of exploitation in production areas, and the greater the ecological degradation. Based on 2019 IRNEA's forecast, our paper holds that the global renewable consumption can be used as a more intuitive indicator for the government to evaluate the economic loss level caused by the rare earth industry.

Wang, X.; Ren, Y.; Zhang, L., and Ma, Y., 2020. The influence of technological innovation ability of universities on regional economic growth: Take coastal provinces and cities for example. In: Yang, Y.; Mi, C.; Zhao, L., and Lam, S. (eds.), Global Topics and New Trends in Coastal Research: Port, Coastal and Ocean Engineering. Journal of Coastal Research, Special Issue No. 103, pp. 112–116. Coconut Creek (Florida), ISSN 0749-0208.

University is a significant part of the national innovation system. Technological innovation of universities has become an important driving force of economic growth and achieving high-quality economic development. This paper uses a variety of spatial econometric analysis techniques to investigate the inter-regional flow of the elements of university scientific and technological innovation capability and the effects of university technological innovation ability on economic growth and further studies the direct and indirect effects of university technological innovation capability by using panel data of coastal provinces and cities in China from 2005 to 2017. This research finds that the scientific and technological innovation ability of universities has obvious spatial spillover effect and it has a significant positive impact on regional economic growth. And the spatial spillover effect is greater than the direct effect, that is to say, the elasticity coefficient of the technological innovation ability of colleges and universities in the surrounding areas to the regional economic growth is greater than that of colleges and universities in the region. In addition, the investment of fixed assets, the process of urbanization and the scale of government only have the direct effect on the regional economic growth, and there is no spatial spillover effect. The scale of government and the opening-up have the direct effect and spillover effect. The conclusions for this study provide a useful reference for the government and universities to strengthen the technological innovation ability of universities so as to promote regional economic growth.

(eds.), Global Topics and New Trends in Coastal Research: Port, Coastal and Ocean Engineering. Journal of Coastal Research, Special Issue No. 103, pp. 117–119. Coconut Creek (Florida), ISSN 0749-0208.

At present, the development of hydropower market in most countries and regions are still at the initial stage, and existing laws and regulations are not adequate enough. The hydropower market is still in the dynamic evolution and development. This paper carried out the evolutionary game analysis of the hydropower market and compared the payoff matrix of power producers when there is a serious power supply shortage. It is found that PAB (pay as bid) settlement is conducive to the stability of power price. When power supply exceeds demand, the on-grid price under MCP (market clearing price) will be lower than that under PAB, which stabilizes and balances development of power market.

Kong, Q. and He, J., 2020. Controlling methods of driving factors in the economic development of coastal areas. In: Yang, Y.; Mi, C.; Zhao, L., and Lam, S. (eds.), Global Topics and New Trends in Coastal Research: Port, Coastal and Ocean Engineering. Journal of Coastal Research, Special Issue No. 103, pp. 129–133. Coconut Creek (Florida), ISSN 0749-0208.

The traditional method for controlling economic development factors has a large deviation when measuring the growth rate of comprehensive factors of economic growth. Therefore, a method for controlling the driving factors of economic development and evolution in coastal areas is proposed. This method extracts the characteristics of the economic development and evolution of the coastal areas, calculates the overall difference in the quality of development, and finds that there are significant high-value clusters in the spatial quality of economic development in the coastal areas. Establish an economic driving factor indicator system, analyze the main driving factors, and study the dynamic changes in the production and consumption levels in coastal areas. Establish a control model to regulate and control the economic systems in coastal areas. This completes the control method of the driving factors for the economic development and evolution of the coastal areas. The experimental results show that the comprehensive factor growth rate calculated by this method is closer to the real value than the traditional method, which verifies the effectiveness of the design method.

Therefore, it is necessary to build a unified legal system of international trade and financial supervision cooperation at sea to protect the international financial supervision order. Due to the particularity of financial regulatory activities, the international community has not yet formed a unified legal system of international financial regulatory cooperation, and the urgent requirements of the globalization of financial activities for international financial regulatory cooperation make improving the legal framework of international financial regulatory cooperation become one of the important issues discussed by the international community today. The existing forms of international cooperation lay the foundation for the establishment of a unified legal mechanism for international cooperation in financial supervision. On the basis of the existing system, the current situation of the existing legal system in some countries and regions is analyzed. According to the analysis results, a new legal system for regulatory cooperation is constructed with the main research content of legal cooperation subjects, forms and contents. Through the form of empirical analysis, to verify the effectiveness of the designed legal system, the analysis results show that the system can effectively reduce the probability of financial events, which is conducive to the protection of financial order.

(eds.), Global Topics and New Trends in Coastal Research: Port, Coastal and Ocean Engineering. Journal of Coastal Research, Special Issue No. 103, pp. 222–225. Coconut Creek (Florida), ISSN 0749-0208.

The aim of this study was to assess actual fatal occupational injury rates and to analyze their fluctuations and trends in China. Based on data of work-related injury insurance, we proposed a method to calculate fatal occupational injuries per 100,000 workers (FOIPW) in China. Emphasis was placed on regional differences based on the Thiel index model. The results showed that China's FOIPW is decreasing, but remains higher than that of developed countries. The regional differences in FOIPW across China were also found to be narrowing. Specifically, Western China has the highest rates of FOIPW whilst the eastern coastal area has the lowest rates. Compared to central and Western regions, the internal disparity in fatal injury rates in the eastern coastal area are more obvious. This study will promote a clearer understanding and effective control of fatal occupational injuries in eastern coastal area and other areas of China, and ensure the balanced development of economy and society in the future.

(eds.), Global Topics and New Trends in Coastal Research: Port, Coastal and Ocean Engineering. Journal of Coastal Research, Special Issue No. 103, pp. 231–235. Coconut Creek (Florida), ISSN 0749-0208.

Overseas mergers and acquisitions have gradually become an important form for Chinese companies to make overseas investments. However, due to the uncertainty of the international environment and differences between countries, overseas mergers and acquisitions by Chinese companies have shown difficulties in reaching transactions. The reasons are worth exploring. This article mainly studies the overseas mergers and acquisitions of maritime enterprises under the background of marine economic adjustment and optimization. This article analyzes the process of identifying and controlling the risks of merger and acquisition technology integration in enterprises, and studies the technological integration mechanism of overseas mergers and acquisitions of maritime enterprises under the background of marine economic adjustment and optimization, and provides a reference for manufacturing enterprises implementing overseas mergers and acquisitions in technology integration. This paper studies that after the acquisition of overseas companies in 2015, it achieved a 0.67% increase, but its asset-liability ratio decreased by 0.04%. It reflects that this overseas merger and acquisition has not affected the company's debt scale on the basis of expanding the asset scale. From the analysis of risk aversion, the long-term performance of this overseas merger and acquisition is effective.

Coconut Creek (Florida), ISSN 0749-0208.

Given increasing studies on the impact of financial development on income distribution at home and abroad, this paper conducts a multi-level, multi-angle theoretical and empirical study on the impact of China's financial development on income distribution based on the historical background of China's financial system and financial market development. In recent years, China's Internet finance has experienced explosive growth, and its unprecedented heated discussion has reflected, to some extent, the expectations of the practical circles and even the public for its financial function deepening. In the empirical analysis, model regression analysis method is employed to study the income distribution effect of Internet finance development in China. The results show that the urban residents' education rate of return is much lower than the average rate of return. For the most significant proportion of groups, those who have signed the labor contract have higher income than those not. Finally, some policy suggestions are proposed on standardizing income distribution from the aspects of education, technical training and law.

(eds.), Global Topics and New Trends in Coastal Research: Port, Coastal and Ocean Engineering. Journal of Coastal Research, Special Issue No. 103, pp. 284–287. Coconut Creek (Florida), ISSN 0749-0208.

The bearing capacity of the structure foundation in the ocean engineering is required to be very high due to the long-term bearing complex loads such as wind load, wave load, earthquake and current tide. The inclined steel-pipe pile foundation is widely used in the ocean engineering because its bearing capacity is better than that of the straight pile. Compared with the common steel-pipe piles, the construction and testing of inclined steel-pipe piles are more difficult, with few researches at home and abroad. In this paper, an engineering example is introduced, in which the inclined steel-pipe piles are used as the foundation, and the pile driving barge is used to hammer them to complete the foundation construction of the footbridge. In addition, in order to determine their bearing capacity, the O-cell method is used to carry out field tests on two inclined steel-pipe piles for the first time in China. Finally, the test shows that the bearing capacity of one of the inclined steel-pipe piles is not enough. Then, the pile driving barge is used to hammer it. After the second O-cell test, it is found that the bearing capacity meets the design requirements.

(eds.), Global Topics and New Trends in Coastal Research: Port, Coastal and Ocean Engineering. Journal of Coastal Research, Special Issue No. 103, pp. 288–292. Coconut Creek (Florida), ISSN 0749-0208.

The dissipation term is introduced into the free surface boundary conditions, and a newly developed ideal fluid potential flow model is used to numerically simulate a group of vertical cylinders. The wavenumber associated with the new boundary condition at the free surface defined by the dispersion relation becomes complex and wave decay factor is represented by the imaginary part of the wavenumber. To describe the velocity potential, the analytical method based on the expansion of eigen functions is used in the fluid domain. The Bessel functions of the complex variables are then involved in the series expression of the velocity potential. The unknown coefficients are determined by satisfying the boundary condition on cylinder surface in the Galerkin form. The eigen function expansion gives an accurate expression of velocity potentials. The effect of dissipation at the free surface can then be analyzed in a reliable and practical way. By comparison with existing model measurements, it is shown that the solution with dissipation is much more realistic, in particular, the first-order wave loading and second-order drift forces which are more sensitive to the dissipation for a wave frequency in the vicinity of trapping resonance frequency.

Then it is indicated that cover 57% of the whole length of riser is a cost-effective arrangement suggestion. This arrangement could reduce the transverse Vortex-induced vibration (VIV) response obviously. The maximum ratios of RMS Amplitude divided by External Diameter (A/D) and stress was reduced to 20% compared to the bare one.

Gas outbursts occur frequently in the process of uncovering coal in crosscut, so it is of great significance to study the outburst conditions of coal and gas in the process of tunneling. By establishing the model of these gas outbursts, we can obtain the function of the thickness of stone gate, gas pressure and gas outburst. With or without high pressure gas, the impact of high pressure gas during gas bursts is analyzed through the numerical simulation method. Based on the velocity, displacement, maximum principal stress and time curve of coal and rock interface in the center of roadway under two kinds of working conditions, the main conditions of gas bursts have been successfully verified. According to the results, in coal and gas outbursts, necessary conditions include the plastic zone penetration caused by high pressure gas storage and excavation disturbance, while sufficient conditions include the mutation of velocity field, displacement field and stress field in plastic zones.

In: Yang, Y.; Mi, C.; Zhao, L., and Lam, S. (eds.), Global Topics and New Trends in Coastal Research: Port, Coastal and Ocean Engineering. Journal of Coastal Research, Special Issue No. 103, pp. 339–345. Coconut Creek (Florida), ISSN 0749-0208.

Abnormal fluid pressure commonly exists in oil and gas-bearing basins. Abnormally high pressure often coexists with undercompaction, whereas abnormally low pressure is often related to rock porosity rebound. The Voigt-Reuss-Hill (V-R-H) equation, which is the arithmetic mean of the Voigt upper bound and the Reuss lower bound, is often used to calculate the bulk and shear moduli of mixed minerals. In this study, it is considered that the moduli of mixed minerals are closer to the Reuss lower bound in abnormal high-pressure reservoirs and the Voigt upper bound in abnormal low-pressure reservoirs. Hence, a new equation is proposed for calculating the moduli of mixed minerals. Then, the Digby model and the Gassmann equation are used to predict shear-wave (S-wave) velocities, which are subsequently compared with the measured results. The results show that the errors in S-wave velocities predicted by the proposed method are lower than 6%.

This paper designs the finite-time stabilization control for the electric control diesel engine in model deviation and load perturbation. First, due to the use of nonlinear piecewise function, the conventional ADRC have too many control parameters, which led to theory analysis and engineering application is difficult. Because of the inverse hyperbolic sine function is smooth curve, we use it to establish ADRC, which will reduce the adjusting parameters, decrease the difficulty of the theoretical analysis, and it is convenient to be used in engineering. Second, the feedback control law we design the finite time convergence properties ADRC for better control effect. From the simulation, we know that the new algorithm has better control effect.

The large-scale steel pipe pile filled with concrete is usually adopted as the foundation of wind farm in China which subjected to the loads including wind turbine weight, wind, wave, fluent and so on. There is high requirement of bearing capacity and deformation of foundation for the wind turbines and it is difficult to measure the displacement accurately using traditional displacement measurement system because of environmental load variation. This paper presents a new method of displacement measurement that the linear displacement underground can be transformed into angular displacement on the ground, and angular displacement can be transformed into some pulse signal through a snap-sheet device and grating sensor. According to the number of pulse signal, the grating groove density and diameter of the wheel, the corresponding displacement can be calculated, and operating procedures is developed for measurement based on LabVIEW software. This new measurement system has the advantages of easy installation, accuracy measurement, simple operation and high reliability and it has high applicability for offshore pile tests.

Coconut Creek (Florida), ISSN 0749-0208.

The Steer-By-Wire (SBW) system is free from the constraints of mechanical structure. Whether the system can work normally depends on the correctness of the control strategy. Therefore, this paper will study the control strategy of active steering by wire, which includes the design of ideal variable angle ratio control and active front wheel steering controller. Feed-forward control of ideal variable angle transmission ratio was determined based on constant yaw angular velocity gain. The sliding mode variable structure control theory is adopted. Based on the yaw rate deviation, the integral sliding surface is constructed, and the control strategy of equivalent and switching control is designed and active front wheel steering controller is completed. Through feedback control, the active control of the vehicle's front wheel angle is achieved, which improves the stability of the vehicle. Finally, through the typical test conditions, the designed control strategy was simulated and verified, and compared with the simulation results of uncontrolled vehicles. The results showed that the sliding mode controller of active SBW front wheel designed by yaw angular velocity feedback under the ideal variable transmission ratio can run stably under any working conditions and achieve good track following ability.

In order to study the hydrodynamic performance of multiple vertical tidal current turbines, an analysis model based on free vortex model is proposed. By comparing with experiment data, the present model can obtain reasonable results. Then the hydrodynamic performance of twin-turbine and quad-turbine systems are studied using the present model. For twin-turbine system, five sets of turbines spacing and three sets of rotation direction are researched. And five sets of rotation direction are researched for quad-turbine system with one turbine spacing. By comparison, it is shown that positive effect on the relative power coefficient can be found at high TSR when turbines are side-by-side arrangement. At the same time, in most cases, it can obtain a higher relative power coefficient when turbines are rotating inward and have a smaller spacing. Due to the low computational time, the present method can be used in preliminary study on array arrangement of vertical axis tidal current turbine.

Aiming at the noise and vibration problems in the gear transmission process, taking the small sun wheel of an electric vehicle gearbox as the research object, the dynamic models of the gear transmission system are established, and the shell is imported to complete the overall assembly of the gearbox. The gearbox is simulated and calculated.

The experimental results show that the proposed method can effectively enhance the fault-tolerance in the process of parameter self-tuning by means of fuzzy control. Its stability is superior to the reference results, and it has reliability.

Port tanker is an important part of the development of port industry. The guarantee of deck electrical system of tanker is an important prerequisite to ensure the normal operation of tanker. When the traditional electrical system support technology detects the electrical system in the process of support, there is a high data packet loss rate, and the service life of the electrical system of the tanker after the application of the traditional support technology is short. In view of the above problems, the deck electrical system support technology of the port tanker will be studied. Firstly, the evaluation system of electrical system safety early warning index is established, and the operation state detection information of electrical system is counted. According to the detection information, combined with the electrical system safety early warning index system, the electrical system abnormal state part of the fault detection. According to the test results, the maintenance and repair of deck electrical system and the research on the support technology of deck electrical system of port tanker are completed. The experimental results show that the study of the electrical system support technology in the use process, has a lower packet loss rate, and the application of research support technology after the electrical system service life is longer.

(eds.), Global Topics and New Trends in Coastal Research: Port, Coastal and Ocean Engineering. Journal of Coastal Research, Special Issue No. 103, pp. 397–401. Coconut Creek (Florida), ISSN 0749-0208.

Aiming at the problem that conventional detection technology has a weak ability to track and identify targets, a new detection technology of void temperature field inside hot hull forgings is researched. Based on the radial basis function, using the technology, a void temperature field measurement model for the hot forgings inside the hull is established. The mathematical solution is used to set the temperature field detection limit conditions. By adjusting the tracking angle, the position of the abnormal heating node inside the hot forging is tracked to achieve accurate detection of the temperature field type. The experimental results show that compared with the conventional detection technology, the temperature field detection technology of the research has a stronger ability to track the target, and the test results obtained are more practical. It can be seen that the new temperature field detection technology can be applied to the detection of the void temperature field inside the hot hull forgings at this stage.

In view of the poor structural stability of port pile foundation at present, the key technology research of port pile foundation construction based on mechanical analysis is put forward. According to the construction characteristics of ports, the settlement-displacement relationship of soil mass on pile side is analyzed. The pile-soil contact model is constructed based on the settlement calculation results of single pile. The ultimate Punching Strength of the bearing layer at the end of the pile is determined by considering the punching failure of the hard bearing layer and the strength failure of the soft underlying layer. Suitable proportional value is obtained by static equilibrium condition calculation, and key technology research of port pile foundation construction based on mechanical analysis is completed. The experimental results show that the soil pressure exertion coefficient of the pile foundation structure designed by the proposed technology is stable, and the change trend of the passive soil pressure coefficient is basically the same as that of the active soil pressure coefficient. It can be verified that the stability of the designed pile foundation structure is significantly improved compared with the structure designed by the comparison methods.

(eds.), Global Topics and New Trends in Coastal Research: Port, Coastal and Ocean Engineering. Journal of Coastal Research, Special Issue No. 103, pp. 412–416. Coconut Creek (Florida), ISSN 0749-0208.

In view of the poor accuracy of the traditional calculation method for the mechanical load of the full rotation crane ship, an automatic calculation method for the mechanical load of the full rotation crane ship based on the flow function theory is proposed. Based on the hydrodynamic model and flow function theory, the motion response of the super large full rotation crane ship Lanjing in irregular waves is calculated. Based on Morison equation and current function theory, the nonlinear wave mechanical load of the full rotation crane ship is calculated. The calculation results show that the method can accurately calculate the mechanical load of Lanjing. It can be concluded that with the decrease of the diameter of Lanjing pile, the wave peak point is gradually shifted to the wave peak position, and the lag phenomenon of nonlinear wave force peak is weakened. At the same time, the method can effectively calculate the wave mechanical load of Lanjing in towing and operating conditions.

According to the characteristics of high alkalinity and humidity in the coastal area, the self-excited vibration subsoiler is designed, and the subsoiling mechanism is designed as layered structure. The LS-DYNA explicit dynamics analysis program was used to simulate the working process of non-vibration and vibration subsoiling respectively. In the process of subsoiling, the action process of two kinds of subsoiling mechanism on soil, the stress change of subsoiling mechanism and soil respectively, and the mechanism of soil crushing of soil vibration are studied. It can be seen from the analysis that under the condition of vibration, the resistance of the soil to the subsoil shovel is reduced, the shear force of the subsoil shovel to the soil is increased. The soil debris is more uniform, there is no fracture phenomenon in the upper and lower layers of soil, and the subsoil effect is better.

(eds.), Global Topics and New Trends in Coastal Research: Port, Coastal and Ocean Engineering. Journal of Coastal Research, Special Issue No. 103, pp. 431–435. Coconut Creek (Florida), ISSN 0749-0208.

As the global climate continues to change, the demand for water resources in human society has been continuously expanding. Water shortages, frequent water pollution and natural disasters have become more and more serious. The issue of water resources security has aroused widespread concern in society. At present, the vulnerability of water resources is the main criterion for measuring the security status of water resources. The vulnerability assessment of water resources mainly studies the current vulnerability of water resources in the region and can reflect the degree of damage to water resources. The adaptive management is to improve the safety of water resources and optimize the future choice of water resources in the study area. Therefore, the assessment of water resources vulnerability combined with adaptive management is an important means to improve the safety of water resources. This article first defines the vulnerability and adaptive management of water resources in the basin based on the existing research results and the particularity of the water resources in the basin, and elaborate their connotations in detail. A water resources vulnerability assessment system based on DPSIR conceptual model is proposed. Secondly, by analyzing the influencing factors of water resources in the river basin, using the projection pursuit model and accelerated genetic algorithm (RAGA), a functional model of water vulnerability assessment based on RAGA projection pursuit was established. Finally, taking Hubei Province as an example, an empirical analysis was conducted to evaluate the vulnerability of water resources in Hubei Province, and a strategy for adaptive management of water resources was proposed.

Based on the logistic model, a new nonlinear dynamic model of marine plankton ecosystem is established considering the fishing behavior and the weakening effect of pollution on plankton and the self purification ability of plankton ecosystem. The dynamic characteristics of the model are analyzed by using the adaptive fuzzy variable structure control method, and the stability conditions of the marine planktonic ecosystem are obtained. On this basis, the adaptive fuzzy variable structure control of the system is designed. Finally, the feasibility and validity of this method for the study of marine planktonic ecological model are verified by numerical simulation.

(eds.), Global Topics and New Trends in Coastal Research: Port, Coastal and Ocean Engineering. Journal of Coastal Research, Special Issue No. 103, pp. 442–446. Coconut Creek (Florida), ISSN 0749-0208.

The Minnan area is located in the east of Fujian Province, close to the mountains and the sea, with superior geographical position and good ecological environment. It is the pioneer of green development in Fujian Province. Entropy method is a comprehensive evaluation index method of objective weighting, which has been widely used in the field of ecological environment. In this study, we use entropy method to calculate the environmental development level of Minnan area. Through the analysis of the empirical results of green environment development, we found that the level of green development in Xiamen is higher than that in Quanzhou, Zhangzhou, and the three cities in Minnan area are all inclined to the development of economic indicators. To this end, we suggest that the three cities in Minnan area should pay attention to the coordinated development of economic indicators, social indicators and environmental indicators, strengthen cooperation among the three cities, and generate useful insight for relevant departments to create a new development path of green industry.

In: Yang, Y.; Mi, C.; Zhao, L., and Lam, S. (eds.), Global Topics and New Trends in Coastal Research: Port, Coastal and Ocean Engineering. Journalof Coastal Research,Special Issue No.103,pp.447–452. Coconut Creek (Florida),ISSN0749-0208.

It has become an important means to improve the ecological environment in China by introducing social capital into eco-environmental projects, which has made some achievements but also accumulated great risks. The social capitals who cooperate with the government form a complex network of relations by jointly participating in projects or cooperating with the same local government. The risk caused by the deterioration of the operation of some node enterprises in the network may have a negative impact on the affiliated enterprises. Based on scale-free network transmission dynamics and epidemiology theory, the risk contagion model of affiliated enterprises in government-enterprise cooperative network under complex network is constructed. The impact of risk contagion coefficient, government relief coefficient and relief success coefficient on network risk contagion is explored. An empirical analysis is made with the data of affiliated enterprises in the government-enterprise cooperative network in the field of ecological construction in China. The results show that the probability of risk contagion has a non-linear and non-monotone effect on the network risk contagion, and the government relief has no significant inhibition on the risk contagion. Also the intervention effect has a positive effect on the risk contagion, and there is a superposition effect with the intervention intensity.

In: Yang, Y.; Mi, C.; Zhao, L., and Lam, S. (eds.), Global Topics and New Trends in Coastal Research: Port, Coastal and Ocean Engineering. Journal of Coastal Research, Special Issue No. 103, pp. 453–457. Coconut Creek (Florida), ISSN 0749-0208.

Artificial underwater illumination has a wide range of applications in coastal zone research, marine engineering, marine resource exploration and development, and marine ecological environment monitoring. In this article, the distribution of spectral irradiance has been discussed for an underwater light field generated by an underwater LED light source. Theoretical representations of the spectral irradiance have been derived according to physical principles and underwater spectral irradiance measurement have been accrued out along the optical axis of the light source and in the vertical plane perpendicular to the optical axis. Experimental results show that the spectral irradiance along the optical axis of the light source decays with respect to the distance, following the law of square attenuation and exponential attenuation. The irradiance in the vertical plane approximately matches the Gaussian distribution.

In: Yang, Y.; Mi, C.; Zhao, L., and Lam, S. (eds.), Global Topics and New Trends in Coastal Research: Port, Coastal and Ocean Engineering. Journal of Coastal Research, Special Issue No. 103, pp. 458–463. Coconut Creek (Florida), ISSN 0749-0208.

Water is an important social and economic resource for the sustainable development of mankind. This paper measures water use efficiency (WUE) of 106 cities in Yangtze River Economic Zone (YREZ) of China during 2006-2017 based on undesirable super-efficiency EBM-DEA model which takes sewage and social output into consideration. The results show that: (1) On average, WUE (technical efficiency, TE) of the YREZ does not reach efficient level, of which the west performs best among the three regions. Furthermore, pure technical efficiency (PTE) in the middle and west as well as scale efficiency (SE) in the east is constraint factor of their WUE respectively. (2) WUE in most cities is found above 0.4, and in a few cities is found efficient. (3) It must be noted that all capital cities' technical efficiency are revealed to be restrained by their SE. (4) Whether on overall level or regional level, WUE has been decreasing over time except for 2017, but the annual decreasing rate is becoming smaller and smaller and even convert to increasing rate in 2017. (5) The change of WUE mainly depends on efficiency change, and the deceasing of it should be attributed to technology regress. (6) More attention should be paid to the east whose total decreasing rate is largest and annual decreasing rate fluctuates greatest over time. These findings may provide a scientific basis for further studies on city level WUE and practical water resource management in the YREZ.

(eds.), Global Topics and New Trends in Coastal Research: Port, Coastal and Ocean Engineering. Journal of Coastal Research, Special Issue No. 103, pp. 464–468. Coconut Creek (Florida), ISSN 0749-0208.

The water-tightness measurement of a non-return tap is complex in testing condition, difficult in infliction of pressure, long in period of observation, low in measuring precision, easy in specimen destruction and so on, there is not an indoor testing apparatus of water-tightness for the non-return tap in water resources engineering. A specimen was fixed with a gate-type frame and a fixing apparatus of auto lifting and falling, the hydraulic pressure for measuring was controlled by an automatic system of pressure control, the measuring of water-tightness was carried out with a piezometer, a piezometric tube, an electromagnetic flowmeter based on analysis of the water-tightness of the non-return tap, and the corresponding testing method was carried out. The test showed that the specimen could be fixed with the fixing apparatus, the needed hydraulic pressure for measurement could be controlled by the automatic system of pressure control, the indexes of water-tightness for a non-return tap could be accurately measured, thus some difficulties were overcome such as complexity of testing condition, difficulty of load infliction, long period of observation, low precision of test and so on, it could be used to measure the water-tightness for the non-return tap. The method can be used to measure the water-tightness and evaluate the engineering quality of the non-return tap.

Tang, H. and Li, D., 2020. Spatial distribution characteristics of fringe villages of archipelagic city: A case study of Zhoushan. In: Yang, Y.; Mi, C.; Zhao, L., and Lam, S. (eds.), Global Topics and New Trends in Coastal Research: Port, Coastal and Ocean Engineering. Journal of Coastal Research, Special Issue No. 103, pp. 469–473. Coconut Creek (Florida), ISSN 0749-0208.

From the perspective of the spatial distribution of villages, Zhoushan, as a rare archipelagic city in China, has its own distinct characteristics in the development of urban fringe villages. On the one hand, the development of urban fringe village is affected by the connection between the village and the central urban area, on the other hand, it is also affected by its multi island and coastal geographical conditions. In this study, 54 urban fringe villages representing Zhoushan are selected, which represent a relatively high level of development in the local edge villages. In this paper, the spatial analysis of Zhoushan urban fringe village is carried out by Arc GIS 10.6, including the nearest neighbor index, geographic concentration index and kernel density. The research shows that the sample distribution of Zhoushan urban fringe villages is relatively uniform, and the development of Zhoushan urban fringe villages is relatively balanced. In the sample, most of the urban fringe villages far away from the central urban area are transformed into tourist destinations, which is related to the fact that although they are far away from the central urban area, they are still close to the sea and have rich coastal tourism resources. However, coastal tourism is not the only transformation option for the urban fringe villages near the central urban area, so many related samples have not become tourist destinations. The historical and cultural villages in the urban fringe villages are distributed in the southwest of Zhoushan. They can make use of their own historical and cultural characteristics to compete with the urban fringe villages in the north.

Wang, X.; Wei, G.; Wang, S.; Yang, Y.; Du, F., and Wang, B., 2020. Impact of large cooling tower on atmospheric dispersion of effluent from coastal nuclear power plant. In: Yang, Y.; Mi, C.; Zhao, L., and Lam, S. (eds.), Global Topics and New Trends in Coastal Research: Port, Coastal and Ocean Engineering. Journal of Coastal Research, Special Issue No. 103, pp. 474–478. Coconut Creek (Florida), ISSN 0749-0208.

In order to improve the simulation quality of atmospheric dispersion on coastal nuclear power plant, computational fluid dynamics (CFD) method was used to simulate the impact of large cooling tower on the diffusion of gaseous effluent from coastal nuclear power plant. The simulation results show that when the release point is directly in front of the cooling tower, with considering the natural ventilation effect of the cooling tower, the axis concentration of the effluent is significantly reduced by about 1 to 2 orders of magnitude. Compared with different ambient wind speeds, the cooling tower has a more significant effect on the diffusion under low wind speed. For the ground release, atmospheric stability conditions have little effect on the concentration distribution. On this basis, a correction of the Gaussian model for the cooling tower effect is proposed. The atmospheric diffusion parameters in the Gaussian plume model can be given by three distance segments, which are 0-240 m, 240-270 m and above.

Li, S.; Zhang, X., and Ding, Z., 2020. The impact of public participation on the environmental impact assessment of marine engineering. In: Yang, Y.; Mi, C.; Zhao, L., and Lam, S. (eds.), Global Topics and New Trends in Coastal Research: Port, Coastal and Ocean Engineering. Journal of Coastal Research, Special Issue No. 103, pp. 479–483. Coconut Creek (Florida), ISSN 0749-0208.

Marine engineering can bring huge economic benefits, but in the process of using marine engineering to develop marine resources, there is often excessive demand and consumption of environmental resources by the development and construction subjects, and there are endless incidents of marine environment pollution or destruction. The environmental impact assessment (EIA) of marine engineering can analyze, predict and evaluate the possible environmental impact of marine engineering, and put forward countermeasures to prevent or mitigate the adverse environmental impact. Because the marine engineering can bring huge economic benefits, and local governments need to make achievements, the environmental impact assessment often become a mere formality, or avoid the important and dwell on the trivial. By establishing reputation model and signal model, we find the public's positive attitude, extensive participation and active action in environmental impact assessment of marine engineering can prevent the EIA from being false, and make the EIA play a better role in the decision-making process.

(eds.), Global Topics and New Trends in Coastal Research: Port, Coastal and Ocean Engineering. Journal of Coastal Research, Special Issue No. 103, pp. 484–489. Coconut Creek (Florida), ISSN 0749-0208.

In order to provide theoretical support for the formulation of optimized measures of stand spatial structure, 15 sample plots are set up in Daweishan Nature Reserve, Longhushan national forest farm in Yuanjiang City and Lutou national forest farm in Pingjiang County to analyze and evaluate the stand spatial structure of natural secondary forest around Dongting Lake. After determining the spatial structure unit of trees by Voronoi diagram, the five indicators including mingling degree, neighborhood comparison, openness comparison index, neighborhood pattern and angle competition index are segmented to correspond to the five grades of stand spatial structure divided by the combination of qualitative and quantitative methods. Then through the comprehensive assessment on stand spatial structure by entropy weight-cloud model, the fifteen plots are evaluated as grade III and grade IV, respectively accounting for two-thirds and one-thirds of all plots, which indicates that the reasonable stand spatial structure of natural secondary forest around Dongting Lake is above the average. As a new evaluation method of stand spatial structure, the entropy weight-cloud model has solved the issue of qualitative and quantitative conversion, and objectively calculate the weights of indicators, so as to enrich the evaluation methods of stand spatial structure, overcome the one-way evaluation by single indicator, improve the objectivity and scientificity of evaluation results, and provide theoretical basis for the scientific guidance of stand spatial structure optimization.

Journal of Coastal Research, Special Issue No. 103, pp. 490–495. Coconut Creek (Florida), ISSN 0749-0208.

Quantitative study on the system of variable-rate fertilizer in agricultural production helps to reduce use of fertilizer, preserve green environment, increase the economic benefit of agriculture, and achieve the sustainable development of agriculture. This study combined the conventional PID control and fuzzy control algorithms with the optimization of genetic algorithm to design the variable-rate fertilizer system. Then, with the prescription map, the speed and swath width of fertilizer application equipment were configurated to accurately control the amount of granular fertilizer applied in a field. The design was mathematically modeled and simulated with the programs of MATLAB (Math Works, Natick, MA). The conclusion as follows: not only do fuzzy control and the PID control based on the combination of genetic algorithm have quicker response speed and robust of anti-parameters change, it achieve high precision control and finally meets the requirement of the experiment purpose. With different quantitative granular fertilizer and speed of tumbrel, the model can well simulate precise control of variable-rate of the granular fertilizer of the tumbrel and uniform fertilizing.

Kong, Q., 2020. The dilemma and way of fighting climate change in coastal areas in China in the view of ecological justice. In: Yang, Y.; Mi, C.; Zhao, L., and Lam, S. (eds.), Global Topics and New Trends in Coastal Research: Port, Coastal and Ocean Engineering. Journal of Coastal Research, Special Issue No. 103, pp. 500–505. Coconut Creek (Florida), ISSN 0749-0208.

The righteousness of fighting climate change has become a call and demand, mainly because climate change itself is unfair to developing countries, which involves the issue of ecological justice. At present, the biggest obstacle in the process of fighting climate change on a global scale lies in the differences between the north and the south and the different positions of different countries (groups), which can be overcame by establishing feasible emission reduction standards to achieve distribution justice, and fulfilling the commitments of capital and technology in developed countries to realize corrective effect.

Zeng, X. and Zhao, Y., 2020. The characteristics of rural settlement landscape in hilly area from the perspective of ecological environment. In: Yang, Y.; Mi, C.; Zhao, L., and Lam, S. (eds.), Global Topics and New Trends in Coastal Research: Port, Coastal and Ocean Engineering. Journal of Coastal Research, Special Issue No. 103, pp. 506–510. Coconut Creek (Florida), ISSN 0749-0208.

This paper is based on the landscape changes of rural settlements in the hilly areas of a province and the income of local people. The analysis was carried out, and the ecological landscape of the village was not reformed and the living conditions of the villagers were used as the control group. After the partial agricultural landscape was reconstructed in some areas, the landscape of the village and the living conditions of the villagers in the hilly area were used as the first experimental group to reconstruct part of the section. After the natural landscape, the landscape of C village and the living conditions of the villagers in the hilly area are the second experimental group. The reconstruction of the partial landscape of some areas and the living conditions of the villagers in the hilly area and the living conditions of the villagers are the third experimental group. The experimental data were collected and the experimental data were analyzed. The experimental results show that the rural settlements in the hilly areas can improve the living conditions of the villagers from the perspective of partial ecological environment. The experimental results show that the hilly areas will promote their economic income and improve their quality of life from the perspective of partial ecological environment.

Ma, Y.; Cao, H.; Zhang, L., and Fu, Z., 2020. Relationship between local government competition, environmental regulation and water pollutant emissions: Analysis based on mediating effect and panel threshold model. In: Yang, Y.; Mi, C.; Zhao, L., and Lam, S. (eds.), Global Topics and New Trends in Coastal Research: Port, Coastal and Ocean Engineering. Journal of Coastal Research, Special Issue No. 103, pp. 511–515. Coconut Creek (Florida), ISSN 0749-0208.

Water has been further polluted by “development at the cost of environment” since the reform and opening up. The emission of water pollutant in China is closely related to political economy, and local government competition is an important factor in pollution control. This paper specifically studied direct and indirect effects of local government competition on environmental pollutant emissions, and tested the nonlinear relationship between local government competition and water pollutant emissions. The results show that local government competition has been characterized by “race to the top”, which has direct and indirect effects. Formal environmental regulation plays a mediating role in the process of local government competition affecting water pollutant emissions, but informal environmental regulation does not play such a role. With increasing formal environmental regulation, local government competition is playing a bigger role in suppressing water pollutant emissions.

Floating offshore tidal current turbines are usually moored in the sea, which will endure the wind-wave-current load in a long term. Power production of the tidal current turbine will result in extra excitation force acting on the platform, which will make the motion prediction and positioning system design of the floating platform more complicated. In order to predict the motion response of a floating tidal current power station, a coupled motion prediction method is established to explore the coupled interaction among the platform, the turbine and the mooring system. The turbine influence is considered as added mass and damping acting on the platform. Results shows that the fitted hydrodynamics agree well with numerical simulation results. The operation of the tidal turbine can increase the surge amplitude and pitch angle of catamaran, and the mooring line tension will increase as well. The research can provide some reference for motion response prediction and mooring positioning of a floating tidal current power station.

The generation of walking patterns based on predictive control realizes the control with the use of future information, which also conforms to the principle of human walking process in accordance with future road conditions. However, the target ZMP of the predictive controller is always off-line programmed in advance. Due to the model error and environmental disturbance, gait tracking error of the biped robot in walking process is inevitable. Considering that human-simulated intelligent control (HSIC) can well suppress error, this study designed a human-simulated predictive control (HSPC) system by combining HSIC and predictive control. The control variables can be switched based on ZMP error state so as to realize the control of dynamic system. Therefore, actual ZMP output can well track the expected value of variable ZMP to realize the stable walking of the biped robot, and also adapt to the complex environments such as port robot operation. Finally, the effectiveness of the designed HSPC was validated through simulation.

Due to the poor transition effect of traditional ship track control, the shipping pressure is too large. The research on extrapolation algorithm of ship track smoothing based on spline theory is proposed. Based on the principle of spline fitting, a three degree of freedom motion model of ship's horizontal plane is established to analyze the force on the ship in the process of motion, so the motion equation is obtained. The extrapolation algorithm is used to analyze the intersection of wave gates. Considering the actual situation and the influence parameters, the research on extrapolation algorithm of ship track smoothing based on spline theory is completed. The control experiment is designed to compare the track control effect of the proposed algorithm with that of the traditional algorithm. The results show that the combination of the spline theory and the extrapolation method results in a higher fit between the control curve and the actual route, which is obviously superior to the traditional results, and the control effect of the ship track is optimized.

The traditional architectural form feature analysis method has a high error and a long time for the regional architectural analysis. Therefore, a method based on the regional characteristics of the coastal area architectural form feature analysis is designed. By analyzing the environmental characteristics of the coastal cities, analyzing the sky visibility and the quality of the greening system, the architectural characteristics of the area are preliminarily obtained, and the quantitative analysis of the architectural form characteristics is further completed by using the data obtained from remote sensing images. Finally, by setting up observation points, the architectural form parameters of the area are obtained, and the architectural form layout characteristics corresponding to different land use attributes are analyzed. So far, the design of analysis method of architectural form characteristics in coastal areas based on regional characteristics has been completed. The experimental results show that the average error of the design method is less than that of the traditional method and the analysis time is less than that of the traditional method.

The traditional information resource sharing model of coastal city library has slow response time in resource sharing, so an information resource sharing model of coastal city library based on cloud computing is designed. By making the matching rules of association data, the close correlation degree of heterogeneous digital resources are calculated. Considering the data density, the information resources of coastal city library are collected. On this basis, the data is integrated and collected and the information of coastal city library is managed, such us the operations of resource downloading and uploading, so as to complete the information resource sharing of coastal city library based on cloud computing. The experiment shows that, in the case of less and more shared resources, the sharing time of the information resource sharing model of the coastal city library based on cloud computing is less than that of the traditional model, which can meet the needs of information resource sharing.

(eds.), Global Topics and New Trends in Coastal Research: Port, Coastal and Ocean Engineering. Journal of Coastal Research, Special Issue No. 103, pp. 923–927.

With the rising efficiency demand and intelligence trend of the container terminals (CTs), horizontal transportation could be a vital bottle neck of terminal operations. In artificial terminals, Internal trucks (ITs) is the most common and versatile horizontal equipment, the efficiency of ITs affects horizontal transportation efficiency greatly. With sharing ITs among multiple CTs located nearby, the IT resource could be allocated in a wider range to further improve handling efficiency. In this paper, we proposed a multi-objective MIP model for IT allocation, and a Hungarian Algorithm is introduced to solve the problem in a preferable period of time. Numerical experiment shows that, the proposed model and Hungarian Algorithm are efficient to achieve the optimal allocation solution.

Linear orthomorphic permutations (orthomorphisms) of an integer residue class ring I (n) is studied to their structure and properties, and the definition of a linear orthomorphic matrix on the integer residue class ring I (n) is set up in detail. The counting formula and the generating algorithm of linear orthomorphic matrices are created. All of this can provide a theoretical basis for studying the properties and structures of linear orthomorphisms over the finite commutative ring I (n) in cryptography. We can design linear p-permutations in cryptography using the linear orthomorphisms because of their well diffusibility and perfect balance.
