Sustainable Development Of Coastal Areas Research Articles

Current issues of using the coastal areas of the Baltic sea

The article proves that the existing threats to coastal marine areas that are notable for significant vulnerability to human activity require changes in Russian water legislation, which must introduce the category “coastal territories” and clarify the regime of permissions, restrictions and prohibitions within them. This will make it possible to more effectively regulate the economic, environmental and social aspects of the use and protection of the marine environment and coastal areas. For Russian water law, a number of legal structures that are successfully used in Polish water law are of interest, including the allocation of two zones with special legal regime on the coast, environmental planning of the use and protection of the coast and sea waters, as well as a set of measures to ensure sustainable development of coastal areas.

Analysis on the utilization and carrying capacity of coastal tidal flat in bays around the Bohai Sea

The utilization and protection of tidal flat play a crucial role in the sustainable development of coastal areas. This study aims to propose an evaluation index system model for the carrying capacity of the tidal flat resources in bays around the Bohai Sea. Indexes are selected under the framework of DSI (Drivers-State-Impact), considering the socio-economic driving factors, resource conditions, the influence of shoreline change on hydrodynamic environment and the utilization type associating with possible ecological impact. Basic indexes are quantified using publicly available statistical information, hydrodynamic numerical simulation and satellite image interpretation, while the weight of each index is determined using the entropy weight method. The historical changes and future trends of shoreline and the utilization type of the coastal tidal flat in last decades are analyzed, and the carrying capacity of the tidal flat resources around the Bohai Sea has been evaluated. The coast around the Bohai Sea is divided into three areas, the Liaodong Bay, the Bohai Bay and the Laizhou Bay. The results show that the carrying capacity of the Laizhou Bay is better than the other areas. Moreover, the carrying capacity of the three areas showed a large decline from 2003 to 2013, while the decline slowed from 2013 to 2018 and is expected to increase slightly from 2018 to 2028.

Ordenamiento y gestión del territorio en zonas costeras con turismo residencial. El caso de Región Este, Uruguay

Sun and beach tourism associated with residential modality, is one of the most important activities in Uruguay. The urban occupation characteristics of the East Region coasts (Maldonado and Rocha departments) generate from the beginning impacts of great magnitude. Between 1997 and 2003 the first two instruments of land planning and management, involving the defence, protection and sustainable development of coastal areas, were created: the Environmental Impact Assessment (of national application) and the Coastal Ordinance of the department of Rocha. This paper analyzes their current results, through the transformations in the territory and their socio-environmental impacts. By means of quantitative, qualitative and spatial analyses, the successes and failures in the conception and implementation of these instruments are revealed.

Analysis of Water Resources Carrying Capacity of Coastal Cities along the Yangtze River Based on PSR Model

Xu, M.; Chen, M.; Li, Y., and Jiang, Y., 2020. Analysis of water resources carrying capacity of coastal cities along the Yangtze River based on PSR model. In: Wan, Z. (ed.), Coordinated Sustainable Development in Coastal Areas: Environment and Economy. Journal of Coastal Research, Special Issue No. 109, pp. 110–113. Coconut Creek (Florida), ISSN 0749-0208.The coastal cities along the Yangtze River are relatively rich in water resources but the economy is developed, therefore the contradiction between economic society and water resources still exists. According to the characteristics of coastal cities along the Yangtze River, this paper constructs an evaluation index system for water resources carrying capacity based on the Pressure-State-Response(PSR) framework. Based on typical examples of Nantong City's 2010-2018 relevant index data, using the Analytic Hierarchy Process (AHP) model and with the help of YAAHP software, the following conclusions are obtained: 1) There are pressure state response mechanisms in each element of the water resources carrying capacity system of coastal cities along the Yangtze River. The key to the operation of the system is the limit of water resources carrying capacity. 2) Domestic water demand has the greatest impact on water resources carrying capacity. Domestic water demand has the greatest impact on the carrying capacity of water resources, but in the allocation of water resources, it is important to optimize the production water use of the industrial economy and provide sufficient funds to guarantee.3) During the period of 2010-2018 in Nantong City, with the development of industrial economy, the discharge of industrial wastewater was significantly reduced. Moreover, the investment in the treatment of industrial pollution, especially industrial waste water pollution, has been significantly increased, and the carrying capacity of water resources has been constantly optimized.

Analysis of the Coupling Mechanism Between Economic System and Water Resource System in Jiangsu Coastal Area

Chen, H. and Chen, M., 2020. Analysis of the coupling mechanism between economic system and water resource system in Jiangsu coastal area. In: Wan, Z. (ed.), Coordinated Sustainable Development in Coastal Areas: Environment and Economy. Journal of Coastal Research, Special Issue No. 109, pp. 223–227. Coconut Creek (Florida), ISSN 0749-0208.The research on the coupling relationship between economic systems and water resources systems has always been a hot topic in the academic field. Due to the characteristics of its own economy and water resources environment, it is particularly necessary to study the coupling mechanism between the economic system and the water resources system in coastal areas. Based on the coupling system perspective, this paper constructs the coupling mechanism model of the economic system and the water resources system. On this basis, the author obtains the following conclusions through the research on Jiangsu coastal areas: (1) There is a complex coupling mechanism between the economic system and the water resources system. When the operation of the two systems conflicts, the water resources system will send a response signal to the economic system. (2) The coupling state between the economic system and the water resource system in Jiangsu coastal area showed a better coordinated situation from 2000 to 2011. From 2012 to 2014, the coupling between the economic system and the water resources system weakened and was in a state of basic coordination. Therefore, the industrial structure of this region needs to be adjusted and the resource-friendly economic model needs to be established.

Moreover, the stochastic dynamic responses of the system subjected to random excitation are obtained. The theoretical and numerical results show that there is random Hopf bifurcation occurs in the system, which causes the system's motion switch between the slight oscillation and large-amplitude vibration.

Corporate Innovation and Capacity Utilization in China's Coastal Areas: Governance under the Context of Environmental Regulation

Zheng, C.; Zhang, Y., and Chen, K., 2020. Corporate innovation and capacity utilization in China's coastal areas: Governance under the context of environmental regulation. In: Wan, Z. (ed.), Coordinated Sustainable Development in Coastal Areas: Environment and Economy. Journal of Coastal Research, Special Issue No. 109, pp. 197–205. Coconut Creek (Florida), ISSN 0749-0208.Previous empirical analysis of scholars found that environmental regulation has a significant impact on overcapacity and industrial structure adjustment, higher environmental regulation will increase overcapacity, while moderate environmental regulation will optimize industrial structure. Moreover, in the industrial enterprises above the scale, the industrial structure has an intermediary effect between environmental regulation and overcapacity. This paper studies corporate innovation and capacity utilization under the background of environmental regulation. Taking publicly listed firms in China's coastal provinces from 1990 to 2017 as our sample, the corporate innovation under environmental regulation has been significantly enhanced， and hence alleviates overcapacity in China. This means that environmental regulation promotes the formation of a virtuous circle. To firms with high-quality innovation, the positive effect is more pronounced. Moreover, to firms with bad internal governance, specifically to firms with high agency cost, the capacity utilization is low, which means serious waste of resources and environment. Meanwhile, external governance from the stock market, specifically analyst coverage and institutional ownership, fails to intensify the positive effect of corporate innovation on capacity utilization.

Research on the Minimum Span of Constructions Crossing Natural Curve River

Ai, W.; Liu, H., and Zhu, P., 2020. Research on the minimum span of constructions crossing natural curve river. In: Wan, Z. (ed.), Coordinated Sustainable Development in Coastal Areas: Environment and Economy. Journal of Coastal Research, Special Issue No. 109, pp. 8–12. Coconut Creek (Florida), ISSN 0749-0208.The problem of determination method on the span of constructions crossing curved river is necessary to be researched not only because its close relation to navigation safety, but also because no clear method has been put forward so far, the minimum span of structures across natural curve river, which is considered as channel width (not considering the influence of tidal currents) is studied in this paper. From the perspective of navigation safety, the method of determining the minimum span of constructions crossing natural curve river can be obtained by establishing mathematical calculation models of flow-induced drift of natural curve and the range of turbulent flow around construction piers. The results show that the span of constructions crossing natural curved river is closely related to the navigation width of the ship, ship's drift distance induced by flow and wind, turbulent range of construction pier etc. The more the above factors are, the larger the minimum span of constructions crossing curved river is.

Coconut Creek (Florida), ISSN 0749-0208.Focusing on the difficulties of fluvial sedimentary stratigraphic correlation and sedimentary evolution study in a complex fault-block area, taking the meandering sedimentation of Neogene Ming2 (Nm2) oil group of block 1 of Gangxi oilfield as an anatomical object, by applying well-seismic integration based on the comprehensive analysis of geological, coring, well-logging and seismic data in the oilfield development area, this paper establishes the correlation profiles and accurate stratigraphic frameworks of cyclic stratigraphic division in the study area, and divides Nm2 oil group into 3 mid-term base level cycles (MSC1, MSC2 and MSC3) and 22 short-term base level cycles (corresponding to 22 subzone). The plane sedimentary microfacies distribution of every single layer is characterized based on the study of single-well sedimentary microfacies; meanwhile, the vertical evolutionary patterns of meandering channel sandbody in the study area is established, that is, along with the rise and fall of the base level cycle, it is the increase and decrease in A/S cyclic change that controls the lateral distribution characteristics and vertical overlap pattern of channel sands. Acuurate cycle stratigraphic analysis and sedimentary microfacies study provide the geological basis for oilfield management in the middle and late stage of oilfield development.

Ecological Development Strategy of Coastal Sport Projects of Jiangsu Province

Zheng, W., 2020. Ecological development strategy of coastal sport projects of Jiangsu Province. In: Wan, Z. (ed.), Coordinated Sustainable Development in Coastal Areas: Environment and Economy. Journal of Coastal Research, Special Issue No. 109, pp. 152–158. Coconut Creek (Florida), ISSN 0749-0208.Jiangsu is located in the Yangtze River Delta and many cities represented by Lianyungang and Yangzhou have coastal resources. Therefore, the coastal area of Jiangsu has unique ecological environment conditions, and its future development potential is huge. In order to promote a sustainable future, through the investigation of the ecological development of coastal sports, this paper finds that the current environmental protection status of coastal sports tourism is not optimistic by means of questionnaire survey and expert interview. This is mainly reflected in the low environmental awareness of employees and tourists, and the insufficient environmental protection of facilities in sports. Using PEST model, it can be found that ecological sports projects in Jiangsu coastal area need to be promoted at the administration level, with emphasis on increasing investment in technological innovation and environmental protection training.

Wang, Q.; Yu, X., and Zhang, C., 2020. The analysis and prediction of China's gross ocean product in coastal areas---based on the ARMA model. In: Wan, Z. (ed.), Coordinated Sustainable Development in Coastal Areas: Environment and Economy. Journal of Coastal Research, Special Issue No. 109, pp. 51–56. Coconut Creek (Florida), ISSN 0749-0208.In the 21st century, more and more countries attach importance to the marine economy, and even many countries regard the development of the marine economy as a national key strategy. The marine economic development in China's coastal areas has been developing rapidly since the 1990s, but at the same time, the government needs to pay attention to the current transformation of the marine economic structure and the lack of new growth points. In this paper, the ARMA model is used to carry out regression analysis on China's total Gross Ocean Product (GOP) from 2001 to 2016 and forecast the value from 2020 to 2022.

Coastal Service Industry, Industrial Structure Optimization and Environmental Governance: An Empirical Analysis Based on Chinese Coastal Cities

Wu, S.; Zhou, Y., and Yan, W., 2020. Coastal service industry, industrial structure optimization and environmental governance: An empirical analysis based on Chinese coastal cities. In: Wan, Z. (ed.), Coordinated Sustainable Development in Coastal Areas: Environment and Economy. Journal of Coastal Research, Special Issue No. 109, pp. 114–120. Coconut Creek (Florida), ISSN 0749-0208.This paper analyzes the relationship between industrial structure transformation and pollutant emission changes in 86 cities in coastal areas of China from 2013 to 2017 and proves whether the optimization of the industrial structure of the service sector can play a positive role in restraining environmental pollution. The empirical results show that when the industrial structure or economic activity structure of the city changes towards the service industry, the pollution of the whole city will be restrained and the environmental quality will be improved. It is believed that the optimization of service structure can restrain the scale of pollution, mainly because the optimization of the service industry reflects the positive effect of industrial agglomeration on environmental quality and environmental quality. The optimization of the service industry can promote the technological progress and diffusion of industrial economic activities through the agglomeration of industry, and provide the possibility for the concentration of environmental protection production technology and pollution treatment facilities. Besides, the optimization of the service industry can produce knowledge spillover between enterprises through cooperative agglomeration and improve the current situation of environmental pollution by improving the effect of technological innovation level of enterprises.
