Spatial Zoning and Comparison of Mesoscale Coastal Waters Schemes

Abstract Comprehensive zoning of coastal waters based on the ecosystem is the key to the compilation and effective management of coastal waters spatial planning. In this study, a comprehensive zoning scheme was developed based on ecological zoning of the Marxan model and resource use zoning. Resource use zoning was then used as an ecological protection cost to optimize comprehensive zoning. By comparing and evaluating the spatial structure and benefits of comprehensive zoning optimized schemes, it was found to shorten the boundary length of the protection zone, increase connectivity, and reduce fragmentation between the protection zones. This study is significant in enriching and improving the theoretical and technical methodological system of city-level mesoscale coastal waters spatial planning in China, therefore improving the science and evaluability of planning, and providing spatial guidance and decision-making references for ecological environmental protection and the sustainable use of resources in the coastal waters of Nantong.
