Abstract

The Dengsha estuary area is taken as the research area, and the value of marine ecological services is calculated from the perspective of opportunity cost, the exploitability of marine units is analyzed, and the current situation of marine utilization is analyzed and evaluated. By constructing an evaluation model of exploitability and utilization of sea area units, combining with GIS and model formulas, the value of marine ecological services and the exploitability and utilization of each type of sea area in sea area units are calculated. The results showed that: The effective exploitation and utilization of fishery seas in Dengsha estuary ecological zone is basically realized, and the ineffective utilization of industrial and mining seas is the main cause of ecological loss. The layout of Dengsha estuary should be further optimized, and the layout far away from the ecological core area should be adopted to improve the comprehensive benefits of using the sea. Keywords—evaluation model of ecological benefit of sea area utilization; marine spatial planning; ecosystem service value

基于ESV的海域开发利用分析——以登沙口生态区为例

以邓沙河口地区为研究区，从机会成本的角度计算海洋生态服务价值，分析海洋单元的可利用性，并对海洋利用现状进行分析和评价。通过构建海区单元可利用性评价模型，结合GIS和模型公式，计算海区单元中各类海区的海洋生态服务价值和可利用性价值。结果表明:登沙口生态区渔业海的有效开发利用基本实现，工矿海的无效利用是造成生态损失的主要原因。应进一步优化登沙口布局，采取远离生态核心区的布局，提高利用海的综合效益。关键词:海域利用生态效益评价模型;海洋空间规划;生态系统服务价值
