基于PSR模型的渤海海洋生态红线区管控评价研究

Research on management and control evaluation of the marine ecological red line region in Bohai Sea based on PSR model

为客观评价我国海洋生态红线区管控效果,本文通过建立海洋生态红线区管控评价体系,运用PSR模型对渤海区域及三省一市(山东省、辽宁省、河北省和天津市)海洋生态红线区管控效果进行评价。结果表明渤海区域海洋生态红线区的管控情况总体上持续改善,压力层稳定性较差,状态层不断优化,响应层受政策影响较大。其中渤海区域压力层主要受山东省人口、工业影响,状态层的变化主要来自辽宁省丰富自然资源的作用,响应层的改变主要来自山东省对于生态安全做出的努力。最后根据各省市海洋生态环境现状从海洋保护区管控、海洋保护区限制开发等方面提出了管理建议。

In order to objectively evaluate the management and control effect of marine ecological red line zone in China, the management and control evaluation system for marine ecological red line zone was established to evaluate the effect of Bohai Sea region and three provinces and one city(Shandong, Liaoning, Hebei and Tianjin), and timely to find the problems in the management and control. PSR model was used to evaluate the management and control effect of Bohai Sea marine ecological red line area, and empirical analysis was made on three provinces and one city. The results show that in the overall situation, the management and control continues to improve in Bohai Sea, the stability of pressure layer is poor, the state layer is constantly optimized, and the response layer is greatly affected by the policy. Among them, the pressure layer of Bohai Sea is mainly affected by the population and industry of Shandong Province, the status layer is mainly derived from the rich natural resources of Liaoning Province, and the response layer is mainly derived from the efforts made by Shandong Province for ecological security. Finally, according to the current situation of marine ecological environment in various provinces and cities, management suggestions are put forward from the aspects of management and control as well as the restricted development in the marine protected areas.
