基于PSR模型的浙江海洋生態(tài)安全評價研究
[Abstract]:Marine ecological security is an important part of ecological security in Zhejiang Province. In order to accurately control the extent of marine development, it is necessary to objectively evaluate the current marine ecological situation. Based on the research of many scholars, this paper expounds the connotation and characteristics of marine ecological security. After following the principle of index selection and the advantages and disadvantages of comparative evaluation model, the index system based on PSR model is constructed, and the analytic hierarchy process (AHP) is adopted. The general state of marine ecological security in Zhejiang Province in recent years is comprehensively evaluated. The results show that the comprehensive index of Zhejiang marine ecological security is rising in general and decreasing occasionally, and the marine ecological security of Zhejiang is in a general situation at present. Based on the analysis of the impact mechanism of marine ecological security in Zhejiang Province, the main measures of ecological security regulation and control are as follows: reducing the pressure of ecological security, repairing ecological function and strengthening the response efficiency. In order to reduce the pressure of ecological security, we should carry out the exploitation of marine resources with restraint. When we look at the relationship among economic development, social progress and ecological security, we should proceed from a long-term perspective. In order to realize the purpose of ecological security, we should pay attention to the environmental pollution from the ideological point of view, not only to control the existing phenomena, but also to strictly control the pollution sources and stop the pollution at the source. At the same time, the ecological restoration of Zhejiang ocean can bring into full play the role of ocean park and nature reserve, improve the ecological compensation mechanism, can deal with the shortage of funds and the abuse of marine resources to the greatest extent. To increase the efficiency of ecological response is mainly to improve the ecological consciousness of the public by improving the construction of management system, strengthening the enforcement of law and enhancing the public's ecological consciousness.
