With the rapid development of China's economy and the continuous degradation of the ecological environment,ecological security is gradually being valued.As Zhejiang Province is located in the south wing of the Yangtze River Delta along the southeast coast of China,the most important of its ecological security is the marine fishery ecological security.Therefore,in order to carry out a comprehensive evaluation of the marine fishery ecological security in Zhejiang Province,explore the mechanism that affects the marine fishery ecological security,and propose corresponding control measures to achieve the rational use and sustainable development of marine fishery resources in Zhejiang Province..In this paper,the marine fishery ecological safety evaluation system in Zhejiang Province is constructed.Based on the research of other scholars,this article first elaborates the concept of marine fishery ecological security and the theory of sustainable development.Secondly,it analyzes the current status of marine fishery ecological security in Zhejiang Province and analyzes its influencing factors.Based on this,a marine fishery ecological security evaluation system based on the PSR model was constructed.The index system weights corresponding to each subsystem of Marine fishery ecological security pressure,state and response in Zhejiang province were obtained by using the comprehensive weight method,and then the safety indexes of Marine fishery ecological security pressure,state and response were calculated by using the comprehensive index method.And the calculation of the comprehensive index of marine fishery ecological security in Zhejiang Province in the10-year period from 2009 to 2018 has been calculated,which indicates that the environmental pressures on Zhejiang's oceans have gradually eased.The obstacle degree model was used to analyze and determine the main influencing factors and degree of Marine fishery ecological security in Zhejiang province.According to the research of this article,from the organization's management and construction,security assurance The seven aspects of system construction,system level,monitoring angle,transformation and upgrading of industrial development methods,removal of traditional concepts,andrestoration of ecological environment are proposed in Zhejiang Province.
