Analysis Of Ecological Security Carrying Capacity Based On PSR Model

With the continuous development of economy,social attention to ecology is also increasing,and ecological security has become the focus of attention.The research on the bearing capacity of ecological security has important strategic significance for regional ecological security and sustainable development,is an important basis for the evaluation of ecological security in the sample area,and can also reflect the overall impact of human social and economic activities on the ecology.Based on the research results of the research group of ecological security carrying capacity,this paper selects Boxing County in Shandong Province,which has the overall distribution of ecological resources at the national average level,as the research sample area.At the same time,Boxing County is one of the most potential cities for economic development and ecological protection in Shandong Province,which has certain research value.In this paper,entropy weight method and expert method are used to build the evaluation model,and the ecological security index is calculated.Compared with the ecological security index,using PSR model to analyze and explain the data,comparing the security index of Boxing County with the average value of Shandong Province,the result of PSR comprehensive evaluation index is 0.28,lower than 1,which proves that the comprehensive pressure caused by Boxing County in Shandong Province is higher than the response degree that Shandong Province can bear,which is generally unsafe,and the overall forestry resources are not enough to cope with the current situation The ecological pressure state of the whole province;and analyze the sample areas and put forward countermeasures and suggestions to promote the development of ecological civilization construction in Boxing County,Shandong Province.
