Ecosystem Health Assessment Of Lake Scenic Spots

At present,with the rapid development of tourism industry,the development model of global tourism has been implemented in an all-round way,which brings opportunities and challenges to the healthy and healthy sustainable development of lake-type scenic spots(hereinafter referred to as lake-type scenic spots).Due to the intensification of human disturbance,the ecosystem health of Lake scenic spots is further threatened,which forces people to re-examine the contradiction between effective protection and development and utilization of Lake Scenic spots.Whether Lake scenic spots can achieve the ultimate goal of sustainable development depends essentially on whether their ecosystems are in a healthy and stable state.At present,the research on ecological evaluation of lake-type scenic spots is still relatively deficient;therefore,this paper combines the theory of ecosystem health with the sustainable development of lake-type scenic spots,and comprehensively evaluates the ecosystem health level of lake-type scenic spots,which not only enriches the research on ecological evaluation of lake-type scenic spots,but also provides some scientific theory and Practice for their scientific planning and comprehensive management.Firstly,this paper summarizes the deficiencies of the research on ecosystem health assessment of lake-type scenic spots and lake-type scenic spots through systematic analysis of the research results of ecosystem health assessment at home and abroad.Secondly,with the help of PSR model,the ecosystem health evaluation index system of lake-type scenic spots is constructed,and the ecosystem comprehensive health index of lake-type scenic spots is calculated.Number EHI is used as a parameter to evaluate the health level of ecosystem.Finally,the ecosystem health assessment system of Lake Scenic Spot Based on PSR model was applied to Longxu Lake scenic spot in Anhui Province.According to the comprehensive assessment of the ecosystem,the comprehensive health index(EHI)of the ecosystem in Delongxuhu Scenic Spot is 0.8216,and the health grade is grade I.The health index of each subsystem is 0.7704,0.8722 and 0.7942,respectively.The health grade of pressure subsystem,state subsystem and response subsystem is in order of grade II,grade I and grade II.On this basis,the comprehensive control strategy of ecosystem health in Longxuhu Scenic Area was put forward.In order to provide some theoretical guidance and scientific method basis for the sustainable development of Lake Scenic spots.
