Water resources carrying capacity of wetland conservation in Dongting Lake

Abstract

This paper studies the water resources carrying capacity of lake wetland tourism development. This paper studies by establishing DPSIR model. In this paper, several important factors influencing the water resources carrying capacity of lake wetland tourism development in each criterion layer are understood through DPSIR model, among which the weight value of surface water resources is 0.0367, the weight value of per capita water consumption in criterion layer is relatively large, 0.0369, the weight value of do in state value is 0.0450, the weight value of air quality excellent rate in criterion layer is 0.0400, and the weight value of sewage in response is 0.0367. Among them, the weight value of recycling amount is the largest, which is 0.0539. In addition, the order of weight of criterion layer is: state (0.2298) > driving force (0.1413) > response (0.1337) > pressure (0.1071) > impact (0.0753). It can be seen that the comprehensive weight of state subsystem is the largest.
