Abstract

Abstract

Based on the PSR model, 14 evaluation indexes, including sewage treatment rate, water quality status, biodiversity and environmental investment index were selected to establish the water environment health evaluation system of Pan'an Lake wetland, and their weights of indexes were determined by analytic hierarchy process. The health status of wetland water environment was classified into 5 levels from very healthy to morbid, and then the fuzzy comprehensive evaluation method was used to evaluate the health status of Pan'an Lake wetland water environment. The evaluation results showed that the water environmental health index of Pan'an Lake wetland was 2.8166, belonging to sub-health state. The stress index score was 1.7405, which was in disease status. The status index score was 3.2563, belonging to the sub-health state. The response index score was 2.4483, which was between sub-health state and disease state.
