基于PSR模型的宁夏清水河流域生态系统健康评价
Research on Ecosystem Health Evaluation of Qingshui River Basin Based on Pressure-State-Response Model
摘要
Abstract
The study on the health assessment of watershed ecosystem is of great significance in water pollution prevention and ecological en-vironmental protection.According to the actual situation of the Qingshui River basin,the study built the Qingshui River basin ecosystem health evaluation index system based on the PSR model,adopted hierarchical analysis to determine the weights of each evaluation index and adopted the comprehensive evaluation index method to evaluate the ecological health of the Qingshui River basin.The results show that from 2000 to 2020,the average of comprehensive evaluation index of ecosystem health of the Qingshui River basin increases from 0.245 0 to 0.593 3,and the overall health level of the basin has evolved from a general pathological level to a sub-healthy level.Among them,the comprehensive evaluation index of the basin ecosystem health in 2010 is increased slightly compared with that in 2000,and the ecological environment of the basin has been improved to a certain extent.The comprehensive evaluation index of the basin ecosystem health in 2020 is increased signifi-cantly compared with that in 2010,which indicates that the ecological environment of the basin has been significantly improved and the eco-system structure and function are more perfect,and the ecological environment has been affected by human activities.The ecosystem health index of the basin in 2020 will be significantly larger than that of 2010,indicating that the ecological environment of the basin has been sig-nificantly improved,and the ecosystem structure and function are relatively perfect,and have a certain degree of resilience after being dis-turbed by human activities.关键词
