Ecosystem Health Assessment and Prediction Analysis of Wuqia County Watershed
摘要
Abstract
In order to facilitate the management and planning of the ecological environment in Wuqia County, the index system of e-cosystem assessment for the regional watershed was established through the PSR model of ecosystem health assessment, the analytic hierarchy process was used to determine the index value and its weight, and the gray prediction model was used to forecast the e-cosystem health of Wuqia County. The comprehensive evaluation results showed that the health status of the ecosystem of Wuqia County from 2008 to 2015 was 'deteriorating'gradually,and it degraded to 0.176 in 2014,reaching the 'sick'state.According to the gray prediction model, the ecological forecast of the basin in near 5 years in the future will decrease to 0.306, 0.289, 0.273, 0.258,0.244 respectively;the river basin ecosystem will be in an unhealthy state and have a tendency to develop morbidly.The threat will be more and more serious,the regional watershed ecosystem needs for protection and management.The research provided the ba-sis for coordinating the relationship between regional development and ecological environment.关键词
