忻州市滹沱河主要支流生态系统健康评价

摘要

In this article the health risk evaluation of 4 main tributaries of Hutuo River in Xinzhou was made by comprehensive health index based on water quantity, water quality, biological species and water connectivity. It was concluded that the overall index of Yangwu River was 34.1, which meant the river was in morbidity status.Muma River's was 47.1, sub-health status.Yunzhong River's was 15.7, on the verge of collapse, and Qingshui River's was 75.0, health status generally.Summarily, the ecological health level of the river basin was not optimistic as a whole.There were differences between the rivers.Yunzhong River and Yangwu River needed to be restored urgently.%采用河流生态健康评价体系中的水量、水质、生物、水体连通性4个指标，运用综合健康指数法分别对忻州市滹沱河4条支流进行生态健康评价。结果表明：阳武河总指标数值为34．1，呈病态状态；牧马河总指标数值为47．1，呈亚健康状态；云中河总指标数值为15．7，呈濒于崩溃状态；清水河总指标数值为75．0，呈基本健康状态。可见，该区域河流生态健康水平整体不容乐观，同时各河流具有差异性，尤其是云中河、阳武河生态修复非常迫切。
