摘　　要：本文从水量、水质、生物状况、河道连通性4个指标出发,通过建立滹沱河忻州段的生态环境健康评价体系,对滹沱河忻州境内的4条断面进行了生态健康评价,旨在为滹沱河生态系统修复提供依据。结果显示:下茹越—西属留河段综合健康指数为46.7,生态健康呈亚健康状态;西属留—界河铺河段综合健康指数为36.1,呈病态状态;界河铺—济胜桥河段综合指数为29.0,呈病态状态;济胜桥—南庄段综合健康指数为70.4,呈基本健康状态。总体看滹沱河忻州段生态基本健康、亚健康、病态所占河长比例分别为13.4%、24.8%、61.8%,在空间上表现出差异性,即上段呈亚健康状态,中段呈病态状态,下段呈基本健康状态。因此,在具体实践中应该针对不同河段的生态健康水平,采取相适应的生态环境管理措施。Four indexes from the water quantity ,the water quality ,the biological status and water connectivity ,through the establishment of the ecosystem health evaluation system of Hutuo River in Xinzhou ,the ecosystems of the 4 sec‐tions of Hutuo river in Xinzhou were healthily assessed ,so as to provide the basis for the Hutuo River ecosystem resto‐ration. The results showed that the comprehensive health index of the stream segment from Xiaruyue to Xishuliu was 46.7 ,which was in the sub‐health state ,and that of the stream segment from Xishuliu to Jiehepu was 36.1 ,which was ill conditioned state ,and that of the stream segment from Jiehepu to Jishengqiao was 29.0 ,which was ill conditioned state ,and that of the stream segment from Jishengqiao to Nanzhuang was 70.4 ,which showed a basic health state. In general ,the stream‐length ratios of the state of ecological basic health ,sub‐health ,and ill conditioned state of the Hutuo river in Xinzhou were 13.4% ,24.8% and 61.8% respectively ,and there were great different in space ,that the upper was in the sub‐health state ,the middle was ill conditioned state ,and the downstream was in basic health state. Therefore ,in the concrete practice ,it should be aimed at the ecological health level of different streams ,and adopt the ecological environment management measures to adapt to the concrete.
