摘要：

在河段尺度下，采用指标评价法对太子河流域的水生生物多样性维持、生境维持、水环境支持和水文支持4项生态功能进行评价，排序求和得到河流的主导功能和综合功能评分. 结果表明：全部河段可评定为4个综合生态功能等级，整体上呈现由山区向平原区递减的趋势. 结合综合生态功能和主导生态功能评价结果，提出了6项河流生态管理策略.其中，对于水生生物多样性维持功能和生境维持功能的河段，管理策略以生态管理为主，即“生态保护”、“生态维持”和“生态修复”；对于水环境支持功能和水文支持功能的河段，管理策略则以开发管理为主，即“限制开发”、“优化开发”和“开发利用”.

Abstract: By the method of index evaluation at reach scale, this paper evaluated the ecological functions of aquatic biodiversity maintenance, habitat maintenance, water quality sustainment, and hydrological support of the river system in Taizi River basin of North China. The dominant ecological functions and the total ecological function were determined after sorting and summing. All the reaches in the basin were divided into four hierarchies of ecological functions. Overall, the total ecological function showed a spatially degrading trend from the mountainous region to the plain. Based on the evaluation results of the total function and dominant functions, six ecosystem management strategies were proposed. For the reaches with the functions of aquatic biodiversity and habitat maintenance, the primary ecological management strategies included ecological conservation, ecological maintenance, and ecological restoration; for the reaches with the functions of water quality sustainment and hydrological support, the primary strategies of ecological management included limited development, development optimization, and exploitation.
