摘要

西苕溪是太湖上游的重要支流

由于人类活动的干扰

河流健康状况受损

功能下降。基于河流健康的内涵

选取河流形态结构、河流社会经济功能和河流生态功能3类诊断河流健康状况的1级指标。针对西苕溪流域健康现状和可获取的资料

构建了诊断西苕溪健康状况的18个2级指标。选用多目标多层次模糊模型诊断西苕溪健康状况

建立了各指标标准特征值

确定了各指标权重。计算和分析结果表明

西苕溪综合健康状况大部分处于中等和良好状态

河流形态结构的改变和较差的水质是影响其健康的主要原因。西苕溪流域的生态修复措施主要包括创建多样性生物栖息地

有效控制面源污染

建立水库适应性管理程序等。

Abstract

The Xitiao River is the main branch of Taihu basin.Due to the disturbance of human

the river health has been damaged and its functions have been reduced gradually. Based on the meaning of river health

3first-grade diagnostic indexes were selected

namely river morphology

social economic function and ecologic function. 18 second-grade diagnostic indexes were then determined by considering the present health status and obtained data of the Xitiao River. A multi-objective and multi-layer fuzzy model was used to diag-nose the river health and determine the index standard character values and the index weights.Through cal-ulation and analysis

the Xitiao River health was almost in the middle and good condition. The main factors were the changing river morphology and worse water quality.It is suggested that the main restoration meas-ures are to create diversity habits

control non-point source pollution and built adapting management pro-grams of reservoirs
