摘　　要：为识别河流健康状况、探讨河流受损的可能成因,以三峡库区坝首第一大支流香溪河为研究对象,考虑流域内人类活动分布和自然属性分布特征,将其划分为4个研究评估河段,基于层次关联指标体系,运用模糊数学综合评价法开展健康状态研究。结果表明,构建评价指标体系时,应优先考虑维持河流自身生态功能的相关指标;香溪河整体评估结果为非常健康,但模糊数学综合评价法对计算指标之间的侧重性差异则体现了不同河段评价结果的异质性;整体而言,该方法能较好地评估河流的健康水平,识别重点因子。In order to identify the river health status and explore the possible causes of river damage,the Xiangxi River,the first largest tributary of the dam head in the Three Gorges Reservoir,was taken as the research object.Considering the distribution characteristics of human activities and natural attributes in the basin,the Xiangxi River was divided into four evaluation river sections.Based on the hierarchical correlation index system,the fuzzy mathematics comprehensive evaluation method was used to study the health status of Xiangxi River.The results showed that when constructing the evaluation index system,priority should be given to the relevant indicators that maintained the ecological function of the river itself.The overall health status of Xiangxi River was very healthy,but the difference between the calculation indexes of the fuzzy mathematics comprehensive evaluation method reflected the heterogeneity of the evaluation results of different river sections.On the whole,this method could better evaluate the health level of rivers and identify key factors.
