摘要
河流健康是人类赖以生存和高速发展的必要条件,对其进行评价研究有利于河流生态环境可持续发展。采用层次分析法和模糊综合评价隶属度方法,对丹江流域河流健康状况进行评价。建立由河流自身状况、河流生态状况、社会经济服务3个准则层和19个指标层组成的丹江流域河流健康评价指标体系。进而确定各项指标的评价权重,得出水污染指标权重值较其余18个指标权重值大,是河流健康评价的首要因素。依据指标权重和隶属度矩阵评价结果显示河流比降、含沙量、防洪调蓄等9个指标为健康,河床形态、河岸带植被、水污染等8个指标为亚健康,水域面积宽窄和珍稀生物2个指标为疾病,综合评价丹江流域健康状况为亚健康状态。因此,修复和保护丹江流域水环境与水安全对南水北调水源区具有重要的意义。
River health is a necessary condition for human survival and rapid development.The evaluation study of river health is beneficial to the sustainable development of river ecological environment.Based on AHP and fuzzy comprehensive evaluation membership degree method,the river health status of the Danjiang River Basin was evaluated.The evaluation index system of river health in Danjiang river basin is established,which is composed of three criteria layers and19criteria layers of river self-condition,river ecological condition and social and economic service.Then the evaluation weight of each index is calculated,and the result shows that the weight of water pollution index is higher than the other of18indexes,which is the primary factor of river health evaluation.By combining matrix scoring with index weight,nine indexes,such as river specific drop,sediment content,flood control and storage,were found to be healthy.Eight indexes,such as river bed morphology,riparian vegetation and water pollution,were subhealthy.Two indexes,narrow water area and rare organisms,were disease.The comprehensive evaluation results showed that the health status of Danjiang River Basin was sub-healthy.Therefore,the restoration and protection of Danjiang water environment and water security has an important sense in the source area of South-to-North Water Transfer Project.
