摘　　要：为评价河流生态系统的健康状态,构建了包括水文特性、水质特性、河流地貌特性、生物特性和社会经济特性5方面、含36项指标的全国河流健康评价全指标体系,并将每个指标的健康状况分为5个级别。文中提出了基于柯西分布的模糊评价模型,并对指标值处于不同健康状况级别的模型参数进行区分,可以更合理地评价不同级别的健康状况。A complete index system for river health assessment is established,which includes 36 indices in 5 aspects,i.e.the characteristics of hydrology,water quality,river geomorphology,biology characteristics and socioeconomic status.The river health condition is divided into 5 grades.The model for assessment is proposed based on Cauchy fuzzy theory,and membership degree function parameters are developed according to different assessment grades to make the assessment results of river health more reasonable.
