摘　　要：以湖南省郴州市的东江湖为研究对象,运用模糊综合评判模型对3个监测断面的24个监测因子进行综合评判。结果表明:东江湖水质总体状况较好,符合功能区水环境质量标准,其中1月、4月、7月东江湖水质对I类水的隶属度最高,10月对Ⅱ类水的隶属度最高。水质污染因子中最重要的污染因子为铅,与东江湖流域内存在金属尾矿区有关。评价结果为污染控制提供了科学依据。The water quality of Dongjiang Lake in Chenzhou,Hunan was studied in this paper. Comprehensive evaluation of three monitoring cross sections and 24 monitoring factors was conducted by fuzzy mathematical comprehensive evaluation model. The evaluation result showed that,the water quality of the Dongjiang Lake was in good condition,met the standards of water environmental quality. The water quality of Dongjiang Lake in January,April,July was Grade Ⅰwhile in October was Grade Ⅱ. The most important pollution factor was Pb,may caused by the tailings in the watershed.
