摘　　要：巢湖是属于国家"三河三湖"重点水污染防治流域之一。近年来,湖体营养过程加剧,生态环境受到明显损害,制约了流域社会经济的可持续发展。巢湖湖区水中高锰酸钾、总氮、总磷含量分别为4.9、2.48、0.227mg/L,水质类别为劣ⅴ类(重度污染);表层沉积物中总氮、总磷含量平均值为1065、587 mg/kg。要实现流域水资源的可持续利用,必须加快水污染综合治理。文章分析了巢湖污染现状,结合实际情况提出了治理对策。Chaohu Lake belongs to the ＂three rivers and three lakes＂ of major water pollution prevention valleys. In recent years, the nutrition process of the lake became serious the ecological environment was damaged obviously, which has restricted the sustainable development of socio--economy. The content of potassium permanganate, total nitrogen, total phosphorus in the water are 4.9,2. 48, 0. 227mg/L, respectively, the water quality belongs to the specific weight pollution（V）. At the sediment surface layer , the average content of TN,TP are 1065.587 mg/kg. To achieve the sustainable use of water basin, we must accelerate the comprehensive management of water pollution. The article analyzed the pollution status of Chaohu Lake, and proposed specific measures in accordance with the actual situation.
