摘　　要：运用模糊综合评价法评价了衡水湖三个主要监测站点(洼内、小库和冀县)在2000—2007年水环境质量的变化过程。研究结果表明2001—2005年衡水湖整体水环境质量没有得到明显的改善,2006年后,衡水湖洼内和冀县监测站点水环境质量有了改善,基本满足Ⅲ类用水标准。三个监测站点的主要贡献污染物也有所差异。2006年洼内监测站点水环境主要贡献污染物为氨氮,贡献率为0.621。其余年份均为高锰酸盐指数,2000—2005年及2007年贡献率为0.5左右。小库监测站点水环境的主要贡献污染物2003年,2004年,2005年,2007年均为总磷。2000年,2001年,2002年,2006年为氨氮且2000年和2006年贡献率分别达到0.58,0.838。冀县监测站点水环境主要贡献污染物2000年,2001年,2002年,2006年为氨氮,但2001年,2002年贡献率不到0.4,相较于2000年和2006年较低。2003年为总磷,贡献率为0.38。2004,2005,2007为高锰酸盐指数,贡献率分别为0.61,0.50,0.38。并在水环境质量分析的基础上剖析了衡水湖水环境污染的原因,给出衡水湖今后保护和管理的建议。The fuzzy comprehensive evaluation method was applied to evaluate the water environmental quality of three main monitoring sites （i. e. , Wanei, Xiaoku and Jixian） of Hengshui Lake during the period from 2000 to 2007. The results showed that water environment quality of Hengshui Lake had not been improved during the period from 2001 to 2005, however, water environment quality of both Wanei and Jixian monito- ring sites had been improved after 2006, and basically met class Ⅲ criteria of water quality. The main contri bution ratios of these pollutants at three monitoring sites also differed each other. As for Wanei site, the major pollutant in 2006 was ammonia nitrogen with a contribution rate of 0. 621 and permanganate index was lhe major pollutant in the rest years. From 2000 to 2005, the contribution rates were 0.52, 0.48, 0.44, 0.46, 0.66, and 0.70, respectively and it was 0.45 in 2007. At Xiaoku site, the major pollutant in 2003, 2004, 2005, and 2007 was total phosphorus, the respective contribution rate was 0. 56,0. 46,0. 38, and 0.42, re- spectively, however, the major pollutant was ammonia nitrogen in 2000, 2001, 2002 and 2006, the respective contribution rates were 0.58 （2000）, 0.36 （2001）, 0.43 （2002）, and 0.838 （2006）, respectively. In contrast, the major pollutant at Jixian site was ammonia nitrogen with the contribution rates of 0.60 （2000）, 0.38 （2001）,0.39（2002）, and 0. 583（2006） and it was total phosphorus with contribution rate of 0. 38 in 2003, whereas it was permanganate index in 2004, 2005 and 2007 with the respective contribution rate of 0.61,0.50, and 0.38, respectively. On the basis of water environmental quality analysis, the reasons for the water environment pollutionof Hengshui Lake were analyzed and some suggestions for the ecological conservation and water quality management of this lake were also put forward.
