摘　　要：桂林市的东镇路水厂、东江水厂和瓦窑水厂是桂林市人民饮用水的主要来源,这三个水厂都是以漓江为取水水源。依据对三个水厂取水点2005年全年水质定期检测资料,采用单污染指数法评价单因子对环境产生的等效影响程度,采用综合指数法评价水质综合环境质量现状。分析评价结果表明:漓江市区江段三个检测断面石油类污染物、挥发酚等检测项目存在不同程度超标现象,其它项目基本满足《地表水环境质量标准》(GB3838—2002)中的第II类水质评价标准。总体上,东镇路水厂取水点的水质较好,东江水厂取水点的水质次之,而瓦窑水厂取水点的水质量差。研究结果表明,市区漓江江段整体的水环境质量受降雨量的影响很大,雨季污染情况较严重。Dongzhen Road Water Factory,Dongjiang Water Factory and Wayao Water Factory in Guilin are the main source of the people＇s drinking water. The year 2005 monitor data of the three water factories across the river section in Guilin is adopted. The single polutant exponent method to evaluate single factor of the equivalent effect degree to water environment, and the compositive exponent method to evaluate the water quality synthesis environmental quality condition are used . The result indicates that the petrolic pollutants in different degree . Other monitor factors basically satisfy the second water quality evaluation standard of The Quality Standard of Susface Water Environment （GB3838-2002）. The total results of the water environmental quality evaluation indcate that the water quality indicates that the water quality in Dongzhen Road Water Factory is good, Dongjiang Water Factorys＇s is not good as former＇s and Wayao Water Factorys＇ is not good as the other two＇s. The research also indicates that the water environmental quality of the Li River is greatlly affected by the rainfall, for the pollutant conditions are sever in rainy seasons.
