Average comprehensive pollution index method was used to assess the present situation of water environment. Major pollutants were screened by studying the sharing ra tio of each pollutant. Meanwhile, the co rrelation between major pollutants was analyzed. The purpose of this study is to reveal major pollutants and associated sources of Sailimu Lake basin. Results demonstrated that water quality of Sailimu Lake basin was good. Water prehensiv e index of lake, lakeside, and rivers was , and , respectively. Average tr ophic state index of Sailimu Lake is , indicating a poor nutrient level. Major pollutants included pH, fluoride, ammonia nitrogen, total nitrogen, total phosphorus, BOD and 高锰酸盐指数.
