摘　　要：根据辽河流域水系特征选取COD,BOD5,NH3-N等6个典型水质指标,以综合水质标识指数评价法对辽河流域主要干流水质进行评价。以此为基础,结合多元统计分析方法对辽河流域主要干流水体中主要污染物进行源解析。结果表明,辽河流域中、下游水体中度污染比较严重,辽河流域水体有3种典型污染物,对整个辽河流域污染的贡献率分别为56.85%,18.23%和17.51%。Based on the water system characteristics of the Liao River Basin,six typical water quality indexes,including COD,BOD5,NH3-N,were selected.The water quality of the main river in the Liao River Basin was assessed using the integrated water quality index evaluation method.The source apportionment of main pollutants in the main river of the Liao River Basin was conducted using the multivariate statistical analysis method.The results show that the water pollution in the middle and lower reaches of the Liao River Basin is more serious.In the Liao River Basin,there are three kinds of typical water pollutants,whose contribution rates were 56.85%,18.23% and 17.51%,respectively.
