摘　　要：本文采用单因子指数法、综合污染指数法及主成分分析法,对柳州市8处地表水水质数据进行综合评价。结果表明:单因子指数法计算结果均为Ⅱ类水质;综合污染指数法与单因子指数法计算结果趋势基本接近,但不能直接判断水质级别;主成分分析法可以分析水质的主要影响污染物。因此,综合考虑3种评价方法对地表水水质进行评价,可以获取更多的潜在信息。The single factor index method,comprehensive pollution index method and principal component analysis method were used to comprehensively evaluate the surface water quality data of 8 sites in Liuzhou.The results show that:the single factor index method of the calculation results areⅡclass quality;the result of the comprehensive pollution index method is close to that of the single factor index method calculation,but it can't judge the water quality directly;principal component analysis can be used to analyze the main pollutants affecting water quality.Therefore,the comprehensive evaluation of surface water quality of the three evaluation methods can obtain more potential information.
