摘　　要：在设定了地下水各污染物的"基准"浓度情况下,用污染物的实测浓度相对值替代水质污染损害率公式中的浓度监测值,采用遗传算法(GA)对公式中的参数优化,得到了38项指标都适用的水质污染损害率和污染损害指数公式,提出用广义模糊对比法对污染损害分指数进行赋权的新方法,计算水质综合污染损害指数。利用该法对河池市4个水厂的地下水水源进行水质综合评价分析,取得了较好的效果。Each pollutant of groundwater is given a benchmark concentration. The measured concentration is substituted by relative value in the water quality pollution harm rate formula. By optimizing the parameters in the formula with GA, the water quality pollution harm rate and pollution harm index formula applicable to all 38 indexes are acquired. A new generalized fuzzy contrast method is proposed to obtain the weights of pollution harm subindexes and calculate the water quality comprehensive pollution harm index. This method had been used to assess the groundwater quality for the four water supply plants in Hechi City, rendering fairly good resuits.
