摘　　要：利用模糊综合评价矩阵构造适用于确定权重的判断矩阵,并用遗传算法对判断矩阵的一致性进行检验、修正和计算各指标权重的新模型。通过对乌审旗图克镇地下水监测资料进行对比分析,确定评价指标体系,并应用此模型进行实例计算。分析表明,该方法具有普遍性、可靠性和客观性,在地下水质评价中具有广泛应用价值。A new model that is using the fuzzy comprehensive evaluation matrix to build the judgment matrix which can be used to calculate each index weight and using genetic algorithm to examine and revise the consistency of judgment matrix and to determine each index weight in judgment matrix, was put forward. On the basis of comparing and analyzing the monitoring data of groundwater quality in Tuke Town of Wushenqi, the evaluation index system was determined, and this new model was applied in calculations. The results show that this method has universality, reliability, objectivity, and wide application value in groundwater quality evaluation.
