摘　　要：为了建立科学合理、普适通用和计算简便的地下水水质评价模型,在适当设定指标参照值Cj0和指标的规范变换式基础上,提出了一个适用于规范值的多指标地下水水质的韦伯指数公式的一般表达式。采用具有全局优化的混合蛙跳算法对公式中的参数进行优化,得出优化后对33项地下水指标皆共同适用的的地下水水质单指标评价的韦伯普适指数公式。该公式还被应用于地下水水质实例评价,其评价结果与其它方法的评价结果基本一致,从而表明:该指数公式为地下水水质评价提供了一个简便、实用的新公式。A universal index formula suited to the normalized values of multi-indexes was proposed in order to design a scientific,reasonable,universal,common,and easy-operating groundwater quality assessment model.This proposed formula was based on the setting reference values and normalized transformation form of indexes.At the same time,the parameter involved in the formula was also optimized by using Shuffled Frog Leaping Algorithm（SFLA） which has optimization in total real field.The results show that the optimized universal Weber＇s index formula is suitable to 33 index items for groundwater quality assessment.Furthermore,this formula was applied to the practical groundwater quality assessment.The assessment results are proved to be coincident with other evaluation methods,and also in correspondence with the actual conditions.It is sufficiently indicated that this formula is a new simple and practical formula for groundwater quality assessment.
