地下水水质指数计算的一个通用公式

A Current Formula of Index for Calculation of Groundwater Quality

适当设定各项地下水水质指标的某一“参照值”,引入相对于“参照值”的指标相对值替代污染损害指数公式中的指标实测值,采用遗传算法优化指数公式中的参数,得出对地下水所有水质指标都能通用的水质指数计算公式。该公式应用于若干地下水水质评价结果与实况相符。该公式形式简单,易于计算,方便实用;并具有客观性、可比性和通用性特点。

Supposing' reference value' of each index of groundwater quality and substituting the relative value for the monitoring value of factor in the formula of pollution harm index, a current index formula of groundwater quality are derived by using the genetic algorithm to optimize the parameters. The formula was verified by a case analysis of groundwater quality assessment. The index formula shows simple, easy to be calculated, simple to be used and objective, universal and comparative.
