摘要
同一级别不同地区的地下水水质会因评价指标数值的差异而有所差别,将集对分析法运用到地下水水质评价中,可以先通过计算评价样本与评价指标之间的联系度对样本作初步的排序,再对样本作进一步的同一、差异、对立的集对分析以判断出评价样本的等级。研究结果表明:评价结果与采用其他评价方法时基本一致,且集对分析法简便、实用,计算结果客观、稳定,是一种有效的水质评价方法。
The groundwater quality of different regions at the same classification may be different because of the different evaluation indicators. The paper applies set pair analysis method to the evaluation of groundwater quality. The samples were firstly classified preliminarily by calculating the relation degree between the samples and evaluation indicators. Then the samples were ranked through farther same, difference and antagonism set pair analysis. The application result showed that the evaluation result of set pair analysis method was consistent with that of other evaluation methods. Furthermore, the set pair analysis method is simple and practical , and its outcomes are objective and stable. So, it is an effective evaluation method of water quality.
