基于集对分析法的地下水水质综合评价研究

Study on the Application of Set Pair Analysis Method in Comprehensive Assessment of Water Quality

集对分析是研究客观事物之间确定性与不确定性联系的系统理论和方法。针对水质评价中各评价指标的不确定性,将集对分析理论应用于水质综合评价中。先通过计算评价样本与评价指标之间的联系度对样本做初步分类,再对样本做进一步的集对分析以判断评价样本的等级。研究结果表明:采用集对分析法进行水质评价准确可靠,计算结果客观、合理。

The method of set pair analysis is a with uncertainty between objective things. In view systematic theory and method to study the connection of certainty of the uncertainties of assessmend indexes, this theory is adopted in comprehensive water quality assessment.The samples are preliminarily classified by calculating the connection de-gree between the samples and evaluation indicators. Then the samples are further ranked through water quality clas- sification. The results show that the set pair analysis method for the groundwater quality assessment is accurate and reliable and its results are objective and reasonable.
