摘要
在传统的DRASTIC指标评价法的基础上,联合集对分析对地下水脆弱性进行评价。将7个不同评价指标分成5级,利用集对分析建立评价指标与评价等级之间的联系度U,从而确定地下水脆弱性的等级。将DRASTIC指标评价法与集对分析法联合应用的好处是:一定程度避免了原有评价方法中人为因素的干扰。新的评价体系具有计算简便,评价合理,结果较为客观等优越性。
Based on traditional DRASTIC index evaluation method, a new method combined with set pair analysis is used to assess groundwater vulnerability. Every evaluation indexes is divided into five levels. The connection degree between evaluation indexes is established through set pair analysis to determine the groundwater vulnerability degree. The new method can avoid the interference of human factors in a certain degree. The new evaluation system has advantages of simple calculation and objective result.
