摘　　要：为了克服传统灰色聚类法用于地下水水质评价时需要设计众多白化函数的不足,提出在设定地下水各指标"参照值"和"规范变换式"基础上,将地下水指标按同级标准的规范值的接近程度进行归类。属于同一类的指标可设计相同的白化函数,从而大大简化了函数的设计工作量。指标规范化的灰色聚类方法应用于黑龙洞泉域的地下水水质评价,得出的评价结果与识别理论方法和加权优序法的评价结果基本一致,表明该方法应用于地下水质评价中具有简单实用的特点。In order to overcome the shortage of designing the numbers of whitening functions for traditional gray clustering method in the groundwater quality assessment,on the basis of setting ＂reference value＂ and ＂normal transformation＂ of each groundwater index,the indexes were classified according to the colse on extent of normalized inedx ralues in same grade.The same whitening function was designed if indexes belong to the same class,so as to simplify function design.Grey cluster method of indexes normalization was applied to the groundwater quality assessment in the Heilongdong Spring area.The result is accordance with that from the attribute recognition method and weighted optimum order method.The method exhibits the characteristics of convenience during calculation and commonness for groundwater qualit assessment.
