| 摘 要： | 运用主成分方法分析淮南矿区23个地下水样的7个水样指标，提取出4个主成分，应用聚类分析对该4个主成分的得分进行聚类。在此基础上，将主成分得分与其对应的特征值相乘，得到水质综合评价指数。聚类分析后水样划分为5类，对每一类的水质综合评价指数取平均值，从而确定水质等级。

| Abstract: | Seven water indexes of 23 groundwater samples which are collected in huainan minning area,are analyzed by using the principal component method,then,we extract four principal components,using cluster analysis to cluster the scores of them.Therefore,we can get the synthetic evaluation number of the water quality according to multiply each the principal component score with its total.By the method of cluster analysis,the water samples are divided into 5 clusters,then,calculating the average of the synthetic evaluation number in each cluster to define the rank of the water quality. |
