分层聚类分析在水文地球化学分类中的应用

以福建省马坑矿区为例,对采集的水化学数据进行Q型聚类分析。分析结果表明,马坑矿区的地下水主要包括三种水化学类型:砂岩和花岗岩裂隙水类型、岩溶水类型及混合水类型,其中不同类型水的混合水与岩溶水距离较近,混合成因水(混合水)中又可细分为三种不同类型。通过分类大致了解区域不同含水层的水化学特征,为找出混合成因水,解决不同含水层的连通情况提供了可靠依据。

Application of Hydrochemistry Classifing with Hierarchical Cluster Analysis

On the base of essential principle of space and distances,cluster analysis is a method of multivariate statistical analysis.This article takes the Makeng mining area as an example,which is located in Fujian province,and uses the cluster analysis method on the collected data of the water samples.The result indicates that the water hydrochemical types could be divided into three types: fissure groundwater,karstic groundwater and mixing water,among which the distance between mixing water and karst water is rel...
