| 摘 要： | 对雅砻江某电站的水样进行多元统计分析，水样的八个指标Q型聚类，对地表水及地下水进行了水文地质初步分类，主因子分析反映了与地下水形成作用有关的三个重要的水文地球化学作用，即岩溶作用、黄铁矿的氧化作用以及地下水的溶滤作用。结合多元统计结果以及本区的水文地质条件，对地下水系进行了分类。

| Abstract: | In this paper,the method of multivariate statistical analysis is applied to the water samples collected from one power station over the Yalong river.By means of the Q-type clustering analysis of water sample index marks, the hydrogeological classification of the surface water and ground water are prelimilarly reached. The results of the principal factor analysis show three important hydrogeochemical processes ,that is ,karst process ,iron pyrites oxidization and the dissolution of ground water. With the analysis results and conbining the hydrogeological condition,the ground water system of the research aera is classified. |
