基于聚类分析的华蓥山褶皱山系地下水水化学分类研究

Study on groundwater hydrochemical classification of Mount HuaYing fold based the Cluster Analysis

岩性、岩石结构、地下水径流条件等不同,地下水水化学组分差异较大。研究地下水的水化学组分,对掌握水文地质条件有及其重要的作用。通过聚类分析对华蓥山地区所取水样进行聚类,取并类距离d=9将22组水样分为5类,聚类结果反映该地区的岩溶水的水化学特征,结合分类能更清楚地掌握该地区同类泉点的补径排特征,进一步研究该地区的水文地质条件。

Due to difference of lithology, rock structure, groundwater flow conditions, the chemical components of ground- water water are different. So researching the chemical components of groundwater water is important to grasp the hydrogeologi- cal condition. In this paper, throughing cluster analysis to classify water samples collecting from Mount HuaYing region. Tak- ing class distance d = 9 divided 22 waters to five types, and achieved better explaining results. Clustering results reflect water chemical characteristics of karst water of the region, combined with classification can more clearly grasp the recharge, runoff and discharge characteristics of similar spring in the region. It has a very important significance to study the hydrogeological condition of the region.
