摘要
地下水化学特征合理的分类有利于更好地认识区域水文地质条件。本文通过采用spss聚类分析软件对观音峡背斜区地下水水化学特征进行分类研究。当并类距离取2时,将研究区所取水样分为5类,研究区地下水化学特征主要表现:岩溶水化学类型主要为HCO3·SO4-Ca或SO4·HCO3-Ca型水,碎屑岩裂隙水化学类型则主要为HCO3·SO4-Ca·Mg型水。
As rational hydro-chemical classification of groundwater helps to understand regional hydro-chemical environment better, the paper makes a hydro-chemical classification analysis of groundwater in anticlines along Guanyin Gorge by using SPSS software. When the clustering distance is two, groundwater in studied area is divided into 5 classifications and the hydro-chemical characteristics of karst water are HCO3 ＆#183;SO4 - Ca or SO4 ＆#183;HCO3 -Ca while that of fissure water are HCO3 ＆#183;SO4 -Ca＆#183;Mg.
