利用R型因子分析法对桂林寨底地下河水化学数据进行分析，识别出影响寨底地下河水质因素的4个主因子：因子1以Ca2＋、HCO3-和总硬度为主，表明方解石矿物的溶滤作用对地下水水化学组分的影响；因子2以K＋＋Na＋和Cl-为主，反映含水介质易溶盐对水化学组分的重要影响；因子3以SO2-4和NO3-为主，代表了人类活动（农药和化肥的使用、生活污水的污染）对地下水水化学组分的影响作用；因子4以pH和Mg2＋为主，反映了弱碱性水环境下白云石矿物的溶滤作用对地下水水化学组分的影响作用。

Hydrogeochemical data of Zhaidi underground river are analyzed using R-mode method.Four main factors which affect the quality of underground river are recognized.The first main factor mainly composed of Ca2+,HCO3-and total hardness,shows the influence of the leaching in calcite.The second factor,made up of K++Na+and Cl-,reflects the soluble salt in aquifers.The third main factor,composed of SO2-4 and NO3-,represents the impacts of human activities,such as the use of fertilizer and pesticide,the pollution of sewage from life.The forth main factor,pH and Mg2+,reflects the influence of the leaching in dolomite under weak alkali environment.
