The Properties of Groundwater Chemical Composition by Gray Relevancy Analysis in Boertala,Xinjiang

依据新疆博州地区20处地下水水样的水质化验数据,应用关联分析与相关分析相结合的分析方法,分析了地下水样中几种成分与总硬度、总碱度、电导率及矿化度4个指标之间的关系。结果表明,总硬度变化主要受Mg2+影响,水中HCO3-含量与总碱度关系密切,电导率主要受SO42-影响,SO42-与Cl-对矿化度有较大影响。通过相关分析,发现它们之间线性相关性较好。

Based on water quality testing data of groundwater samples from 20 different locations in Boertala areas of Xinjiang, the method of relevancy analysis combined with correlation analysis is used to research the relations between several chemical compositions of groundwater samples and 4 indexes which being total hardness, total alkalinity, conductivity and mineralization. The results show that the variation of total hardness is mainly inflnenced by Mg^2＋ ;HCO3^- content is closely related to total alkalinity; conductivity is mainly affected by SO4^2- ; and SO4^2- and Cl^- have the great impact upon the mineralization. A good linear relationship among them is found by the correlation analysis.
