【摘要】 依据新疆和田地区55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Cl-影响,SO42-与Cl-对矿化度有较大影响。再通过相关分析,发现它们之间线性相关性较好。更多还原

【Abstract】 Based on water quality testing data of groundwater samples from 55 different locations in Hotan areas of Xinjiang,the analysis method of relevancy analysis combining with correlation analysis is used to analyze the relations between several chemical compositions in groundwater samples and 4 indexes such as total hardness,total alkalinity,conductivity and mineralization.The analytical results indicate that the variation in total hardness is mainly subject to Mg²⁺ influence;HCO^-₃ contents are closely related to total alkalinity;conductivity is affected mainly by Cl^-;and SO^2-₄ and Cl^-have the great impact upon the mineralization.A better linear relationship among them is found via the correlation analysis.更多还原
