| 摘 要： | 依据新疆某水库周边耕地地下水水样化验数据,应用灰色关联分析与相关分析相结合的方法,分析了地下水主要成分与总硬度、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Ca2+影响,水中HCO3-含量与总碱度关系密切,电导率主要受Mg2+影响,Na+、K+和与Mg2+对矿化度有较大影响.通过相关分析,发现它们之间相关性极为显著.

| Abstract: | Based on water quality testing data of groundwater samples in field around Reservoir in Xinjiang,application of the grey relation analysis method combining with correlation analysis is used to analyze the relations between principal chemical compositions in groundwater samples and 4 indexes such as total hardness,total alkalinity,electrical conductivity and mineralization degree.The analytical results indicate that the variation in total hardness is mainly subject to Ca2+ fluence;HCO3-contents are closely r... |
