| 摘 要： | 依据新疆巴州水利管理处灌溉试验田内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、全盐、电导率及矿化度等5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HCO-3含量与总碱度关系密切,电导率主要受Na+影响,Na+与SO2-4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 experimental field of Xinjiang Bazhou water resources management division,the analysis method of relevancy analysis combining with correlation analysis is used to analyze the relations among principal chemical compositions in groundwater samples and 5 indexes,such as total hardness,total alkalinity,electrical conductivity,total salt and mineralization degree.The results indicate that the variation in total hardness is mainly subject to Mg2+ influ... |
