根据于田绿洲地下水水质分析结果,应用统计分析方法分析地下水化学特征,提取出对水质影响较大的离子为HCO-3、Na++K+和Cl-;地下水水质为碱性、弱硬水-极硬水,淡水、弱矿化水和中等矿化水在研究区内均有分布;研究区的地下水可划分为淡-弱矿化的HCO3-Na型水和弱-中等矿化的HCO3-Na型水两种类型;建立了地下水的主成分分析模型和总溶解固体与离子含量的回归模型。
According to the results of groundwater quality analysis in Yutian Oasis, the chemical characteristics of groundwater were analyzed by statistical analysis method, and the ions with high influence on water quality were extracted as HCO-3, Na ++ K + and Cl-. The groundwater quality was alkaline and weakly hard water Hard water, freshwater, weak mineralized water and medium mineralized water are all distributed in the study area. Groundwater in the study area can be divided into light-weakly mineralized HCO3-Na type water and weak-moderately mineralized HCO3-Na type Water two types; established a principal component analysis model of groundwater and total dissolved solids and ion content of the regression model.
