摘　　要：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。The chemical characteristics of groundwater are analyzed by the method of statistics based on the results of chemical properties in Yutian Oasis. The important ions which affect the groundwater-quality are selected. They are bicarbonate, sodium, potassium and chlorine. The quality of the groundwater is alkaline, slightly hard to ultra-hard. Fresh, and slight to neutral mineral water are found in the research area. There are two kinds of water in the research area which are fresh to weak mineral sodium bicarbonate water and slight to neutral mineral sodium bicarbonate water. The principal components analysis model, and the regression analysis model for Total Dissolved Solid and content of ions have been set up.
