| 摘 要： | 在调查取样的基础上，充分利用前人成果资料，应用SPSS及地下水污染分析软件，对莲花山地区区域地质条件、水化学参数空间分布特征、地下水化学类型、地下水化学成因进行分析研究，认为：莲花山地区地下水的硬度较高且矿化度较大；HCO3-浓度的平均值最大，在地下水的离子中占据主导地位；TDS（溶解性总固体）浓度较高且不同区域间浓度相差较大；莲花山地区部分区域偏硅酸、锶达到矿泉水标准，是矿泉水开发潜力区；研究区Na+和K+同时来自岩盐和硅酸岩的溶解；研究区浅层地下水中的Ca2+和Mg2+主要来源于碳酸盐的溶解；莲花山地区浅层地下水发生了阳离子交换作用.

| Abstract: | Based on the survey, sampling and previous data, the SPSS and other software for groundwater pollution analysis are applied to study the regional geological conditions, spatial distribution characteristics of hydrochemical parameters, chemical types and chemical genesis of groundwater in Lianhuashan area, Changchun City, Jilin Province. The results are shown as follows:The groundwater is characterized by high hardness and high salinity; The average HCO3- concentration is dominated in the ions of groundwater; The mass concentration of total dissolved solids(TDS) is high with large difference between zones; The metasilicic acid and Sr contents in parts of Lianhuashan area meet the standard of mineral water, serving as the development potential area; The Na+ and K+ both come from the dissolution of rock salt and silicate rock; The Ca2+ and Mg2+ in shallow groundwater are mainly from the dissolution of carbonate; Cation exchange has occurred in the shallow groundwater. |
