摘　　要：【研究目的】为查明长春新区地下水特征及演化,支撑东北老工业基地建设。【研究方法】本文在调查取样的基础上,充分利用前人成果资料,应用SPSS分析软件、地下水污染分析软件,通过对长春新区的地质条件、水化学参数空间分布特征、地下水化学类型、地下水化学成因的分析,得出系列结果。【研究结果】长春新区地下水的硬度较高且矿化度较大,HCO_(3)^(-)在地下水的离子中占据主导,Ca^(2+)、Cl^(-)、SO_(4)^(2-)、Na^(+)在地下水中的绝对质量浓度较高;pH、H_(2)SiO_(3)、Sr、TDS、Mg^(2+)、HCO_(3)^(-)的质量浓度相对稳定;地下水离子以HCO_(3)^(-)和Ca^(2+)为主;Na^(+)和K^(+)同时来自岩盐和硅酸岩的溶解;Ca^(2+)和Mg^(2+)主要来源于碳酸盐的溶解。区内地下水质量可分为四级,其中Ⅴ类水未评出。【结论】总体来看,Ⅰ类水占7.50%,Ⅱ类水占32.10%,Ⅲ类水占20.80%,Ⅳ类水占39.60%。较好以上地下水占60.4%,总体情况较好。This paper is the result of hydrogeological and environ mental survey engineering.[Objective]In order to find out the characteristics and evolution of groundwater in Changchun new area and support the construction of northeast old industrial base.[Methods]Based on the investigation and sampling,this paper makes full use of the previous achievements and data,and applies SPSS analysis software and groundwater pollution analysis software,through the analysis of the geological conditions,the spatial distribution characteristics of hydrochemical parameters,the chemical types of groundwater and the chemical causes of groundwater in Changchun new area,a series of results are obtained.[Results]The groundwater in Changchun new area has high hardness and mineralization,HCO_(3)^(-) is dominant in the ions of groundwater,and the absolute mass concentration of Ca^(2+)、Cl^(-)、SO_(4)^(2-)、Na^(+) is relatively high;the mass concentration of pH,H_(2)SiO_(3)、Sr,TDS,Mg^(2+),HCO_(3) is relatively stable;the ions of groundwater are mainly HCO_(3)^(-) and Ca^(2+);Na^(+) and K^(+) are from the dissolution of rock salt and siliceous rock;Ca^(2+) and Mg^(2+) are mainly from carbonate dissolution of salt.The quality of groundwater in the area can be divided into four grades,among which class V water is not evaluated.[Conclusions]In general,class Ⅰ water accounts for 7.50%,class Ⅱ water 32.10%,class Ⅲ water 20.80%,class Ⅳ water 39.60%.More than 60.4% of the groundwater is in good condition.
