摘　　要：长春市内存在多个流域,随着城市化进程的不断加快,长春市地下水面临着资源紧缺及污染严重等问题,对此本文以长春市典型流域为研究区,分析研究区浅层地下水化学与水质的时空分布特征,得出结论:(1)2014年,研究区主要体现为SO_(4)·HCO_(3)-Ca·Mg型水和HCO_(3)·Cl-Ca·Mg型水;2022年,地下水类型为低矿化度的HCO_(3)·SO_(4)-Ca·Mg型水。(2)区内水化学组成主要受岩石风化作用与蒸发结晶作用控制。There are many river basins in Changchun,and with the continuous acceleration of urbanization,groundwater in Changchun is facing problems such as resource shortage and serious pollution.This paper takes typical river basins in Changchun as the research area,analyzes the spatial and temporal distribution characteristics of water chemistry and water quality of shallow groundwater in the research area,and draws conclusions:(1)In 2014,the study area was mainly embodied in SO_(4)·HCO_(3)-Ca·Mg water and HCO_(3)·Cl-Ca·Mg water;In 2022,the groundwater type will be HCO_(3)·SO_(4)-Ca·Mg water with low salinity.(2)The water chemical composition in the area is mainly controlled by rock weathering and evaporation crystallization.
