摘　　要：为了进一步查明长春新区水文地质条件,掌握地下水动态规律,选取饮马河流域长春新区开展研究.利用2016~2018年地下水观测数据,通过地下水动态分析、衬度系数方差分析、相关性分析,认为长春新区地下水动态特征主要为入渗-蒸发型及入渗-开采型,地下水主要接受降水补给,水位埋深受降雨和人为开采的双重影响;地下水水位埋深具有明显的空间分异特征;地下水埋深与降水量呈明显的负相关,地下水埋深与降水量的相关具有差异性.To further identify the hydrogeological conditions and find the dynamic rule of groundwater of the Changchun New District in Yinma River Basin,the dynamic analysis,contrast coefficient variance analysis and correlation analysis are conducted on the basis of observation data of groundwater during 2016-2018.It is considered that the dynamic characteristics of groundwater are mainly infiltration-evaporation type and infiltration-exploitation type.Groundwater is mainly replenished by precipitation.The water level is affected by both rainfall and mining,with obvious spatial variation.There are notable yet different negative correlations between the groundwater depth and precipitation.
