中文摘要：

以三江平原挠力河流域地下水为研究对象,首先根据挠力河流域的地质岩性、水位变动带、地形地貌、行政单元等将挠力河流域划分为4个区,然后分析给出挠力河流域地下水的补给量和排泄量计算方法,并采用该方法计算挠力河流域地下水的补给量和排泄量,最后对挠力河流域进行地下水均衡分析。

英文摘要：

This article is mainly based on the Sanjiang plain Naoli river Basin groundwater to study.Firstly,Naoli river basin is divided into 4 areas,according to its geological lithology,water level variation belt,topography,administrative units and so on,and gives calculation method of Naoli river basin groundwater recharge volume and discharge volume,then using this method to calculate the recharge volume and discharge volume of Naoli river basin groundwater,finally,this paper carries out the Naoli river basin groundwater balance analysis.
