西北黑河下游额济纳盆地地下水系统研究(上)

The study on the groundwater flow system of Ejina basin in lower reaches of the Heihe River in Northwest China

本文从额济纳盆地含水系统结构及埋藏分布、地下水补给与排泄、地下水流场、水化学特征、水环境同位素等方面的综合分析入手 ,将全盆地划分为潜水和承压水 2大子系统 ,并进一步区分出

The groundwater flow system in Ejina basin could be divided into two systems,the phreatic water and the confined groundwater,and five subsystems.These systems and subsystems are characterized by many factors,such as aquifer structure and its distribution in three dimension,groundwater recharge and discharge,goundwater flow field,as well as groundwater chemistry and environment isotope.
