摘要
本文作者在额济纳盆地进行了长达3年的研究,获得了大量盆地地下水资料和水化学、同位素分析数据,在此基础上,利用水化学和环境同位素示踪技术,结合盆地水文地质条件,对盆地深层地下水的补给来源和循环特征进行了探讨。水化学和同位素结果显示,黑河流域深层地下水补给来源具有多源性,主要为核爆前形成的“老水”,水循环缓慢。在进行流域水资源开发时,对深层地下水的利用一定要慎重。
In the course of a three-years research, large have been obtained. On the basis of the data, the groundwater have been studied using hydrochemistry quantities of information of groundwater and analysis data recharge sources and circulation characteristic of deep and isotope tracing techniques combined with regional hydrogeological condition of the basin. The result shows that the deep groundwaters in the Basin has multi-recharge resources and most are ＂old water＂ formed before nuclear bombing period. The deep groundwater near the river was mainly recharged from the Heihe River. The deep groundwater in the Gurinai area was mainly recharged by the lateral flow from the Baran Jaran Desert formed in geology time. The groundwater in the confined aquifers to the north of Juyan Lake was mainly recharged by the groundwater from the north Mongolia plateau.
