中文摘要:

      以鄂尔多斯高原乞盖淖为例，利用地下水与湖水的动态数据研究了湖水和地下水的补排关系。结果表明，地下水与湖水的补排关系存在着高度的动态性，6—9月间地下水与湖水的水动力关系多次发生变化。本次研究的结果可以作为建立地下水与湖水耦合数学模型的基础，为预测地下水开发对鄂尔多斯高原湖泊的影响提供依据。

英文摘要:

      Ordos Plateau is an important region for energy and chemical production in China.With rapidly increasing demand of groundwater,the study of influences of groundwater mining on lakes and ecological system in Ordos plateau region becomes more significant.Hydraulic and hydrochemical data were used to research the recharge and discharge relationship between Qigai lake water and groundwater.The results show that there is a dynamic relationship between them which being variable during June and September.The study can be used to establish the coupled groundwater-lake water model and predict the influences of groundwater mining on lakes in Ordos plateau region.
