| 摘 要： | 重点探讨气候变异对内蒙古呼包平原地下水资源、地下水流场和动态的影响。在介绍呼包平原水文地质条件的基础上,运用地下水模型软件PMW IN 5.1建立了研究区双层地下水流模型,并根据1998年地下水动态观测和统测资料对模型进行识别。通过对近51 a降水量的分析,确定将连续出现的2个特枯年作为地下水的变异条件,运用地下水模型对变异条件下地下水状态进行模拟,结果表明:2年间对地下水的严重超采,使地下水亏空量达75 296.34万m3,潜水和承压含水层的地下水位大幅度下降,潜水位最大下降4 m左右,承压水位最大下降17 m左右;漏斗中心主要集中在开采量大的呼和浩特和包头市区。 |

| Abstract: | The influences on groundwater resource,flow and water table change with time due to climate aberrance are focused on in Hubao Plain, Inner Mongolia,China.Based on the hydrogeologic conceptual model,a dual layers' groundwater numerical model was built up in the study area with groundwater modeling software PMWIN 5.1,and the model was calibrated by means of simulating water table curves and flow net in 1998.The two extra drought periods were defined as a groundwater aberrance condition by analyzing rainfall of recent 51 years,and the groundwater states were simulated by the model on the aberrance condition.The result shows:(1)Groundwater over-pumping in the extreme results in a groundwater storage decrease of 752.963 4×10~(6)m~(3).(2)Water tables in unconfined and confined aquifers depress in large extend.The maximum drawdown in unconfined aquifer is about 4 m,and in confined aquifer is about 17 m.The centers of drawdown are located at the downtowns of Huhehaote and Baotou,in which groundwater is extremely over-developed. |
