摘要
通过分析华北平原地下水系统的动态特征及其含水层的分布特点 ,应用Modflow软件 ,建立了华北平原地下水系统数学模型。根据对该模型的识别分析结果 ,得出华北平原由于地下水超采 ,地下水位降低 ,增加包气带的厚度 ,从而腾出了地下水库容。据此提出充分利用含水层的地下空间 ,修建地下水库 。
Based on the analyses of the dynamic feature of groundwater and distribution,and the feature of aquifers of the Huabei plain,with applying the Modflow software,the authors build the mathematical model of groundwater system. According to the results made by the identification and analysis with the model,the authors drew the conclusion that excessive exploitation of the groundwater has greatly depressed the groundwater level,enhanced the thickness of vadosezone and vacated the storage capacity of groundwater. Therefore,the authors suggest making full of exploiting underground-space, building underground reservoir and depositing outer water resources.
