摘　　要：地下水作为邯郸东部平原主要供水水源,现已严重超采,为此采用Visual MODFLOW数值模拟模型,结合当地用水规划和地下水压采方案,建立了维持现状开采与规划开采等多种开采情境下的地下水位动态预测模型,分析了浅层地下水和深层地下水开采量与地下水位的各自对应关系,利用多元回归方法建立地下水开采量与地下水水位的相关方程。通过对比可知,规划开采情景下的平均水位普遍高于维持现状开采情景下的平均水位,肥乡、馆陶、临漳和魏县的浅层地下水位均高出3.0m以上,魏县的深层地下水位高出4.1m。Groundwater,as the main water resources for the Eastern plain of Handan,has been seriously overexploited.In this study,the Visual MODFLOW software was used to set up the numerical simulation model,which can also calculate the groundwater level in the prediction models,with two schemes to pumping groundwater in the coming years:planned mining scenario and current mining scenario.Then the relationship between groundwater exploitation and groundwater level is analyzed.The multivariate regression method is used to establish the equation of the groundwater level and groundwater exploitation quantity.By comparison,the average groundwater level under planned mining scenario is generally higher than that under current mining scenario.The shallow groundwater level are all higher than 3.0 m,such as Feixiang,Guantao,Linzhang and Weixian.The deep groundwater level in Weixian is higher than 4.1 m.
