摘　　要：通过在襄城县五里堡水源地建立三维非稳定流模型,采用有限差分,交替向隐式差分等方法进行求解,采用Modflow软件模拟分析,并按照设计开采条件对该区地下水的水位进行了预测、反演。根据近十年观测数据的反演结果对比,反演结果反证了研究区地下水在设计开采量条件下水资源量是有保障的。研究结果为类似工程水源地地下水定量评价和准确计算探索了方法,同时也为其它水源地地下水的定量评价和计算提供了经验。A three-dimensional unsteady flow model is established in Wulibao water source area of Xiangcheng County,and solved by finite difference method and alternating implicit difference method.Modflow software is used for simulation analysis,and groundwater level in this area is predicted and inverted according to the design exploitation conditions.According to the comparison of the inversion results of the observed data in the past ten years,the inversion results prove that the groundwater resources in the study area are guaranteed under the condition of the designed groundwater exploitation.This paper explores a method for the quantitative evaluation and accurate calculation of groundwater in similar engineering water sources,and also provides experience for the quantitative evaluation and calculation of groundwater in other water sources.
