摘　　要：地下水的开发一直是困扰城市发展的难题,过度的、不恰当的地下水开发往往对地下水资源造成不可恢复的损害。济南地区已开发了长孝水源地开采利用岩溶水,研究这一区域适量增采条件的地下水动态响应对地下水的合理开采具有现实意义。本文建立了长清孝里铺水文地质单元数值模型,并运用Visual MODFLOW软件对模型进行计算。经过对模型进行长达3年的识别与验证,验证了模型的合理性与有效性。随后将模型用于不同开采方案下的地下水位预报和地下水动态响应分析,得出了不同开采方案对地下水影响的预测结果,根据水位预测结果显示长清地区岩溶水开采量不宜超过14万m^(3)/d。The development of groundwater has always been a difficult problem for urban development.Excessive and inappropriate groundwater development often causes irreparable damage to groundwater resources.Changxiao water source area has been developed in Ji'nan area.It is of practical significance to study dynamic response of groundwater under the conditions of appropriate increase of extraction in this area.In this paper,hydrogeological unit numerical model of Changqing—Xiaolipu has beem established,and the Visual MODFLOW software is used to calculate the model.After three years of identification and verification of the model,the rationality and effectiveness of the model are verified.Then,the model is applied to the groundwater level prediction and groundwater dynamic response analysis under different mining schemes,and the prediction results of the impact of different mining schemes on groundwater are obtained.According to water level prediction results,the exploitation amount of karst water in Changqing area should not exceed 140000 m^(3)/d.
