摘　　要：本文利用地下水数值模拟系统（GMS），建立了能反映海河流域平原区地下水含水层结构及其水流特性的大区域水文地质概念模型和地下水流模型，重点研究了在无开采井条件下地下水开采强度时空分布的特征，模拟了平原区1965—2005年41年阀的地下水流场及漏斗的演变过程，综合分析了海河流域平原区浅层含水层长期开采条件下地下水系统的演变过程以及地下水开采带来的影响。同时，对所建立的地下水数值模型就流场、漏斗变化以及水文地质参数等多方面进行了识别和验证。采用经过率定和验证的模型，预测分析了水资源配置制定的地下水限采方案，为南水北调实施后对海河流域地下水的修复作用以及其它可能的影响提供了可靠的分析手段和措施。The objective this study is to make the conceptual hydrogeologic model that can represents the structure and characteristics of shallow groundwater aquifers in the plain area of Hai river basin and a groundwater flow model have been constructed, using Groundwater Modeling System （GMS）. The problem on spatio-temporal distribution of groundwater exploitation intensity without detailed wells has been primarily studied. The changes on groundwater level and cone depression have been modeled from the period year 1965 to year 2005. The evolutive process of shallow groundwater system under the condition of long-term exploitation as well as the impact on groundwater level changes induced by groundwater exploitation have also been comprehensively analyzed. Meanwhile, some productions such as groundwater flow, cone depression changes and hydrogeological parameters obtained by groundwater model were calibrated and verified as well. The predictions on modeling restrained exploitation planning using the calibrated and verified model will be helpful for governor to develop strategies to conserve groundwater in the plain area of Hai river basin and improve regional water planning with the implementation of South-North Water Transfer Project.
