摘　　要：自上世纪60年代后期至今,海河流域平原区通过超采地下水,以牺牲水文地质环境为代价,获得了40多年经济社会的迅猛发展。以此模式推算,至2080年本地区浅层淡水含水层将被疏干。加速恶化的水文地质环境,成为制约该地区经济持续发展的瓶颈。保护地下水资源,使之可持续开发利用,成为当前的紧迫任务。应用现代信息技术分析大量的、复杂的水文地质勘探资料,进而建立仿真地层模型,是准确评价和科学管理地下水资源非常重要的基础工作。然而由于大尺度流域面积辽阔,含水层的埋深、岩性和大小规模在区域上的差异很大,因此建设大流域的地层模型,一直是国内流域机构地下水研究和管理的难点之一。本文叙述了应用GMS、SURPARC、ACCESS软件建立海河流域平原区浅层地层模型的方法和过程。该研究方法具有创新性、实用性强,可供大区域地层结构研究和地下水资源管理参考。最后,本文对建立模型应注意的问题进行了总结。Since the late 1960s, rapid economical and social development have been made in the Haihe River Basin for 40 years, by excessive extraction of groundwater and the expense of the hydrogeology environment. The shallow freshwater aquifer will be re- duced to die in 2080 according to this mode in the region. The hydrogeologic environment will become more and more deteriorat- ed, which is restricting the regional sustainable economical development. Therefore, protection of groundwater resources for the sus- tainable development and utilization has become an urgent task at present. Application of modem information technology can ana- lyze large amounts of complex hydrogeologic data and establish the stratum model, which is a very important foundation work to evaluate and manage groundwater resources. However, the depth, lithology and size of the aquifer have a great difference in the different regions due to the vast area of large-scale watershed. Therefore, building stratum model in the large-scale watershed has been domestic problem on groundwater management and research for watershed institutions. This paper described the methods and processes of the established shallow stratum model for the Haihe River Basin by using the software such as ACCESS, SURPARC, GMS. This method is innovative and practical for the reference to large regional stratigraphy structure and groundwater resources management. Finally, this paper made a summary for the process of the model established.
