地理信息系统与地下水资源评价模型集成应用研究

Application Research on Groundwater Resource Evaluation Modal Integrated with GIS

以常州市区与武进市地区为研究区域,在对该地区孔隙地下水分布特征、水文地质条件等方面进行调查分析的基础上,构建了常武地区地下水资源评价研究的概念模型,在此基础上构建了第Ⅱ与第Ⅲ承压水流的数学模型,并将地下水资源评价模型与地理信息系统(GIS)进行有机集成,充分利用GIS的空间分析功能及其可视化表达能力,研究地下水资源评价过程中含水层空间与模拟时间的可视化离散、计算参数的可视化赋值、模型的可视化拟合及其评价结果可视化表达的方法,基本实现了地下水资源评价过程的可视化,为常州、武进地区地下水资源的科学管理提供了空间辅助决策支持.

Basing on making a study of distribution characters and hydro-geologic conditions of porous groundwater flow in Changzhou and Wujin area, the conception model, as well as the mathematic model on the 2nd and 3rd confined water was constructed. Simultaneously, groundwater resource evaluation model was integrated with GIS to make full use of spatial analysis and visual expression functions of GIS, and methods of hydrated layer spatial and simulated temporal visual discretion, visual calculation of parameters, visual fitness of model as well as visual expression of the evaluation outcome in the process of groundwater resource evaluation are also studied. Finally, the visualization of groundwater resource evaluation is basically achieved to provide the spatial decision support for the scientific management on groundwater resource in Changzhou and Wujin.
