On the base of analysis of hydrologic geology from aquifer distribution , boundary conditions and dynamic characters etc . in the research area , the paper sums up the hydrologic geologic condition , builds up the conceptual model of groundwater resource evaluation and presents 2d calculation model , as well as numeric solution and computing flow chart . after introducing general solutions of mathematic models and implementation method of rectangular grid , the paper realizes the automatic technique of spatial dispersion rectangular grid of evaluation models based on gis . finally , the paper fulfills the integration of gis with groundwater resource evaluation models from gis - based basic management information , spatio - temporal dispersion of models , definition of subprogram and visual evaluation of parameters , as well as models simulation etc . , and visualizes the results of evaluation models 论文以地下水超采?地下水降落漏斗?地面沉降现象较为严重的常州、武进地区作为研究评价区域,在对评价区域的含水层分布、边界条件和动态特征等水文地质条件分析的基础上,概化了其水文地质条件,构建了相应的地下水资源评价概念模型与数学模型,并给出其数值解法和相应的计算流程;论文在介绍数学模型的两种常用数值解法和模型空间离散的矩形网格生成技术的基础上,实现了基于gis的评价模型空间离散矩形网格的自动生成;最后,论文从基于gis的评价模型基本信息管理、模型空间时间离散方法、子程序包与模型计算参数可视化赋值、模型的拟合等方面实现了gis与评价区域的地下水资源评价模型的集成,并将模型评价结果可视化。
