【摘要】 本文介绍了基于MIS和GIS的国内外地下水数值模拟模型的发展。以北京市为研究区,在分析研究区自然地理、水文地质和应用需求基础上,提出采用浏览器/服务器(B/S)与客户机/服务器(C/S)体系结构相结合的方式,建设地下水基础信息库,将研究区概化为非均质各向同性三维非稳定地下水流系统;提出采用"稳定+相对静态+动态"的思路,找到信息系统与地下水流模型输入文件之间的数据接口,通过建立MODFLOW程序的输入文件建立水流数值模型,实现将地下水流模型与信息系统集成,探索地下水数值模拟一体化平台建设和应用。更多还原

【Abstract】 The current status and development of the integrated groundwater model and information system based on geographic information system(GIS) were introduced.Base on the physical geographic,geological and hydrogeological conditions in the Beijing Plain,and by analyzing the function and data demand,the structure combined Browse/Server(B/S) with Client/Server(C/S) was applied for integrating groundwater model and information system.The groundwater basic database was built.The study area was recognized as three-dimensional transient flow system with heterogeneous and isotropic material.Both the idea of "steady + comparatively static state + dynamic state" and the method of data connection between information system and input files of MODFLOW2000 were applied to the modeling system.Numerical model of groundwater flow was therefore developed through the MODFLOW module with established input data connection,which was formed into the dynamic groundwater modeling system.更多还原
