摘　　要：将虚拟现实与可视化空间分析技术应用于地下水科学管理工作可以弥补传统技术在分析研究、辅助决策中的不足,发现仍有空间数据模型、空间数据库、合适的虚拟现实方法以及高效的可视化空间分析算法等问题有待解决。结合实际研究与应用工作,探讨了地下水及其赋存地质体的空间数据建模与数据库存储技术,基于OpenGL图形库实现了地下水、地质体、相关地表信息、等水位线、地下水流向等的3维可视化,设计并实现了基于纵断面快速生成算法的可视化空间分析功能。以苏锡常地区为研究示范区,开发了"苏锡常地区地下水空间信息可视化虚拟分析系统"软件,在实际地下水科学管理工作中取得了明显效果。To resolve the problems in conventional technologies of analysis and decision supporting, the virtual reality and visual spatial analysis technology can be applied to the scientific management of ground water. There are some problems to be solved, such as spatial data model, spatial database, appropriate virtual reality method, effective algorithm of visual spatial analysis, and so on. Integrated with practical research and application works, the modeling method of ground water and geological body, the storage environment of ground water, was analyzed and discussed. Visualization of ground water, geological body, relative surface information, iso-water-level line, flow direction of ground water was realized based on OpenGL, a world famous open 3D graphic library. After that, visual spatial analysis functions based on fast vertical-section generation algorithm was designed and realized. Taking ＂Su-xi-chang＂ , a region locates in Jiangsu （a east province of China）, as a case study, we developed a suit of software named ＂Ground Water Spatial Information Visualization and Virtual Analysis System for Su-xi-chang Region＂, which is an effectire evidence in the application to scientific management of ground water.
