摘　　要：该文介绍了面向 2 1世纪的数字化工程中的数字流域、虚拟现实等重要概念。研究了虚拟现实技术应用于数字流域研发的相关技术 :提高图形系统效率的多种细节层次的视景表示、多层次数据管理与视景调度技术 ,优化界面的多维人机交互技术 ,流域模型构建以及 3S数据在数字流域中的应用模型。讨论了数字流域采用虚拟现实技术在三维漫游 ,仿真结果叠加 ,抗洪减灾 。Introduced the concepts of Digital Valley and Virtual Reality in the digital engineering in the 21st century. Researched many pivotal technologies of Virtual Reality which were used to build the Digital Valley: the technology of LOD and LADBMS to improve the efficiency of the graphical system, the technology of multi-dimension human-computer interaction to build friendly interface between the system and users, the model of the valley and the application of 3S data in the digital valley. Discussed the ways the Virtual Reality apply to Digital Valley: 3D browsing, adding the results of simulation, fighting flood, encouraging travel in the valley and so on.
