摘　　要：将滑坡评价与三维可视化地理信息系统相结合,利用虚拟现实技术为滑坡的评估建立一个三维可视化平台,可以生动、直观、综合地对滑坡地质灾害进行可视化研究.在系统分析设计原理的基础上分别从数据采集和处理、三维立体模型的构建、滑坡发生过程预演、灾害各个阶段评估等方面对系统进行分析研究,为滑坡地质灾害的研究和预防工作提供了科学的依据.Combined landslide evaluation with three-dimensional visualization of Geographic Information System, the virtual reality technology was used to build a 3D visualization platform for landslide evaluation, as a whole, which made the landslide visualization re- search more vivid, intuitive and synthetie. Based on the design principle, the system was analyzed and studied separately from the as- pects of data acquisition and processing, construction of 3D model, rehearsal of the landslide process, each stages of disaster evaluation and etc. , which wotild provide a decision support basis for research and prevention of landslide disaster.
