摘　　要：灾情信息在GIS系统中的可视化表达是GIS系统应用于减灾应急救援工作的需求。基于灾情信息的复杂性,设计了集二维和三维结构于一体的GIS系统作为灾情信息综合表达的多维空间可视化平台,在此基础上实现了各类灾情信息的可视化表达及综合灾情信息的一体化集成显示。将该方法运用于某自然灾害减灾系统中的灾情信息可视化表达与灾情展示模块,实践结果证明了该方法的可行性与优越性。Visualization expression of disaster situation information in GIS is a requirement of application of GI5 to disaster emergency relief. Because of the complexity of disaster information, a GIS system integrated with 2D and 3 D modules was designed as a multi-dimensional spatial visualization platform of comprehensively expressing disas- ter situation information. On this basis, the visualization expression of all kinds of disaster situation information was implemented. The method was used in a disaster information visualization expression and disaster data visualization showing module of a disaster control and reduction system. The results show the feasibility and advantage of the
