摘　　要：对实现洪水淹没场景模拟的三维可视化方法进行研究,以东平湖的洪水淹没演进为例,以Arc-GIS9.0为开发平台,利用ArcGIS的3D扩展模块,在ArcScene中由地形图构建东平湖的数字高程模型(DEM),使用ArcScene实现了各个时刻东平湖的洪水淹没演进过程和周边场景的动态模拟.该方法所有操作都在ArcGIS中进行,自动化程度高,方便,快捷;同时在研究洪水淹没分析方面,具有一定的借鉴意义.The paper carries out 3D visual study about simulation of flood evolution. Using Dongping Lake＇ s water drowning evolution for the example and taking ArcGIS9.0 as developing terrace, 3D of ArcGIS as extend model, this study makes structure of DEM with terrain map in ArcScene through which the submerged process and surroundings at Dongping Lake are sucessfully simulated. The method of operation is conducted in ArcGIS, a high degree of automation, convenient and fast; At the same time, in the study of the flood analysis, it also has certain reference significance.
