摘  要:
林火行为的研究与RS、GIS、GPS、林火数学模型、信息网络、数据库、计算机图形学、虚拟现实等技术密切相关,近些年来,这些技术的发展以及其集成化,使得对林火的研究从二维表达方式,再到如今的三维可视化表达,经过了一个又一个阶段。林火蔓延模拟与可视化的研究趋势是注重真实再现三维虚拟森林景观、多用户参与快速决策和网络信息服务等方面。文章以林火模型的发展、林火模拟系统的实现、以及与之相关的可视化技术的发展、林火模拟的实例几点为框架,对如今虚拟景观下林火蔓延三维可视化技术的研究状况和趋势进行了概述。

摘  要:
The study of fire behavior is closely related to the technology such as remote sensing,geographic information systems,global positioning systems,mathematical model of forest fire,distributed database,information network services,virtual reality,computer graphics,etc.These years,with the integration of that technology,the exploration of the forest fire spread model has developed stage by stage from two-dimensional expression to 3D visualization.The prospects of forest fire spreading simulation and visualization will more focus on the realistic environment,multi-user participation in decision-making,and network information services,etc.This article focused on the development of the forest fire spread mathematical model,the achievement of the forest fire spread system,and the development of computer simulation and visualization technologies related to it,and reviewed the status and trends of forest fire spread simulation development.
