摘要: 为了研究林火蔓延的动态预测及可视化模拟问题,该文在分析现有林火蔓延模型的基础上,提出选用三维曲面元胞自动机进行林火建模和蔓延模拟.该文初步完成了一个整合数字高程模型、气象因子、树种因子的三维曲面元胞自动机模型,设计了数据提取、加工、应用框架,开发出了能够进行林火蔓延三维模拟的软件系统.并通过八达岭林场局部地区的模拟,指出了应用该模型,可以实现不同条件下的林火蔓延模拟,快速预测林火发展趋势,同时探讨了模型改进的方向

Abstract: In order to study the forecast and simulation visualization of forest fire spread, the authors introduced Cellular Automata (CA) to forest fire modelling and spread simulation based on the existing forest fire spread models. A 3D-surface CA model was built, integrated with Digital Elevation Model(DEM), weather and tree species information. A framework was designed for data log, processing and application. A software system was developed to simulate forest fire in 3D space. It showed that the model could simulate forest fire under different conditions and rapidly predict a developing fire. Some perspectives in improving the model are also discussed.
