| 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. |
