摘　　要：根据我国森林火灾蔓延的特点,在分析了国内外主流林火蔓延模型的基础上,将元胞自动机原理与林火蔓延自身的特点相结合,着重研究了风作用系数、地形坡度调整系数等在元胞自动机中的作用形式,并引入地图代数中距离系数的概念,对原有林火蔓延速度模型进行改进,以提高模拟精度,使模拟结果更加真实地反映现实世界中林火的蔓延特点。最后采用C#语言结合ArcEngine的编程技术,以汕头市某山地DEM(数字高程模型)数据为例,动态模拟了林火蔓延的过程。The spread of forest fire has its own characteristics in China.Based on the analysis of domestic and international mainstream of forest fire spread model and combined the cellular automata principles with the characteristics of forest fires spread,this paper improves the original model of forest fires spread by focusing on the role form of cellular automata,such as wind interaction coefficient,terrain slope adjustment factor,etc.,and by introducing the concept of the distance coefficient in the Map Algebra.The improved model can improve the simulation accuracy and make the simulation results truly reflect the characteristics of the spread of forest fires in the real world.Finally,using C # language combined with ArcEngine programming techniques,and taking the DEM（digital elevation model） data of a mountain area in Shantou City,the paper simulates the dynamic process of forest fire spread.
