为了研究林火蔓延的动态模拟问题，结合元胞自动机原理，对现有的林火蔓延数学模型进行改进，提出一种新的模拟林火蔓延模型。该模型充分表达了可燃物类型、温度、湿度、坡度、风速和风向等林火蔓延影响因子在元胞空间中的作用形式，通过求解出燃烧元胞向摩尔（Moore）型邻域中八个方向元胞的林火蔓延速度，来确定元胞状态演变规则函数。最后，利用地理信息系统二次开发技术将该模型表达成计算机算法，实现了不同条件下的林火行为的仿真模拟。

This study integrates the existed mathematical model and cellular automata to develop a new fire behavior model. The developed model expresses the main factors performing in the cellular space, such as forest fuel, temperature, humidity, slope, wind speed and direction, etc. And in this model the expressions of the rate of fire spread to eight neighboring cells in the Moore neighborhood are deduced, so the rules that update the cells in the lattice are proposed. Finally, the proposed model is expressed as computer algorithm by using secondary development technology of geographic information system, to realize fire behavior simulations which are under the different conditions.
