摘　　要：在对森林火灾进行能量和质量守恒分析的基础上,把尖点突变模型应用于森林火灾蔓延的预测,使突变理论在 森林火灾的模型中从理论上有了初步的应用。文中计算了林火发生突变时的一些分歧点,分析了林火突变的特点和变化规 律。The catatrophe theory was applied to the forest fire model, and the conservation of energy and mass of it was analyzed, the catatrophe has an elementary application in the forest fire model. The bifurcations of the forest fire model were gained based on the calculation and analysis of the factors influence to the forest fire. The spread disciplinarian and the characteristic of the forest fire were analyzed.
