对经典的自组织临界性森林火灾模型进行了数值模拟,在此基础上,重点对我国1960,1970,1980和1987年前后,以及日本1995年前后的森林火灾发生情况进行了比较,分析了大规模森林火灾的发生频率与中小型森林火灾之间的联系。结果表明森林火灾模型可以描述森林火灾系统的自组织临界性,并与真实的森林火灾数据符合得较好。森林火灾系统的自组织临界性对火灾防治有一定的指导作用。 Based on the numerical simulation of the classic self-organized critical forest fire model, the author mainly compared the occurrence of forest fire around 1960, 1970, 1980, 1987 and before and after Japan in 1995, Scale The relationship between the frequency of forest fires and small and medium-sized forest fires. The results show that the forest fire model can describe the self-organized criticality of forest fire system and is in good agreement with the real forest fire data. The self-organized criticality of forest fire system has a certain guiding role in fire prevention and control.
