【摘要】 为了研究林火行为对林火决策的重要性和林火的时空特性,主要利用渗透理论建立森林火灾的蔓延模型,通过该模型来模拟森林火灾的动向,仿真森林树木的分布情况和林火蔓延情况。仿真实验结果表明,提出的模型初步反映了森林火灾随林木分布密度不同而呈现不同蔓延情况的规律。同时,对风速、风向、地形等其他因素对火灾蔓延的影响进行了分析,并简单介绍了森林火灾蔓延的改进模型。更多还原

【Abstract】 In order to know the importance of forest fire behavior to the decision making of forest fire fight-ing,a forest fire spreading model based on the percolation theory was established to simulate the forest dis-tribution,the spread and movement of forest fire.The simulation experimental results indicated that the proposed model reflected the relationship between the forest fire spread characteristic and the forest density.Furthermore,we discussed other factors affecting the forest fire spreading,such as wind speed,wind di-rection,topography,and put forwards one modified model for forest fire spreading.更多还原
