通过燃料床模拟林火蔓延过程的实验,观测不同坡度时的林火动态特征,实验结果显示,林地坡度的变化使林火蔓延过程呈现出突变形态。
Through the experiment of simulating the spread of forest fire in the fuel bed, the dynamic characteristics of forest fire at different slopes were observed. The experimental results showed that the change of forest slope showed a sudden change in the spread of forest fire.
