| 摘 要： | 王正非林火蔓延模型是目前国内比较先进的森林火灾蔓延模型,但是由于林火行为的复杂性,此模型在准确率和普适性方面仍存在许多不足。本文结合已有的成果进一步改进王正非模型,增加了可燃物湿度对林火蔓延速度的影响,改进了林火初始速度的计算方式。针对各种坡度对林火蔓延行为的影响给出了一个计算公式。与改进前相比,改进后的模型使其对林火蔓延情况的预估更为精准。

| Abstract: | Currently,the Wang Zhengfei forest fire spread model is the first forest fire spread model in China,but due to the complexity of forest fire behavior,this model still has many shortcomings in accuracy and universality.This paper will further improve the Wang Zhengfei model with the existing results,increase the influence of combustible moisture on the spread speed of forest fire,and improve the calculation method of initial fire speed.A calculation formula is given for the influence of various slopes on the spread behavior of forest fires.Compared with before the improvement,the improved model makes it more accurate to estimate the spread of forest fire. |

| Keywords: | combustible humidity initial spread speed slope forest fire spread speed model |
