The traditional method for simulating the behaviors of forest fire is to use a single ellipse to represent all of the fire points in fire scene, which has many disadvantages, e.g., the simulated result is quite different to the real situation, and it is mainly based on 2D. As a result, the represented information is limited. In this paper, the most widely used Rothermel fire spreading model and the principal of Huygen were adopted to simulate the behaviors of forest fire in different position and wind direction, and the results were shown by pseudo-particle system in 3D, which could not only get the area of fire suffering, the direction of fire spreading and the size of fire, but also provide realistic simulation to observers. The method has been successfully applied to Zhangpu forest in Fujian Province.
传统的森林火灾行为模拟方法是用单个椭圆来表示火灾场景中的所有着火点,这种方法存在诸多缺点,例如,模拟结果与实际情况相差较大,且主要基于二维。因此,所呈现的信息有限。本文采用应用最为广泛的罗瑟梅尔火灾蔓延模型和惠更斯原理,对不同位置和风向的森林火灾行为进行模拟,并通过三维伪粒子系统展示结果,该系统不仅可以得出受灾面积、火灾蔓延方向和火灾规模,还能为观察者提供逼真的模拟效果。该方法已成功应用于福建省漳浦县的森林。
