Abstract: 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.
