林火蔓延模拟的研究进展

Research progress of forest fire spreading simulation

随着计算机在火蔓延模拟方面广泛的应用,出现了很多计算机仿真模型。这些模型是在原有火蔓延模型的基础上结合各种蔓延算法发展起来的,相对于原始的火蔓延模型来说,这些模型的使用范围更加的广泛,模拟的结果更加的接近真实结果。近年来数学方法在火蔓延模型中的应用也越来越多,如CA、渗透理论、突变理论和人工神经网络等等,本研究在Andrew等人研究的基础上总结了数学方法在我国林火蔓延中的一些应用。重点分析了火蔓延的影响因子,我国对可燃物模型研究的较少,在模拟过程中多是借鉴国外模型或是应用简单的可燃物代替复杂的可燃物研究,本研究指出了建立可燃物模型、气象模型的重要性和必要性。

With the wide application of computer technology in the simulation of flame spread, there have been many computer simulation models of forest fire spreading simulation, comparative to the original fire spread models, the computer simulation models were widely used and the results are closer to the real results. In recent years, the applications of mathematical methods in forest fire spreading model have become more and more, for example, CA, penetration theory, catastrophe theory and artificial neural net etc.. Based on the results studied by Andrew etc., the applications of mathematical methods in forest fire spreading model in China were summarized. The impact factors of forest fire spreading were emphatically analyzed. The importance and necessity of establishing forest fuel model and meteorological model were put forward.
