摘　　要：FARSITE(Fire Area Simulator)是一个基于物理学、燃烧学和试验理论为一体的时空火面积模型,它集成了地表火蔓延模型、可燃物含水率模型,飞火模型、火加速模型和树冠火蔓延等模型。FARSITE所需的空间可燃物数据和地形是由ARCVIEW GIS来生成并输入到模型中,模拟大时空尺度上的林火蔓延过程,随着时间步长的变化,模拟结果能够直观的在地图上呈现出来,随时反映出林火蔓延模拟的瞬时状态和走势。本文介绍了FARSITE模型中使用的基本原理、数据结构和模拟运行的机制以及目前国内外FARSITE模型的应用现状,以期为建立适用于我国国家级尺度的大时空尺度上林火蔓延模拟的火行为模型提供参考。FARSITE(Fire Area Simulator)is a spatio-temporal fire area model based on physics,combustion and experimental theory that integrates surface fire spread model,combustible moisture content model,flying fire model,fire acceleration model and canopy fire spread model.The spatial combustible data and terrain required by FARSITE are generated by ARCVIEW GIS and input into the model to simulate the forest fire spread process on a large spatial and temporal scale.With the change of time step,the simulation results can be visually presented on the map,reflecting the instantaneous state and trend of the forest fire spread simulation at any time.This paper introduced the basic principles,the data structure and the mechanism of simulation operation used in the FARSITE model as well as the current application status of the FARSITE model at home and abroad,in order to provide a reference for the establishment of a fire behavior model applicable to the simulation of forest fire spread on a large spatial and temporal scale at the national scale in China.
