林火行为蔓延模型研究进展

森林火行为特征是进行林火预防和林火扑救的主要参考依据之一，林火行为研究在森林防火中具有重要意义。其中，林火蔓延作为关键的林火行为特征因子，林火蔓延模拟模型的构建研究一直是国内外的研究热点。文中将国内外各主要林火蔓延模拟模型按照模拟维度分为一维的传统模型和二维的空间模拟模型，总结了不同构建方法下传统模型的应用特点以及空间模拟模型的构成方法和选择；介绍了目前美国、加拿大、澳大利亚等林火管理发达国家主流的林火空间模拟系统的关键技术要点和适用条件；结合我国实际情况提出了相关研究应用建议，以期为发展我国自己的林火蔓延空间模拟模型提供参考。

A Review of Wildland Fire Spread Modelling

Forest fire behaviors is one of important reference indicators for wildland fire prevention and suppression, and therefore the study of fire behaviors is of important significance for forest fire control. The modeling of forest fire spread as the key factor to fire behaviors has been the hot study field at national and international levels. This paper divided the main fire spread simulation model into the tradition one-dimensional models to the current two-dimensional spatial simulation models based on the simulation dimensions, summarized the application characteristics of the traditional models constructed with various methods, and concluded the construction methods and selection of spatial simulation model. It also introduced the key technology and applicable condition of fire spatial simulation models used in the USA, Canada and Australian, and put forward the suggestions for modeling research and application in China with the eyes on the actual situation here. The aim is to provide references for China to develop its own forest fire spread spatial simulation model.
