| 摘 要： | 森林火灾是一种突发性强、随机性高、扑救极为困难的自然灾害，在森林燃烧过程中可释放出高浓度PM2.5颗粒物。PM2.5是除直接烧伤和窒息外，对森林火灾扑救人员生命安全造成巨大威胁的重要污染物之一，也会给林区居民身心健康带来严重危害。文中结合国内外以森林火灾、计划烧除、室内模拟燃烧等为实验手段的森林燃烧研究，总结森林燃烧释放PM2.5的采样方法、成分分析、扩散研究、控制方法等研究进展，分析影响森林燃烧释放PM2.5的气象因素、可燃物特征、林火行为等因素，以期为提高森林火灾扑救效率、降低火灾扑救过程中的伤亡事故以及后续相关研究提供参考。

| Abstract: | Forest fire is a natural disaster which is characterized with strong burstiness, high randomness and extremely difficult to put out, and high concentration PM2.5 particles could be released from forest burning. In addition to direct burns and asphyxia, PM2.5 is one of the main pollutants which threaten the safety of forest fire fighter. This paper reviews the forest combustion research at home and abroad on forest fire, prescribed burning, and experimental simulation combustion, summarizes the research progress in the sampling method, component analysis, diffusion research and control method of PM2.5 emission from forest burning, and analysizes the influence factor such as meteorological factors, fuel characteristics and forest fire behavior, in order to provide reference to the further study of the efficiency improvement and casualties reduction in forest fire fighting. |
