中文摘要 森林火灾按其燃烧物和燃烧部位的不同,通常可分为地表火、树冠火和地下火3种。树冠火是指在林冠层燃烧和蔓延的火,通常与地表火同时发生。树冠火发生数量不多,但其燃烧温度高、火强度大、蔓延速度快,对森林的破坏性极大。从树冠火的发生机制、蔓延模型、扑救方法、预防和减弱树冠火发生及蔓延危险性的措施几方面对当前国内外树冠火的研究进展进行了综述,并对今后的研究方向进行了展望。

英文摘要 In light of the fuels and fuel layers burned,forest fires can be divided into surface fire,crown fire and ground fire.Crown fire is the fire that burns and spreads through the crown or canopy,usually occuring simultanously with surface fire.Crown fire seldom occurs.But with high-temperature combustion,high fire intensity and fast spread,crown fire always bring great destruction to forest.The research progress at home and abroad on the occurrence mechanism of crown fire,spread model,suppression methods and measures to prevent and mitigate crown fire occurrence and spread was reviewed in the paper.Finally,research directions in the future were looked forward.
