森林燃烧中的火焰特征研究进展

阐述火焰的概念，从火焰高度与长度、火焰颜色与温度、火焰热辐射与结构、火焰传播与火焰淬熄等方面对火焰特征进行综述。可利用火焰燃烧频率判断森林火灾是否发生，利用森林可燃物燃烧的火焰颜色进行火焰区域分割、提取并进行识别。影响森林燃烧火焰的主要因素是森林可燃物，其结构与组成等特征直接决定了燃烧蔓延及火焰特征。未来将聚焦森林燃烧火焰结构识别与特征提取。森林抚育能调整林分密度，优化林分结构，调控可燃物，提高森林抵御火灾能力。

Research Review of Flame Characteristics in Forest Combustion

This paper elaborated the concept of flame, and summarized the flame characteristics from flame height and length, flame color and temperature, flame thermal radiation and structure, flame propagation and flame quenching. The frequency of flame combustion could be used to determine whether the forest fire had occurred, and the flame color of forest combustibles could be used for flame region segmentation, extraction and recognition. The main factor affecting forest combustion flames was forest combustibles, whose structure and composition directly determined the spread of combustion and flame characteristics. Identifying the structure and feature extraction of forest combustion flames will be the focus in the future. Forest tending can adjust forest density, optimize forest structure, regulate combustible materials, and improve fire resistance.
