摘要：森林的燃烧过程极为复杂 ,火行为是森林可燃物燃烧的一系列现象的总和。国内外林火研究人员多年来致力于火行为特征的研究描述 ,在火场范围 (周长或面积 )、火焰特征、火强度、火头的蔓延速度等方面取得了一些显著的进展 ,其中火强度、火焰高度和火蔓延速度是林火行为的 3大指标。火行为直接受火环境的影响。
The process of forest combustion was very complex. The characters of the forest fuel were showed through fire behavior. In the world, there are a lot of researchers to study fire behavior for many years, and they have made a great progresses on some aspects, such as fire spot range (perimeter or area),flame characters, fire intensity and fire spreading. Fire intensity, flame height and fire spreading are basic characters of the fire behavior. The fire environment directly affects fire behavior.Fire behavior of forest burning was a series of reactions from catching fire, spread to weakening and dying. Fire behavior was the result of all reactions, and it was showed with the fire spreading, fire area enlarging (perimeter or area), fire intensity amplifying and other extreme forest fire behavior, such as spot fire, high intensity fire (three dimension). Fire intensity, flame height and the speed of fire spreading were main indexes of fire behavior characters. Fire behavior, flammability and number of the fire spots were also influenced by fire environment.
