摘要
通过野外调查,基于森林亚类型,以主要伴生树种或下层植被为基础,对思茅松林内可燃物进行划分,并在林内进行试验火烧,得到相应的火行为参数.结果表明,思茅松林的火行为强度比较弱,主要为中低强度的火,这与林内的可燃物有关,也和所处的生境和立地条件有关;火烧后的树木死亡率比较低,表明思茅松在长期的演替中已经适应了火烧.
Through field surveys,based on forest sub-types,mainly associated species and lower vegetation,combustible material types can be classified within Pinus kesiya forest.Fire behaviors index was induced from burning experiment.Results showed that the fire behavior intensity of Pinus kesiya was relatively weak,mainly in low-intensity fire,which was due to forest combustible material,habitat and the site conditions;Trees death rate was relatively low after fire,indicating Pinus kesiya have been adapted to fire in long-term succession.
