摘要: 利用云南松树冠部分的易燃可燃物调查取得的资料,将树冠分为3个层次,每个层次按照标准分为1时滞(<1cm)、10时滞(1~2.5cm)、100时滞(≥2.5cm)3类,分别分析不同层次与不同时滞的枝、针叶之间的关系。结果表明:云南松树冠各层的易燃可燃物的重量均随着径级的增大而增大;云南松树冠叶量的多少与火灾的发生有着很密切的联系,但是叶量多少并不能完全决定火灾发生的程度。

Abstract: Investigation was conducted on the combustibles of Pinus yunnanensis' canopy and the canopy was divided into three levels, that is 1 T-delay (<1cm), 10 T-delay (1~2.5cm) and 100 T-delay (≥2.5cm) according to the criteria. Then the relationship between different levels and different T-delay of the branches and leaves was analyzed. The results show that weight of canopy combustibles along with the diameter class increases., and the leaves are very closely related to occurance of forest fire,but can not completely determine the occurrance degree of forest fire.

Key words: Pinus yunnanensis, combustibles, diameter distribution
