抚顺县主要林型及地被可燃物载量的研究

森林地被可燃物是引起森林火灾的重要因素之一,为了预测预报林火发生规律、林火行为和森林火险,以抚顺县8种主要林型为研究对象,对其林内不同类型地被可燃物载量做相关分析,并研究载荷量与林分密度、林龄、坡位等因子的关系,结果表明:地被可燃物载量随林分密度和林龄增加而增大;地被可燃物载量与坡位关系密切,一般下坡载量最大,上坡载量最小。

Main forest types in Fushun County and its combustible load in ground surface

Forest combustible is one of the important factors causing forest fire. In order to forecast the rule of forest fire occurrence, forest fire behavior and forest fire danger, combustible load in ground surface was investigated in 8 main forest types of Fushun County, and the relationships between combustible load and stand density, stand age and slop position were analyzed. The results indicated that combustible load increased with stand density and forest age;The forest combustible load in ground surface was closely related to the slope position. Generally, forest combustible load is larger in the lower slope and smaller in the upper slope.
