中文摘要: |
森林火灾是危害森林的一大主要自然灾害 ,实践证明采用防火林带可以有效地控制森林火灾的发生。本文对南方的木荷、火力楠、杨梅等 11种常绿阔叶树种和杉木、马尾松两种针叶树种的叶、小枝和皮的燃烧性能及其组成成分进行了测定 ,结果表明 ,( 1)各树种均以叶的抗火性能最差 ,阔叶树种比针叶树种的抗火性能强 ;( 2 )含水量、苯 -乙醇抽取物、木质素含量和灰尘分含量是影响叶的抗火能力的主要指标. |
英文摘要: |
Fire is the primary one of the facts of deforestation. Although in recent years the level of forest management and technique of fire suppression have been improving, fire fighting force has been strengthened, the area of fire is not apparently decreased. Using biological fire resistant technique can effectively prevent the campaign fire. In this paper, fire resistant ability and component about 12 tree species, in mountain area of Daguishan, Guangxi Zhuang autonomous region, have been analyzed in laboratory. The results from this study indicated as the followings: (1) For all the tree species, fire resistant ability of leaf is more susceptible than that of branches and bark, and the broadleaf tree species are stronger than coniferous tree species in fire-resistant. (2) Calorific value, water content, combustion temperature and ash content are main indexes to affect fire resistantivity. Heat value relates to lignin content and benzene-ethanol extractive content linearly. |
