摘要
为了研究帽儿山地区主要乔木树种的燃烧性质,在对8个乔木树种苯-醇抽提物、木素、综纤维素及燃烧速度、绝干含水率等理化性质测定分析基础上,结合其生物学与生态学特征赋值,应用主成分分析法对其燃烧性进行了综合分析。结果表明:8个树种燃烧性大小为红皮云杉>樟子松>山杨>红松>落叶松>胡桃楸>黄波罗>水曲柳;水曲柳燃烧性最弱,抗火能力最强,适合作帽儿山地区的防火树种。
In order to investigate the flammability of the main tree species in the Maoer Mountain area,northeastern China,we investigated the physicochemical properties of eight kinds of tree species,such as benzene-alcohol extracts,lignin,holocellulose,burning rates,absolute dry moisture content.Combined with the evaluation of biological and ecological features,a principle component analysis was carried out to evaluate their flammability.The results show that the flammability order is Picea koraiensis Pinus sylvestris var.mongolica Populus davidiana Pinus koraiensis Larix gmelini Juglans mandshurica Phellodendron amurense Fraxinus mandschurica,indicating that Fraxinus mandschurica has the strongest ability to resist fire,and is one of the best tree species for fire prevention in the Maoer Mountain area.
