【摘要】 选择井冈山自然保护区内16个树种,对其树叶的含水率、燃点、热值、粗灰分、粗脂肪、木质素、粗纤维、燃烧时间及火烧强度这9种理化性状进行了测定分析,应用因子分析法进行统计分析。通过计算和分析,得出了反映树叶抗火性的排序,苦槠、青冈、钩栲等抗火性较强,对于井冈山防火树种的选择有参考作用。更多还原

【Abstract】 Leaves of sixteen species from JingGangshan Nature Reserve were collected for analysis of their physical and chemical properties.The moisture content,ignite temperature,energy content,ash content,crude fat content,lignin content,crude fiber content,burning time,and burning intensity,were chosen as the evaluation indexes,and the nine factors were analysed.Through calculation and analysis,the order of fire resistance of the sixteen species was obtained.The species of strongest fire-resistance are Castanopsis sclerophylla,Cyclobalanopsis glauca(Thunberg) Oersted,Castanopsis tibetana Hance,etc.The result provides reference for the selection of fire-resistant tree species in JingGangshan.更多还原
