摘要
运用方差分析法对23个乔木树种叶子的燃烧速度进行统计,分析树种的燃烧性质,研究结果表明:燃烧速度较快的树种有糠椴(Tilia mandshurica)、红皮云杉(Picea koraiensis)、五角槭(Acer truncatum)、枫桦(Betula costata);燃烧速度较慢的有黄檗(Phellodendron amurense)、水曲柳(Fraxinus mandshurica)、家榆(Ulmus pum-ila)、黄榆(Ulmus macrocarpa)、春榆(Ulmus propinqua).燃烧速度与绝干含水率之间存在着负相关关系.燃烧速度较慢的树种,燃烧性较差,可以考虑做防火树种.
Variance analysis to study the combustibilities of these tree species including the combustion velocity of 23 species of arbora in Xiaoxing＇an Mountain of Heilongjiang Province.The results show that the combustion velocity of Tilia mandshurica,picea koraiensis,Acer truncatum,and Betula costata are fast,and the combustion velocity of Phellodendron amurense,Fraxinus mandshurica,Ulmus pumila,Ulmus macrocarpa,and Ulmus propinqua are slow.Combustion velocity has a negative relationship with absolute moisture content.The tree of lower combustion velocity has the bad flammability and can be used in the fire prevention.
