本文提出以森林类型的生物量与能量的定量方法划分森林燃烧性。对东北林区人工针叶林——红松林、樟子松林和落叶松林,进行了具体分析。指出易燃危险可燃物(表层枯枝落叶层,易燃杂草、灌木、针叶、基径小于1厘米的小枝、枯枝)的数量和能量是划分森林燃烧性的重要根据。文章还提出了影响森林可燃物的数量和能量的主要因素是地形、年龄和含水率。依据这些因子可估算各种森林类型可燃物数量和能量的具体指标。
In this paper, the forest fire burnability is defined by quantitative methods of biomass and energy of forest type. The artificial coniferous forests-korean pine, Pinus sylvestris var. Mongolica and Larix gmelinii forests in northeastern China were analyzed in detail. It is pointed out that the quantity and energy of flammable combustible dangerous combustibles (surface litter layer, flammable weeds, shrubs, needles, twigs less than 1 cm in diameter, dead branches) are the important bases for dividing forest flammability. The article also proposed that the main factors influencing the quantity and energy of forest combustibles are topography, age and water cut. Based on these factors, specific indicators of the amount and energy of various types of forest fuels can be estimated.
