森林火灾作为燃烧系统,和森林可燃物的数量,含水量以及分布状态有关,也和当时的蔓延速度和可燃物的燃烧速率有关。按照不同的要素,包括初始燃烧速率,蔓延速度和地表杂草枯枝落叶层单位面积上的负荷量,以确定林火强度。火爬坡时,蔓延速度增加,火强度相应地增加;相反,下坡火的蔓延速度减缓,火强度也相应地变小。根据计算结果,林火强度不超过1×10~3千瓦/米~2是低强度,这时1立方米内的可燃物被烧掉的数量不超过3公斤,地表杂草枯枝落叶层的可燃物数量(W_0)不超过2.5公斤。即便地表可燃物保持在2.5公斤以下,蔓延速度大于3米/分时,火强度均将超过1×10~3千瓦/米~2。地被物数量大,火蔓延速度也大的林型中将产生最大的火强度,这和过去的经验是完全符合的。

High in relief, Changbai Mountain is possessed a marked vertical distribution of climates, soils, fauna and flora. Amidst the fir and spruce belt at Dayuanyangdi, located 1400-1600 meters above sea level in Changbai Mountains, lies a certain area of meadow vegetation, of which the composition varies different altitude. Observations show although the small reed (Deyenxia angustifolia) is tha major constuctive species, the companian species, as well as the density and cover degree are different. Fire weed (Epilobinm angustifolium) , an indicator plant after forest fire, is found everywhere in the area and some reminants of burnt trees were found at the highest spot of the meadow. This shows that the plateau meadow is a secondary community. Therefore, its effective use must be coincided with its ecological characteristics, productivity and transport conditions.

长白山地势高峻,气候、土壤、动植物都有明显的垂直带性。在云冷杉针叶带林间,分布着一定面积的草甸植被,因受海拔高度影响,草甸植被成分,牧草的产量和质量都有一定的差异。为发展山区畜牧业,开发饲料资源,我们于1982年8月对该类型草甸的抚松县大鸳鸯地进行了初步考察,提出开发利用的意见。 大鸳鸯地是我们从航片中查到云冷杉针叶林带间面积最大草甸。海拔1400—1608m,植被虽然都以小叶章为建群种,但不同的海拔高度分布着不同的伴生种,草群密度、盖度等也都因高度不同而异。草甸上到处可见柳兰这种火烧后的指示植物,并在草甸海拔最高处的边缘有火烧后的树木残体。据此,我们推断该草甸是森林被烧后演替而成。同时,我们对该草甸生产力等进行了测试,并据草甸生态特性和交通条件,更合理的利用资源,提出了开发草甸建议。
