摘　　要：为研究鲁中山区主要森林类型内易燃可燃物负荷量及其空间分布对林火种类和林火行为等的影响,以鲁中山区香山地区4种森林类型为研究对象,划分了林内易燃可燃物垂直分布层次,比较了4种森林类型同一垂直层次和不同垂直层次的易燃可燃物负荷量及分布,分析不同森林类型的林火种类、林火行为和森林火险,并根据林分总负荷量评估森林燃烧性。结果表明:油松林燃烧性最高,易引发森林火灾,形成高强度地表火和树冠火,并易发生地下火;刺槐林燃烧性最低,不易引发大的森林火灾,但可发生中强度地表火;麻栎林易发生高强度地表火,并且可发生中强度树冠火;侧柏林由于人为抚育严重,不易发生地表火,但易引发高强度、高蔓延速度的树冠火。4种林分的燃烧性大小顺序依次为:油松林>麻栎林>侧柏林>刺槐林。In order to study flammable fuel loads of the main forest types in mountainous area of Shandong Province and its spatial distribution effects on the kinds of forest fire and fire behavior and others, we took 4 types of forest stands in Mount Xiang as the research objects,and divided the vertical distribution levels of the forest flammable fuel loads,and compared the flammable fuel loads distribution of 4 kinds of forest types in the same vertical levels and different spatial levels,and analyzed different kinds of forest fire and behavior of forest fire and the forest fire danger rating of 4 types of forest stands, and assessed the forest combustibility according to the total loads of stands. The results showed that Pinus tabuliformis forest ex- hibited the highest combustion ability, prone to forest fire, and to produce high intensity surface fire and crown fire,and prone to ground fire. Roblnia pseudoacacia forest had the lowest combustion ability,not easy to cause large forest fire,but could cause medium intensity surface fire. Quercus acutissima forest was prone to high intensity surface fire, and could cause medium intensity crown fire. Platycladus orientalis forest, seriously artificial tending, was less prone to surface fire, but was prone to high intensity crown fire. The order of 4 types of forest stands combustibility was P. tabuliformis. 〉 Q. acutissima. 〉 P. orientalis. 〉 Robinia pseudoacatia.
