摘　　要：为探讨林火种类、火行为等对不同森林类型可燃物负荷量空间分布的响应,围绕山东半岛昆嵛山地区主要森林类型的地表可燃物和冠层可燃物负荷量、3个地形因子(坡度、坡位与海拔)、3个林分因子(平均树高、平均胸径与郁闭度),比较不同林分不同空间层次上的可燃物负荷量等级分布特征和林火行为趋势,分析不同层次可燃物的负荷量与环境因子之间的相关性。结果表明,不同林分之间可燃物垂直分布呈显著性差异,各林分地表火形成树冠火的概率存在差异,表现为赤松-刺衫林>赤松纯林>赤松-华山松林>赤松-火炬松林>华山松纯林>火炬松纯林>赤松-麻栎林>麻栎纯林;枯落物层负荷量与郁闭度、胸径呈显著正相关,与海拔呈显著负相关;草本层和灌木层负荷量均分别与坡位、郁闭度呈显著或极显著负相关性,草本层负荷量还与树高、胸径有显著负相关关系。In order to study the effects of spatial distribution of fuel loadings on forest fire types and behaviors in the Kunyu Mountain area of Shandong Peninsula,the canopy fuels and floor fuels of the main forest types,altitude,slope,slope position,canopy density,tree height,and diameter at breast height(DBH)were selected as the research objects.The distribution characteristics of the fuel load level of different forest stands at different levels were compared.With the calculation results with BehavePlus 5 software,we analyzed the trend of different forest fire behaviors.We used SPSS18.0 software to analyze the relationship between the load and the environmental factors of different levels of the fuel.The results showed that the vertical distributions of the combustible materials in different stands were significantly different,and different stands were prone to different forest fires.The probabilities of surface fire transferring to the crown fire of different stands were different.Litter layer load was correlated with canopy density,altitude and DBH;the herb layer load was correlated with canopy density,tree height,slope position and DBH;the shrub layer load was correlated with canopy density and slope position;canopy fuel load was mainly influenced by altitude and canopy density.
