摘 要:对枫桦红松林样地的树高、胸径、郁闭度、林龄等林分因子和坡度、坡向和坡位等立地条件因子的不同时滞地被死可燃物载量进行了分析,并构建了地被死可燃物载量与林分因子、立地条件因子的回归模型。其结果表明,利用郁闭度、坡位和平均胸径能够较好的估算枫桦红松林地被死可燃物载量。Forest litter was the main material basis of forest combustion. Controlling forest surface dead fuel loads was important significance for prevention of forest fires and fuel management. Our 30 pieces of sample of Korean pine tree height, diameter at breast height, crown density and forest age and stand factors such as slope gradient, slope direction and a factor in different site conditions, such as the delay of the surface dead fuel loads on the field investigation and indoor experimental analysis and calculation, analyses the Korean pine dead fuel distribution characteristics.Meanwhile Spss statistical software was applied, and analysis correlation of dead fuel loads, stand factor and site conditons, and regression model is established.The results showed that the use of canopy density, slope and the average diameter at breast height can better estimate dead fuel loads of Korean pine
