摘  要:
依据11、01、00 h时滞可燃物分类标准,对丰林自然保护区不同红松林群落类型内的地表死可燃物载量进行了对比分析,并利用DCCA排序法对其与环境因子的关系进行了定量分析。结果表明:椴树红松林内地表死可燃物载量最高,枫桦红松林内地表死可燃物载量最低;DCCA排序揭示了该地区地表死可燃物载量分布与海拔、坡度、坡向、坡位、郁闭度、胸径、树高和枝下高8个地形和林分因子的关系,其中海拔、坡度、树高和枝下高是影响可燃物载量的主要因子。

摘  要:
A survey was conducted to study the loading of dead forest fuels in surface soil in different Pinus koraiensis forests,and its relationship with environmental factors was analyzed by DCCA based on the classification standard of 1,10 and 100h time-lag.Results show that the dead fuel loading in surface soil in Tilia amurensis-P.koraiensis forest is the highest,and that in Betula costate-P.koraiensis forest is the lowest.The DCCA ordination reveals the correlations between dead forest fuel loading in surface soil and elevation,slope gradient,aspect,slope position,canopy closure,diameter at breast height,tree height and branch height.The main factors affecting the spatial pattern of dead fuel loading in surface soil are elevation,slope gradient,tree height and branch height.
