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。
Based on the 11,01,00 h dead time combustible classification criteria, the surface dead combustibles loads of different Korean pine forest community types in Fenglin Nature Reserve were compared and analyzed. The DCCA ranking method was used to analyze the relationship between them and environmental factors Quantitative analysis. The results showed that the loading of dead combustible material was the highest on the surface of Korean pine forest and the lowest was on the surface of Korean pine forest. The DCCA rankings revealed that the distribution of dead combustible material on the surface of the forest was not related to the altitude, slope, aspect, Slope position, canopy density, DBH, height of tree height and branch height, and topographic factors. The elevation, slope, tree height and branch height are the main factors affecting the load of combustible material.
