摘要 森林地表死可燃物是引起森林火灾的重要原因,掌握森林地表死可燃物载量的分布,对预防火灾和可燃物管理有重要意义。依据1h、10h和100h分类标准,对呼中林区的不同林型内的地表死可燃物载量进行了对比分析。结果表明:樟子松林内死可燃物总载量最高,偃松林内的最低;对不同类型兴安落叶松林群落的地表死可燃物进行比较,发现笃斯越桔-兴安落叶松林内死可燃物总载量最高,而泥炭藓-杜香-兴安落叶松林的最低;此外,相关分析表明,兴安落叶松死可燃物总载量与平均胸径、平均树高、草本盖度、凋落物厚度呈显著的正相关,与坡向、腐殖质厚度等因子呈显著负相关;多元线性回归分析表明,用兴安落叶松林的凋落物厚度、草本盖度、平均树高因子可较好地估算地表死可燃物总载量,进而为森林可燃物的管理和指导森林防火提供科学的依据。 Forest surface dead fuel is the most important factor arousing forest fire. To understand the distribution of forest surface dead fuel load is of significance for forest fire prevention and fuel management, In this study, the forest region of Huzhong in Daxing' anling was selected as study area, and the load distribution of surface fuel in different forest types was compared based on the classification standard of 1 h, 10 h and 100 h. The results showed that the load of dead fuel was the highest in Pinus sylvestris vat. mongolica forest, and the lowest in Pinus pumila forest. The comparison of different Larix gmelinii types showed that the load of surface fuel was the highest in Vaccinium uliginosum - Larix gnwlinii forest and the lowest in Sphagnum palustre -Ledum palus- tre- Larix gmelinii forest, Correlation analysis indicated that the load of surface dead fuel had significant positive correlations with average diameter and average height of trees, herbage coverage, and litter thickness, but significant negative correlations with slope and humus thickness. Multiple linear regression analysis indicated that the factors litter thickness, herbage coverage, and average height of trees could be used to better calculate the load of surface dead fuel in Larix gnwlinii forest, which could be useful for providing scientific basis for forest dead fuel management and forest fire prevention.
