摘　　要：为更好地进行森林经营与防火管护,以闽北蒲城县4种林分特征及其林下可燃物载量为研究对象,通过采集马尾松林、毛竹林、杉木林、硬阔叶林的样地林分特征与林下可燃物负荷量和水分贮量数据,建立树高曲线,分析林下可燃物载量差异,以及地表死可燃物载量与各影响因子的相关性。结果表明,4种类型的林分特征量较接近,可用于分析林下可燃物载量差异;灌木层、草本层、腐殖质层、枯落物层4种林下结构的可燃物负荷量存在差异,且符合森林生态系统群落可燃物负荷量分布规律;4种林下结构的可燃物水分贮量与乔木树种之间关系不紧密。In order to better carry out forest management and fire protection management, the characteristics of four forest stands in Pucheng County in Northern Fujian and their understory combustible matter loading were taken as the research objects. The forest stand characteristics of the sample plots and the data of understory fuel load and water storage were established, tree height curves were established, and the differences in understory fuel load were analyzed, as well as the correlation between surface dead fuel load and various influencing factors. The results showed that the characteristics of the four types of stands were similar and could be used to analyze the difference in the understory fuel load;the four understory structures of the shrub layer, the herb layer, the humus layer and the litter layer had differences in the combustible matter load., and in line with the distribution law of fuel load in forest ecosystem community;the relationship between fuel water storage of four underforest structures and arbor species is not close.
