| 为了明确珠三角地区典型森林可燃物载量的分布格局, 分析影响分布格局的重要因素, 研究以
珠三角地区中山市森林为研究对象, 基于 22 个标准乔木林样地, 通过野外调查、 实验室称量测定获得不
同样地不同组分的可燃物载量, 采用单因素方差分析法分析不同组分之间可燃物载量、 单位面积可燃物载
量的差异, 采用空间插值分析可燃物载量的空间分布特征。 结果表明: (1) 乔木层是研究区森林可燃物
载量的主要组成部分, 其次是灌木层、 腐殖质层、 草本层。 单位面积可燃物载量的垂直分布与可燃物载量
一致。 细小可燃物载量以枯落物层 1 (直径<0. 6 cm 的小枝、 叶和杂草) 为主, 表明该区域森林枯落物分
解速率较高。 (2) 在空间分布上, 乔木层表现为中部低, 东部高; 灌木层为中部低, 东北、 西南高; 草
本层、 腐殖质层、 枯落物层均显示为由西北向东南降低。 这一分布格局可能与区域林分类型相关。 |

| Abstract: |
| To clarify the distribution pattern of typical forest fuel load in the Pearl River Delta region and
analyze the important factors affecting the distribution pattern, this study took the forest of Zhongshan City in the
Pearl River Delta region as the research object, based on 22 standard tree forest sample plots, obtained the fuel
load of different components through field investigation and laboratory weighing. Single-factor ANOVA was
used to analyze the difference between fuel load and fuel load per unit area among different components, and
spatial interpolation was used to analyze the spatial distribution characteristics of fuel load. The results showed
that: (1) Thetree layer was the main component of forest fuel load in the study area, followed by shrub layer,
humus layer, and herb layer. The vertical distribution of fuel capacity per unit area is consistent with the fuel capacity. The small fuel load is dominated by litter layer 1, which indicates that the decomposition rate of forest
litter in this area is higher. (2) In spatial distribution, the tree layer is lower in the middle and higher in the
east. The shrub layer is low in the middle and high in the northeast and southwest. The herbaceous layer, humus layer, and litter layer are shown to decrease from northwest to southeast. This distribution pattern may be
related to regional stand types. |
