| 摘要: |
| 文章以云南省安宁市为例，研究和评价不同林分（纯林、混交林）、不同龄组的云南松林地表可燃物载量与林分因子之间的关系，并进行回归分析，建立数学模型。通过76个样地的林分因子测定分析，建立了云南松林地可燃物载量的四个预测模型。其中林分龄组、郁闭度因子建立的模型FL=1.4874e0.0095N，FL=3.2845M1.084，模型拟合效果较好，方程的相关系数R2分别为0.836 6，0.885 6。 |

| Abstract: |
| Stand factors of 76 Pinus yunnanensis forests stands were investigated in Anning city, Yunnan province. The relationship between fuel loading and stand factors were analysied through Regression analysis. It is showed that crown density and stand age infect the fuel loading siginificantly. Four forecast model of fuel loading of P. yunnanensis forests were established. The model of stand age group is FL=1.4874e0.0095N and the model of crown density factor is FL=3.2845M1.084 with R2 0.836 6, 0.885 6, respectively. |
