| 摘 要： | 设立64块标准地,应用回归分析,建立马尾松(Pinus massonianaLamb)林分地表可燃物载量与主要林分因子动态关系的数学模型。检验结果表明,林分因子对马尾松林分地表可燃物载量变化有极显著的影响,林分郁闭度主要影响地表1h时滞可燃物载量变化,林分平均年龄主要影响地表10 h时滞可燃物载量的变化。在实际中拟合效果良好,可用于预测马尾松人工林地表可燃物载量的动态规律,为地表可燃物管理提供科学的依据。

| Abstract: | Based on the data collected from 64 sample plots on the Pinus massoniana plantation,the regression analysis was applied,and the mathematical models of development correlation between the surface fuel loading and the stand factor dynamics was established in this paper.The results showed that the effect of all stand factors on the surface fuel loading was outstanding,but the close canopy mainly affected the 1-h time tag surface fuel loading,and stand average age mainly affected 10-h time tag surface fuel loading.It could be used to forecast dynamic regular of the surface fuel loadings of Pinus massoniana plantation and to provide scientific fundamentals for the management of surface fuel. |
