摘要: 地表枯死可燃物负荷量多少是森林火灾发生的基础。调查八达岭林场不同地形条件下油松林地表枯死可燃物和林分因子,取得42块样地资料;用线性相关分析法对各因子与地表枯死可燃物负荷量进行分析,平均树高、坡度和海拔与对应负荷量有显著线性关系;应用多元线性回归中的逐步回归剔除法,建立了估测模型,除平均胸径外,平均树高、密度、郁闭度、海拔、坡度被引入,经检验回归显著,该估测模型可用于其它油松林地表可燃物负荷量估测。

Abstract: The amount of dead surface fuel loading is the main basic cause that forest fire occurs.42 plots of Pinus tabulaeformis forest were surveyed,including landform factors, stand factors and several types of specific forest fuel. The correlative relations among the loading and the effective factorswere analyzed through correlation analysis method.The result shows mean standheight, slope gradient, and altitude are linear correlative with fuel loading, but mean DBH, shade coverage and stand density are not.The predicting models between fuel loading and several factors are set up by linear regression analysis method. The factors except mean DBH are used in the models.The test effect is remarkable, and the predicting models are convenient to other Pinus tabulaeformisforest fuel loading calculation.

Key words: fuel loading, Pinus tabulaeformis forest, stand and landform factors, correlation analysis method, linear regression analysis method
