| 摘 要： | 应用5种概率分布律对突脉青冈林5个主要树木种群的直径结构进行拟合。结果表明:除少叶黄杞对5种概率分布率全部不接受外,突脉青冈、杜英、白楠的直径分布符合威布尔分布、Γ分布、β分布(除突脉青冈)和对数正态分布,罗浮栲只符合β分布。偏度大部分呈正偏,峭度大部分为负值,说明种群直径分布范围较大,中径材占多数。

| Abstract: | The results showed that except that Engelhardtia fenzelii wasn't adapt to all 5 probability distribution rates,Elaeocarpus decipiens,and Phoebe neurahtha diameter distribution met β distribution,Weibull distribution,Γ distribution,and normal logarithmic distribution,Cyclobalanopsis elevaticostata met the last 3 ones,and Castanopsis fabri only met the first one.Most skewnesses were positive,most kurtosises were negative,which showed that diameter distribution range of population with middle-diameter timber as the most was relatively large. |
