摘  要：
对金沟岭林场阔叶红松过伐林直径结构、重要值、分布格局以及存活曲线进行了分析。结果表明:①林分直径结构呈反"J"型,表现出了异龄林的特征,经不同分布函数拟合结果显示,对数函数、逆函数、二次函数、三次函数、复合函数、幂函数、生长函数、指数函数、逻辑函数都符合直径分布规律,R2>0.922、显著性水平P≈0,其中逆函数和三次函数的R2达到了0.976和0.971;②主要树种中,红松的重要值最大,其次为椴树、色木和杂木,冷杉的重要值最小;③林分分布格局为聚集分布,经显著性检验差异显著;不同树种分布格局有所不同,红松、杂木和色木为聚集分布,经显著性检验差异极显著,其它树种为随机分布;④主要树种存活曲线经线性回归,红松和色木存在显著的相关关系,椴树、云杉、冷杉不存在线性相关关系。

摘  要：
The diameter structure,importance value,distribution pattern and survival curve of broad-leaved Korean pine of over-logged forest in Jingouling Forest Farm was analysed.The results showed :(1)Diameter structure represented reverse "J" and the character of uneven-aged forest.The different distribution function fitting results showed the logarithmic function,inverse function,quadratic function,cubic function,compound function,power function,growth function,exponential function and logistic function adapted to the disciplinarian of diameter distribution,R2>0.922 and P≈0.Meawhile,the R2 of inverse function and cubic function were 0.976 and 0.971 respectively.(2)In the major tree species,the importance value of Pinus koraiensis,Tilia amurensis,Acer mono,mixed-tree,Abies nephrolepis were gradually decrease.(3) Distribution pattern in stand were in aggregated distribution and significant difference;Pinus koraiensis,mixedtree and Acer mono were aggregated distribution and very significant,other trees were in random distribution.(4)The survival curve of major tree species regressed through linearity,Pinus koraiensis and Acer mono were in significant correlation,but Tilia amurensis,Picea koraiensis and Abies nephrolepis were not in linear correlation.
