| 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。
