摘要
该文以长白山大面积分布的阔叶红松林林隙为研究对象,系统调查了林隙形成木和林隙填充者的特征,并对其主要树种的更新环境进行研究。结果表明,长白山阔叶红松林林隙多数是由1～4株形成木形成的,林隙形成木主要是红松、水曲柳、蒙古栎和紫椴;林隙填充者中,紫椴和色木槭的数量最多,红松所占比例较小。不同大小林隙内填充者的数量也不同,近似呈一个偏左的正态分布。现有的红松幼树一般都分布在林隙内或林隙边缘,更新环境良好。
Results showed that most of gaps were formed by 1 to 4 trees in the Changbai Mountain Natural Reserve. Major gap makers were Pinus koraiensis, Fraxinus mandshurica, Quercus mongolica and Tilia amurense. Gap fillers were mostly Tilia amurense and Acer mono, whereas Pinus koraiensis in a smaller number. The amount of fillers varied among different-sized gaps, which was almost in normal distribution deflecting to left. The regenerated young trees of Pinus koraiensis were normally distributed close to or within gaps where conditions were favorite for regeneration.
