摘　　要：以关帝山华北落叶松林林隙为研究对象,调查研究了林隙大小结构、林隙内落叶松更新苗数量分布特征以及林隙内落叶松空间分布特征。结果表明:第一,在华北落叶松林中,50m2～150m2之间的林隙居多数;第二,在不同大小的林隙中,100m2～150m2之间的林隙内的落叶松更新苗株数最多;第三,在不同大小的林隙内,落叶松更新苗均呈集群分布。在采伐森林资源时,我们可以尽量模拟最适于落叶松更新的天然林隙大小进行择伐,以创造有利于更新的微环境。Taking Larix pfincipis-rupprechtii Mayr forester in Guandi Mountain as the research object, this paper studies the structure of the gap size, the distribution features of the number of regenerated larch seedling in the gap as well as the features of the spatial distribution of Larix in the gap. The results show that： （ 1 ） in Larix principis-rupprechtii Mayr forster, the most of the gaps are 50 m^2-150 m^2; （2）in the different sizes of the gaps, the amount of larix regenerated seedlings is the most in the gaps of 100m^2-150 m^2; （3） in the different sizes of the gaps, larix regenerated seedlings are cluster distribution. Connecting （ 1 ）and （2）, when we cut forest resources, we could simulate the most favorable size of the gap that for larix regeneration to create the favorable micro-environment for the generation.
