长白山针阔混交林乔木幼苗组成与空间分布
Composition and spatial pattern of tree seedlings in a coniferous and broadleaved mixed forest in Changbai Mountain of northeastern China
摘要
Abstract
[Objective]This paper is to understand the species composition and spatial distribution of tree seedlings in a coniferous and broadleaved mixed forest in Changbai Mountain of northeastern China. It may provide a theoretical basis for management. [Method]Based on a permanent plot in the coniferous and broadleaved mixed forest and continuously field survey tree seedlings and adult trees within 1 ha, we analyzed species composition and spatial distribution of typical coniferous tree and broadleaved tree seedlings. The relationship of spatial distribution between seedlings and adult trees was further researched. [Result]The results showed that:(1) a total of 17 tree species were recorded in this plot which was consistent with the composition of adult trees,and there were 10865 tree seedlings recorded;(2) seedlings of typical coniferous trees ( Pinus koraiensis, Abies nephrolepis) and broadleaved trees (Fraxinus mandshurica, Tilia amurensis) were characterized by clumped distribution on the scales less than certain critical points;(3) the spatial distribution of F. mandshurica and T. amurensi' s seedlings was positively correlated with their adult trees, while that of P. koraiensis and A. nephrolepi's seedlings was negatively correlated with their adult trees. [ Conclusion] All above, in the coniferous and broadleaved mixed forest, spatial distribution of typical coniferous tree and broadleaved tree seedlings showed clumped distribution, and the typical broadleaved tree seedlings were positively correlated with their adult trees while the typical coniferous tree seedlings showed negative correlations with their adult trees.关键词
