摘  要：
设于喀纳斯湖区临时样地调查数据基础上,分析木本植物幼苗基本特征及优势幼苗在不同尺度上的空间分布格局。共记录到的已定木本植物幼苗591株(5种),其中西伯利亚云杉幼苗在所有指标上均占绝对优势,其次是西伯利亚红松,二者为稳定的林下组成者及幼苗库阶段的补充者。木本植物幼苗密度为1.51±0.22株/m~2、丰富度为1.64±0.17种/m~2,大多幼苗长势良以上;大尺度上各幼苗空间位置随机性较为明显,集群分布不明显,而在小尺度上,聚集性显著。西伯利亚云杉幼苗前期多以随机分布为主,后因更新主要在林窗内进行,所以小尺度上幼苗表现出高度聚集分布。

摘  要：
Based on the survey data of Kanas Lake area,the basic characteristics of woody plant seedlings and the spatial distribution pattern of dominant seedlings on different scales were analyzed in this paper.A total of 591 strains(5 species)of woody plants were recorded,among which Picea obovata seedlings had an absolute advantage on all indexes,followed by Pinus sibirica.Both for the stability of the forest under the composition and seedling stage of the supplement.The seedling density of woody plants was 1.51±0.22 plants/m~2,the richness was 1.64±0.17/m~2,and most of the seedlings grew well.The spatial distribution of the seedlings on the large scale is obvious,the cluster distribution is not obvious,but the clustering is significant on the small scale.Siberian spruce seedlings were mainly distributed in the early stage,and the regeneration was mainly carried out in the gap,so the seedlings on the small scale showed a high degree of aggregation distribution.
