摘要/Abstract

摘要： 基于河北省木兰围场国有林场管理局域内2hm²典型天然次生林植被群落调查,探讨次生林下灌木群落结构特征,研究显示:1) 研究区29 种灌木分属于15 科22属,包含灌丛12 878丛、灌木20 861株,以毛榛(Corylus mandshurica)、五角枫(Acer mono)幼苗、锦带花(Weigela florida)为该群落优势种;2) 80%以上的灌木基径过1cm,尤以青杄(Picea wilsonii)和华北落叶松(Larix principis-rupprechtii)幼苗的平均基径最大;3) 以2m高度为界限可将灌木划为两层,上层灌木基径和冠幅明显优于下层灌木;4) 从空间分布角度而言,不同灌木种群在频度、相对显著度和相对多度等方面表现出一定的空间异质性。

Abstract: Based on the vegetation investigation of a 2 hm² plot in the typical natural secondary forest in Forest Bureau of Mulan-Weichang,Hebei Province,this paper analyzes structural characteristics of shrub community. The results indicate:(1)A total number of 29 shrub species of 15 families,22 genera are found in this survey,including 12 878 clusters,20 861 individuals,Corylus mandshurica,Acer mono seedlings and Weigela florida are three dominant species in this shrub community; (2)The diameter of about 80% shrubs is more than 1cm,especially Picea wilsonii and Larix principis-rupprechtii seedings; (3)Shrubs can be divided into two layers by a height of 2 m boundary and the upper shrubs are superior to the lower ones in terms of diameter and crown; (4)From the perspective of spatial distribution,shrubs show some spatial heterogeneity in frequency,relative saliency and relative abundance,etc.

Key words: natural secondary forest, shrub, community characteristics, species composition, space structure
