Study on Structural Characteristics of Shrub Community in Typical Natural Secondary Forest in Hebei Province

Abstract

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
