Diameter Class Structure and Spatial Correlation of Different Plant Species in Evergreen Broad-Leaved Forests
The diameter class structure and spatial correlation of typical evergreen broad-leaved forest in Longquan area,Baishanzu National Park,Qianjiangyuan-Baishanzu,Zhejiang Province were investigated system-atically.Long-term monitoring plots were set up in the study area to investigate woody plant individuals.The spa-tial pattern of different species/taxa is analyzed,and the species correlation at different scales are explored.The survey identified 4917 individual plants representing 122 species,with Schima superba dominating the flora.The diameter class structures of the primary species exhibit notable differences.Most of them were"L"type distribu-tion,and some were monocolumnar,discontinuous and normal type.Variations exist in the diameter-class level patterns among different species groups,indicating strong regeneration potential for dominant and common spe-cies,which are largely comprised of well-represented saplings,whereas rare species primarily consist of small trees.Spatially,dominant,common,and occasional species tend to cluster,whereas rare species show a random distribution pattern.The species diversity level of this stand is high,but different components were significantly different,reflecting their different response mechanisms to environmental heterogeneity and stress.
