【摘要】Aims The objective of this paper is to quantify the species composition and spatial distribution pattern in a de-ciduous broad-leaved forest in temperate to subtropical ecological transition zone.
Methods In this study, a 3-hm2 forest was selected in the temperate to subtropical ecological transition zone to analyze the community species composition, structure of diameter at breast height, community classification and spatial distribution pattern of dominant tree species.
Important findings Our results showed that in the plot there were 85 species, 52 genera and 31 families, mainly composed of Betulaceae, Celastraceae, Caprifoliaceae, Salicaceae and Aceraceae. Quercus aliena var. acuteserrata and Pinus armandii are dominant species of the community tree layer. The rare species and occa-sional species accounted for 20.0% and 28.24% of total species respectively. Size distribution of all species showed an invert J-shape, which indicates that the community is in a stable and normal growth status. Using mul-tiple regression trees, the community in this plot can be divided into four categories:1) Quercus aliena var. acute-serrata+Pinus armandii+Litsea
