Study on flora composition and species diversity of Changiostyrax raxdolichocarpa communities in northwestern Hunan province
摘要
Abstract
The vegetation data of Changiostyrax raxdolichocarpa population forest in Hupingshan and Sangzhi, Hunan province were used as the information for studying the flora composition and species diversity. The results showed that a total of 82 families( 153 genera,229 species) of vascular plants were found within these two sample plot, including 7 families(ll genera, 16 species) of peridophyte; 1 family ( 1 genera, 2 species) of gymnospperme, 74 families ( 141 genera, 211 species) of angiospermae. The floristic elements are complex, strong tropical geographical elements were found at family-level and genus-level. Vertical structure of the community is also complex, dominated by mesophanerophytes and microphanerophytes. The community is rich in plant species, especially the diversity of shrub layer, which were higher than those of the tree layer and herb layer.关键词
