Species composition and community structure of evergreen broad-leaved forest in Nankunshan Nature Reserve
To explore the characteristics of forest community species composition and structure in the Nankunshan Nature Reserve,the sample plot survey method was used to investigate all woody plants with a breast height diameter≥1 cm in the sample plot,and their community tree species composition,distribution pattern of tree species abundance and diameter class structure were analyzed.The results showed that there were a total of 2 576 woody plants with a breast height diameter of≥1 cm in the sample plot,belonging to 35 families,60 genera and 98 species.There were 22 genera and 53 species in 6 dominant families including Lauraceae,Fagaceae and Rubiaceae.Machilus chinensis,Neolitsea chui and Lithocarpus hancei were the dominant tree species;There were 16 rare species and 37 occasional species in the sample plot;Tree diameter class followed an inverted"J"shape distribution.This indicated that the overall structure of the community was stable,the growth status of trees was healthy,there were no obvious faults in the plot,and the community was generally well updated.The research results provided references for understanding the forest ecosystem and protecting its biodiversity in the study area.
