Abstract: In order to further explore the restoration effect and succession pattern of natural secondary forest after Phyllostachys edulis clear-cutting, one fixed sample plot of 100 m×100 m was established in Tianmu Mountain National Nature Reserve in Zhejiang Province in 2023, where all living woody plants with a diameter at breast height （DBH）≥3 cm were tagged, identified, measured and mapped so as to obtain the analysis of species composition, faunal distribution, diameter structure and vertical structure of community.Results are as follows: （1）In the plot, 6 412 individuals belong to 110 species 85 genera 49 families including broad-leaved evergreen ,deciduous broad-leaved and coniferous species , accounting for 24.5%, 71.8% and 3.7% of total species respectively. （2） The top 3 dominant species ranked by the importance values are Mallotus apelta, Cunninghamia lanceolata and Cyclobalanopsis myrsinifolia, of which accounts for 26.2 % of the total important value .（3）The community with stratification is obvious and the vertical structure is composed of canopy layer （12 species）, sub-canopy layer （59 species） and shrub layer （106 species）. （4）The DBH of all individual of community generally fitted an “inverted-J” distribution, indicating good natural regeneration across the community and“inverted-J” “L”, single peak or double peak distribution for diameter structure of the dominant species.（5）On the level of the family, the tropical and temperate floristic elements primarily make up 56.76% and 43.24% separately, while at genus level, the tropical 52.38%, the temperate 41.67%. The secondary community with higher species diversity, more complex vertical and diameter structure is still in the primary stage of succession with deciduous species taking a dominant position in Tianmu Mountain.
