The zonal vegetation type of subtropical China is evergreen broad-leaved forest (EBLF). However, due to long term anthropogenic disturbance, primary EBLF is now scarce in this region; most of the EBLFs exist as secondary forests. Therefore, to preserve the regional forest biodiversity, it is important to understand the mechanisms underlying biodiversity maintenance of the regional secondary EBLF. One method for examining the mechanisms of forest biodiversity maintenance is to investigate the species composition and community structure on the basis of a large forest dynamics plot (FDP). According to protocols of Center for Tropical Forest Science (CTFS), we established a 9 ha FDP in the secondary EBLF of Wuyanling National Nature Reserve in Zhejiang Province, China, during 2011-2012. Here, we carried out analysis on species composition (e.g., importance value), community structure (e.g., floristic composition, size-class structure), and spatial distribution of woody plants with diameter at breast height (DBH) ≥1 cm. Results indicated that there were 71,396 woody plant individuals belonging to 200 species, 92 genera and 47 families within the FDP. The dominant families were Fagaceae, Lauraceae, Theaceae, Aquifoliaceae, Ericaceae and Symplocaceae. There were slightly more tropical elements than temperate elements found both at family and genus level. DBH size-classed community structure was reverse ‘J’ shaped, indicating abundant regeneration. Dominant species showed various shapes, such as reverse ‘J’, skewed or waved shapes, but no signs of population decline. Dominant species showed habitat priority and aggregated distribution patterns possibly related to habitat conditions, suggesting that habitat heterogeneity might be responsible to the spatial distribution of the dominant species in this FDP.
