Abstract: The present paper deals with the secondary forest vegetation after 20 years period of natural regeneration. The field study was carried out on Mt. Wuchao near Hangzhou, Zhejiang Province. According to Jaccard’s community index of similarity, the secondary vegetation was divided into three types: the deciduous mixed forest, the evergreen mixed forest-a sere towards a higher stage of evergreen broad-leaf climax community, and intermediate type. The life forms were according to Raunkiaer’s classification:phaenerophyta (74.4%), chamaephyta (13.5%), hemicryptophyta (4.1%), geophyta (6.8%), and therophyta (1.4%). The high percentage of phaenerophyta is similar to the life form spectrum of the evergreen broad-leaf forest of Zhejiang Province. The leaf size of the vegetation was mainly microphylla (60.3%) but which is higher than those of the evergreen broad-leaf forest in other place of the province. 82.5% of the leaf pattern was simple leaf. The recovery vegetation stratification were divided into arborous layer, shrub layer, herbaceous layer and ground layer. According to Lutz’s phytograph index the most important tree species were:Lithocarpus glaber, Cyclobalanopsis glauca, and Quercus glandulifera var. brevipetiolata in which density, frequency, cross-sectional area and its appearence in the under and over story were predominant. Next is Castanopsis fargesii, Castanopsis sclerophylla and Schima superba. The recovery forest has a growing-stock of 50m3 per hectare, the highest is found to be above 140m3 per hectare. A total of 62 species of spermatophyta in 27 families and 45 genera was observed in the field during the study period and a comparison of its flora and geographical distribution was carried out.
