Abstract: The community characteristics of Cyclobalanopsis glauca in Zhejiang province were studied in order to provide reference for plantation management In this study, bidirectional indicator species analysis(TWINSPAN) was used to classify the community of Cyclobalanopsis glauca communis in the public welfare forest of Zhejiang province. The results showed that there were 7 types of Cyclobalanopsis glauca communis in Zhejiang Province, among which 4 were dominant communities with rich species composition and stable community structure, Cyclobalanopsis glauca communis was at the upper level of the community; there were 3 communities with Cyclobalanopsis glauca as the main associated tree species, all of which were in the early stage of succession. The results of this study laid a foundation for understanding the natural distribution characteristics and plantation management of Cyclobalanopsis glauca in Zhejiang Province.
