The composition, physiognomy, structure and dynamics characteristic, species diversity of the Cinnamomum japonicum varchenii community were studied based on community investigation. The results showed that 71 species in 63 genera 46 families of vascular plants were recorded in 7 plots in total of 700 m2. The analysis on species important value showed that Cinnamomum japonicum varchenii, Celtis sinensis, Ficus erecta varbeecheyana, Machilus thunbergii are dominant species of the community. The physiognomy of the community is ever green all year around. The age structure of dominant populations showed that three out of four main populations of the community are increasing populations. The species diversity of the community is measured with the Margalef index of 99917, the ShannonWiener index of 30657, the Simpson index of 09007, and the evenness index of 07192. The diversity pattern from maximum to minimum is herb, arbor, shrub. Diversity comparison with 4 other different communities showed that the species diversity of Cinnamomum japonicum varchenii community is slightly lower.
