The investigation of characters of Manglietia patungensis Community in Guanshan National Nature Reserve of Jiangxi Province showed that:there are abundant species components and complicated floristic elements in M. patungensis community.In terms of genus geographical composition,more of them are distributed in tropical zones.According to Raunkiaer's statistics of life-form,the phaenerophyte in the community composition take primary position and the hemicryptophyte are the second.Regarded to the leaf characteristics,the community is mainly composed of mesophyll,microphyll,simple leaf,sclerophyll and unentire leaf.The vertical structure of community is relatively complicated,where the species diversity of undergrowth layer is apparently greater than tree layer.The structure of whole M. patungensis community is stable and contagious distribution.
