The typical Tapiscia sinensis community in Guanshan Nature Reserve of Jiangxi Province was investigated and studied. The results are as follows. There are 104 species belonging to 78 genera and 54 families. The generic areal-types are mainly composed by North Temperate, followed by Pantropic, which demonstrates a typical mid-subtropical montane community. The analysis of the important value of the stumpage species shows that Castanopsis tibetana, T. sinensis, Phoebe sheareri and Alniphyllum fortunei are domiment species of the community. The analysis of diameter class and height class shows that T. sinensis population is in decline stage but basically stable and rather competitive as the result of its dominance at the top level. The Raunkiaer frequency grade of the community is A>B>D>C>E, which is consistent with subtropical montane evergreen broad leaved forest. Simpson diversity index D=0.88, Shannon-Wiener diversity index H=3.65, Pielou evenness EH=0.73. With relatively high community diversity, the community of T. sinensis investigated in this paper is one of the few T. sinensis communities in Guanshan area, which has important scientific research value and tangible value. However, the group of T. sinensis is in declining form, so it is advisable to protect it in situ or ex situ in the future.
