Abstract:

Characteristics of the Osmanthus yunnanensis community distributing in Donglashan region of Hengduanshan Mountain were investigated in this paper. The results showed that O.　yunnanensis community had remarkable change over seasons. Phanerophyta was the most dominant, though cryptophyta and hemicryptophyta also held big proportion. Vascular plants in the community mainly had simple leaf, nonentire leaf and herby leaf, with mediumsized leaves. The community had obvious layers with simple structure， it could be divided into arbor layer, shrub layer, grass layer and interlayer. The community was in the stage of steady succession and O.yunnanensis was the dominant species with important value of 42.47.
