Abstract: On the basis of field investigation of a 1 600m2 plot,We analyzed physiognomy,structure,the floristic composition and species diversity of a Rhodoleia championii community in Donguan Yinpingshan Forest Park,Guangdong. There were 153 vascular species,belonging to 116 genera and 73 families. Trop. & Subtrop. elements were the dominant. The community was mainly dominated by Rhodoleia championii. The vertical structure of the community was composed of Tree layer,shrub layer,herb layer and rich interstater plants,and dominated by evergreen plants in Microphanerophytes. According to the Raunkiaer Frequency Law,species in 1-20% occurrence frequency dominated the community,accounting for 67.97% of the total species. Because of the human interference,the number of the Saplings and young Rhodoleia championii trees was less,which indicates the population was on the declining trend. The different diversity indices showed different trend among layers in the community except that the shrub layer had the highest diversity.

Key words: Dongguan, Rhodoleia championii, community, species diversity, community characteristics
