By using the vegetation quardat method, the population and its community of wild Gymnosphaera podophylla in Luofushan Nature Reserve of Guangdong were surveyed. The population and its community characteristics of G. podophylla were studied. The results showed that the population density of G. podophylla at Chaxianguan of Luofushan was 9.15×10~(-2) plants/m~2. The population distribution pattern was clumped, and the age structure was growing type. There were 127 species of vascular plants in the community of G. podophylla,which belonged to 63 families and 98 genera. The tropic and subtropical components had absolute dominance on the distribution types of families and genera,reflecting its characteristics of south subtropical flora. G. podophylla was the dominant species in the shrub layer.
