Abstract: Four artificial bamboo communities and one virgin community of Camellia sinensis var. pubilimba in Renhua county, Guangdong province were studied by quadrate investigation and community ecology analysis. The results showed that: (1) In 5 wild Camellia sinensis communities, there were 177 species of vascular plants, belonging to 119 genera in 63 families, including 21 species of pteridophytes belonging to 17 genera in 13 families, and 155 species of seed plants belonging to 101 genera in 49 families. (2) The dominant species in the tree layer were Phyllostachys heterocycle & Cunninghamia lanceolate (artificial bamboo community) or Machilus chinensis & Luculia gratissima (virgin community); the dominant species in the shrub layer were Camellia sinensis var. pubilimba, Alchornea trewioides, Lindera nacusua; The dominant species in the herb layer were Blechnum orientale, Microstegium fasciculatum, Tetrastigma hemsleyanum. (3) In addition to the secondary forests, Simpson index, Shannon-wiener index and evenness of herb layer in other communities were higher than those of tree layer and shrub layer, which may be the result of the combined action of natural succession process and human logging activity. (4) Wild Camellia sinensis var. pubilimba was more suitable for secondary forest under moderate disturbance. The relatively wet sunny slope was conducive to its development. (5) There were 258 wild Camellia sinensis var. pubilimba strains in 5 communities, but they were all seedlings, and the growth condition was not very well. Effective protection and moderate interference should be taken, meanwhile, the public education should be carried out to protect the existing wild resources.
