Characteristics of Pinus kwangtungensis Community in Luokeng Nature Reserve,Guangdong Province

  • Characteristics of Pinus kwangtunensis community in Luokeng Provincial Nature Reserve,Qujiang,Guangdong Province,were studied using quadrat method for better conservation of the national endangered species.There are 237 species of vascular plants belonging to 74 families and 126 genera in a sampling area of 3400 m>.The dominant families of community are Fagaceae,Lauraceae,Ericaceae,Rosaceae,Theaceae and Aquifoliaceae.The dominant species of the community are P.kwangtungensis,Schima remotiserrata,Rhododendron simiarum,and Pentaphylax euryoides.Most of the floristic elements of seed plants at the familial and generic level are Pan-tropical and tropical-Asia areal-types,which show some transition character of southern and mid-subtropical elements.Analyses on the species age structure indicate that the edificatory species population of P.kwangtungensis intends a declining population.The dominant species populations of S.remotiserrata,R·simiarum,and P.euryoides are in relative stable stage,meanwhile the species population of Cyclobalanopsis obovatifolia and Podocarpus macrophyllus var·maki will apparently increase their population size because there are a lot of seedlings in the generation layer.
