Tsoongiodendron odorum Community in Xijingkeng Nature Reserve from Xinfeng, Jiangxi Province
摘要
Abstract
The Tsoongiodendron odorum community from Xijingkeng Nature Reserve in Jiangxi Province, was studied by the methods of quadrate investigation and community ecology. The results showed that:(1) there were 146 species of vascular plants, belonging to 66 families and 106 genera. Among them, 14 species of pteridophytes belonged to 10 genera in 9 families, and 132 species of seed plants belonged to 96 genera in 57 families. The geographical element analysis revealed that tropical elements took dominant positions. (2) Although evergreen plants were dominant, the physiognomy of the community had seasonal changes because of distribuiton of some deciduous species. The tree layer of the community could be divided into three sublayers. The dominant species in the tree layer were T. odorum, Machilus chinensis, Choerospondias axillaris and Neolitsea cambodiana; in the shrub layer, Cryptocarya chingii, Eurya loquaiana and Neolitsea chuii were dominant species. (3) The frequency grade of the community was A> B > C > D > E. The age structure analysis of dominant populations showed that the community was situated at the subclimax stage. (4) The biodiversity analysis showed that the diversity index including Simpson index and Shannon-wiener index arranged as shrub layer>tree layer>herb layer, and Pielou index arranged as tree layer>herb layer>shrub layer.关键词
