Abstract:Species composition, flora analysis and species diversity features of 4 plots in Fokienia hodginsii community in Jinggangshan Nature Reserve, Jiangxi Province, were analyzed. The results showed that there were 59 species of vascular plants in Fokienia hodginsii community (including varieties), belonging to 32 families and 43 genera, in which the Pteridophyte accounted for 4 families, 4 genera and 5 species, the Gymnosperm 3 families, 3 genera and 3 species, and the Angiosperm 25 families, 36 genera and 51 species. The floristic analysis showed that the flora had come floristic constitents before Quaterary and retains many floristic element before Quaternary, the geographical element is complex, the temperate element dominanted, tropical and sub-tropical elements took larger proportion. Community of Fokienia hodginsii was many storied all-aged forest, community type was make up of Fokienia hodginsii and Castanopsis eyrei community, Fokienia hodginsii, Rhododendron simiarum and Castanopsis eyrei community. Fokienia hodginsii community had high species diversity index, which did not alter too much among plots, the variation patterns of species diversity of Fokienia hodginsii community were similar which ever the index was used. Generally, the order of the magnitude of species diversity was shrub layer＞tree layer＞herb layer.
