摘要 据对2个100m2样地统计,共含维管束植物66种分属32料58属.群落区系以樟、茜草和山茶等科的属种居多数;热带、泛热带地理成分分别占总属数的44.5%和33.3%.树种以米槠、木荷、青冈和红勾栲为主,林下多见九节木、朱砂根等雨林种类,显示群落是当地基带植被南亚热带雨林向高海拔山地常绿阔叶林过渡的类型. This paper deals with the floristic composition, structure and synthetical features of tree species on the mountian broad-leaf forest of warm tharacter of Naitian in Tongan, Xiamen. According to the surveys of 200m2 in 2 plots, there are 66 species of vascular plants belonging to 58 genera in 32 families. Analysis of floristic geographical elements indicated that the percentage of tropical and pan-tropical elements (such as the genera of Lauraceae, Rubiaceae and Theaceae, etc. ) are dominant, making up 44. 5% and 33. 3% of the total numbers of genera respectively. The community of Naitian in Tongan is Chiefly Castanopsis carlesii, C. lamontii, Schima su-perba, Cyclobalanopsis glauca and Engelhardtia roxburghiana, etc. Analysis of floristic composition indicated that this forest is the transition type from foundational vegetation zone of south ?subtropical rain forest to mountion evergreen broad-leaf forest on higher altitude.
