摘　　要：2015—2016年间,基于1. 8 hm^2固定样地数据分析广东石门台自然保护区森林植被的优势物种及其科、属组成。结果表明:在样地中,植株个体胸径≥2. 5 cm的种子植物有55科117属211种,其中以山茶科(Theaceae)、樟科(Lauraceae)、柿科(Ebenaceae)、紫金牛科(Myrsinaceae)、虎耳草科(Saxifragaceae)、杜鹃花科(Ericaceae)的优势最明显;优势属为木荷属(Schima)、柿属(Diospyros)、润楠属(Machilus)、柃木属(Eurya)、鼠刺属(Itea)、密花树属(Rapanea)等;优势种为罗浮柿(Diospyros morrisiana)、木荷(Schima superba)、疏齿木荷(S. remotiserrata)、鼠刺(Itea chinensis)、密花树(Rapanea neriifolia)、华润楠(Machilus chinensis)等。通常构成亚热带常绿阔叶林最优势的壳斗科植物,在本区虽有3属10种,但它们的重要值之和仅5. 33%,远低于山茶科(63. 34%)、樟科(37. 52%)、柿科(23. 32%),表明石门台森林植被的物种组成较为特殊。During the period of 2015 to 2016,based on the data of the 1. 8 hm^2 permanent quardats,the dominant family,geneus and species compositions of the forest vegetation in Shimentai,Guangdong were analyzed in this paper,so as to better know the dynamic of the plant resources and strengthen the protection of the plants in the natural reserves. Results showed that there were 211 species（ plant individuals with breast height diameter more than 2. 5 cm）,which were belonging to the 55 families and 117 genera in plot areas. Among them,the most dominant families were Theaceae,Lauraceae,Ebenaceae,Myrsinaceae,Saxifragaceae,Ericaceae,et al.,where the most dominant genera were Schima,Diospyros,Machilus,Eurya,Itea,Rapanea,et al.,and the most dominant species were Diospyros morrisiana,Schima superba,S. remotiserrata,Itea chinensis,Rapanea neriifolia and Machilus chinensis. In this area,there were 10 species belonging to 3 genera of Fagaceae which were in general the most dominant in evergreen broadleaved forest of subtropical,and the total important values of them were only 5. 33%,were far lowest than that of Theaceae with 63. 34%,Lauraceae with37. 52% and Ebenaceae with 23. 32%,showing that the species composition of forest vegetation in Shimentai had its own especial characteristic.
