摘　　要：对珠海淇澳岛地区肉实树占优势的植物群落进行研究,结果表明:(1)肉实树群落中共有维管植物38科51属61种,种类组成具有极强的南亚热带性质;(2)年龄结构显示群落的主要优势种属于稳定型种群,群落总体处于稳定状态;群落的频度指数规律为A>B>C>D<E,与RaunKiaer频度规律相一致;(3)物种多样性指数为D=13.70,H=4.12,均匀度指数为E=0.39,E′=0.82,群落物种多样性指数和均匀度指数均较高,接近典型南亚热带常绿阔叶林顶极群落类型。Results from a study on Sarcosperma laurinum communities from Qi-ao Island in Zhuhai city, Guangdong province, showed that： （1） 61 species of vascular plants belonging to 38 families and 51 genera were found in the Sarcosperma laurinum community, with the floristic components of the community exhibiting a south subtropical property; （2） Analysis for the age structure of the community showed that the dominant species belonged to some stable populations, and the frequency index of the community was A 〉 B 〉 C 〉 D 〈 E, which was consistent with Raunkiaer＇s frequency law; （3） For species diversity of the community, D = 13. 70, H=4. 12, E=0.39, E＇ =0. 82. Results indicated that the diversity and evenness indices were closed to those of a climax community from a typical subtropical evergreen broad-leaved forest.
