通过样方调查,对广东南岭国家级自然保护区秤架管理站辖区内海拔1 400 m左右的疏齿木荷(Schimaremotiserrata)+福建柏(Fokienia hodginsii)落的物种组成、群落结构和物种多样性进行分析.结果表明,在1 600 m~2的样地内共有维管束植物45科75属113种,以泛热带成分为主,热带和温带成分也有一定的比例,表现出较为明显的过渡性质;群落组成以疏齿木荷、福建柏和青茶冬青(Ilex hanceana)等为主,成分复杂,类型多样,优势种优势地位分散而不明显;群落分为乔木层、灌木层和草本.藤本层3层,层间植物稀少,生活型以常绿小、中高位芽植物为主,分别占30.97%和27.43%;按Raunkiaer标准,群落内的种群频度为1%～20%的种类占优势,为总种数的55.75%,福建柏种群以低龄幼树为主,呈增长状态;丰富度指数、Shannon-Wiener指数、Sknpson指数和均匀度指数等均表现出相同的趋势,为灌木层>乔木层>草本.藤本层.

We analyzed the floristic composition, structure, physiognomy and species diversity of a Schima remotiserrata + Fokienia hodginsii community in Nanling National Nature Reserve, Guangdong, by field investigation of a 1 600 m~2 plot at the altitude of 1 400 m.Results showed that there were 113 vascular species, belonging to 75 genera and 45 families.Pantropic elements were the dominant (20.59%), followed by Tropical and Temperate elements which showed obviously transitional characteristic.The community was mainly dominated by Schima remotiserrata, Fokienia hodginsii, and Ilex hanceana, and of complex structure.However, the dominant components scatteredly distributed and were not obviously enough.The vertical structure of the community was composed of arbor, shrub and herb-liana layers, and dominated by evergreen plants in Microphanerophytes (30.97%)and Mesophanerophytes (27.43%).According to the Raunkiaer Frequency Law, species in 1%～20% occurrence frequency dominated the community, accounting for 55.75% of the total species.Saplings and young trees comprised the F.hodginsii population, indicating the population was in pioneer stage and with growing status.The diversity indices, such as Margalef richness index, Simpson dominance index, Shannon-Wiener index and Pielou evenness index showed similar trend, with shrub layer > arbor layer > herb-liana layer in the community.
