摘　　要：通过样方调查,对广东南岭国家级自然保护区管理局秤架管理处辖区内海拔500 m左右的常绿阔叶林群落组成结构特征进行了分析。结果表明,在2 000 m2的样地内共有维管束植物85科152属202种(含变种),以热带成分为主;群落中猴欢喜和罗浮栲为优势种,重要值分别为为26.16和24.51,因此将该群落命名为猴欢喜+罗浮栲群落(Sloanea sinensis+Castanopsis fabri Community)。群落成层现象明显,可分为乔木层、灌木层和草本层3个层次,层间植物丰富;生活型以高位芽为主;叶型以中型革质单叶为主;乔木径级以小径级为主。按Raunkiaer标准,种群频度分布规律为A>B>C>D>E。群落内的种群频度为1%～20%的种类占优势,占总种数的61.88%。We analyzed the characteristics of an evergreen forest community in Guangdong Nanling National Nature Reserve by filed investigation of a 2 000 m2 plot at the altitude of 500 m.Results showed that there were 202 vascular species belonging to 152 genera and 85 families.Pantropic elements were the dominant,followed by Tropical and Temperate elements which showed obviously transitional characteristic.The community could be named as Sloanea sinensis＋Castanopsis fabri community according to species importance value.The community was obvious dominated by Sloanea sinensis（IV 26.16） and Castanopsis fabri（IV 24.51）.The vertical structure of the community was composed of arbor,shrub and herb layers,and interlayer species were abundant.The phanerophytes were mostly in life form,and the mesophyll and microphyll were dominate.The structure of the community indicated that young trees were the main component.According to the Raunkiaer Frequency Law,the frequency distribution from the Raunkiaer was A〉B〉C〉D〉E.Species in 1% ～20% occurrence frequency dominated the community,accounting for 61.88% of the total species. 更多
