摘　　要：用植被样方法对广东罗浮山自然保护区的野生黑桫椤种群及所在群落进行了调查,研究了罗浮山黑桫椤种群与群落特征。结果表明:罗浮山茶仙观黑桫椤的种群密度为9.15×10-2株/m2,种群分布格局呈集群分布,年龄结构属增长型。黑桫椤种群所在群落有维管植物127种,隶属于63科98属,植物科、属的分布型以热带、亚热带占绝对优势,反映了该群落以热带亚热带成分为主的南亚热带区系特点;黑桫椤在灌木层中占优势地位。By using the vegetation quardat method,the population and its community of wild Gymnosphaera podophylla in Luofushan Nature Reserve of Guangdong were surveyed.The population and its community characteristics of G.podophylla were studied.The results showed that the population density of G.podophylla at Chaxianguan of Luofushan was 9.15 × 10-2 plants/m2.The population distribution pattern was clumped,and the age structure was growing type.There were 127 species of vascular plants in the community of G.podophylla,which belonged to 63 families and 98 genera.The tropic and subtropical components had absolute dominance on the distribution types of families and genera,reflecting its characteristics of south subtropical flora.G.podophylla was the dominant species in the shrub layer.
