摘　　要：为研究亚热带常绿阔叶林淋漓锥群落分布特征,在福建省永春县蓬壶镇仙洞山的常绿阔叶林建立3个400 m^(2)调查样地,研究淋漓锥天然次生林群落的种类组成、数量特征、外貌特征、结构特征、物种多样性及群落的形成、更新与演替。结果表明:仙洞山天然林的淋漓锥通过实生和根萌条的繁殖方式,经过长期次生演替形成顶极群落。乔木层淋漓锥、青冈、木荷、枫香、栲类及余下7个从属种丰富度分别为68.6%、6.1%、5.1%、4.0%、4.0%和12.1%;灌木层以耐阴树种为主,覆盖度与上层乔木层稀疏度呈负相关;草本层稀疏,以耐阴草本植物为主,乔、灌、草分层明显。Three pieces of 400 m^(2) investigation plots were established in Xiandong mountain,Penghu Town,Yongchun County,Fujian Province to study the distribution characteristics of Castanopsis uraiana of drip cone community in subtropical evergreen broad-leaved forest.The species composition,quantitative characteristics,appearance characteristics,structural characteristics,species diversity,community formation,renewal and succession of drip cone natural secondary forest community were studied.The results showed that the climax community was formed in the natural forest of Xiandong mountain through long-term secondary succession by means of seedling propagation and root sprouting propagation.The richness of tree layer of Castanopsis uraianam,Cyclobalanopsis glauca,Schima superba,Liquidambar formosana,Castanopsisfargesii,and the remaining seven subordinate species was 68.6%,6.1%,5.1%,4.0%,4.0%and 12.1%,respectively.The shrub layer was dominated by shade tolerant trees,and the coverage was negatively correlated with the sparsity of the upper tree layer.The herb layer was sparse,mainly shade tolerant herbs.The stratification of arbor,shrub and grass was obvious.
