摘　　要：通过样方调查,对江苏龙池山自然保护区的宁波木犀群落的区系组成、群落结构和种群特征进行了统计分析,结果表明:群落中维管植物共有71科127属149种,其中蕨类共8科14属16种,种子植物63科113属133种,其中壳斗科、樟科、金缕梅科、山茶科、山矾科、蓝果树科、冬青科是群落优势科,区系成分以泛热带分布和北温带分布为主,具有明显的热带向温带过渡的特征。群落郁闭度较高,常绿成分占绝对优势,以青冈为建群种,宁波木犀、油茶、米槠等为伴生种,其中宁波木犀种群呈集群分布,年龄结构不均衡,缺乏成年大树,受破坏严重,亟待保护。Based on the field investigation on the Osmanthus cooperi community in Jiangsu Longchi mountain, the floral composition, community structure and population characteristics were analyzed. The results showed that： there are 149 species which belonging to 127 genera and 71 families, including 8 families 14 genera 16 species ferns and 63 families 113 genera 133 species seed plants. The dominant families were Fagaceae, Lanraceae, Hamamelidaceae, Theaceae, Symplocaceae, Nyssaceae and Aquifoliaceae. The flora showed an obviously transitional characteristics, by the Pantropic and North Temperate were both the main elements. The community had high canopy density, and the evergreen trees were predominant by Cyclobalanopsis glauca, accompanying with Osmanthus cooperi, Camellia oleifera, Castanopsis carlesii, et al. Because of the human activities, the Osmanthus cooperi population was aggregate distributed and lack of adult trees. It＇s urgent to take effective actions to protect the population.
