摘　　要：羊台山位于深圳西北部,最高海拔587.1 m,是深圳城区北部的生态屏障,尚存较好的南亚热带次生阔叶林。自2006年,在羊台山等布设2个面积为1200 m2的固定样地,定位研究深圳羊台山次生林典型群落黄牛木群落的物种组成、群落结构特征和物种多样性,旨在为深圳地区乡土植被的恢复与重建提供科学依据。结果表明:(1)样地内黄牛木群落有维管植物132种,隶属48科70属,样地1以黄牛木为单优势种,样地2以银柴为单优势种;(2)生活型谱分析可见:高位芽植物占物种数的60%以上,与我国云南东南和浙江典型亚热带常绿阔叶林较为接近,略低于广东鼎湖山典型南亚热带次生阔叶林;(3)群落垂直结构方面,样地1有较明显的分层,黄牛木主要分布于乔木层14—9 m高度级,样地2整体分层不明显,黄牛木多处在14—5 m的高度级;(4)黄牛木群落的主要种群处于稳定发展阶段,样地1中黄牛木属稳定型种群,银柴属增长型种群,水蒲桃属发展型种群,样地2银柴、杉木、水杨梅以及黄牛木均属稳定型种群;(5)物种多样性指数与均匀度指数分析结果表明,样地1属演替中期群落,样地2属演替中前期群落。The Yangtaishan, located in the northwest of Shenzhen city with highest elevation of 587.1m, is an important ecological barrier for the north of urban area in Shenzhen where saved a large secondary subtropical broad-leaved forests. Since 2006, two fixed-plots, with each area for 1200 m2, were established for an attempt to understand the specie＇s composition and community structure of the secondary forest. The results indicated that： （1） There were 132 vascular plants species belonging to 48 genera and 70 families in the two plots. Cratoxylum cochinchlnense was found to be the single dominant species in the plot one, while Aporosa chinensis was the single dominant species in the plot two. （2） The analysis of life-form spectrum showed that phanerophytes species were accounted for more than 60%, which was close to the typical subtropical evergreen broad-leaved forest in the southeast of Yunnan and Zhejiang, and slightly lower than the typical south tropical secondary broad-leaved forest at Dinghu Mountain. （3） For community vertical structure, the stratification of the plot one was obvious but the plot two was not. In the plot one, community of Cratoxylum cochinchlnense mainly distributed among tree layer 14-9 m range while most of them distributed among height of 14-5 m in the plot two. （4） The main dominant species in Cratoxylum cochinchlnense community are in a stable development stage. In the plot one, Cratoxylum cochinchlnense was found to be a stable population, Aporosa chinensis a growing population and Syzygium jambos a developing population. While in the plot two Aporosa chinensis, Geum aleppicum, Cunninghamia lanceolata and Cratoxylum cochinchlnense were all found to be the stable population. （5） The Species diversity index and evenness index analysis results showed that the community for the plot one belonged to belonged to the earlier-middle period. the metaphase of the vegetation succession and the plot two
