摘 要:
为了研究亚热带常绿阔叶林群落物种多样性的动态特征，在南岭大顶山和鼎湖山的常绿阔叶林各建立了1hm^2永久样地。根据对样地植物物种多样性测定，研究了两地植物物种多样性的空间分布特征和多度分布特征。结果表明，位于南岭大顶山的常绿阔叶林群落较鼎湖山的季风常绿阔叶林具有更高的物种丰富度，但具有较少的胸径≥1cm的乔木个体。南岭大顶山的常绿阔叶林大多数优势种的种群为集中分布，鼎湖山的常绿阔叶林优势种的种群具有相对较多的规则分布。[著者文摘]

Abstract:
For long-term monitoring and study of plant species diversity, two plots （ each 100 m×100 m ） were set up in the evergreen broad-leaved forests in Nanling Dadingshan Nature Reserve and Dinghushan Nature Reserve respectively. On the basis of investigation of each plant with DBH≥1 cm in the plot, and of the shrubs and herbs in 5 m×5 m quadrates of the plot, this paper expounded the physiognomy, structure, species diversity of the community. The results showed that the species abundance in Nanling Dadingshan Nature Reserve evergreen broad-leaved forest is higher than that of Dinghushan, but with less tree individuals DBH〉1 cm. In Nanling Dadingshan, most dominant species populations are clumped, but in Dinghushan evergreen broad-leaved forest more dominant species populations are distributed at relatively uniform pattern.[著者文摘]
