| 摘 要： | 以广西猫儿山自然保护区的2块1hm^2永久样地为基础，分析样地2003年8月和2008年3月胸径≥3cm的乔木层数据，比较2块样地乔木层物种多样性的时间动态和空间差异。结果表明：2003年2块永久样地共记录植物4515株，2008年共记录植物4237株，5年间数量减少6．16％；2块样地的植物均包含南亚热带常绿落叶阅叶混交林中常见的种类，共有种32种，海拔较高的样地含杜鹃科植物和温带成分明显增多；乔木个体数目、种类均随海拔增高、时间递增而降低。

| Abstract: | For long-term monitoring of the plant diversity and dynamics in Guangxi Mao' ershan National Reserve, permanent plots were established in 2003. In this paper, the species composition and dynamics of trees with DBH ≥ 3 cm were studied, based on surveys to the plots in Au-gust,2003 and March,2008. TheResults showed that there were 4 515 individuals in all,while 4 237 individuals were studied in 2008,which was 6.16% lower than that in 2003. Its florisric composition indicated that there were common subtropical evergreen broad-leaved and deciduous forest species,and 32 same species were found in 2 plots. The number and species of Rhododendron plants and temperate elements increased in the plot with higher latitude. The species abundance decreased when the latitude raised and time passed. |
