森林群落中的物种多样性对维持森林群落的稳定、发展、演替及碳汇评估等具有重要的作用。本研究利用样方调查方法，通过Margalef指数、Shannon-Wiener指数和Pielou指数分析广东省不同气候带灌木植物的物种组成及其多样性。结果表明：广东省中亚热带灌木层物种分属68科156属302种，南亚热带分属58科140属225种，北热带分属20科27属29种；灌木层植株密度和平均高度由北向南递减；桃金娘是广东省灌木群落的主要物种；中、南亚热带内，人工林和天然林中灌木的丰富度指数和多样性指数相差不大；人工林灌木物种的丰富度指数和多样性指数随纬度的降低而逐渐减小，均匀度指数随纬度降低表现出缓慢的增加趋势。

The diversity of species in forestry community plays an important role in maintaining forestry community stability,development and succession as well as in evaluating forest carbon sequestration.Species com-position and diversity for shrubbery in different climatic zone were analyzed based on the Margalef index,Shannon-Wiener index and Pielou index by using quadrant method in Guangdong province.The results showed that,shrub plant belonged to 68 families 156 genera and 302 species in mid-subtropics,58 families 140 genera and 225 species in south subtropics and 20 families 27 genera 29 species in north tropic.Plant density and average height decreased from north to south,moreover,Rhodomyrtus tomentosa was the main composition of shrub in Guangdong.Richness index and diversity index didn′t show significant difference between artificial and natural forest in the mid- and south subtropical climatic zone.In addition,richness index and diversity index in artificial forest decreased gradu-ally with the decrease of latitude,but evenness index was on the contrary.
