关 键 字：灌木草丛；物种多样性；海拔；演替 |
| 摘 要：灌木草丛是南亚热带植被演替序列之一的初级阶段。对鼎湖山自然保护区灌木草丛的植物物种多样性格局及其变化的研究结果表明，环境因子对植物群落的物种组成及多样性格局影响较大。各群落的种类组成因环境因子的变化而变化。当海拔自低至高变化时，物种丰富度下降，而其它a多样性指数的格局和变化比较复杂，无明显趋势。人类活动对灌木草丛的种类组成和群落多样性影响较大。在自然状态下，灌木草丛向稀树灌丛再向季风阔叶林演替。保护愈严格，演替速率愈快。 |

关 键 字(英文)：Shrub-grassland；Species diversity；Elevation Succession |
| 摘 要(英文)：Shrub-grassland is the first stage of one of the vegetation succession series in South China. The species diversity pattern and its variation of shrub-grassland communities in Dinghushan from 1982-2001 were studied and the results showed：Environment factors affected heavily on species composition and diversity pattern. Species richness decrease as elevation increase. Other a diversity indices showed no distinct trends. Species composition and diversity were effected by human disturbance. Shrub-grassland would become open forest and then become monsoon evergreen broadleaved forest in nature. The succession would be fast when these communities under strict conservation. |
