| 摘 要： | 采用双向指示种分析法(TWINSPAN),将五台山7个冰缘地貌的植物群落划分为13个群丛.不同冰缘地貌植物群落类型的组成多样性有明显差异,根据13个群丛在不同冰缘地貌的分布状况,可区分为共有性群丛和专有性群丛.运用丰富度指数、物种多样性指数和均匀度指数对五台山7个冰缘地貌的综合群落多样性指数变化进行了分析,依据不同冰缘地貌植物群落综合多样性指数的大小排序,依次为冻融草丘石海石环冻融剥蚀面石河岩柱泥流坡坎和泥流舌.冰缘地貌的海拔、土层厚度、水分热量是影响植物群落植物种多样性指数变化的主要因素.

| Abstract: | Wutai Mountain is locates in the northeastern part of Shanxi province.Its highest peak,3 061 m a.s.l.,is also the highest peak in north of China and,therefore,nicknamed the roof of northern China.Based on the Two-Way Indicators Species Analysis,the seven periglacial landform plant communities in the Wutai Mountain can be divided into thirteen group clumps.The different periglacial landform plant community types' composition multiplicity has obvious difference.According to the distribution of different perig... |
