摘要： 用5种β多样性指数，研究了五台山旅游活动对草甸植物群落β多样性的影响。结果表明：① 草甸群落的β多样性主要受到旅游干扰和种间竞争的共同影响，在不同群落类型之间β多样性的变化幅度较大，而在同一群落类型之间β多样性的变化幅度较小；② 随着距离差的增加，5种β多样性指数的变化趋势均说明距离差越大，群落之间的共有种越少，相异程度越大；③ 5种β多样性指数从两个不同的角度来测算，其结果具有一致性。其中，Bray-Curtis指数的测度结果更为准确和详尽。

Abstract: Mountain meadow is a kind of special ecosystem, it is not only a kind of important scenery resources, but also has certain ecological benefits. Many scholars studied the impact of tourist activities on meadow, but these researches were not still extensive and profound. In this paper, the impact of tourist activities on β diversity of meadow is studied using 5 indices in the Wutai Mountain. The results are as follows: (1) β diversity of meadow communities is impacted by tourist disturbance and interspecies competition. There is a big change of β diversity among different communities but a small one in the same communities; (2) The change trend of five diversity indices shows that the higher the distance gradient is, the less the common species among communities are, and the high their difference is; (3) Although five β diversity indices are calculated with different ways, their results are consistent, among which the result of BrayCurtis index is more accurate and detailed.

Key words: tourist disturbance, meadow community, inter species competition, &beta, diversity, the Wutai Mountain
