[目的]研究大坂山不同海拔地区高寒植被的物种多样性.[方法]对祁连山山脉东段大坂山高、中、低(3025、3405、3813 m)3个不同海拔的植物群落进行调查,并比较分析了3个不同海拔高度植被的丰富度、多样性指数.[结果]随着海拔的逐渐升高,其植物丰富度逐渐减小;植物群落物种多样性在中海拔相对较低;群落相似性随着海拔的升高而降低,群落的β多样性具有明显的变化.[结论]海拔梯度造成的环境因子的变化以及人类干扰是造成不同海拔高度物种分布格局发生变化的重要原因.

[Objective] The aim of this study is to investigate species diversity of alpine vegetation in different altitudes of Daban mountain. [Method] Plant communities were surveyed in three different altitudes (3025m,3405m,3813m) of Daban mountain, the eastern Qilian, and the richness or diversity index of vegetation in three different altitudes was comparatively analyzed. [Result] The species richness decreased with the gradual increase of altitude, and species diversity of plant communities was relatively lower in medium altitude. Furthermore, community similarity also decreased with the increase of altitude, and β diversity of communities had a significant change. [Conclusion] Environmental factor change caused by different altitudes and human disturbance are important reasons for the change of species distribution pattern in different altitudes.
