大坂山不同海拔高寒植被物种多样性研究
Study on Species Diversity of Alpine Vegetation with Different Altitudes in Daban Mountain
摘要
Abstract
[ 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 ( 3025 m, 3405m, 3813 m ) 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.关键词
