| 摘 要： | 为了掌握绿洲荒漠过渡带天然植物群落结构及其多样性特征，为荒漠区植被恢复与多样性保护提供理论依据，通过野外实地调查，对腾格里沙漠东南缘绿洲荒漠过渡带白刺、猫头刺、油蒿3种天然群落结构特征及其多样性进行研究。结果表明：该区天然群落结构简单，组织水平低，群落中共有植物种29种，隶属10个科26个属，灌木层物种相对单一且数量较少，草本物种相对丰富且数量较大，植物都是以相对较低的芽位适应生境条件；天然群落丰富度指数较高，多样性指数较低，群落间的均匀度指数相差不大。本研究为当地生态环境建设和天然植被保护提供了一定的理论依据和参考价值。

| Abstract: | In order to grasp the community structure and diversity characteristic of the natural plant communities in oasis-desert transition area,to provide a theoretical basis for desert vegetation recovery and biodiversity conservation.The author researched Nitraria tangutorum,Oxytropis aciphylla and Artemisia desertorum of natural community ’ s structural characteristics and diversity in oasis desert ecotone in the southeast margin of the Tengger desert on the basic of the field investigation.The results showed:the structure of natural community was simple.It was composed of 29 plant species (26 genera,10 families).The shrub species was relatively homogeneous and small number,and the herbaceous species was relatively abundant and larger number.The plants were relatively low bud nodes to adapt to the habitat conditions.The richness index of natural community was higher,diversity index was lower,evenness index between the communities without big difference.The results could be the gist for the environment construction and the plant protection. |
