摘　　要：大沙鼠活动影响植物群落结构和物种组成,号称“生态系统工程师”。为探究大沙鼠活动对民勤荒漠区人工梭梭林的群落效应,调查比较了大沙鼠洞区与无洞区植物种类、个体数量、高度的差异。结果表明:大沙鼠活动可以增加人工梭梭林草本植物种类数量,导致灌木种类消退,促进雾冰藜、沙米、猪毛菜分布,减少霸王和芦苇分布;不影响灌木高,降低草本植物高度。The activities of Rhombomys opimus affect the structure and species composition of plant communities and are known as"ecosystem engineers".In order to explore the community effect of R.opimus activity on artificial Haloxylon ammodendron forest in Minqin desert area,the differences of plant species,individual number and height between R.opimus cave area and non-cave area were investigated and compared.The results showed that the activity of R.opimus could increase the number of herb species in the artificial H.ammodendron forest,lead to the decline of shrub species,promote the distribution of Grubovia dasyphylla,Agriophyllum squarrosum,Kali collina,and reduce the distribution of Zygophyllum xanthoxylum and Phragmites australis;It does not affect the height of shrubs,and the height of grass decreases.
