中文摘要	腾格里沙漠植被在维持沙漠生态系统稳定、促进生物多样保护及防风固沙等方面发挥着极其重要作用。在实地调查和查阅资料的基础上,划分了腾格里沙漠植被类型,分析了典型植物群落数量特征。结果表明:(1)腾格里沙漠植被类型较多,有6个植被型组、17个植被(亚)型、35个植被群系,具有典型的荒漠化草原植被特征。植被空间分布差异明显,南部流沙分布较广,植被类型单一,北部戈壁与沙漠交错分布,植被类型及物种组成相对丰富。(2)腾格里沙漠共有天然种子植物60科201属382种,多年生草本、一年生草本和灌木分别占总物种数的44.50%、 25.92%和21.99%,乔木、寄生草本和水生草本数量较少。(3)腾格里沙漠典型灌木群落中,一年生草本占有较大比例,多年生草本次之,灌木所占比例相对较小,灌木常为群落优势种,属于群落稳定层片,而一年生草本数量随降雨变化较大,属于不稳定层片。(4)群落多样性南北差异较大,沙漠南部群落物种组成相对单一,物种丰富度、Simpson指数、Shanon-wiener指数、种间相遇率相对较低,沙漠北部群落物种组成丰富,多样性指数高,生态优势度不明显。
英文摘要	Vegetation played an important role in maintaining the ecosystem stability,promoting biodiversity conservation,windbreak and sand fixation in the Tengger desert. On the basis of field investigation and consulting data,vegetation types were divided,and quantitative characteristics of typical plant communities were analyzed. The results showed that:(1)There were abundant vegetation types in the Tengger desert,including 6 vegetation type groups,17 vegetation(sub)types and 35 vegetation groups,which had typical vegetation characteristics of desertification grassland. The spatial distribution of vegetation was obviously different in the Tengger desert. The quicksand was widely distributed in the south,the vegetation type was single,while the Gobi and desert were crisscross distributed in the north,and the vegetation type and species composition were relatively rich. (2)There were 382 species of natural seed plants belonging to 201 genera,60 families in the Tengger desert. Perennial herbs,annual herbs and shrubs accounted for 44.50%,25.92% and 21.99% of the total species, and the number of arbors,parasitic herbs and aquatic herbs was small. (3)In typical shrub communities in the Tengger desert,annual herbs accounted for a large proportion,followed by perennial herbs,and shrubs accounted for a relatively small proportion. Shrubs were often the dominant species and belonged to stable layers in the community,while the number of annual herbs varied with rainfall and belonged to unstable layer.(4)The community diversity varies greatly from north to south. The species composition of the community in the south of the desert is relatively single,and the species richness,Simpson index,Shanon Wiener index and interspecific encounter rate are relatively low. The species composition of the community in the north of the desert is rich,the diversity index is high,and the ecological dominance is not obvious.
