中文摘要	采用线路调查法研究了库姆塔格沙漠植物群落类型及植物物种多样性。结果表明,库姆塔格的植被可划分为山前戈壁荒漠植被、沙漠植被和荒漠草甸植被3大类型,其中沙漠南部山前戈壁的荒漠植被17类,沙漠东缘和北缘的荒漠草甸植被12类,沙漠植被13类。因分布区域的差异,不同植物群落的物种多样性存在一定差异,南缘戈壁荒漠植物群落较稳定,物种多样性水平高,多样性指数平均为1.437,均匀度和优势度指数分别为0.824和0.302;沙漠植物群落物种组成稀少,群落稳定性差,多样性指数平均为0.725,均匀度指数为0.533;盐化草甸类植物群落多样性水平不高,群落相对较稳定,多样性、均匀度、优势度指数分别为0.804、0.807、0.547。戈壁荒漠植物群落随着气候环境干旱程度的加剧,多样性水平趋于减少,北缘植物群落多样性在中部地段明显升高,这与土壤结构组成有必然的联系,两条经度线上植物群落多样性变化与区域地形地貌及水文条件具有密切的关系。
英文摘要	The line investigation method was used to study types and species diversities of desert plant communities in Kumutage Desert.The results indicated that there were three vegetation types in Kumutage desert,which were 1) the Gobi desert vegetation,including 17 desert plant communities distributed in front of the mountain in the south fringe of Kumutage Desert;2) the desert meadow vegetation,including 12 desert plant communities in the east and north fringe of Kumutage Desert;and 3) the sandy desert vegetation,including 13 desert plant communities.Species diversities of desert plant communities in different areas were varied due to the difference of their distribution areas.However,Gobi desert vegetation in the south fringe was steady with higher species diversity index(1.437) and homogeneity index(0.824),but the dominance index was lower(0.302).There were less species composition and poor community stability of sandy desert vegetation,which the average indices of diversity and homogeneity were 0.725 and 0.533.Species diversity of the desert meadow vegetation in the east and north fringe was not very high and community relatively steady,which the average indices of diversity,evenness and dominance were 0.804,0.807 and 0.547,respectively.With the drought intensification of climate and environment,the species diversity of Gobi desert vegetation tended to reduce,but the species diversity of desert meadow vegetation in the north fringe was significant higher than the central location caused by the different soil structure and composition.However,the factors,such as regional landform,geomorphy and hydrology,closely related to the diversity difference of desert plant communities of the two longitude lines.
