摘　　要：通过对巴丹吉林沙漠南部湖区湖滨带73个植物样方进行常规调查,结合野外实地考察和相关文献资料,对研究区植被特征(物种组成、植物频度、丰富度、区系成分和群落相似性系数)进行了探讨。结果表明:研究区共有植物种9科30属31种,白刺、芦苇、芨芨草、甘草出现频率最高;植物丰富度随海拔高度的增加呈波动型变化;调查到的植物按区系地理成分归为7个大类,以亚洲中部分布种和古地中海分布种居多;植物群落间物种组成差异较大,群落相似性系数(Jaccard相似性系数)平均为0.21。Based on a routine survey of 73 plant quadrats in the lakeside zone of the southern lake of the Badain Jaran Desert,combined with field investigation and related literature,vegetation characteristics(species composition,plant frequency,richness,floristic composition and community similarity coefficient)in the study area were discussed.A total of 31 species,30 genera and 9 families were found.Nitraria roborowskii,Phragmites australis,Achnatherum splendens and Glycyrrhiza uralensis appeared most frequently.The plant richness fluctuated with the increase of altitude.According to the floristic and geographical composition,the investigated plants were divided into 7 groups,most of which were distributed in Central Asia and Paleo-Mediterranean.The community similarity coefficient(Jaccard similarity coefficient)was 0.21 on average.
