摘　　要：灌丛沙堆是一种重要的风积地貌类型。在阐明灌丛沙堆分布规律、基本特征的基础上,着重论述了沙源、植被、风况等三个主要因素在灌丛沙堆地貌发育过程中所起的作用,总结了灌丛沙堆形成演化各阶段的地貌特征。随着灌丛沙堆地貌研究的不断深入,灌丛沙堆在土地荒漠化监测与评价、区域环境演变研究等方面的应用日益被国内外学者所关注。Nabkha is a kind of typical aeolian landforms. This paper reviewed overseas and domestic research achievements in distribution law, configuration characters, matter structure, type partition, and evolvement process about Nabkhas. At the base of setting forth the distribution law and essential characters of Nabkhas, this paper emphatically analyzed on functions of sand source, vegetation and wind regime in the process of Nabkha formation. Besides, the characters of landform in the formation phases of Nabkhas were summarized in the paper. With the development of research on Nabkhas, overseas and domestic researchers are paying more and more ＂attention to application of Nabkha research in monitoring and estimating soil desertification and regional environment evolvement.
