中文摘要	为进一步探讨新疆维吾尔自治区北山库姆塔格地区沙漠成因和保护生态环境提供依据,分析了该区沙垄的形态特征。对库姆塔格沙垄地区的ETM遥感图像裁剪出相对应的沙丘形态类型图像,并进行锐化增强处理;基于SRTM数据,通过ArcGIS软件的三维分析模块得出库姆塔格沙垄的高程图;根据当地的地形地貌特点绘制简易的主风向图;详细分析每种类型沙丘的特征。研究表明:库姆塔格沙垄由于其独特的自然地理特点,形成狭长的"S"型沙垄,沙丘形态复杂多样;该区沙丘类型主要以新月形沙丘链和复合型纵向沙垄为主,单个新月形沙丘较零散,线性沙丘分布较少,树枝状沙丘还处于雏形。
英文摘要	The purpose of this study is to provide the basis for further study of desertification origin and the protection of ecological environment in this region. The morphological characteristics of Kumtagh sand dunes in Beishan of Xinjiang Uygur Autonomous Region were analyzed, the Landsat ETM images of morphotype of Kumtagh sand dunes were cut out, and the sharp images were also enhanced. On the basis of SRTM data,the digital elevation mode for Kumtagh sand dunes were obtained by means of three-dimensional analysis module of ArcGIS software. Simple wind figures were drawn according to the local terrain and physiognomic characteristics. The characteristics of each type of sand dune were analyzed in detail. This study results that sand dunes in Kumtagh form a long and narrow "S" shaped ridge due to the unique natural geographic features,and the dune morphology is diverse and complex. The main types of sand dunes are crescent dune chains and complex longitudinal sand dunes. The single crescent dunes are scattered, the linear dunes are less distributed,and the dendrite dunes are in the early development stage.
