中文摘要	在2005年9月,对库姆塔格沙漠的梭梭沟区域(39°37′8~40°25′02N,92°12′59~92°46′27E)进行南北穿越,同时参考卫星照片和地形图,实地调查了库姆塔格沙漠的区域地貌形态。在纬向上,梭梭沟的沟头和沟尾分布有线形沙垄;沟谷区是沙垄相对高度最大的区域,也是沙丘类型最复杂的区域,复合型沙垄和综合型沙垄坐落在沟两侧的阶地上,沙丘类型有新月形沙丘链、金字塔型沙丘和波状线形沙垄,3条或4条小沙垄(链)组合成大沙垄,相对最大垄高为131 m。"羽毛状沙丘"分布在梭梭沟以北为冲洪积平原上,沙漠的北缘分布新月形沙丘,最高达26 m。在经向上,40%的相对应样点的风沙地貌类型不同。地貌差异性较大的区域分布在梭梭沟的形状变化较大的区域。梭梭沟的形状变化,影响其两岸的沙丘形态。流水构筑了库姆塔格沙漠的下伏地貌,风沙地貌的分布受流水地貌影响强烈。
英文摘要	In September of 2005,while we went across the Suosuo Ravine of the Kumtag Desert from south to north,the morphology of aeolian sediment landform was observed in the region of 39°37′8～40°25′02N,92°12′59～92°46′27E.The morphology is described by the observation in field and referencing to the photos and relief map of the Kumtag Desert in the paper.In the direction of latitude of the Kumtag Desert,the linear sandy ridge distributes at the head and the end of the Suosuo Ravine.The body of ravine is a place where the sandy ridge is relatively higher,and the type of sandy dune is complex too.The colligating sandy ridge or complex sandy ridge,that is,composed by 3 or 4 smaller ridges or chains,locates on the terraces of two sides of the body of the ravine,and there are some types of dunes with the relative height of 131 m which is the highest sandy dune at the two sides of the body of the ravine,such as crescentic dune chains,pyramid dune and wavy linear ridge.The like-feather sandy dune distributes in the middle-north of the desert,and the crescentic dune with the highest height of 26m is in the fringe of the desert.In the direction of longitude,40% of observed sample of morphology is different at parallelism position at the terraces of the ravine.The greater that Suosuo Ravine shape change is,the more different that landform is at the parallelism positions.The shape change of the ravine affects the shapes of dune on the two sides of the terrace of the ravine.The landforms were influenced by fluvial force around the dunes in the Kumtag Desert,which strongly affected type of dune and distribution of aeolian sediment landform in the regions of the desert.
