摘  要：
通过对库姆塔格沙漠的实地观测、样品分析和资料收集,获得了沙漠地区的基础数据。沙漠面积约2.29×104km2(2001年),沙漠存在向东南方向移动和周边扩大的趋势;库姆塔格沙漠沙丘形态以新月形沙丘链为主,羽毛状沙丘为特色,星状和其他复合型沙丘大量分布的特点;羽毛状沙丘的"羽轴"是一种较特殊的复合型沙垄,由单个新月形沙丘前后相连,在沙垄和沙垄之间的沙平地有地形起伏,形成较宽大的弧形沙埂,基本与沙垄走向垂直,由这些沙垄和沙埂组成了独特的羽毛状沙丘;沙漠内部羽毛状沙丘分布区全年盛行东北风,全年平均风速5.94m/s,年总输沙势944.46 VU;调查记录了沙漠区107种植物和79种脊椎动物,发现野骆驼在沙漠西部的水源地,3种稀有荒漠植物的新分布区;提出沙漠最早形成于70万年的中更新世。

摘  要：
The Kumtag Desert is the sixth largest desert in China.In this study,basic data regarding this desert and some new findings based on comprehensive scientific investigation and the results of field observation,sampling analysis and data collection are presented.The area of the desert was approximately 2.29×104 km2 in 2001,and it tends to be progressing southeastward through peripheral expansion.Morphologically,Barchan chains are dominant in the Kumtag Desert,followed by featherlike longitudinal ridges,pyramid dunes and complex dunes.The "axis" of featherlike longitudinal ridges is a complex type of dune ridge.Barchan dunes in the region connect one after another,and there is a hypsography in the zones between dune ridges.Additionally,there are some camber sand ridges that have formed vertically to the main dune ridges.All of the sand ridges form special featherlike longitudinal ridges.In areas with the special featherlike longitudinal ridges,the prevailing wind is northeast year round,the annual average wind speed is 5.94 m·s-1,and the total sediment transport potential is 944.46 VU.In the present study,107 plant species and 79 invertebrate species were identified.Furthermore,drinking water sources utilized by wild camels in the western portion of the desert were identified.Moreover,camels were found to migrate seasonally to different steppes in the desert.Additionally,several new distribution areas of rare desert plants were identified.Finally,the results of this study demonstrated that the desert formed in the mid-Pleistocene Period,7.0×105 years ago.
