库姆塔格沙漠位于塔里木盆地罗布泊南缘，南以阿尔金山为界，北以阿其克河谷为界，东至甘肃省东黄市，面积2.29×10~ 4km 2，是我国第六大沙漠。库木塔格沙漠具有沙丘流动快，沙丘覆盖地貌复杂，极端干旱的气候条件和连续出露的地层，蕴含着记录库姆塔格沙漠形成和演化的大量信息，气候变化和疏勒河古水系的变迁，开展综合调查对研究库姆塔格沙漠的形成和演化具有重要意义，疏勒河古水系的变迁及其与罗布泊萎缩的关系，努尔。也有助于了解西北地区气候环境变化对青藏高原强烈隆升和全球变化的响应机制，此外，对研究库姆塔格沙漠风沙活动和风沙危害，了解野生动植物的分布和习性，保护东荒自然文化遗产和干旱荒漠生态系统的生物多样性，具有重要的现实意义。
Kumtag desert in the south margin of Lop-Nur area of Tarim basin is bound by Altun Mountains in south and Aqik Valley in north,and reaches eastward Donghuang city of Gansu,covering an area of 2.29×10~4 km~2.Kumtag desert is the sixth biggest desert in China.In investigation we found that there are many types of sand dunes,including the unique plumed dunes in the world.Kumtag desert are characterized by the quick mobility of sand dunes,the complicated dune-covered-landform,the extremely arid climate conditions and the sequential exposed strata which contain large numbers of information of memorizing the formation and evolution of Kumtag desert,climate change and the vicissitude of ancient drainage system of Shulehe River.To conduct integrated investigation is very significant to study the formation and evolution of Kumtag desert,the vicissitude of ancient drainage system of Shulehe River and the relationship with the shrink of Lop-Nur.It is also helpful to understand the response mechanism of climate and environmental changes in Northwest China to strong uplift of Qinghai-Xizang Plateau and global change.In addition,it has the realistic significance to study the blown sand activities and blown sand hazard of Kumtag desert,to find out the distribution and habit of wild animals and plants,and to protect the natural and cultural heritage of Donghuang and the bio-diversity in arid desert ecosystem.
