中文摘要	以1∶ 500 000地质图为基础,利用Map GIS对柴达木盆地进行数字化。根据Google Earth的卫星图和Google Maps的地形图,结合野外考察,进行柴达木盆地现代沙漠范围的勾画。从数字化的地质图中提取盆地内全新统(Q_h)和上更新统(Q_3)的风成堆积层,结合已有文献资料,绘制出全新世大暖期和末次盛冰期盆地内沙漠的分布图。特征时期沙漠分布图显示,全新世大暖期盆地内沙漠范围大大收缩,比现代沙漠范围小,对暖湿的气候有着很好的响应; 末次盛冰期盆地内沙漠范围迅速扩张,比现代沙漠范围大,对干冷的气候有着很好的响应。
英文摘要	Based on a geological map with measuring scale of 1∶ 500 000,the Qaidam Basin was digitized using MapGIS. According to the satellite images of Google Earth and topographic map of Google Maps as well as the field investigation,in this paper the distribution of modern sand desert in the Qaidam Basin was delimited. The aeolian accumulative formations of Holocene and Late Pleistocene were extracted from the digital geological map of the basin based on the available literatures,and then the maps of distribution of the desert during the Holocene Megathermal Period and the Last Glacial Maximum were sketched out. According to the distribution maps of the desert,the scope of the desert during the Holocene Megathermal Period contracted and was smaller than that of the modern one in the basin,and the desert responded well to the warm-humid climate. While the scope of the desert during the Last Glacial Maximum expanded rapidly and was larger than that of the modern one in the basin,and the desert responded well to the dry-cold climate.
