中文摘要	中国北方沙漠,黄土高原和青藏高原是亚洲粉尘释放的关键区域,元素示踪研究表明中国西部沙漠和北部沙漠是亚洲粉尘和黄土高原黄土的主要源区.通过收集总结大量的大气观测,地球化学,地形数据,对比当前研究已得到粉尘的成果和释放模式,初步认为中国黄土物质来源于阿拉善高原的巴丹吉林沙漠与腾格里沙漠.这两个沙漠(包括阿拉善高原的戈壁)的源区是发育于祁连山北麓的弱水和石羊河山前冲洪积平原,近地面风是粉尘传输到阿拉善沙漠和中国黄土的主要动力.物质从发育于祁连山北麓的弱水,石羊河山前冲洪积平原到阿拉善高原沙漠最后到黄土的搬运方式可能是以一种接力棒的型式进行的
英文摘要	Deserts in northern China, Loess Plateau and Tibetan Plateau are the key dust release regions in Asian. Element tracer studies have shown that deserts of western China and northern China are the main source areas of Asian dust and Loess Plateau loess. Comparing with the obtained results and release mode of dust, the matter of Chinese loess is considered comes from Badain Jaran Desert and Tengger Desert of Alashan Plateau by collecting and summing up large amounts of atmospheric observation data, geochemical and terrain data. The source zone of these two deserts(including the Gobi Desert of Alashan Plateau) developed from the Ejin River of the northern foot of Qilian Mountain and the piedmont alluvial plain of Shiyang River, near-surface wind is the major driving force which propel dust to transfer to Alashan desert and Chinese loess. It is possible that it is a baton style way that the matter developed from the Ejin River of the northern foot of Qilian Mountain and the piedmont alluvial plain of Shiyang River transfer to desert of Alashan Plateau and then to loess
