英文摘要Deserts are widely distributed in northwestern China in a wide range of geomorphological and tectonic settings, from 155 m below sea level to more than 5000 m above sea level (asl.). In this paper the author briefly reviewed some of the recent studies aiming to understand the formation and changes of the sand seas in northwestern China. Loess sequences in Loess Plateau indicated that deserts in western China may have existed already 22 Myr ago, but geomorphological and sedimentological evidence found in the deserts suggests a much younger age. The geomorphological link between the Tertiary deserts and the present-day ones is not yet understood. In many parts of the deserts in northwestern China, late Pleistocene or even Holocene lacustrine and fluvial sediments are buried under the dunes, showing abrupt Late Quaternary environmental changes in the dune areas. Although the mechanisms for the formation of the megadunes in the Badain Jaran Desert are controversially argued in various publications - landforms control vs. groundwater control - geomorphological investigations are essential in order to solve this dispute. It is envisaged that geomorphology would be really crucial to the development of the Earth system sciences, dunes representing significant information archives for understanding the Earth system.
