英文摘要	A large area of moraine sediments and cryogenic weathering products, formed by glacial action and a cold environment, are the main source of aeolian sand in the high and cold region of the Qinghai-Tibetan Plateau in China. The evolution of aeolian dunes is closely related to the periglacial environment. Owing to the freezing of dune-land surfaces, the evolution of sand dunes is dominated by expanding dune bases and vertical accretion, thereby forming large barchan dunes. The migration rates of these large barchan dunes are very slow at an average rate of 1.7-0.7 cm center dot a(-1). The temperature mainly controls the environmental changes in the adjoining region of Puruogangri ice sheet. The C-14 dating of humus layers in the studied area of the sand dune are 10,780 +/- 130, 9,549 +/- 1130, 8,320 +/- 110, 7,450 +/- 100, 5,970 +/- 95, 5,330 +/- 90, 4,420 +/- 80, 3,460 +/- 80, 2,280 +/- 170, 980 +/- 70 aBP, respectively. The region's high temperature rising up during summer from the southwest monsoon intensity might be an important factor. As long as both water and temperature conditions are suitable, the plants will grow well, sand dunes will be stabilized, forming humus layers. Otherwise, sand dunes are bare and re-activate.
