Description :
Spatial and temporal patterns of aeolian deposition at Shapotou, northern China, were studied on a chronosequence (0,12,29 and 37 years) of stabilised desert dunes. Aeolian deposition markedly influenced soil and vegetation changes on the dunes. Mean deposition from August 1993 to July 1994 showed a complex spatial pattern, determined by prevailing wind direction, topography and shrub distribution. The implications of projected increases in the dustiness of arid regions on the stability of desert dunes and vegetated desert margins are discussed.
