Abstract

The formation of the complex linear dunes in the central Taklimakan Sand Sea is discussed based on analyses of wind regimes, sand grain size distributions on the topography of the dunes, and a contribution of geomorphic and geophysical investigations into the morphology of the dunes. Complex linear dune formation is shown to have 5 stages. Analysis clearly shows that under the control of wind regime, sand supply and other factors, the simple linear dunes move sideways while they evolve. This is the main cause for their formation. The evolutionary processes in this region partly support the theory of barchan evolution but do not support the roll-vortex and bimodal wind regime hypotheses
