Abstract

Spatial and temporal distributions of dust fall along with the spatial variation of the biological crust were measured along a cross-section in China's Shapotou railway protective system. The variation of the aeolian environment was evident from the spatial variation of near-surface wind flow and both grain size and accumulation rate of dust fall. The surface conditions along the cross-section were characterized by crust type, crust thickness, and ground (0–5 cm) compaction. The distribution of dust fall and crust indicated the intensity of aeolian activity and the stability of the aeolian environment. Further improvement of the aeolian environment by natural processes or by human construction would promote additional dust fall and accelerate the development of the crust
