A Holocene loess-paleosol profile is studied on the river terraces, hills and plateau of the east piedmont of the Songshan Mountain in the upper reaches of the Yinghe River as a tributary of the Huaihe River. Higher resolution proxy data of magnetic susceptibility, particle-size distribution and >0.1mm grain-size percentage were obtained from the profile. The results indicate that the magnetic susceptibility of loess-soil sequences in the upper reaches of the Yinghe River was obviously lower than that on the Loess Plateau, but the grain-size was much coarser than that on the middle of the Loess Plateau. It revealed that they were from different dust sources, which belong to different dust transporting systems. On the deep analysis, it is revealed that the loess in the upper reaches of the Yinghe River was dust accumulation mainly from near source, while the coarser dust mainly come from the loose alluvial deposits of alluvial and proluvial fans of the Huanghe(Yellow) River to the east of Mengjin. A rich source of sandstorms were provided by the frequent breaching, diverging and flooding sediments of the Huanghe River. The north-east wind was the driving force of the sandstorm activity. During the late Holocene (3100-0 a B.P.) when the climate was tended to arid, the flooding frequency in the lower riches of the Huanghe River was increasing, the area of dust activity was extending and the sandstorm activity intensity was very strong.
