Abstract: Northwestern China is the region with high frequent dust storms in the world, and the dust storms have been the serious disaster in the region. It was firstly discovered that deposit records of dust storm during Early Holocene in the investigation into lake sediments in the Hexi Corridor. Yema Lake section located in the terminal area of the Shiyang River Drainage of eastern Hexi Corridor, Northwestern China, recorded rich information of the lake evolution and climatic change since Holocene. Many interlayers of rapid aeolian coarse silt and fine sand were documented in between the lacustrine sediment, and were considered as transport and deposit of rapid dust storms. Furthermore, analysis of grain size, micro-shape of quartz sand, magnetic susceptibility and organic carbon revealed the coarse silt and fine sand layers were same as modern dust storm deposit with rapid short-haul transporting trait, but different from active dune sand deposit.According to interpolation of the ¹⁴C ages of different depth, age sequence of Yema Lake section was established, and lake evolution and climatic change in the Shiyang River Drainage were reconstructed. The result showed that dust storm events had occurred with 400a quasiperiod during Early Holocene(10 000-6 700 a B.P.), the wettest climate phase. The dust storm events occurred in the Shiyang River Drainage during Early Holocene were natural phenomenon relating with regional environment of Northwestern China.
