P512.2; The dust source and transporting system are two indispensable aspects in the process of loess-palaeosol accumulation. It has been proved that the dust of the Loess Pla-teau mainly comes from the northwestern inland gobi and desert, transported by the East Asia monsoon systems and westerlies. However, there are little researches with respect to the dust source and deposition dynamics of the upper reaches of the Huaihe River. In the present study, we investigated and collected the YPC section with high resolution in the upper reaches of the Huaihe River. The chronological frame was reconstructed by optically stimu-lated luminescence(OSL)dating and correlated with the published loess time series. By comparison of the magnetic susceptibility(MS)and grain size(GS)of loess-soil profile among YPC profile, XJN profile(western Loess Plateau)and the JYC profile(southern Loess Pla-teau), we find sirnilar climate change and pedogenic process between the upper reaches of the Huaihe River and the Loess Plateau, bot
