Abstract

In this study, 263 samples were taken from the section for grain-size analysis, 25 for chemical analysis, ii for C 14 dating and 6 for scanning electron microscope (SEM). The results indicate that 3 types of the sediments in the section can be identified. The Ejin Section has recorded the repeated dust-storms or sandstorms since 2500 yr BP and these peak periods are consistent with the records of dust rains in historical literatures, indicating that the change of climate is a key factor to increase sandstorms or dust-storms, whreas, artificial factor may only be an accelerating one for desertification
