摘要

The Horqin dunefield is located in the northern frontier of East Asian Monsoon(EAM) zone, and its activation and stabilization is sensitive to the ebb and flow of the EAM. However, the activity of dunes in the Horqin dunefield is still poorly understood due to the limited numerical dating. The purpose of the present study is to explore the dune evolution using luminescence dating and pollen analysis in order to understand the relative role of climate and human activity. In the present study, 21 samples collected from seven sections in the Horqin dunefield were dated using quartz optically stimulated luminescence (OSL) dating method.
