摘要	Lake level fluctuations of closed lakes in monsoonal regions are direct indicators of regional moisture variability related to the intensity of monsoon activities. In the current study, quartz OSL dating was applied to construct the chronology of two sedimentary sequences from the east and west shores of Huangqihai Lake in the East Asian monsoon area, and the history of lake level fluctuations during the late Quaternary was established. In the current study, we present field investigation findings of highstands of >87 m above the modern lake in enclosed Huangqihai Lake in northern China, and also use luminescence dating to establish the timing for the highstands. We conclude that: (1) Lake highstands occurred during both MIS 5 (>87 m above the modern lake) and early Holocene (similar to 9-8 ka, >54 m above the modern lake), (2) No highstands were observed for MIS 3 and MIS 2 during which loess has accumulated indicative of much drier climate; (3) The evolution of lakes in East Asian monsoon marginal area (e.g. Huangqihai Lake) is linked with the monsoon variation.
