摘要: The palaeoshorelines of a lake are the direct geomorphic evidences to reflect past water levels and record information on palaeoclimatic changes. Previous research indicates that timing forcing mechanisms climatic change northeastern Qinghai-Tibetan Plateau (NE QTP) still controversial. Here, we report quartz optically stimulated luminescence (OSL) ages for beach deposits accelerator mass spectrometry (AMS) 14C age plant remains, shoreline features exposures contribute reconstruction lake-level history Hurleg Lake NE QTP. results imply (1) three high dated 6.8–6.4, 5.0–4.7 2.2–1.4 kyr, corresponding relatively wet stable climate from pollen records sediment core in this during mid–late Holocene; (2) highest period occurred at which is almost synchronous with effective moisture phase synthesized influenced by Westerlies (3) ...
