英文摘要Understanding the historical flooding regime and its driving mechanisms provide useful insights into prediction of disasters in future. In this study, the paleo-flooding activities along the upper Amur River Delta were reconstructed based on the grain-size dataset of three sedimentary cores along a 120-kmtransect fromits alluvial valley. Our results indicate that the coarse sand fraction in marshes surrounding the upper Amur River Delta is closely linked to historical flooding activities. Six "busy" flooding periods were identified at 4.4-4.0 ka BP, 3.63.2 ka BP, 1.7-1.4 ka BP, 1.1-0.9 ka BP, 0.7-0.5 ka BP, and 0.2-0 ka BP, respectively. These flooding intervals correspond well to other sedimentary flooding records from the East Asia Summer Monsoon (EASM) domain, and are in-line with the strengthened EASM stages throughout the Late-Holocene. Thus, our dataset suggests that the EASM circulation, especially its associated precipitation, has played a critical role in the evolution of flooding regime during the Late-Holocene epoch in the Amur River Delta. The last 0.2 ka BP is an exception as the coarse sand accumulation rate increased significantly while the EASM precipitation shows no equivalent shift. The increased coarse sand signals were likely attributed to floods induced by human interference instead of the long-term climate influence. (C) 2021 Elsevier B.V. All rights reserved.
