颍河下游商朝初期古洪水事件考证及河道演化研究

A Textual Research on the Ancient Flood Events in the Lower Reaches of Yinghe River during Early Shang Dynasty

作为著名的“四渎八流”之一,颍河洪涝灾害研究是透视黄淮流域灾害史的重要窗口。文章以颍河下游杨湖镇河流阶地留存的古洪水滞留沉积物记录为切入点,全面梳理了黄淮流域商朝初期洪涝灾害史料,重点对古洪水事件的发生年代进行了考证,研究发现古洪水滞留沉积物所记录的古洪水事件可能是发生于仲丁六年(前1557)的一次特大洪涝灾害。依据洪泛沉积物磁组构的古流向重建结果推测,颍河下游河道经历约3500年的演化后,阜阳至入淮口段河道长度增长约33 km。

As one of the famous“Four rivers and eight Streams”,the study of Yinghe River flood disaster is an important window to disclose the history of disasters in the Huang-Huai River Basin.Taking the sediment records of ancient flood retained on the river terrace of Yanghu Town in the lower reaches of Yinghe River as the entry point,this paper comprehensively sorted out the historical materials of flood disasters in the Huang-Huai River basin in the early Shang Dynasty,focusing on the research of the occurrence time of ancient flood events.It was found that the paleo-flood event recorded in the sediments of the paleo-flood may be a great flood disaster that occurred in the sixth year of Zhongding(1557 BC).After the evolution of the lower reaches of Yinghe River for about 3500 years,the length of the channel from Fuyang to the Huaihe estuary increased by about 33 km.
