摘　　要：受黄河入海流路变迁和入海泥沙锐减的影响,近年来黄河三角洲岸线冲淤变化复杂。本研究基于Landsat遥感影像,提取2000—2020年黄河三角洲的年平均岸线,分析其岸线冲淤变化。结果显示,北部岸段和原清水沟入海水道岸段岸线呈现蚀退作用,现清八汊入海水道岸线呈现淤积作用。Influenced by the change of the Yellow River′s flow path into the sea and the sharp decrease of sedi-ment entering the sea,the shoreline siltation change of the Yellow River Delta shoreline has been complicated in re-cent years.Based on Landsat images,this study extracts the annual average shoreline of the Yellow River Delta from 2000 to 2020 and analyzes the changes of shoreline siltation.The results show that the shoreline of the northern shore section and the former Qingshui Gully inlet channel shows erosion and retreat,and the shoreline of the present Qing-bacha inlet channel shows siltation.
