摘　　要：通过不同时期海图对比、分析遥感图像和多年现场监测资料,分析了辽东湾绥中沙质海岸侵蚀的特点,认为海岸组成物质松散与海岸动力作用强烈是本区现代海岸侵蚀的基本条件;陆源物质入海量减少、海动力作用、沿岸工程建筑和海上采砂是其海岸蚀退的主要影响因素。In this paper, the erosional characteristics along the Suizhong sandy coast of the Liaodong Bay are analyzed by comparing nautical charts in different periods and analyzing remote sensing images and multi-year field monitoring data, and it is shown from the analysis results that the loose coastal sediments and intense coastal dynamic actions are the basic conditions for the recent coastal erosion, and the decrease in terrigenous material discharged into the sea, marine dynamic actions, coastal engineering structures and offshore sand recovery are the main affecting factors for the coastal retrogradation.
