摘  要：
为了探明辽东半岛海岸侵蚀的分布规律和发育特征,结合海岸侵蚀的现场调查资料,对辽东半岛海岸蚀淤状况和侵蚀发育特征进行了研究。结果表明,辽东半岛海岸可划分为严重侵蚀、强侵蚀、侵蚀、微侵蚀、稳定共5种侵蚀等级。其中,沙质海岸侵蚀较重的区域主要分布在绥中和鲅鱼圈一带,基岩海岸侵蚀较重的区域主要分布在大连金石滩一带,粉沙淤泥质海岸侵蚀较重的区域分布在庄河一带。河流入海泥沙的减少是近年来辽东半岛海岸侵蚀的主要原因,气候变暖引起的海平面上升对辽东半岛海岸侵蚀起一定的控制作用。此外,人为采砂和不合理的海岸工程进一步加剧了局部海岸侵蚀的程度。

摘  要：
To identify distribution and development of coast erosion in the Liaodong Peninsula,the development characterietics of erosion and siltation are studied based on the data from field investigation.Results show that coast erosion in the Liaodong Peninsula can be divided into five grades of serious erosion,intensive erosion,erosion,micro-erosion and stability.The sandy coast in Suizhong and Bayuquan area,rocky coast in Jinshitan area and silt-muddy coast in Zhuanghe area have been eroded seriously.Moreover,developmental characteristics and formation causes of coast erosion in typical coastal zone of Liaodong Peninsula are evaluated.The typical coastal zone is important to erosion control and management in a coastal zone.Recently,the decrease of river sediment into sea is the main reason for coastal erosion of Liaodong Peninsula,and sea level rise caused by climate warming plays a controlling role on coastal erosion.In addition,sand excavation and unreasonable coastal engineering have further intensified the degree of local coastal erosion.
