| 摘 要： | 自20世纪60年代至90年代，由于多种原因，辽东湾东西两侧的初始沙质海岸侵蚀范围逐年扩大，侵蚀不断加剧，给当人民的生产和生活带来严重危害。由多年监测资料发现，侵蚀严重的熊岳岸线以2～4m／a的速率而大幅度后退，特别严重的地区最大后退达10km；辽西绥中某些岸段平均每年后退1～2m。20世纪90年代后期，由于一些海域管理措施的出台和相应的海岸防护工程的建设，海岸侵蚀逐渐减弱。通过现场调查和多年监测，分析了辽东湾东西两侧砂质海岸侵蚀的特点，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，人为活动是关键因素，并提出了海岸侵蚀灾害的防治对策。

| Abstract: | From the 1960s to the 1990s, the erosional range of the east and west sandy coasts of Liaodong Bay was gradually expanded, and the coastal erosion was constantly aggravated, which made serious damage to the people's production and life. It is shown from the multi-year monitoring data in this area that the retreating rate of the heavily eroded Xiongyue coast was 2 m/a to 4 m/a with a maximum coastal retreation of 10 km in the extraordinarily eroded coast area; and the retreating rate in the Shuizhong area along the west coast of Liaodong Bay was 1 m/a to 2 m/a. In the late 1990s, the coastal erosion in this area was alleviated by taking some sea area management measures and constructing some associated coastal protection works. In this paper, based on the field investigation and multi-year monitoring data, the erosional features of the east and west coasts of Liaodong Bay are analyzed, and it is shown from the analysis results that the loose coast sediment composition and the strong coastal dynamic actions are the background for coastal erosion, but the human activities are the key factor for coastal erosion, and the prevention and control measures for coastal erosion disaster are also suggested. |
