摘要
海岸是滨海旅游的重要资源,海岸线变化会对滨海发展产生较大影响.对东海岛龙海天沙滩进行卫星遥感影像及沙滩剖面实地测量分析,以探究20年来的海岸线变化.结果表明,该处海岸线2000—2013年整体向海一侧推移,2013—2020年缓慢向陆推移.在季节上,从春到冬,沙滩剖面的变化呈“堆积—侵蚀—局部侵蚀—局部堆积”的规律.海平面变动、季节风向转变和浪潮作用是其变化的主要驱动因素.
The coast is an important resource of coastal tourism,and coastline change will have a large impact on coastal development.Satellite images and beach profile of Longhaitian Beach in Donghai Island were measured and analyzed to explore the coastline change in the past 20 years.The results show that the coastline of this area moved toward the sea as a whole from 2000 to 2013,and slowly moved toward the land from 2013 to 2020.From spring to winter,the variation of beach profile shows the law of“accumulation-erosion-local erosion-local accumulation”.Sea level change,seasonal wind direction change and tidal wave action are the main driving factors of its variability.
