摘　　要：海岸线的时空演变是海洋经济发展的重要记录,研究区域海岸线时空演变,分析其演变驱动力对于区域海岸带发展及管控具有重要意义。本文利用1973—2023年多期卫星影像对威海湾海岸线的时空变化进行了分析,结果显示,1973—2023年,威海湾海岸线总长度共增加14.4 km,其中人工海岸增加31.4 km,增量最多,增速在1990—2015年达到最大。未来威海湾近岸区域开发利用时,应严格保持目前岸线走向形态,保护海岸格局不受破坏,依托岸线形态规划陆上景观,强化海岸带分段指引,集约高效利用海岸线,使威海湾宝贵的岸线资源成为威海市“精致城市”发展的重要支撑。The spatiotemporal evolution of coastline is an important record of the development of marine economy.Studying the spatiotemporal evolution of regional coastline and analyzing its driving forces is of great significance for the development and management of regional coastal zones.In this paper,by using multiple satellite images from 1973 to 2023,spatiotemporal changes of the coastline in Weihai Bay have been studied,and the driving forces of coastline changes have been analyzed.It is showed that the total length of the coastline in Weihai Bay has increased by 14.4km from 1973 to 2023.Among them,the artificial coastline has increased 31.4km with the largest increasing amount,and the growth rate has reached its peak from 1990 to 2015.In the future development and utilization of the nearshore area of Weihai Bay,it is necessary to strictly maintain the current shoreline direction and protect the coastal pattern from damage.Based on the shoreline form,the land-based landscape should be planned,the coastal zone segmentation guidance should be strengthened,and the coastline should be intensively and efficiently utilized.It will make the precious shoreline resources of Weihai Bay as an important support for the development of"exquisite city"for Weihai city.
