摘　　要：杭州湾南岸是我国近代海岸线变化最大的海岸带之一。前人曾利用史料、遥感、土地利用等手段对这一带岸线的变化进行过大量的研究。最近,笔者等在慈溪市滨海平原中距海岸线2~3 km的二座孤山—伏龙山和海王山发现了海蚀崖、海蚀沟、海蚀穴等海蚀地貌,从而提供了对历史海岸线位置有明确指示意义的地质地貌证据。分析认为此乃20世纪60年代的海岸线位置所在。此发现不仅对杭州湾地区的岸线变化、人类活动对滩涂改造等研究具有重要的价值,同时,这也是杭州湾地区难得的历史海岸线地质遗迹,对开展科普宣传、研学旅行、地学旅游等具有重要意义。The South Shore of Hangzhou Bay is one of the most changeful sections in China’s coastline since modern era.In previous studies,researchers have conducted much investigations using historical record,remote sensing data and land use planning in this region.Recently,our investigations in the area have discovered wave-cut cliffs,grooves and caves near two isolated hills 2~3 km away from the coastline of Cixi City’s coastal plain,the Fulong Mount and the Haiwang Mount,which are direct geological and landscape evidence providing explicit indicative implications on location of historic coastline.Analysis suggests that these marine abrasion landforms are remains of former coastline in 1960s.Our discovery has important significance on shoreline variation studies and human influences on intertidal zone’s evolution,meanwhile,these wave-cut landscapes are also very valuable geological relics of historical shoreline of Hangzhou Bay that can serve well on popular science propaganda,study tours and geological tourism.
