大都市海岸带生态整治修复技术研究进展与展望

受人类活动和自然灾害影响，大都市区海岸带生态环境遭到破坏，丧失了原有的生态服务功能。如何修复海岸带并发挥其支持作用成为沿海城市面临的重大问题与机遇。本文综述了近年来国内外以硬质岸线生态化、基底修复和海滩养护、水文调控、植被恢复以及牡蛎礁为代表的海岸带生态整治修复技术，并分析海岸带生态整治修复技术的发展趋势，认为需要充分考虑技术对海岸带特殊条件的适应性，注重研发人工干预与自然演替相结合的复合技术体系，相关技术还应当支持大都市海岸带生态系统功能和结构的提升以及景观尺度的复合生态系统的构建，进而能够提升海岸带生态环境质量，为市民提供亲近海洋、感受海洋的美丽海岸带。

Research progress and prospect of eco-realignment and restoration technologies for metropolitan coastal zone

Coastal regions as well as its ecosystem service now are under threaten by the combination effects of improper human activities and serious natural disasters. Restoring the damaged areas together with its services is both an opportunity and a challenge for coastal cities. Here, we summarized the representative coastal eco-realignment and restoration technologies including shorelines planting, sediment amendment and beach nourishment, hydrological control, marsh transplantation, and oyster reef construction. Moreover, we prospected the trends of coastal eco-realignment and restoration technologies, and suggested that studies should focuses on developing technologies that combining both human intervention and natural succession, in order to adapt to the harsh conditions at the coast. These technologies should also help to improve the function and structure of coastal ecosystems and to further form the landscape-scale composite ecosystems, which in turn improved the coastal environment and provided citizens with a beautiful habitat that could touch and explore the ocean.
