摘要:

海岸带作为海陆缓冲地带，长久以来发挥着保护陆域免受海洋灾害影响的重要作用。在遭受灾害带来的外界干扰时(例如风暴、海平面上升、海岸线侵蚀等)，海岸带系统具备抵抗、恢复及适应该负面影响的能力，这种与变化环境相适应的能力被称为海岸带韧性。然而人类文明发展以来，长期大规模的干扰活动削弱了海岸带韧性，破坏了海岸带动态演变过程中动力地貌的平衡。因此，本文从海岸带地貌演变的特征展开，总结现有的海岸带侵蚀机理研究成果，指出研究方法中存在的问题和不足，并对目前热点的海岸带韧性与灾后恢复机理研究进展进行梳理，同时结合近年来新兴研究方向指出现有研究内容的不足之处，最后展望了“海洋十年行动计划”背景下海岸带综合开发与管理的研究趋势。

Abstract:

As a sea-land buffer zone,the coastal zone has played an important role in protecting land from marine disasters for a long time.When suffering from external disturbances caused by disasters (such as storms,rising sea levels,coastline erosion,etc.),the coastal zone system has the ability to resist,restore and adapt to this negative impact.This ability to adapt to the changing environment is called coastal zone resilience.However,since the development of human civilization,long-term large-scale disturbance activities have weakened the resilience of the coastal zone and destroyed the balance of dynamic landform in the dynamic evolution of the coastal zone.Therefore,this article starts from the characteristics of coastal morphology evolution,summarizes the existing research results of coastal erosion mechanism,points out the problems and shortcomings in the research methods,and sorts out the current research progress of coastal zone resilience and post-disaster recovery mechanism.At the same time,combined with the emerging research directions in recent years,the shortcomings of the existing research contents are pointed out.Finally,the research trend of comprehensive development and management of coastal zones under the background of the “Decade of the Oceans Plan” is prospected.
