中文摘要：

海滩状态是一个地形与水动力相互作用的三维地形动力问题。国外对海滩状态的地形动力分类已开展了大量卓有成效的研究工作,既包括波控、小潮、开阔海岸海滩状态的研究,也包括波控、不同潮差海岸海滩类型的研究和岬间海岸海滩类型的研究。文中回顾并概括了自20世纪70年代至今国外在砂质海滩地形动力分类方面代表性的研究工作,这些对于我国的海滩侵蚀过程和海滩资源的开发、利用与保护都具有重要的理论意义。

英文摘要：

Beach state is a three dimensional morphodynamic problem interacting between topography and hydrodynamics. There exists abundant fruitful literature about morphodynamic classification of beach state abroad, including microtidal sand beaches of open coast, as well as all wave-dominated beaches in all tidal ranges and beach types of headland-bay coasts. This paper reviews and generalizes representative researches on morphodynamic classification of sandy beaches since 1970, which would have important theoretical significance for beach erosion process study and beach resource exploitation, utilization and protection in China.
