| 摘 要： | 海滩地形动力分类在国外的海岸地貌研究中已经被广泛接受。本文使用了华南粤西水东湾切线带、过渡带和遮蔽带海滩连续16个月32次大潮期间同步获取的波浪、潮汐、泥沙和海滩地形数据，分别按照无量纲沉降参数、相对潮差参数和无量纲海湾尺度参数对这一岬湾海滩不同岸段的海滩类型进行了研究，研究发现：（1）水东湾切线带海滩的主要状态为有裂流的低潮台地状态和沙坝型海滩状态，过渡带海滩主要状态是低潮沙坝/裂流海滩和沙坝消散型状态，遮蔽带海滩主要状态是有或无沙坝的消散型状态；（2）海湾不同岸段海滩状态的顺序变化与差异体现了岬湾海滩状态的时空变化性，与现场观测的海滩地形的变化基本一致，说明了对波控中到强潮海滩进行研究时，需要考虑潮汐的影响。同时，本文主要给出了海滩状态研究的一个框架体系，由于海滩不同的状态伴随不同的侵蚀模式，要求我国今后需加强在这一方面研究，以进一步丰富我国海滩地形演变、海滩地形动力过程和海滩防侵蚀的理论基础。

| Abstract: | Beach morphodynamic classifications have achieved extensive acceptance in foreign coastal geomorphological studies. Three beaches located in different zones of a headland-bay coast are classified according to a dimensionless fall parameter, a relative tide range parameter and a dimensionless embayment scaling parameter. Synchronous data, including wave, tide, sediment and beach morphology, are respectively collected from the tangential beach, the transitional beach and the shadow beach of the Shuidong Bay during each spring tide for 16 successive months. The research results indicate that (1) the beach in the tangential zone falls between two major categories which are low tide terrace beaches with rips and barred beaches; the beach in the transitional zone exhibits two main types which are low tide bar/rip beaches and barred dissipative beaches; and the beach in the shadow zone mainly mirrors dissipative states with presence or absence of bars; and (2) the sequential changes and differences of beach states in different coastal zones reflect spatial and temporal variabilities of the headlandbay coast, totally meeting the actual measured beach morphology changes, showing that studies on wavedominated, meso-macrotidal beaches need to consider the influences of the tides. Meanwhile, the research mainly provides a framework about beach state studies, due to different beach states with different erosion patterns, which requires the need to strengthen the researches in this respect, in order to further enrich theoretical basis for a beach topography evolution, beach morphodynamic processes and beach erosion prevention in China. |
