在研究了海南岛石梅湾风、浪、流等动力条件的基础上，指出了石梅湾的海滩与海岸是海洋动力与沉积物相互适应的产物，目前已达动态平衡。风浪作用对海滩发育有重要影响，风暴剖面与涌浪剖面的交替具有重要意义。而石梅湾海滩韵律地形的沿岸移动是局部海滩严重侵蚀的真正原因，海面上升仅会导致普遍意义的海滩侵蚀。人类活动对石梅湾海滩的演变有重要意义。
On the basis of studying the dynamic conditions such as the wind, waves and currents in Shimei Bay of Hainan Island, it is pointed out that the beaches and coasts of Shimei Bay are the products of mutual adaptation of marine motive force and sediment, and have reached the dynamic equilibrium at present. The effects of storms have an important impact on beach development. The alternation of storms and surges is of great significance. The coastal movement of the prosperous topography of Shimei Bay Beach is the real cause of the serious erosion of local beaches. The rise of the sea surface will only lead to beach erosion in the universal sense. Human activities are of great significance to the evolution of Shimei Bay Beach.
