湄州湾强劲的潮流导致外海泥沙输入,但受一定程度的限制,海湾周围的陆源碎屑成为沉积物质的主要来源。水动力,特别是潮流作用控制现代沉积的格局,潮流冲刷槽为粗粒沉积属海底冲刷产物,两侧的斜坡及潮坪,从湾中央向岸,从粗细混合沉积物过渡为细粒沉积,属淤积产物。 The strong tide of the Meizhou Bay has led to the import of sediment from the outer ocean. However, due to some restrictions, terrigenous debris around the Gulf has become the major source of sediment. Hydrodynamics, especially the tidal current, controls the pattern of modern sedimentation. The tidal current scouring trough is coarse sediment belongs to the scouring products on the seafloor, both sides of the slope and tidal flat, from the central bay to the shore, from thick mixed sediment to fine sediment deposition, Is a siltation product.
