| 摘 要： | 对华南弧形砂质海岸体系的沉积环境、动力及其泥沙供给等条件进行了分析．结果表明：控制华南弧形砂质海岸形成的主要因素包括地域背景、陆架物质供应量、水动力条件、海平面变化等．其中，陆架供沙是弧形砂质海岸形成的主导因子，海面上升致使大量泥沙存在向岸运动的趋势；波浪则是叠加在这种趋势上促使泥沙向岸运动的动力因子． |

| Abstract: | The deposition environment, dynamic action and sediment supply of the arc-shaped sandy coast system in South China were analyzed. The results show that the formation of the arc-shaped sandy coast in South China is mainly controlled by the factors including the region geology, material supply from continent shelf, hydrodynamic condition and sea-level changes, etc. Among them factors, the a key factor is the sediment supply from the continental shelf which controls the coastal formation. Meanwhile, the rising sea-level makes the large quantity of sediment appear a trend to move shorewards. Imposing on this kind of trend, the wave is the motive force to transport the sediment shore wards. |
