根据1988～1996年埕北浅海区的海底调查资料,深入探讨了海底不稳定现象的形成及发育机制,分析了老黄河口水下三角洲不稳定地形的近期演变动态,提出海底地形及地貌演变的主要特征。并指出波浪是控制海底地形及微地貌变化的主要外动力因素。
According to the seabed survey data in Chengbei shallow sea area from 1988 to 1996, the formation and development mechanism of unstable seabed phenomenon are discussed in depth. The recent evolution of submarine delta unstable terrain in the Yellow River Estuary is analyzed. The main features of submarine topography and topographic evolution feature. And pointed out that wave is the main external dynamic factor that controls submarine topography and micro-topography.
