摘要
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。
Using the survey data of shallow seabed in Chengbei since 1988, we studied the formation and evolution of unstable topography, and analyze the recent evolutional trend of unstable topography of the old Yellow River subaqueous delta. Then, we provided the main characteristic of micromophology evolutions and suggest that waves are the main outer dynamic factor controlling micromorphological changes.
