摘要
根据2005年开展的海底地形调查资料并结合前人资料，对废弃的黄河口三角洲海区的海底地形特征及演化进行了分析。通过分析表明，近20a来，本区海岸处于侵蚀状态，蚀退速率约在50～80m／a之间，海底地形处于冲刷状态，5m和10m等深线向岸方向移动600～900m。
Based on data of investigation and study on the bottom features and evolution launched in 2005 in the north part of the modern Huanghe River Delta coast and combining the historical information, the discussion of the features of terrain in the sea floor and evolving of the abandoned Yellow River delta was done. It showed that in the last 20 years, this coast was eroded, and its rate is among 50-80 m/a, and the topography is in the state of washing away in the sea floor, 5 m and 10 m isobaths move about 600-900 m to-ward coast.
