摘要
根据历史图件与卫片对比,提出黄河三角洲刁口岸段近期岸线演化过程:填湾取直——快速淤进——逐步稳定——快速蚀退——缓慢蚀退——逐步稳定,还指出黄河泥沙的来源与分布,指出河口区动力环境的变化直接影响着岸线的进退速率和范围。
The coastline of the Diaokou section advanced rapidly as the Huanghe river flowed through the Diaokou channel from 1964 to 1976. But it has retrogressed since the Huanghe river changed its esturine location to the Qingshuigou channel in 1976. Comparison between the remote sensing images and the historical maps shows the recent evolutionary process of the Diaokou section coastline. Both the transportation and the distribution of the Huanghe river sediment and the complex dynamic environment in the esturine region are the main mechanisms affecting the coastline evolution.
