| 摘 要： | 通过10帧黄河三角洲地区不同时相卫星遥感影像对比和利用实测水深资料,对1976年以来黄河三角洲海岸线的冲淤变化规律及过程进行分析研究。利用遥感监测数据构建海岸线演变回归模型,对海岸线的未来形态变化进行预测。研究结果表明,三角洲总岸线长度自1992年来逐年减小;刁口岸段自1976年来由持续侵蚀向冲淤平衡过渡;新河口岸段自1976年来不断淤积扩张,但近年来陆域面积开始出现缩小趋势。

| Abstract: | In this paper,the analysis and study of regularities and processes of scour and silting variations in the Yellow River delta coastline since 1976 were made by comparing 10 satellite remote sensing images of the Yellow River delta area in different times and using the observed water depth data.The remote sensing monitoring data are used to formulate the regression model of coastline evolution to predict the variations in coastline morphology in the future. It is shown from the study results that the total delta coastline length was gradually decreasing since 1992;the Diaokou coast section changed from continued erosion to scour sedimentation equilibrium since 1976;the new river mouth coast section was in a continuous siltation and expansion process since 1976,but the land area in the section began to show a reduction trend in recent years. |
