1996～2014年黄河三角洲海岸线遥感动态监测

Dynamic Monitoring of Coastline in the Yellow River Delta by Remote Sensing Since 1996

黄河三角洲是世界各大河三角洲最为活跃的地区之一,淤进和蚀退的交替演变造就了黄河口地区的造陆之快和尾闾迁徙之频繁.该研究以1996～ 2014年17景遥感影像为主要数据源,利用遥感与GIS技术相结合,对影像进行处理与转换,实现海岸线的动态监测,分析了刁口段研究区与河口段研究区的海岸线演变过程.结果表明,刁口段研究区总体处于蚀退状态,河口段研究区淤进和蚀退交替演变.

The Yellow River Delta is one of the most active delta regions in the world. The rapid epeirogenesis and the migration in the down- stream of Yellow River Estuary could be formed by alternating evolution of erosion and siltation. Based on the 17 scenes remote pictures since 1996 to 2014, the image of these pictures were processed and conversed by using GIS and RS technology. Besides, the evolution processes of the diaokou district and the Hekou district in recent years were analyzed by dynamic monitoring of the coastline. The result shows that Diaokou dis- trict in a state of erosion and the Hekou district in a state of alternating evolution of erosion and siltation.
