中文摘要基于RS和GIS,通过分区分析了1979—2013年黄河三角洲不同流路岸线变迁及冲淤变化的时空异质性及其驱动因素。发现1979—1986年间,由于黄河入海泥沙量高且处于改道清水沟初期,清水沟(Ⅵ区)和清8汊流路(Ⅴ区)向海延伸显著,此后入海泥沙量减少其变化明显减缓;1995年以后,黄河改道清8汊且2002年以来调水调沙增加了黄河的输沙能力,三角洲岸线变迁的幅度较2000年前增强;刁口河附近区域(Ⅰ、Ⅱ区),因黄河改道清水沟和清8汊流路,入海水沙补给显著减少,总体上处于蚀退状态;神仙沟流路区域(Ⅲ区),1986年以后除入海口处有变化外,其它区域因修建堤坝成为人工岸线而少有变化;莱州湾西侧区域(Ⅵ...
英文摘要Based on the RS and GIS,the paper analyzes the spatial and temporal heterogeneity and the corresponding forcing factors in the coastline changes in different branch areas of the Yellow River delta from 1979 to 2013.The Qingshuigou and Qingbacha branch areas extended significantly into the sea from 1979 to 1986with high water and sediment.The sediments decreased and the extension slowed down obviously then.After 1995,affected by the river’s migrating to Qingbacha and by the water-sediment adjustment since 2002,the capacity of the sediment transport from the Yellow River into the sea was enhanced,and the amplitude of the coastline change was increased compared with the situations before 2000.Because of the river’s migrating to Qingshuigou and Qingbacha branch areas,the transportation of the sediment into the sea was significantly reduced near Diaokouhe branch,and the nearby coastline was in a state of erosion.In Shenxiangou branch area,small changes in the coastline was resulted from the construction of dikes since 1986.The coastline around the Laizhou Bay reached into the sea overall due to the siltation and erosion.Thus,the spatial heterogeneity of the Yellow River delta coastline changes in different periods are mainly affected by the amount of the water and sediment transporting into the sea and the migration of the river.
