| 摘 要： | 渤海西岸、南岸从全新世海侵边界至现在海岸线之间的海岸低地是7 000 a B.P.以来多个三角洲进积的结果.由于黄河人海泥沙数量巨大,导致下游河道频繁摆动,活动三角洲(超级叶瓣)位置多次变迁.滦河三角洲活动叶瓣位置也多次变迁.海岸线变迁受三角洲演化控制:活动期推进、废弃初期后退和之后的长期稳定,表现分片突进模式.整体来说研究区各时期海岸线表现出局部突出、局部内凹特点.在这样的三角洲群地区不可能出现近乎匀速的平推式海岸变迁.

| Abstract: | The coastal lowland between the Holocene transgression extreme and present coastline is prograded by several river deltas: the Luanhe River Delta,old Yongding River-old Chaobai River Delta,old Ziya River-old Daqing River Delta,Haihe River Delta,Huanghe(Yellow) River Delta and Weihe River-Mihe River Delta.The change of the coastline is controlled by evolution of these deltas: progradation in the active stage of the delta lobe or delta superlobe,retreat in the early time of the abandoned stage and then stabil... |
