摘要
中国东部沉降海岸及近海钻孔研究表明，第四纪大部分时间里，福建—岭南隆起带基本阻挡了海水大规模进入东海—黄海盆地，约在１６０ｋａＢＰ已有低海相性的海侵出现，但是自末次间冰期以来才开始发生大规模海侵，而此时青藏高原正以空前的速率隆升。晚第四纪福建—岭南隆起带大部沉降入海底，维持了青藏高原与日本—琉球岛弧之间的地壳应力平衡；海水在晚更新世前后进入东海—黄海盆地，使中国大陆处于与海洋更密切联系的状态，其本质原因是陆架盆地沉降与青藏高原隆起对应的地壳变形。自此以后，长江、黄河及滦河与全球海洋水圈变化引起的海侵发生了复杂的陆海相互作用。
The study of boreholes in the subsided coastal plain and in offshoe area in China shows that at the most part of Quaternary sea water had been blocked from invading the Yellow Sea Basin and Eastern China Sea Basin as a result of the uplifting of Fujian Lingnan when the Qinghai Tibetan Plateau was rising at an unprecedented rate.The subsidence of most of Fujian Lingnan uplift to the sea floor since Late Quaternary had kept the isostatic balance between the Qinghai Tibetan Plateau and Japan Ryukyu Island Arc.As sea water entered into the East China Sea and Yellow Sea Basins since about Late Pleistocene,China continent became closely linked to the sea,due to the crustal deformation of the subsidence of continental basins and the corresponding uplifting of the Qinghai Tibetan Plateau.Since then there has occurred complex land sea interaction between the Yangtze River,Yellow River,Luanhe River and transgressions caused by the eustatic changes.
