晚更新世以来古气候与海平面变化在东海地区的响应

第四纪特别是晚更新世以来气温的大幅度冷暖变化,导致全球海平面的变化,引起陆架海侵和海退。东海陆架的气候和海平面变化与全球变化基本同步。晚更新世以来,东海陆架随全球气候变化发育多次海进海退旋回。东海陆架上的古河道、古三角洲和潮流沙脊等沉积体系的形成和演化与海平面升降变化存在耦合关系。

THE RESPONSE TO THE VARIETY OF PALEOCLIMATE AND SEA LEVEL IN THE EAST CHINA SEA AFTER THE LATE PLEISTOCENCE

Large amplitude changes of the atmospheric temperature in Quaternary especially after the late Pleistocene induced the global sea level changes and continental shelf transgres- sions and regressions.The climate and sea level changes in the continental shelf were the same as the global changes.After the late Pleistocene,with the global climate changes. there were several transgressions and regressions on the continental shelf.The paleoriver- way,paleodelta and tidal sand ridge in the continental shelf of the East China Sea,coupling to the sea level change,have had new evolutions and changes.
