摘　　要：中国东部陆架位于亚洲大陆与西太平洋的过渡区域,是连接全球最大的沉积源-汇系统的重要纽带,记录了东亚构造变形、亚洲季风系统形成与演化、海平面变化及东亚重大水系变迁等诸多重要信息。在总结前人研究的基础上,结合最近20年来中国海洋专项获得的数据资料和研究成果,综述了中国东部陆架区第四纪以海侵-海退变化为主要特征的沉积环境变化,探讨了陆架沉积环境变化与区域构造、海平面和东亚季风气候变化的联系;基于目前在长江、黄河流域及东部陆架区开展的沉积物源-汇研究,讨论了长江和黄河贯通入海的可能时代及控制因素;提出新生代以来陆架地质环境演变与东亚构造历史、季风系统演化、海平面变化、重大水系调整及陆架有机碳埋藏的耦合机制研究是未来在中国东部陆架实施科学钻探的重点科学目标。The eastern shelf of China is located in the transitional zone between the Asian continent and the western Pacific Ocean.It is an important link connecting the largest sedimentary source-sink system in the world,and bears many important information on tectonic deformation in East Asia,the formation and evolution of the Asian monsoon system,sea level changes and major water system changes in East Asia.Based on the review of previous studies and the new data obtained from marine projects in China during the last two decades,this paper reviews the Quaternary sedimentary environmental changes in the eastern shelf of China,mainly focusing on changes in marine transgression and regression cycles,and discusses the connection between the Quaternary sedimentary environment in eastern shelf of China and regional tectonic,sea level and East Asian monsoon climate changes.Based on the previous sedimentary source-sink studies in the Yangtze and Yellow River basins and the shelf area,we discuss the timing of penetrating into the sea of the Yangtze and Yellow rivers and controlling factors.We propose that the coupling mechanism of the geological environment evolution in the eastern shelf of China with Asian tectonic deformation,monsoon system evolution,sea-level change,major water system adjustment and carbon burial since the Cenozoic is a key scientific goal for future scientific drilling in the eastern shelf of China.
