末次盛冰期以来长江入海历史的回顾与展望

比较全面地回顾了末次盛冰期以来有关东海海平面变化、长江入海历史、长江河口海岸演变、陆架上的古河道等方面的研究进展 ;分析了关于末次盛冰期时长江入海状况现存两种截然不同的看法 ,指出了可能存在的问题。提出了今后的研究方向 ,即应加强对因气候、海平面变化引起的河道变形作用以及长江与古环境间的相互作用及相互影响的研究 ,特别是应加强对陆架泥质沉积物的研究 ,以期取得突破性进展

Entering sea histroy of the Yangtze River during the Last Pleniglacial stage

The development of the studies in the fields of the eustatic change of the sea level of the East China Sea, the history of the Yangtze River entering the sea, evolution of coast at entry of the Yangzi River and paleochannel in the shelf of the East China Sea since the Last pleniglacial was summarized. The two opposite existing opinions about the history of the Yangtze River entering the sea were analyzed. It is concluded that it is necessary to enhance the studies on the evolution of the Yangtze River, and the paleo-climate and the corresponding events as a whole from the view of regional and even global change. At present, the response of the Yangtze River to the changes of climate and sea-level is urgent to be considered, and the channel metamorphosis must be brought into the further work. The study of shelf mud sediment will be the key content in the future research.
