| 摘 要： | 海洋在第四纪全球气候和环境的变化中起着至关重要的作用，一方面，海洋沉积记录了大量第四纪古全球变化的信息，特别是可提供古球变化中高分辨率的短期气候事件的记录，另一方面，无论是全球性大洋环流，生物和化学的变化，还是区域性西太平洋边缘海浅水陆架的出没，这些海洋事件都可能是许多第四纪古全球变化现象的原因之所在。因此，从海洋角度研究第四纪古全球变化，已成为当前古全球变化和国际古海洋学研究的重点。在这方面，深

| Abstract: | The sea which covers 71% of the Earth's surface plays a very important role in Quaternary changes of the Earth's climate and environment. Firstly,marine sediments contain a lot of information on Quaternary past global change,providing high-resolution records of short-term climatic events such as Younger Dryas event. Secondly, marine events, being changes in the circulation,biololgy and chemistry of the global ocean,or regional changes of the eustasy-induced emergence and submergence of shallow-water shelves in the western Pacific marginal seas, all can be causes of many phenomena of the Quaternary global changes. Therefore,Quaternry past global change studies from the marine aspect have become one of foci of the current international endeavor in global change science and paleoceanography. Great contribution to the field have been made by the Deep Sea Drilling (DSDP)/Ocean Drilling Program (ODP) and other related marine science programs. |
