A SUMMARY REVIEW OF RESEARCH PROGRESS ON GLOBAL CHANGE IN THE SOUTH CHINA SEA
-
摘要: 本文以文献资料和作者的工作成果,简略回顾了近年来南海海域全球变化研究的若干重要进展,其中包括:南海深海区已经初步建立了约33Ma以来的年代地层学框架,查明了一系列长时间尺度的环境变化阶段、轨道演化周期及其转型(如"中更新世革命")、突发环境事件(如大火、火山、玻璃陨石事件)和短时间尺度的非轨道事件(如"新仙女木事件"、H事件和D/O事件)以及高分辨率环境演化记录。文中还指出需要加大南海的研究力度,以利于查明全球变化中的海-陆-气相互作用及其动力学机制。Abstract: On the basis of data from the litertures and author's study some important progresses of the research into global change in the South China Sea have been reviewed in this paper. The chronostratigraphic sequence covered about 33 Ma has been established; Long-term sequence records and high-resolution records of paleo-environment have been investigated; A series of paroxysmal events(such as the Middle Pleistocene Evolution,the Heinrich event,the D-O events,the fire events,the Toba volcanic event and the tektite event,etc.) have been discovered in the cores from the South China Sea.The results indicate that it is necessary to deepen the research into the South China Sea for understanding the coupled system of atmosphere-marine-continent and the dynamics of global change.
