围绕IODP 683号建议书,介绍东亚东倾地形格局与季风系统演化历史的相关研究。新生代全球宏观环境格局发生了一系列重大变化,表现为岩石圈活动强烈,板块漂移导致海陆格局和地貌格局的变化,并引发洋流和大气环流的改组,最终导致全球气候的重大变化。新生代岩石圈运动和气候变化表现最为典型的地区是亚洲,其中最具标志性和全球意义的地质事件是喜马拉雅山和青藏高原的隆升及亚洲季风系统的形成与演化。青藏高原隆升最直接的结果是亚洲地区现代地貌格局的形成,大江大河的发育,并在很大程度上影响了亚洲季风系统的形成与演化。综合大洋钻探计划683号航次建议书,计划在长江中下游盆地和东海陆架盆地实施钻探,以获得长江历史演化和东亚季风演化的地质记录,并为研究青藏高原的演化提供新的证据。
Around IODP 683, a study on the correlation between East Asian topography and monsoon evolution is presented. A series of major changes took place in the global macroecono-environmental pattern of the Cenozoic, characterized by intense lithospheric activity, plate-shifting resulting in changes in the pattern of land, sea and geomorphology, and the reorganization of ocean currents and atmospheric circulation, leading to major changes in the global climate. The most typical area of Cenozoic lithospheric movement and climate change is Asia. Among the most significant and global geological events are the uplift of the Himalayas and the Tibetan Plateau and the formation and evolution of the Asian monsoon system. The most direct result of the uplift of the Qinghai-Tibet Plateau is the formation of the modern geomorphological pattern in Asia and the development of great rivers, which have largely affected the formation and evolution of the Asian monsoon system. Integrated Proposal No. 683 for Ocean Drilling Project, it is planned to conduct drilling in the middle and lower reaches of the Yangtze River and the East China Sea shelf basin to obtain geological records of the historical evolution of the Yangtze River and the evolution of the East Asian monsoon, and provide new evidence for studying the evolution of the Tibetan Plateau.
