从盛冰期到全新世之间的末次冰消期经历了地球表层系统的一次巨变,期间发生了一系列气候突变事件,在全球不同地区以不同的方式回应着这些事件的变化过程。末次冰消期转暖的过程和机制一直是古气候研究的热点。本文综述了末次冰消期以来的古气候/季风演化研究成果,指出海陆交界敏感地带的陆架区对全球环境变化十分敏感,陆架区沉积物蕴含了丰富的气候/季风演化信息,对陆架区沉积物中古气候代用指标的提取,东亚季风演化历史及其驱动机制、季风的差异和交互作用、季风在各个时间尺度上的驱动机制等问题的分析均具有重要意义,可以为地区及全球环境变化提供科学依据。
The last phase of ice removal from the Ice Age to the Holocene experienced a drastic change in the Earth’s surface system during which a series of climate abrupt events took place that responded differently to these events in different parts of the world. The process and mechanism of warming up in the last ice age has been a hot research topic in paleoclimate. This paper summarizes the paleoclimate / monsoon evolution studies since the last deglaciation, and points out that the continental shelf is sensitive to global environmental changes. The sediments in the continental shelf contain abundant information on the evolution of climate and monsoon, The extraction of paleoclimate proxy indicators, the evolution history and driving mechanism of the East Asian monsoon, the differences and interactions of the monsoon, the driving mechanism of the monsoon on various time scales and other issues are of great significance and can provide regional and global environmental changes Scientific basis.
