末次冰消期以来古气候演化研究进展及展望

 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。

Paleoclimatic Evolution Since the Last Deglaciation: A Review and Prospect View

During the last deglaciation, enormous changes occurred on the global surface. A series of abrupt climate changes occurred during this period in different ways and different parts of the world. The warming process and mechanism has been the focus of studies of paleoclimate changes, however, controversy still exists. This paper briefly reviews the development of paleoclimate and monsoon evolution since the last deglaciation, and it is pointed out that the continental shelf area is very sensitive to the global environmental changes. The shelf sediment also contains a wealth of climate/monsoon evolution information. Extraction and study of the proxies derived from the shelf sediments should be valuable. East Asian monsoon evolution history and its driving mechanism, the monsoon differences and interaction, monsoon-driven mechanism analysis in various time scales revealed by the sediments on the continental shelf are of great significance for regional and global change studies. It is suggested that the future work is to study the paleoclimate and the corresponding events in view of regional and even global changes, and more attention should be paid to the study of the continental shelf sediments.
