末次冰消期是全球气候与环境出现较大变化的时段,其间发生了一系列气候突变事件,在全球不同地区以不同方式回应着这些事件的变化过程。综述了末次冰消期以来青藏高原高寒干旱区、西北干旱区、云贵高原湿润区以及东部平原地区的湖泊沉积记录的古气候演化特征,探讨了气候变化的驱动机制,并提出未来该研究领域亟待深入开展的工作,包括拓展高分辨率湖泊沉积记录的气候演化时间序列研究,提升学科交叉和与其他地质记录的对比研究,加强中国第四纪湖泊数据库和全球气候变化研究,以及加强水汽来源示踪研究。
The last phase of ice-cooling is a period of major changes in the global climate and environment. During this period, a series of climate abrupt events have taken place and different processes in different regions of the world respond to the changes in these events. The paleoclimate evolution of lacustrine deposits in the arid region of the Qinghai-Tibet Plateau, the arid region of Northwest China, the humid region of the Yunnan-Guizhou Plateau and the eastern plains is reviewed. The driving mechanism of climate change is discussed and the future is urgently needed In-depth work includes expanding the time series of climate evolution records for high-resolution lake sedimentary records, enhancing interdisciplinary studies and comparative studies with other geological records, strengthening the research on China’s Quaternary lakes databases and global climate change, and strengthening the sources of water vapor Tracing research.
