中文摘要:

      随着全球变化研究的不断深入，青藏高原湖泊沉积物的研究得到很大发展。作为高分辨率古环境变化的“记录仪”，湖泊沉积物在重建晚第四纪全球环境变化中具有特殊的地位和意义。湖泊沉积物中储存的各种信息反映了矿物学、同位素地球化学、生物学、沉积学等方面对气候环境变化的响应。在古环境变化研究中，湖泊沉积物已经从定性化研究逐渐过渡到定量化研究。

英文摘要:

      As high-resolution recorders of paleoenvironmental and paleoclimatic changes,lake sediments have great significance in climatic and environmental reconstruction of late Quaternary in Tibet.Much qualitative and quantitative progress has been made in minerals,isotopes,geochemistry,ostracoda,pollen,etc.The present paper gives a tentative review on such progress.
