摘要: 本文根据青藏高原东部希门错短柱岩芯XM9201沉积物的物理、化学和生物指标的综合分析，讨论了该区2000多年来的气候变化过程。结果表明，2000多年来希门错地区总体表现出变暖的趋势，可以区分出4个阶段，即780～430B．C，480～1460A．D．的暖期和430B．C．～480A.D，1460～1900A．D．的冷期。另外，还对比我国东西部历史气候记载及冰芯研究，探讨了不同气候事件的特点。

Abstract: The climate in the last 2000 years has been highlighted in the field of global change' It is a very important time stream in PAGES to link the geological record with instrumental--gauge data' The past study in China for the climatic change of this time stream is concentrated in the historical record and ice core, because they all have very good resolution' The study on lake sediments is also a good tool for this purpose' With the support by lake drilling session of CCP project "Study on the Tibetan Plateau uplifting, environmental change and ecological system", the authors choose the Ximen Cuo, which is of little human impact, for the study of the palaeoclimate in the past 2 000 years.
