摘　　要：本文较为系统地分析了西南地区石笋、泥炭和湖泊沉积物等自然记录恢复古气候的其本原理,概述了西南地区全新世(近万年来)气候变化研究的主要进展。鉴于西南地区古气候研究的现状,未来应着重加强三个方面的研究:1)加强石笋、泥炭和湖泊沉积物等代用指标记录气候变化的机理研究,建立更为有效的古气候定量/半定量重建方法;2)加强高分辨率、多指标的综合对比研究,揭示重大气候变化事件(如8.2 ka事件4、.2 ka事件和小冰期等)的性质及其对西南地区生态环境的影响;3)加强不同区域气候变化的对比研究,为揭示气候变化驱动力和合理预测西南未来可能出现的气候变化提供科学基础。This paper analyzes in detail the basic principles of paleoclimate reconstruction and advances in research on climate changes recorded by multiple natural records which include stalagmite, peat and lake sediments in Southwest China during the Holocene. Future research should be focused on the following aspects： 1） to reinforce research on the mechanism of proxies to deduce climate changes and thus to establish quantitative/semi-quantitative reconstruction methods for paleoelimate; 2） to reinforce high-resolution research on multiple climate proxies on different time scales, revealing the nature of extreme climate change events such as 8.2ka cold-dry events, 4.2ka cold-dry events and Little Ice Age, and their possible effects on regional environments; 3） to reinforce comparison research among different regions, revealing the driving factors affecting climate changes and their influence on different regions. This study is helpful to understand the characteristics of climate changes in southwestern China and provide the basic information for predicting future climate changes.
