摘　　要：随着对全球气候变化的更多关注,对近千年来气候环境的影响机制及对其气候的重建已成为研究的热点.对于古气候古环境的重建,洞穴沉积物特有的微层结构及其稳定同位素和微量元素等指标的记录,已成为很好的陆地自然环境的历史档案.本文探讨了近千年来温度和降水重建研究的进展,并对洞穴沉积物的主要气候代用指标的研究状况进行了阐述,同时,分析了一些存在的问题及可能发展的趋势.With more attention to global climate change,the influencing mechanism and reconstruction of the climate and environment in the past 1000 years become a research hotspot. For the reconstruction of the paleoclimate and paleoenvironment,the lamina structure,the stable isotopes and the trace element of the cave sediment has become historical archives of the natural environment. In this research,the research progress of the temperature,precipitation and the main climatic proxies of the cave sediments in recent 1000 years are discussed,at the same time,some existing problems and the possible development trend are analyzed.
