根据青藏高原东部若尔盖盆地ＲＭ孔湖泊沉积物自生碳酸盐碳氧同位素，碳酸盐含量，木本花粉含量以及有机质含量分析，重建了１４万年以来的古气候与古环境过程，结果表明，１４万年来有５个气候环境显著变化时期，对应于深海氧同位素５个阶段５阶段对应于未次间期，又可分为５个次级阶段（５ａ－５ｅ），其中５ｅ又可进一步分为（５ｅ_１－５ｅ_５），４阶段以来记录了一系列冷事件，文章对ＲＭ孔记录与邻区及全球的相关记录进行了对比研究表明，３阶段同样是一个引人注目的时期，气候条件改善明显．
Based on the analysis of the carbon and oxygen isotopes, carbonate content, woody pollen content and organic matter content of the spontaneous carbonates in the sediments from the RM hole in the Zoigê Basin, east of the QinghaiTibet Plateau, the paleoclimate and paleoenvironmental processes of 140,000 years have been reconstructed. There are 5 climate change periods in 140,000 years. Corresponding to the 5 stages of deep-sea oxygen isotopes, 5 stages correspond to non-inter-stage and 5 sub-stages (5a-5e), of which 5e can be further divided (5e_1-5e_5), a series of cold events have been recorded since the 4th stage. A comparative study of records of RM pores with records of neighboring areas and the whole world shows that the 3 stages are also an attractive period with improved climatic conditions obvious.
