我国泥炭纤维素同位素记录的古气候变化研究进展

A REVIEW OF PALEOCLIMATIC CHANGES IN CHINA BASED ON PEAT CELLULOSE ISOTOPIC RECORDS

  • 摘要: 泥炭作为一类重要的地质载体,在开展古气候(尤其是全新世古气候)变化研究方面,具有一些其他地质载体所不具备的天然优势,特别适合开展有机地球化学和同位素地球化学方面的研究工作。概括了目前我国泥炭纤维素同位素研究的现状,对已经获得的数据进行了详细的总结和分析,结合与其他地质载体所获得的最新成果的对比,指明了目前我国泥炭纤维素同位素应用于古气候研究当中所存在的一些问题。产生这些问题的一个重要原因很可能是由于缺乏详细的现代过程研究,以至泥炭纤维素同位素代用指标的古气候指示意义因缺乏现代参照而不能加以明确。在此基础上,对我国泥炭纤维素同位素的进一步研究进行了展望,指出了在以后研究当中值得注意的几个方面。

     

    Abstract: Peat, as an important geological archive, has some internal advantages over other geological archives in researching paleoclimatic changes (especially the paleoclimatic changes during Holocene), and is particularly suitable for organic geochemistry and isotopic geochemistry studies. There are many peat bogs in China. Various researches have been conducted on these peat archives by both the domestic and international scientists,and important progresses have been reached. In this paper, we made a comprehensive review of the reported stable isotopic results for peat cellulose in China. The available data has been carefully collected and analyzed, upon the comparison with the latest results of paleoclimatic reconstruction obtained from other geological archives, then discussed are the critical problems about the application of peat cellulose isotopes in paleoclimatic research. We believe that these problems come from the insufficient study of modern-process. Therefore, the paleoclimatic significance of the stable isotopes of peat cellulose from a specific locality is not certain, due to lack of modern analogues. Finally, a discussion was devoted to the future development of stable isotopes of peat cellulose in China and some methodological problems.
