作为重要地质档案的泥炭已经成为全新世气候变化研究最有价值的陆地载体之一,尤其是在同位素地球化学方面最有潜力。有综述指出,中国泥炭碳、氧同位素古气候研究缺乏现代过程的验证。通过总结国内外泥炭植物纤维素碳、氧同位素现代过程及其在古气候研究中的应用现状,其中包括泥炭植物应用于古气候重建的材料选择、维管束和非维管束植物纤维素碳、氧同位素的指示意义研究进展。进一步分析已有研究中泥炭碳、氧同位素存在的问题,结合中国泥炭植物碳、氧同位素古气候研究现状,为中国后续开展泥炭相关工作提供思路指引。
Peat as an important geological archive has become one of the most valuable terrestrial carriers for climate change research in the Holocene, especially in isotope geochemistry. It has been pointed out that the studies on paleoclimate of peat carbon and oxygen isotopes in China lacks the verification of modern processes. By summarizing the modern processes of the carbon and oxygen isotopes of cellulose in the peat plants both at home and abroad, and their application status in paleoclimate research, including the selection of materials for peat plants in paleoclimate reconstruction, vascular bundles and non-vascular plant cellulose carbon and oxygen Research Progress of Indicative Meaning of Isotopes. Further analysis of the existing problems of peat carbon and oxygen isotopes in existing research, combined with the current research on the paleoclimate of carbon and oxygen isotopes in peat plants in China provides guidance for the follow-up of peat-related work in China.
