摘要
类脂化合物极大地扩展了全球变化研究的深度,尤其是单体碳稳定同位素技术在古气候、古环境重建上有着重要作用。基于近些年来国内外的最新研究成果,就类脂化合物单体碳同位素在古气候环境方面的应用研究进行了较为全面的评述。已有研究表明利用类脂化合物单体碳同位素组成可以追溯到海洋和湖泊环境中陆源有机质的物源,其母源区历史时期C3、C4植被的变迁以及区域性的古气候、古环境重建。
It is indicated that lipid biomarkers deeply widen the aspects of the past global change. Especially, the compound-specific carbon stable isotope technique has become a powerful tool for the reconstruction of the paleo-climate and paleo-environment during recent years. The recent progresses on the understanding of paleo-climate and paleo-environment using compound-specific carbon stable isotope as a proxy are reviewed in his paper. It is supported that the compositions of compound-specific carbon stable isotope of lipid can effectively track the sources of terrigenious organic debris in the marine and lake environment, understand the variation of C3 and C4 plants in the historical period, and reconstruct the regional paleo-climate and paleo-environment.
