摘要:

木质素与其他生物标志物相比较,具有稳定、专一、多样、广泛等优点,在古植被变迁的研究中发挥着重要作用,并显示出一定的发展潜力和应用前景。综述木质素在古植被演化方面研究进展的同时,着重叙述了木质素的化学结构及其衍生物、分析方法,阐述了木质素组份参数和单体稳定碳同位素组成在古植被应用中的研究现状和发展趋势,分析和讨论木质素在古植被重建中的优势和局限性;并针对目前存在的问题,提出了相应的研究思路。

关键词: 木质素, 生物标志物, 古植被, 古气候, 重建

Abstract:

In comparison to other biomarkers, lignin has more advantages such as stableness, specification, diversity and ubiquity, and so on.Lignin plays an important role in reconstructing the history of paleo-vegetation, and is widely applied to many disciplinarities in recent years and shows great potential and application prospect.Based on recent progresses, the chemical structures of lignin and its derivatives are reviewed.Focused on current situations and developing trends of the application of lignin parameters and stable carbon isotope of individual compounds, the analysis methods and the advantages of the application are discussed.Furthermore,a new study method for lignin research is suggested to solve the problems in reconstruction of the history of paleo-vegetation.

Key words: lignin, biomarker, paleo-vegetation, paleo-climate, reconstruction
