孢粉稳定同位素研究进展初探

孢粉作为环境演变的指示剂,在开展古气候、古环境变化研究方面具有重要的研究意义和研究价值,但在孢粉研究过程中受到孢粉鉴定分类水平及鉴定者的鉴定水平等方面的影响,对古环境、古气候的研究就很难达到准确的定量研究的标准,对孢粉稳定同位素进行研究反而很好的解决孢粉研究过程中出现的不足。概括了目前国内外对孢粉稳定同位素的研究现状,对现在应用于孢粉同位素中的方法进行分析归纳,结合其它应用同位素的所获得的最新成果进行对比,从而指出现在孢粉稳定同位素研究过程中存在的问题和不足,提出未来孢粉稳定同位素发展的新趋势。

Preliminary study on the research progress of stable isotope of pollen

Pollen as an indicator of environmental evolution, it is of great significance and value in the study of paleoclimate and paleoenvironment change.However, in the process of pollen research, it is difficult to reach the standard of accurate quantitative research for the study of paleoenvironment and paleoclimate due to the influence of the identification and classification level of pollen and the identification level of appraisers. On the contrary, the study of stable isotope of pollen can well solve the problem in the process of pollen research. In this paper, the research status of stable isotope of pollen at home and abroad is summarized, the methods applied in pollen isotope are analyzed and summarized, and compares the latest results obtained by other applied isotopes, thus pointing out the current stable isotope study of pollen problems and shortcomings in the process, and propose a new trend of future stable development of pollen.
