沉积物古 DNA 重构动植物群落变化及人地关系的研究进展

The sedimentary ancient DNA indicator, which has emerged in the past two decades, has a great bio-taxonomic breadth and has opened a new window for understanding the evolution of marine, lacustrine and terrestrial Quaternary biological environments and human-earth interaction on a global scale. However, the application of this new indicator in China is extremely limited and seriously lags behind the international research level. Based on the introduction of the identification experimental procedure of the sedimentary ancient DNA indicator and the results of the preliminary experiments in China, this paper reviews the applications of the sedimentary ancient DNA composition in reconstructing the response of flora and fauna community to climate change in the geological-historical period, the dispersal of flora and fauna due to human migration and its environmental effects, and the historical evolution of human agro-pastoral activities, etc. The future research directions and perspectives of sedimentary ancient DNA are prospected to promote the application and development of the sedimentary ancient DNA indicator in the field of Quaternary climate and environmental archaeology in China.
