Plant sedimentary ancient DNA is an advanced method to analyze the information on paleovegetation, which can provide a broader perspective and additional details regarding paleovegetation and paleoenvironment from the perspective of molecular biology. We analyzed the main factors influencing the preservation of ancient plant sedimentary DNA. In addition, we outline the process of plant sedimentary ancient DNA analysis. We synthesized the progress of research on plant sedimentary ancient DNA in the dynamic evolutionary processes of plant communities, the reconstruction of climate and environmental changes, and the reconstruction of ecological evolutionary responses to human activities. By providing rapid, high-resolution information on ancient plant species, the ancient DNA analysis of plant sediments can be used to reconstruct the evolution of plant communities, quantitatively and semi-quantitatively reconstruct paleoclimates, and explore the impacts of human agricultural and pastoral activities on ecosystems. In the future, we should construct more perfect reference data for the DNA classification of plant species, strengthen the burial study of plant sedimentary ancient DNA molecules, promote the application of plant sedimentary ancient DNA in Quaternary paleoenvironmental research, and combine it with multiple indices to obtain more detailed paleoecological information. Therefore, plant sedimentary ancient DNA plays an important role in understanding the relationships between ancient vegetation, climate change, and human activity.
