The pollen dataset is an important basic data for the study of the history of paleoenvironmental evolution and the pattern of paleoclimate change at the regional scale.In this study,71 pollen sequences from the Last Glacial Maximum in Northeast China were processed.Firstly,the percentages of each pollen taxa were recalculated;Secondly,revised the chronology,and the age models were regenerated;Finally,the pollen sequences were interpolated with a 1000-year resolution.Therefore,a standardized and harmonized fossil pollen database has been established,and the database information was displayed in combination with GIS technology,and the characteristics of paleovegetation evolution in Northeast China were reconstructed.The dataset can be effectively applied to the study of paleoenvironmental evolution in Northeast China.
