The study of Quaternary sedimentary environment of different tectonic units in Hebei Plain is helpful to understand the change of sedimentary paleoenvironment. Dachang depression is located in the north of Hebei Plain, and the work on its sedimentary environment are few. We study the change of sedimentary environment since late Pleistocene in the Touying section in the northern Dachang depression, and to provide some references for understanding the evolution of sedimentary environment of Hebei Plain.Methods:The grain- size characteristics of the Touying section has been studied by grain size samples. The formation age of the profile was analyzed by 14C and OSL dating. Samples were taken from the profile for sporopollen research.Results: The Touying section can be divided into 18 layers and the sediments are dominated by clayey silt, silty clay and clay. The probability accumulation curve is dominated by fine type, and the sample is mainly composed of saltation population and suspension population. 14C and OSL dating results show that the measured stratigraphic section be accumulated at the end of late Pleistocene. According to the characteristics of palynology assemblage, the profile can be divided into three palynology belts. Along sporopolen zone I, the climate was warm and moist. Along sporopolen zone Ⅱ, the climate was cold and dry, Along sporopolen zone Ⅲ, the climate was warm and moist. Conclusions: The comparison between the measured section dating results and the oxygen isotope curve of the Guliya ice core showed that the Touying section experienced a warm—cold—warm climate change, which was consistent with the climate characteristics reflected by the palynology assemblage. The age of the section corresponds to MIS3—MIS1 stage. The sediments of Touying section should belong to floodplain or depression facies since late Pleistocene. The Touying section was formed on relatively stable low- flow conditions and the sedimentary environment was stable.
