Based on the landforms, sedimentary sequence, fossil fauna and flora, and paleoclimatereflected by them as well as 14~C datings, the Late Quaternary strata in Beijing Plain canbe divided into six members. In this paper, the history of paleogeographic evolution and theinteraction between geographic elements of this area during the past 30,000 years are de-scribed in detail.
