The sedimentary characteristics and facies of the cultural layers in the late Paleolithic period of the late Late-Pleistocene in the Wangfujing Oriental Plaza site were studied based on the comparison and analysis of the typical sedimentation profile of the site and more than 150 stratigraphic data. The paleo-geomorphic surfaces during the periods of 2.2×104 a B.P. were rediscovered. The study suggests that the ancients must have acted in the sandy islands of alluvial fans, which were evolved in relatively steady water flows during the interglacial stage with slightly warming in the last glacial epoch. The cause of the absent of human activities between the upper and lower cultural layers in an interval of about 3.14×103 a has also been discussed in detail. It is concluded that this was resulted from the strengthening and unstable water flow. The potential former settlements or camping sites of the ancients prior to moving to this area are also discussed. It is suggested that they might came from other higher dissected old alluvial fan platforms evolved at the same period or earlier in the western part of the plain. These results provide evidences for the reconstruction of the geomorphic environment of Beijing plain during the Late Pleistocene and the study of prehistoric human history.
