Abstract: 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.

摘要: 通过对遗址地层典型沉积剖面和遗址地区150余个地层资料的对比分析,揭示了北京王府井东方广场晚更新世晚期旧石器人类遗址地层的沉积特征与沉积相类型,从而恢复了距今2.2万年前人类在此生存活动的古地貌面。研究表明,古人类曾活动于古冲积扇面的砂岛上,这是末次冰期间较温暖的间冰阶时期,是一个水流相对稳定的时期。还讨论了由于受较强的不稳定水流影响,使该文化层内有3140年没有人类的活动,认为该遗址是一个人类活动的临时营地。并且,在同一时期,人类可能来自周围的古冲积扇高地,或来自平原西部较早形成的高地貌面。以上的研究为北京平原晚更新世晚期人-地环境的重建和进行史前人类历史的研究提供依据。
