摘要：
通过对北京平原区3个孔（顺义高丽营GZK1孔、昌平马池口CHZK1孔及大兴DZK1孔）的孢粉资料进行研究和对比，分析了北京平原区中更新世以来的气候变化，并将其划分为8个阶段：第1阶段气候较寒冷干旱，第2阶段气候温暖湿润，第3阶段气候温凉较湿，第4阶段气候温暖较干旱，第5阶段气候较寒冷干旱，第6阶段气候特征为早期暖湿，晚期温凉干旱，第7阶段气候较寒冷干旱，第8阶段气候温和湿润。
Abstract:
Through studies and correlation of the 3 boreholes(Shunyi Gaoliying GZK1 borehole， Changping Machikou CHZK1 borehole and Daxing DZK1 borehole)in Beijing plain area， this paper analyzed the climate and vegetation change of this area since the Middle Pleistocene and the process was divided into 8 stages. During the first stage， the climate was cold and dry; during the second stage， the climate was warm and moist; during the third stage， the climate was cool and wet; during the forth stage， the climate was warm and dry; during the fifth stage， the climate was cold and dry; during the sixth stage， the climate was warm and damp in early time and cool and dry in late time; during the seventh stage， the climate was cold and dry; during the eighth stage， the climate was warm and wet.
