摘要: 通过对苏北盆地YZ浅钻沉积物磁化率和粒度指标的分析，揭示了区域气候环境的变化过程和特征。研究结果表明，16.7～13.5 cal kaBP气候相对温暖湿润；13.5～11.2 cal kaBP为一个较为显著的冷干期；11.2~1.1 cal kaBP为一整体气候相对稳定期，以温暖湿润为特征；另外，还记录到了多次的气候波动事件，其中较为显著的为YD事件和发生于3.0 cal kaBP的气候事件。研究结果与中国西南贵州董歌洞石笋和格陵兰GRIP冰芯等记录有着较好的对比，但在细节上存在着一定的差异，这反映了研究区的气候环境变化具有自身的区域性特征，同时也反应了与全球气候变化的一致性。

Abstract: Based on the synthetic analysis of the mass susceptibility and grain size from the YZ core obtained from Subei basin, the process and characters of palaeoclimate evolution during the past
16.7 ka were revealed. The results show that during the past 16.7 cal kaBP, the palaeoclimate of Subei basin has experienced several phases: 16.7~13.5 cal kaBP, relatively humid period; 13.5~11.2 cal kaBP, extremely arid period; 11.2~1.1 cal kaBP, relatively steady humidity period. In addition, the indexes also recorded several climate events. YD event and 3.0cal kaBP events are obviously. The aridhumid fluctuations since around 16.7 ka disclosed by YZ core reveals a strong correlation with the GRIP oxygen isotope record and Donggedong’s stalagmite oxygen isotope record. This indicates that the climate changes in the study area not only has great regional character, but also has great correlation with the global climate changes.
