中文摘要:
      本文通过漳卫河流域ZKD-3 钻孔前78.6m沉积物的光释光测年结果和粒度、磁化率测试结果进行分析,还原了漳卫河流域220kaB.P.以来的古环境的演化历史。根据测试结果,可将漳卫河流域220ka BP以来古环境分为5个变化阶段:223.4~196.5ka B.P气候温暖湿润;196.3~187.3ka B.P.气候开始转向寒冷干燥;185.6~87.4ka B.P. 气候为寒冷干燥,并逐渐转向温暖湿润;84.5~12.6ka B.P.气候整体为寒冷干燥,;9.87~0.68 ka B.P.经历了温凉略干→温暖湿润→温凉偏干。漳卫河流域的气候演化即具有全球气候变化一致性特征,同时也受区域特征的影响。
英文摘要:
      Sediments were sampled from the depth 78.6m in the Zhangwei River Basin. Based on the analysis of OSL dating, grain size, mineral-magnetism measurement, to resore the change of palaeoenvironment Since 220ka.B.P, in this area. The evolution processes can be divided into 5 periods: 223.4~196.5ka B.P , the climate was warm and humid in this period;194.62~187.33ka B.P. , the climate begun turning into cold and dry In the period of 185.6~87.4ka B.P. , the climate was cold and dry, then gradually getting warm and humid; In the period of 84.5~12.6ka B.P. , the climate was cold and dry generally; 9.87~0.68 ka B.P., the climate got warm and wet in this period the climatic changes were from slightly cold and moderately dry→ warm and humid →warm and humid→slightly worm and moderately dry process. The results show that climate evolution has the characteristics of the global synchronization,but also affected by the characteristics of the region.
