| 摘 要： | 对长江三峡巫山下沱遗址考古进行了研究,揭示了本区古沉积环境变化以及古洪水情况。根据考古器物排比法研究,遗址剖面为商周以来的沉积地层。磁化率和孢粉综合分析结果表明商周、汉代末期、唐宋文化层磁化率值较高,孢粉组合以木本和草本植物为主,有少量的蕨类植物,并有淡水藻类出现,木本主要为青冈属、芸香科、忍冬属、桃金娘科和朴属等,反映气候温暖湿润,有助于古文化的发展和兴盛。 |

| Abstract: | From archaeology stratigraphy of the Xiatuo site at three Gorge of Yangtze River,sedimentary changes and paleo-flood in this area are made clear.The method of cultural relic comparison is used o estimate the sediment time of the site to be Shangzhou Dynasty.Susceptibility values of cultural layers during Shangzhou Dynasties,the late Han Dynasty,Tang and Song Dynasties are higher than those of other layers.Pollen assemblages are dominated by arboreal and herb pollen with some freshwater algae.Arboreal pollens are mainly composed of Cyclobalanopsis,Rutaceae,Lonicera,Myrtaceae and Celtis.It revealed that the climate was warm and humid which was in favor of the development of human civilization.Sedimentary and pollen research showed that there were at least three super floods since the Neolithic. |
