【摘要】：随着全球变化研究的不断深入,人类文明发展阶段的考古聚落遗址地层记录和全新世以来连续沉积的自然地层记录已得到国际学术界和各国科学家越来越多的关注。长江三峡地区有着丰富的全新世考古遗址资源,为新石器时代以来人类活动和环境变化的环境考古研究提供了良好基础和条件。其中的中坝遗址具有厚度大、地层时代齐全完整、出土器物量多、并有大量种类繁多的脊椎动物骨骼(包括哺乳类、鸟类、鱼类、两栖类、爬行类)、测年材料和古洪水沉积地层现象丰富的特点;该区同时又有全新世以来自然连续沉积厚度达3m以上的大九湖泥炭沉积地层。对该区典型遗址和连续沉积的自然地层作比较研究,通过人类活动和环境演变的指标信息提取和时间序列的建立,可恢复该区全新世以来人类活动史、古洪水史,弄清人类活动和自然环境的关系及其对全球变化的响应,并建立三峡地区全新世以来标志性考古遗址地层剖面。
[Abstract]:With the deepening of the study of global change, the stratigraphic records of archaeological settlement sites in the development stage of human civilization and the continuous deposition of natural stratigraphy since Holocene have received more and more attention from the international academic community and scientists from all over the world. The three Gorges area of the Yangtze River is rich in Holocene archaeological site resources, which provides a good basis and conditions for the study of environmental archaeology of human activities and environmental changes since the Neolithic Age. The Zhongba site has a large thickness, complete and complete strata age, a large number of unearthed utensils, and a large number of vertebrate bones (including mammals, birds, fish, amphibians, reptiles). The rich characteristics of dating materials and paleo-flood sedimentary strata; At the same time, there are peat sedimentary strata in Dajiu Lake with a natural continuous sedimentary thickness of more than 3m since Holocene. A comparative study on typical sites and continuous sedimentary natural strata in this area is carried out. through the extraction of index information and the establishment of time series of human activities and environmental evolution, the history of human activities and ancient floods in this area can be restored since Holocene. To clarify the relationship between human activities and natural environment and its response to global change, and to establish the stratigraphic profile of iconic archaeological sites in the three Gorges area since Holocene.
