摘要
在对安徽蒙城尉迟寺古文化遗址进行野外考察的基础上,分析了古文化沉积层剖面中的17种元素、pH值、TOC等数据,结果表明：①主因子分析得到的fact1可以反演距今5 050～4 000年间尉迟寺遗址地区古代人口数量的变化,变化曲线和传统器物考古方法得出的古文化层演变关系有很好的相关性;②在处于原始农耕文明的古代人类社会,人口数量的变化以及社会的兴衰与气候是息息相关的：夏季风越强,人口数量就越多,社会就越繁荣.孢粉分析结果表明4 400年左右的气候事件,导致尉迟寺遗址地区的大汶口文化与龙山文化的更替;③探索性的研究表明,地质地球化学方法可以应用在考古学研究中,并提供文明与气候的新信息.
A sediment profile from the Yuchisi Site, Mengcheng county of Anhui province, China, was collected, and the elemental concentrations, pH and TOC of the sediments were analyzed. The results show： （1）the first factor of factor analysis represents the human population changes at the Yuchisi Site between 5 050 a BP and 4 000 a BP, and the change pattern is consistent with one from previous archaeological studies; （2）the population and prosperity of ancient agriculture at the Yuchisi Site strongly depends upon climates： the stronger the East Asian Summer Monsoon, the bigger the population and the more prosperous the society. The result of pollen analysis indicates that the climate event occurring around 4 400 a BP very likely caused the transition of Dawenkou Culture to Longshan Culture of Yuchisi Site;（3）these ecogeological methods provide novel and powerful tools for archaeological research and new information about ancient civilizations and paleoclimate.
