摘要
通过对浙江田螺山遗址剖面进行野外采样,实验室测定粘土矿物的种类、含量,以及地球化学元素硼、锶、钡的含量,恢复沉积物的古盐度,探讨田螺山遗址的相对海面变化,认为河姆渡文化层之前、之中、之后都存在相对海面较高的时期。综合多种环境要素并结合前人的相关研究成果,对田螺山地区的环境背景特点及其同古代人类活动、河姆渡文化发展的关系等问题进行初步讨论。
Paleosalinity of Tianluoshan Site is reestablished by mensurations and analyses of clay mineral, boron, strontium, barium, after sampling in a profile of Tianluoshan Site. The relative sea level changes are discussed according to the lab results. It turns out that there are at least three time periods of relative sea-level highstand not only before but also during and after Hemudu Culture in Tianluoshan Site. Based on previous researches and through studying several environmental elements comprehensively, the characteristics of environmental background and their relationships between human activities and development of Hemudu Culture are systematically discussed.
