摘　　要：通过对广西桂林甑皮岩和大岩遗址出土新石器时代早中期人和动物骨骼的碳氮稳定同位素分析和加速器质谱碳十四测年研究,可知新石器时代早中期的环境较稳定,以C3植物为主,有少量C4植物。先民主要摄取淡水类动物资源,早期人群在食物选择上高度集中,中期人群则更加多样,陆生资源显著增加。Carbon and nitrogen stable isotope analysis,together with AMS radiocarbon 14 dating of human and animal bone samples unearthed from the Zengpiyan and Dayan sites in Guilin,Guangxi,suggest a relatively stable environment dominated by C3 plants,supplemented by a small amount of C4 plants.Prehistoric populations mainly relied on fresh water resources,but significant dietary differences between the early and middle phase were detected.The diet of the early Neolithic population(n=6)was highly concentrated,while the diet of the middle Neolithic population(n=11)shows more diversity and utilization of more terrestrial resources.This transition in dietary spectrum is likely related to population structure,environmental adaptation,and shifting foraging ranges.
