本文应用稳定同位素分析技术对内蒙古赤峰市大山前遗址夏家店上层文化"祭祀坑"出土人骨中的C、N同位素比值进行了测定。结果显示:大山前遗址夏家店上层文化时期先民食物结构以C4类植物为主,很有可能来源于粟、黍和稷,肉类食物在食物结构中占有一定的比例,暗示出饲养业和畜牧业在当时的经济生活中已经占据重要的位置。本文的研究为复原内蒙古东南部地区特别是赤峰地区青铜时代人群的经济生活模式提供了重要的科学依据。
The so-called ‘sacrificial pit'at the Dashanqian site in Chifeng town,Inner Mongolia,was excavated in1998. Since Dashanqian is one of the most important Bronze-age sites in the Chifeng area,we analyzed the paleodiet of the human remains at Dashanqian using stable isotope ratios of carbon and nitrogen in bone collagen and present the results here. The nitrogen isotope ratios of bone collagen show that the Dashanqian inhabitants consumed certain animal products. Meanwhile,the carbon isotope ratios of bone collagen show that most plant products came from C4 plant.
