内蒙古巴彦淖尔市纳林套海汉墓出土人骨的稳定同位素分析

稳定同位素分析技术近年来发展为复原古代民族食物结构、社会经济模式的有效手段。本文应用该技术对内蒙古自治区纳林套海汉代墓葬出土人骨中的C、N同位素比值进行了测定。结果表明, 纳林套海汉代居民日常饮食结构中保持着非常高的动物性食物摄入, 植物类食物的摄入中以C4类植物为主。结合其他相关研究结果, 我们认为西汉王朝通过实施移民屯垦和属国等政策, 大力推动了河套地区的农业和畜牧业生产, 改变了河套地区原有的经济模式和人们的饮食结构。本文的研究结果可以为复原汉代北部边疆的经济模式研究提供有益的线索和证据。

Stable Isotope Analysis of Human Bones from Nalintaohai Cemetery,Baiyanaoer, Inner Mongolia

The Nalintaohai ancient site, located along a bend in the Yellow River in Bayanaoer, Inner Mongolia, is very important site of the Han Dynasty. In this study, we examine Nalintaohai human paleodiet using stable isotope ratios of carbon and nitrogen found in bone collagen. Nitrogen isotopic ratios of bone collagen show that the Nalintaohai inhabitants ate plenty of animal products and some plants. Carbon isotopic ratios show that the human diet is composed of C4 plants. It is clear that these inhabitants tried to establish stock raising and farming, which created a large degree of social wealth. By comparing stable isotopic data from different times and sites throughout the southern part of central Inner Mongolia, C4 consumption still played a minor ?role ?in ?human ?diets,? while? Han ?Dynasty ?human ?δ15N values are higher than from other periods.
