摘要/Abstract

摘要： 本文以新疆巴里坤东黑沟遗址出土的人骨为研究对象, 测定骨中的碳、氮同位素比值, 揭示该地区古代先民的食谱特征, 探索当时人们的生活与生产方式、经济形态等历史信息。研究结果发现: 人骨样品的δ13C值分布在-18.96‰~-17.74‰范围内, 样品的δ15N值均较高, 分布在12.64‰~14.33‰范围内, 表明新疆巴里坤东黑沟遗址先民的食物结构是肉类食物在日常饮食生活占有相当大的比例。根据考古发掘出土的动植物遗存, 肉类的获取应来源于驯养的牛、羊等或部分狩猎所得的鹿等动物, 植物性食物主要来源于大麦、小麦等C3类作物, 这与其生活的环境和以游牧为主, 农业和狩猎为辅的经济形态密切相关; 男性与女性的食物结构相同。

Abstract: In this article, the ratio of C and N stable isotopes in human bones was analyzed to reconstruct diet and determine lifeway, mode of production and economic mode of ancient peoples who lived at the Dongheigou site, Ba Li-kun County, Xinjiang Autonomous Region. Stable isotopic analysis of 11 bone samples gives the following results: -17.74~-18.96‰ for δ13C and ?12.64~14.33‰ ?for ?δ15N. This data shows that the diet of these people included a large percent of meat and some C3 plants, which suggests an economic mode dominated by nomadism and supplemented by cultivating agriculture and hunting. Based on excavated animal and plant remains the food obtained from the pasture animals such as cattle and sheep or deer, and C3 plants such as barley and wheat. There was no difference in diet between males and females.
