为探讨新疆巴里坤东黑沟遗址动物的食性特征、先民对动物资源的利用方式,测定了遗址发掘出土的马、牛、羊、狗、骆驼、鹿等动物骨骼中的碳氮同位素。结果显示:同一动物个体不同部位骨骼中δ~(13)C和δ~(15)N值基本接近;东黑沟遗址的马、牛、羊、鹿、骆驼等草食性动物以C_3类植物为主要食物来源;狗的食谱中肉食来源占有较大比例;两个骆驼标本显示氮同位素比值较高,这可能与其生长环境和代谢有关。结果分析表明该遗址马、牛、羊可能以放养和固定喂养相结合的方式,狗主要是家庭喂养的方式被先民利用,人们还进行狩猎和一定的农业生产活动。
In order to explore the feeding characteristics of animals in Dongheigou site in Balikun, Xinjiang, and the utilization methods of animal resources by predecessors, the carbon and nitrogen isotopes in the bones of animals such as horses, cattle, sheep, dogs, camels and deer excavated at the site were determined. The results showed that δ ~ (13) C and δ ~ (15) N values in different parts of the same animal were close to each other. The herbivores such as horses, cattle, sheep, deer, The main source of food was the large proportion of meat in the dog’s diet. The two camels showed higher nitrogen isotope ratios, which may be related to their growth environment and metabolism. The results show that the site of the horse, cattle and sheep may be a combination of stocking and fixed feeding, the dog is mainly used for family feeding by the ancestors, people are also hunting and some agricultural production activities.
