内蒙古林西县井沟子西区墓地人骨的稳定同位素分析

Paleodiet studies using stable carbon isotopes from human bone:example from Jinggouzi cemetery,Inner Mongolia

井沟子遗址位于内蒙古林西县双井店乡敖包吐村井沟子自然村北,西北距林西县政府所在地林西镇约40公里,南距西拉木伦河8公里。遗址坐落于一条西北高、东南低的向阳坡岗上,背依高山,俯临河川。2002～2003年。

In this article,ten ancient human bones unearthed from the Spring and Autumn- Warring states period cemetery at the Jinggouzi site in Linxi county,Inner Mongolia were studied.we examine Jinggouzi human paleodiet using stable isotope ratios of carbon and nitrogen in bone collagen.Nitrogen isotope ratios of bone collagen show that Jinggouzi ancient inhabitants in primarily ate animal products with only a small amount of plant products,Carbon isotope ratios of bone collagen show that most plant products come from C_4 plant.
