摘　　要：河南淅川下寨遗址史前人骨遗存的碳氮稳定同位素分析结果揭示了不同时期史前先民的食谱特征。仰韶晚期先民(δ^(13)C=-10.2±1.4‰,δ^(15)N=9.4±0.5‰,n=19)以粟黍为主粮,与同时期中原先民相似;石家河文化时期先民(δ^(13)C=-13.6±2.1‰,δ^(15)N=9.5±0.9‰,n=28)呈现稻粟黍混合的食谱特征,水稻与旱地作物的氮同位素特征差异导致先民食谱特征内部出现明显差异;龙山晚期和二里头时期先民δ13C平均值为-9.9±1.2‰(n=21),表明粟黍重新成为当地主粮,食谱特征的内部差异也明显降低。这种现象说明,文化变迁深刻地影响了当地的农作物体系和先民食物结构。粟黍和水稻在先民食谱中的地位变化也反映了黄河流域文化与长江流域文化对该地区的交替影响。Stable carbon and nitrogen isotope analysis of human remains from the Xiazhai site revealed dietary features of pre-history populations dated to different periods.The Late-Yangshao individuals(δ^(13)C=-10.2±1.4‰,δ^(15)N=9.4±0.5‰,n=19)ate a millet-based diet similar to that of the contemporary people on the Central Plains.On the same site,the Shijiahe people(δ^(13)C=-13.6±2.1‰,δ^(15)N=9.5±0.9‰,n=28)ate both millet and rice,and their dietary features displayed evident variation because of the different nitrogen isotopic features between rice and dry crops.Millet played the role of main staple food again during the Late-Longshan and Erlitou period(mean δ^(13)C=-9.9±1.2‰,n=21).These results indicate that cultural transition had significantly affected the local agricultural system and human diet.The changing roles of millet and rice also reflect the alternating influences from the Yellow River culture and the Yangtze River culture.
