山东沭河上游出土人骨的食性分析研究

本研究通过对山东沭河上游大汶口文化晚期及春秋战国时期 2块人骨的碳、氮同位素分析和无机成分的锶、钡、钙等微量元素分析 ,恢复了当时人的食物结构。结论有以下两点 :1 由同位素分析可知 ,本地区贫民老百姓的食物在大汶口晚期时以C4植物为主 ,大约占 6 5 1 %的比例。此时期的食物结构存在贫富差异 ,富有者的食谱主要以C3植物为主 ,大约占 6 6 4 %的比例。 2 通过对小朱家村遗址出土的 1块人骨样品的微量元素分析 ,反映出同位素分析所表明的C3植物 ,除了少量种植的稻米外 ,可能还包括胡桃属、榛属、栗属、豆科等采集植物。

On the Diet of the People Represented by the Human Bones Unearthed from the Upper Shuhe River Valley in Shandong

Based on the isotope and trace element analysis of two pieces of human bones from the late Dawenkou culture and the Spring and Autumn period at Upper Shu River valley in southeast Shandong province, this paper tries to reconstruct the diet structure of the ancient human beings of the area. It argues that a gap of food structure exists between poor and rich people, The poor people of the late Dawenkou culture might rely on C 4,plants by 65.1 percent in food, while the nobles might have more C 3 plants by 66.4 percent in food. It further points out that the C 3 food, besides a small amount of domesticated rice, might have included some collected hazels, chestnuts and walnut etc.
