中文摘要：

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，探讨了同位素和微量元素分析在古代人类食物结构研究中的应用问题。研究结果表明同位素分析结果能够揭示当时人的食物到底以C3植物、C4植物、食草动物、海产资源的哪个为主这一问题，而微量元素分析结果能够在同位素分析所分类的大类型中，进一步探讨具体的动植物种类。

英文摘要：

Based on the analysis of the data of carbon nitrogen isotopes and trace elements such as Sr, Ba Ca et al. of the two pieces of excavated human bones of late period of Dawenkou culture and period of Chunqiu and Zhanguo in Upper Shu River in Shandong province, the research applied the analysis of carbon nitrogen isotope and trac.e elements into the study of ancient diet. The results showed that the analysis of isotope could restore the main food component into such type as C3 plants, C4 plants, animals or sea food, furthermore the analysis of trace element could identify the concrete plant or animal.
