中文摘要：

本文以甘肃礼县西山遗址早期秦人的遗骸资料作为主要研究对象，以牙齿磨耗、龋病、生前牙齿脱落、上下颌骨表面骨质隆起等指标作为主要观察内容，与国内外相关样本组作对比分析；与此同时，结合食谱分析结果，西山先民饮食状况较为复杂多样，总体上以肉食居多，植物性食物也占一定比例；推测早期秦人的经济模式应为农牧兼营的混合经济模式。

英文摘要：

Parafunctional and other tooth wear, caries and antemortem tooth loss, as well as other oral health indicators and cultural-related characteristics were studied on dental remains dating to the Pre- Qin period from the Xishan site, Lixian County, Gansu Province. Based on dental comparisons with other available samples from other ancient people in China and abroad, our results indicate that the dietary structure of the Xishan people was polyphagous and that their subsistence strategies were mixture of herding and agriculture.
