摘　　要：目的：通过对陕西秦始皇陵区山任窑遗址出土的2200年前人下颌骨观察和测量，了解我国秦代人的下颌骨特征．方法：选取保存较完整的下颌骨49个，采用数显游标卡尺及0—360°游标万能角度尺对下颌骨进行三维测量，并记录其表面各标志性结构，结果用SPSS13．0软件进行统计分析．结果：首次报告了秦代人下颌骨的各项测量数据及非测量性状的研究结果，下颌骨的各项测量数据，除下颌角外，各年龄组之间均无统计学差异（P〉0．05）．颏孔位于第二前磨牙下方者居多，下牙弓形态主要以椭圆形为主．结论：为人类体质学和进一步研究人类下颌骨演化积累数据资料．AIM： To find out the characteristics of mandible of the people in Qin dynasty about 2200 years ago through the observation and measurement of mandible sample excavated from Emperor Qin Shihuang＇s Mausoleum. METHODS： Forty-nine well preserved samples were selected. Metric and non-metric studies were carried out respectively. 0 ～ 360°omnipotent angle ruler and digital vernial caliper were used for three dimension measurements. Non - metric traits were recorded by observation. Data obtained were analyzed by SPSS13. 0. RESULTS： All data of measurements by three dimensions were reported for the first time. No statistic differences were found among different age groups except mandibular angle （ P 〉 0.05 ）. The position of mental foramen was mainly under the second premolar, and there were more oval arch forms in mandible. CONCLUSIONS： The study provides some data for human anthropology and human mandible evolution.
