摘　　要：通过对山东广饶新石器时代大汶口文化墓地 90年代发掘的 61具成年头骨进行小变异特征出现率的观察与统计并在此基础上进行聚类分析和主成分分析研究认为 ,广饶人群的蒙古人种地区类型属于东亚类型。同时本文结果提示 ,在明确蒙古人种地区类型的主成分分析研究中 ,贡献率较大的三个小变异特征为下颌舌骨肌线桥、舌下神经管二分、眶上孔 。The human skeletons studied in this article were buried ca. 5000Bp and unearthed at Guangrao Neolithic Site of Shandong. We observed 61 human skulls of them in eight minor skeletal variants and calculated the frequency of their occurrence. The results from the cluster analysis and the principle component analysis based on the mean measure of divergence(MMD) of eight groups of Mongoloids show that the Guangrao skeletons belong to the East Asian Mongoloid group and we also find that mylohyoid bridge, double hypoglossal canal and supraorbital foramen contribute more to differentiate the geographical types of Mongoloids.
