Abstract: By using Shao Xiangqing’s methods (1985), a measurement statistics and analysis of some mandibular variables of Macaca mulatta in Taihang Mountains was made. Furthermore, biomechanical scaling and allometric analysis was carried out and the results showed, on the one hand, the mandibular variables are highly sexual different. The length of mandible in male is longer than in female, and the length from posterior border of the mandibular condyle to the central section of M₁ and to the under-minipeak of M₃, the height of the mandibular branch is relative smaller in male than in female. On the other hand the length and width of mandibular condyle the height and width of mandibular body and the union length of mandible are strengthened in male then in female, thus , the ruminate forces get increase . This is closely related with the ecological strategy in Macaca mulatta in Taihang Mountains. There has a comparison among the results of this paper to the rhesus macaque in other area in China, and showed that there were evident differences among them.
