摘　　要：目的:探讨太行山猕猴骶骨指数性差.材料和方法:成年猕猴骶骨标本55例(雄17,雌38).选择骶骨5个线性变量和4个指数变量;统计处理采用ANOVA、多元判别分析和二元逻辑回归分析.结果:大部分骶骨线性变量存在性差(P<0.05),雄性大于雌性;猕猴骶骨相对宽指数性差显著(P<0.01),雌性大于雄性.多元判别分析性别正确判别率为78.2%~87.3%.逻辑回归分析性别正确判别率为83.6%~87.3%.结论:骶骨变量性差显著,骶骨体长和骶骨相对宽性别判别的能力较强.Objective： To study sexual dimorphism of sacrum in Macaca mulatta from the Taihang Mountains. Materials and Methods： Sacrum specimens of 55 mature Macaca mulatta （17 males and 38 females） were examined. The measurements included 5 liner variables of the sacrum and 4 index variables. ANOVA, multivariate discriminant analysis and binary logistic regression analysis were used for statistical analysis. Results： Most of the liner variables were sexual dimorphism （P〈C0. 05） and the variables values were higher in males than in females. The relative widths of sacrum, which were sexual dimorphism （P〈C0. 01）. were larger in females than in males. The accuracy of multivariate discriminant analysis for sex discrimination ranged from 78. 2% to 87. 3%. While by using logistic regression analysis, the accuracy ranged from 83. 6% to 87. 3 % . Con -clusion： There are significant difference in sacral sexual dimorphism. Additionally, the sacral lengths and relative widths of sa-crum are important parameters for sex discrimination.
