摘　　要：[目的]探究形态测量学方法在蚁科昆虫分类中的应用价值。[方法]采用因子分析、主成分分析和系统聚类的统计分析方法进行中国盘腹蚁属19种蚂蚁的形态测量学研究。[结果]4个主成分胸长(MSL)、头宽(HW)、腹柄长宽比(LPI)和腹柄长高比(DPI)有较高的载荷值,可综合反映其他14个变量,其主成分得分散点图能够明显区分该属19种蚂蚁;聚类分析可将19种盘腹蚁聚成4分支,第一支与第二亲缘关系最近,与第四支最远,其结果与主成分的分散点图的聚类情况以及形态特征分类结果基本一致。[结论]形态测量学方法对蚁科昆虫的分类学研究具有很好的应用价值,具有重要应用前景,可为物种分类鉴定提供新的方法。[Objective]To explore the application of morphometry in the classification of Formicidae.[Methods]Factor analysis,principal component analysis and systematic clustering statistical analysis were used to study the morphometric characteristics of 19 species of ants from the genus Aphaenogaster in China.[Results]The four principal components,including thorax length(MSL),head width(HW),peti-ole index(LPI)and petiole index(DPI)had high loading values,which could comprehensively reflect the other 14 variables.The scatter plot of the principal components could clearly distinguish 19 species of this genus.The results of cluster analysis showed that the 19 species of the genus Aphaenogaster could cluster into four branches.The first branch is closest to the second branch and the farthest from the fourth.The results were basically consistent with the clustering situation of the scatter diagram of principal com-ponents and the classification results of morphological characteristics.[Conclusion]The research method of morphometry has a good application in the taxonomic study of Formicidae,and has an important applic-ation prospect,which can provide a new method for species classification and identification.
