摘要
本文就主分量分析(PCA)的基本原理,运用发展过程及在动物分类学上的应用作了阐明。并以亚洲疣猴类5个属为例,利用其面颅和颅骨的6项变量进行分析,且叙述了PCA的主要计算过程。结果说明,在分类过程中,主要是面颅的凸度和宽度结构起贡献作用。
This paper demonstrates the basic discipline, development of principal components analysis (PCA) and it's utilization in classification of animals. 6 craniofacial and cranial variables coming from 5 genera of Asia colobines, including Rhinopithecus, Presb-ytiscus,Presbytis Pyga thrix and Nasalis,were taken as exaples. The results showed that craniofacial structure is dominant in classification of Asia colobines. The significant craniofacial and cranial morphological differences exist between Presbytis and Nasalis; Rhinopithecus and Nasalis; and between Rhinopithecus and Presbytis.
