摘要: 根据黑叶猴(Presbytis francoisi)解剖标本的测量数据,用几何方法绘制出整体外形结构图,用R聚类分析结果找出了所测变量之间的相互关系;Q聚类和三维空间模式结构展示了黑叶猴外形整体结构与蜘蛛猴、食蟹猴,长臂猿、大猩猩和黑猩猩之间的相互关系。结果表明,在所测的23项变量中,由5个小聚类组成:与个体大小相关的变量、与前肢结构相关的变置、与后肢结构相关的变量、与颅骨结构相关的变量和臀部结构,在这些变量中,臀部宽与其他变量表现了极弱的相关关系。黑叶猴的外形整体结构与其他几种灵长类比较,更接近于食蟹猴和长鼻猴,其次接近于蜘蛛猴。因此从外形整体结构相似性分析,黑叶猴的运动与食蟹猴、长鼻猴和蜘蛛猿具有某些相似处。

Abstract: 23 variables were measured and 13 indices calculated on the external body of franceis' leaf monkeys in order to analyse the body proportion.Diagrammatic representation
of geometrie structure was shown.with R cluster analysis,the relationships between variables were constructed and using Q cluster and three -dimensional model,the relationshipsof the body proportion between francois'leaf monkeys and those of other primates were illustrated. The results gave some aspects,that is within 23 item of the variables.theycan be separated into 5 small clusters,which deal with body size,forelimb.hindlimb,crania and hip.The interesting thing is the hip width which is most weakly correlated with other variables.W ith regard to full body proportion,that of
the francois'leaf monkeys is more similar to those of the macaque,proboscis and spider monkeys.So even if the valid information about the locomotion of francois'leaf monkeys is deficient, we speculate that,when they move in the trees and ground,locomotor pattern of the francois'leaf monkeys is similar to those of the macaque,proboscis and spider monkeys on some ways.
