This paper focuses on the morphology of the distal tarsometatarsus of birds.The tarsometatarsi of 154 specimens of living birds belonging to 15 orders were measured although over 200 specimens were examined.

本文以鸟类的跗跖骨为研究对象，共观察了200余例有代表性的现生鸟类标本，并对其中15个目中的154例标本进行了多组数据的测量。

In this paper, 4 variables of the distal tarsometatarsus were also collected from 25 specimens of fossil birds belonging to 14 genera of Early Cretaceous birds from Western Liaoning in China. Analyses of these variables have also proven to be useful in distinguishing arboreal and terrestrial birds, and the result is generally consistent with a conclusion reached on the basis of other analysis, i.e. those based on the claw geometry and toe proportion.

通过对在中国已发现的25例中生代鸟类跗跖骨远端4个变量的统计分析，表明它们同样具有区别树栖和地栖鸟类的显著意义，而且分析的结果与参考鸟类其他特征（如爪的形态、脚趾的比例等）所得出的结论基本一致。

Research on the diversity of shape and structure of avian tarsometatarsus, not only did it present evidences to realize the ecological habit of birds of different species, but made the knowledge of functional behavior of avian hindlimbs perfect progressively also.

鸟类跗跖骨形态结构多样性的研究不仅为了解不同类型鸟类的生态习性提供证据，也使鸟类后肢骨骼的功能行为学得以逐步完善。
