摘　　要：变形分解作用是描述总的构造应变变形如何分解到一定意义分量的一个运动学概念。变形分解作用形成的构造应变变形分量之间的分解可以是表现在应变场的不均一性,也可以是同一应变场的,还可以是表现在构造力学性质、变形机制等的差异。因此,作为一种运动学概念,它涉及多个构造应用领域,研究者建立了多种不同的变形分解作用运动学模型并讨论其控制因素。为构造变形分解作用的研究提供了一种系统思维的研究思路,有利于更系统的认识相关地质构造之间存在的联系。综述了国内外学者对变形分解作用的研究。Deformation partitioning is a concept describing how a total tectonic deformation is partitioned into some kinds of components. Those partitioned components may be expressed as heterogeneity of strain field, but they can also be happened in a homogeneous one. Furthermore, they may be a kind of representation of the difference in mechanics and deformation mechanism among various structures. As a kinematic conception, it is related to many applied fields of structural geology, and a variety of kinematic models were proposed and the factors controlling the process were discussed from physical and numerical models. Researches on deformation partitioning provide a systematical ideology for the study of structural geology, and it is useful in the systematical study on the relationships among the different geological structures.
