| 摘 要： | 自20世纪60年代以来，大陆岩石圈流变学取得了较大的进展，理论和应用研究不断深入.理论上，人们不仅认识到在构造运动中岩石圈介质是流变体而非简单的刚体性和弹性体；并利用矿物和岩石的实验结果提出了岩石圈流变分层的概念，建立了一维流变模型；进而用流变的观点解释了一些具体构造现象，而且开始了三维流变结构的研究，提出了岩石圈流变结构的横向分块纵向分层的观点.应用上，人们已从把流变强度曲线简单地运用于运动学或动力学模型的阶段，进入了在三维空间中定量研究地球动力学问题的阶段.随着岩石圈流变学研究的深入及大陆岩石圈的复杂性，新的问题也不断涌现.

| Abstract: | A great deal progress has been made in the study of the rheological structure of the continental lithosphere since 1960's,not only in theory but also in the application.With such great progress it has become known that the lithosphere is the rheological body other than the rigid or the elastic one.Based on the experiments on the rocks or the minerals in the lithosphere,the concept of rheological stratification and the 1-D rheological model for the lithosphere are constructed,with which some tectonics are explained successfully.Furthermore,3-D rheological structure of the lithosphere are studied in recent years,from which it can be seen that the rheological structure is layered in the vertical direction,but the thickness and the depth of each layer varies horizontally.Based on the 3-D rheological structure of the lithosphere,people have begun the geodynamic study in 3-D space,other than the simple usage of the rheological strength envelopes in the kinematics model and dynamic model.However,more and more new problems appear at the same time because of the development of the rheology of the lithosphere and the complexity of the lithosphere. |
