On the basis of tectonic analysis on stratification, block and stage of continental tectonics,this paper employs dynamic analysis method of tectonic time-space correlation to deal with that the fault block tectonics including some basic types such as uplift block, subsidence block and rotation block and layered tectonics showing different composition, strength and rheology are basic pattern of continental tectonics. During tectoinc activity, large amount of substance migration occurs in laminar flow and uplift-depression tectonics, and forms dynamic cycle system. Heat dominates the lower level of continental crust and result in the flow of viscoplastic and ductile substance along the ductile flow layer from mantle burgle area to mantle depression area, stress dominates the upper level of continental crust,and extension, and compression and shearing tectonic regimes related to the laminar flow of lower crust control the formation and evolution of fault block tectonics.
