Relationship between Physiography Stage-Tectonic Rhythm-Climate Cycle Coupling and Geological Hazard at the Three Gorges Area

Tectonic-physiognomy-climate cycle coupling is one of the focus of modern earth system science.A mass of geological facts suggest that geological hazards can be consanguineously related to tectonic,physiognomy and climate.Tectonic-physiognomy-climate cycle coupling in stage means the physiography stage-tectonic rhythm-climate cycle coupling,and dominates the conglomeration of geological hazards both on space and time.In this study we establish the coupling model of physiography stage,tectonic rhythm,climate cycle and geological hazards,based on the coupling and relationship between physiography stage,tectonic rhythm,climate cycle and effects which they have on the occurrence of geological hazards.Based on the geological data,we carry out a primary analysis of the relationship between the physiography stage-tectonic rhythm-climate cycle coupling and the occurrence of the landslides in the Three Gorges area.Besides,we also discuss on how to further this kind of research.
