Abstract：Development of hot dry rock geothermal energy under the guidance of continental dynamics and earth system dynam-ics plays a key role in the ongoing energy revolution and industrial revolution.However,theoretical study on the hot dry rock geology is still very weak.In this paper,we discuss the definition of hot dry rock from the perspectives of geology and econom-ics,propose a comprehensive classification of geothermal energy based on basin-orogen thermal tectonic system,and analyze the tectonic and petrological system of hot dry rocks in the solid and semi-solid rheological behavior according to rock rheology and tectonophysics.Under the guidance of four-dimensional non-uniform rheological property of active basin-orogen tectonic system,the spatial distribution and mechanism of hot dry rocks are discussed.It is suggested that the theories of earth system dynamics should be integrated in theoretical and applied studies of hot dry rock within the framework of related earth resources,geo-hazards,geoenvironments and engineering geology.In addition,an integrated exploration,assessment and development of hot dry rock geothermal energy should be carried out in the North China,the Tibetan plateau and its adjacent areas,the coast regions of Southeast China and Taiwan,which respectively belong to four different types of tectonically active geothermal units.
