On the basis of total 822 heat flow measurement in the continental area of China, the deep geothermal characteristics of lithosphere of the major tectonic units was studied, which includes the temperature at 40 km depth, the thickness of thermal lithosphere, the cumulated strength and effective elastic thickness (EET) of lithosphere and so on. The results exhibit significantly lateral heterogeneity for heat flow pattern, thermal state and rheological features of lithosphere in China, which resulted from the Cenozoic tectonothermal activities related to the Pacific subduction as well as the collision between India and Asia. According to heat flow values and deep geothermal characteristics, three large scale thermo tectonic domains, i.e. Eastern, Central and Western domain, can be identified in the continental area of China.
