摘要	The global heat flow is the surface representation of thermal processes within the earth's mantle. The long-wavelength pattern of observed heat flow closely resembles the plate tectonics and its most prominent feature is higher values along ocean ridge systems. Theoretically, to determine the thermal state of the Earth's mantle, the heat transfer problem and the mantle convection problem have to be solved simultaneously since they are coupled with each other. However, the development of global seismic tomography provides us with a possibility that, at least under certain assumptions, these problems can be decoupled from each other and solved separately. This allows us to calculate mantle flow velocities first based on the internal loading theory and then use the velocity field as the input to solve the thermal problem. In addition to the internal density anomalies, surface plate movements also excite mantle circulations and, under certain circumstance, they may dominate the structure of the mantle flow.
