| 英文摘要 | The globle heat flow is the primary energy flow responsible for the dynamic of nature of our planet. In this study we investigate in a three dimensional spherical geometry frame, the generation and distribution characteristics of global heat flow on the basis of exploring thermal effects of density anomaly and platedriven mantle flows. Results show that the thermal effect of plate motion-driven mantle flow and its contribution to the observed heat flow is greater than that due to internal density anomaly (tomography based). Higher values of observed heat flow in mid-ocean ridge system could be accuounted for, to a great extent, by the thermal effect generated by the plate-driven mantle flow. Furthermore, the predicted average temperature as function of depth reveals the features of an isothermal core and two thermal boundary laters at the surface and the core-mantle boundary. An approximate thickness of 150km for lithosphere within which the temperature rapidly varies can be obtained. A mantle viscosity model, in which viscosity in the lower mantle is 30 times than that in the upper mantle, appears to fit data better. |
