英文摘要	Based on fundamental equations governing thermal convection and taking features of mantle convection, especially self-gravitation and the non-linear effects of advective heat transportation, into account, this paper presents an appropriate numerical simulation method for solving mantle convection problems in which the observed long wavelength geopotential anomalies and the surface velocity field up to degree 8 are taken as the restrictions. The mantle is assumed to behave dynamically as a self-gravitating, incompressible Newtonian viscous fluid shell with spherically symmetric viscosity structure (a value of 10(21) Pas in the upper mantle and 10(22) Pas in the lower mantle). The PREM Earth model is used as a reference hydrostatic model. Using the technique developed by Backus, the momentum, energy, continuity and Poisson equations are simultaneously converted to a set of non-linear ordinary equations which are solved by means of the Born approximation and the multi-point shooting method.
