| Abstract: | In this paper we investigate the sources of two kinds of forces to form the stress field in the lithosphere. These are the
drag force caused by mantle flow and the force system along plate boundaries. The results show that both forces control the
basic stress pattern in China and compressive stresses can fit with the stress patterns constructed by focal mechanisms,in-situ stress measurements in boreholes and that deduced from other geophysical and geological observation.
