The study on the block boundary’s driving forces and tectonic stress field of China mainland and its adjacent areas using GPS data

After reviewing the inversion study on the driving forces of China mainland and its adjacent areas, the inversion computation is made by means of genetic finite element method and covering complex method based on the displacement observations of the Crustal Movement Observation Network of China. The whole procedures of inversion study, including parameter selection, computation conditions, inversion analysis and interpretation, are given out in details. Then some conclusions are drawn: ailene1 the main driving forces acting on China mainland are still from the collision of Indian plate with Eurasian plate; ailene2 the driving forces of Pacific plate and Philippine plate are significant to the eastern China; ailene3 the back basin of Japan sea arc is continuously extending; ailene4 the forces from north prevent the northern motion of China.
