In this paper we determine the global plate boundary segments with different width and calculate thelong-wave and the shor-t wave components of the stress fields. We thus discuss the relative contribut ion of the shor-twave components to the stress f ield and analyze the relat ionship between contributions and the relative mot ions of theplate boundaries. The main plate driven forces come from the slab pull (or slab suction) on the convergent boundaries,and the ridge push forces cannot be the only control forces on the stress style of plates. The collision forcesbetween two cont inental plate boundaries play an important role in their motions. Our study shows that the reasonablereference hal-f width of boundary is less than-00 km.
Key words： plate boundary segments; stress field; shor-t wave component
