英文摘要	We apply a kinematic simulation method to perform modeling for the global lithospheric stress field induced by mantle now. Both the internal density anomalies and surface plate movements drive the mantle circulation. Mande flow causes normal stress and tangential stresses at the base of the lithosphere, which affect or even lead to lithospheric stress field and lithospheric deformation. Our simulation shows that the agreement between predictions and observations is good in most regions. Most subduction zones and continental collisions, such as the circum-Pacific subduction zone and the collision zone between the India and Eurasia plate, are under compression. While ocean ridges, such as the east Pacific ridge, the Atlantic ridge and the east African rift, are under tension. And hotspots preferentially occur in regions where calculated stress is tensile. Calculated directions of the maximum horizontal principal compressive stress are in accord with observed principal stress directions in the mass except for some regions such as the northwest Pacific subduction zone and the Qinghai-Tibet Plateau. Our study shows that, mantel flow plays an important role in generating and distribution of the stress field within the lithosphere.
