Abstract: Under the action of gravity, the powerful driving forces of recent tectonic movement affecting the studied plateau and adjacent areas are stemming from the crust of Qinghai-Xizang Plateau. Therefore, in Southwest China took place a flow of crustal materials toward the southeastern direction. Such flow possesses rather special nature, unlike the downhill sliding of the glacier. In the front of the flow can be found recent tectonic activities with different features due to the variations of resistance encountered. Moreover, the occurrence of earthquakes in Southwest China is also constrained by the material flow.The authors suggest that since the driving forces of recent tectonic activities in this area are in close relation to gravitational effect, the localized recent tectonic processes would be ascribed to the category of gravity tectonics.

摘要： 在重力作用下,青藏高原巨厚的地壳成为高原及其邻区现代构造运动的强大动力源。在其驱动下,我国西南地区存在着往南东方向运动的地壳物质流,它具有独特的运动方式,与冰川下滑运动有所不同。在地壳物质流动过程中,由于阻力的差异,可以表现出不同的构造活动性。西南地区地震的发生受到地壳物质流动的控制。西南地区现代构造运动的动力源与重力关系十分密切,因而可属于重力构造范畴。
