青藏高原素有“世界屋脊”之称.其目前变动的水平位移达到l-3cm/a,这是全球大陆变动最强的地区,长期以来,高原的现代地壳运动的定量观测基本上局限于它的垂直运动分量,至今未得到该地区的大尺度地壳水平运动可信的实测结果. The Qinghai-Tibet Plateau is known as the “roof of the world.” Its current level of horizontal displacement reaches 1-3 cm / a, which is the strongest change in the global continent. For a long time, the quantitative observation of the modern crustal movement in the plateau has basically been confined to it Of the vertical motion component, so far no reliable measurement results of large-scale horizontal crustal movement in the area have been obtained.
