高原指海拔较高、地表较平坦或呈波状起伏,有较广阔的面积,边缘通常以陡崖为界的地区。根据高原的形成原因,可以将高原分为隆起高原、熔岩高原和风积高原等几种类型,其中隆起高原是最主要的成因类型。一、隆起高原这里的隆起高原是指经过地质历史上的地壳运动,地壳隆起形成的高原。以青藏高原为例,在古生代末期,青藏高原地区还是横贯欧亚大陆南部的“古特提斯海”(从西南欧和非洲北部边缘经小亚细亚、喜马拉雅山脉到马来半岛)的一部分,其南北两侧是两大古陆,南侧 High altitude refers to the high altitude, the surface is relatively flat or undulating, with a broader area, the edge usually steeply bounded areas. According to the formation of the plateau, the plateau can be divided into several types of uplift plateau, lava plateau and aeolian plateau. The uplift plateau is the most important type of genesis. First, the uplift of the plateau Here refers to the uplift of the geology of the crustal movement, the formation of the plateau uplift. Taking the Qinghai-Tibet Plateau as an example, at the end of Paleozoic, the Qinghai-Tibet Plateau is still part of the “Gut Tethys Sea” across southern Eurasia (from the northern margin of South Western Europe and Africa through Asia Minor, the Himalayas to the Malay Peninsula) Its north and south sides are two ancient land, south side
