摘要:
青藏高原被称为世界屋脊,第四纪地貌发育良好,是第四纪地貌学研究的良好野外素材.位于青藏高原东南缘的帕龙藏布流域是雅鲁藏布的一级支流,沿岸堆积多种成因的第四纪堆积物,主要包括冰碛物、河流阶地、泥石流堆积物和崩滑堆积.通过无人机航拍、高精度遥感影像、野外实测剖面、钻孔岩心和物探对索通平台第四纪堆积物成因进行详细的分析,得出以下结论:1)索通平台第四纪堆积体最初是由第四纪冰川作用形成的冰碛平台; 2)后期冰碛平台外侧边缘受帕龙藏布改造形成现今的五级阶地; 3)对冰碛平台边缘外侧阶地沉积物的沉积构造、阶地类型和陡
Abstract:
Quaternary geomorphology in Qinghai-Tibet plateau, known as the roof of the world, are good materials in the field of quaternary geomorphology research, Parklon Zangbo river basin in the South-Eastern margin of the Qinghai-Tibet plateau is tributary of the Yarlung Zangbo river basin, where quaternary sediments of various origins accumulate along the coast, mainly including moraines, river terraces, debris flow deposits and collapse accumulation.Through unmanned aerial photography, high precision remote sensing image, field measured profile, drilling core and geophysical prospecting, we analyze the genesis of the quaternary sediments of the Suotong platform and come to the following conclusions: 1)the quaternary sediments of the Suotong platform were originally formed by the quaternary glaciation; 2)the outer edge of the later moraine platform was transformed by Parklon Zangbo to form the present five terraces; 3)analysis to sedimentary structure, types of terraces and scarp height of the sediments on the lateral terrane terrace edge indicate that the terraces are mainly formed by climate change and the tectonic effect.
