摘要: 西藏高原东南部山区,是我国现代冰川,尤其是海洋性冰川最发育的地区。该区特殊的地质地貌过程和冰川作用,形成了独具特色的冰川泥石流。这一突发性的自然灾害,成为高原隆起对自然环境和人类活动影响的明显标志之一。

Abstract: The mountainous regions in south-eastern Qinghai-Xizang Plateau is a region where existing glaciers (especially the monsoon maritime glaciers) are very well developed. The physical geographical environment and glaciation peculiarities in this region are the causes for the development of its unique glaical mud-flows.The distribution of glacial mud-flows is concentrated in the gullies of both sides of Polung Zangbo, Yigong Zangbo, the Dongjiu He and the Niyang He where lies the big bend of the Yarlung Zangbo Jiang in the south of the eastern section of the Nyainqentanglha Shan, and corresponds to the distribution of the monsoon maritime glaciers. Guxiang Gully on the right bank of Polung Zangbo may be taken as a typical example of the glacial mud-flows in the region. According to the data collected from three surveys and local observations made in the 60’s and the 70’s, the authors attempt to sum up the modern process of development and the characteristics of glacial mud-flows in Guxiang Gully.
