摘要

为研究泥石流灾害对西藏雅鲁藏布江林芝—加查段沿线的影响与危害

利用遥感(RS)和地理信息系统(GIS)开展了该段沿线泥石流源地物源提取及其分布特征的分析。研究结果表明

林芝—加查段沿线泥石流源地物源分布不均匀

物源分布受地层岩性、海拔高程及地形坡度影响。这些泥石流源地物源在冰川融水及冰川型泥石流过后更加发育

积累的松散物质更加丰富

使泥石流源地物源进一步复活并产生大量新物源

从而使沿线泥石流发生频率增高

规模增大。

Abstract

In order to study the impacts and hazards of debris flow disaster on the Linzhi—Jiacha section along the Yarlung Zangbo River in Tibet

remote sensing and geographical information systems techniques are used to extract information on the material sources in the debris flow origin areas along the Linzhi—Jiacha section and analyze the distribution characteristics of the material sources.Results from the study showed that the distribution of the material sources in the debris flow origin areas is not uniform due to the influences of formation lithology

altitude

and topographic slope.After glacier melting and glacier type mudflow

the material sources are more developed and the accumulated loose materials are more abundant

which further stimulates the material sources and produces a large amount of new material sources in the debris flow origin areas.Consequently

the frequency of debris flows along the river is raised and the scale of the debris flows is enlarged.
