【摘要】 印度洋板块与欧亚板块的俯冲碰撞造就了横亘欧亚大陆南部边缘的阿尔卑斯-喜马拉雅造山带,喜马拉雅山脉的拔地而起成为印度洋暖湿气团北进青藏高原的屏障,加强了印度、孟加拉地区高强度的降水过程,导致经向河流的溯源和袭夺,并切穿喜马拉雅山主峰山脊逼近雅鲁藏布峡谷,举世瞩目的"大拐弯"就是布拉马普特拉河溯源、袭夺雅鲁藏布江所致。如今,这些经向河流峡谷成为暖湿气流北移的通道。本文提出,应用地质规律进行人工干预,有利于青藏高原生态环境的改善。更多还原

【Abstract】 The Alps-himalayas orogenic belt which lies across the south edge of Eurasia formed by subduction-collision of the Indian plate and Eurasian Plate.The Himalaya was so high that it became the barrier of warm and humid air mass northward to Qinghai-Tibet Plateau.It made the precipitation of India and Bengal strengthen and resulted in meridional river tracing to and capturing its source,and its main peak was cut through and approached the yalutsangpu Grand Canyon directly.The Big Bend of the Yaluzangbu river was formed just as Brahmaputra rivers han traced to and captured the source of yaluzangbu river. Nowadays,these rivers become the channel of warm and humid air mass from south to north.Based on the research,this paper points out that if we adopt the manual intervention according to the geological law,the ecological environment of Qinghai-Tibet Plateau will be improved.更多还原
