主　　题：Yalu Tsangpo River sediment deposits uneven uplift himalaya wide valley 

摘      要：The fluvial process of the Yalu Tsangpo River occurs concurrently with the uplift of the Qinghai-Tibet ***,the river exhibits unique features in morphology and sediment *** investigations were performed from 2009–2011and the depth of the interface between the sediment deposits and bed rock was detected with an electromagnetic imaging system(EH4)at 29 cross *** deposits were sampled along the Yalu Tsangpo valley from Xietongmen to the Yalu Tsangpo *** results show that a huge amount of sediment has been deposited in four wide valley sections because the uplift rate in these sections was lower than that in the downstream gorge sections over the past million *** 518 billion m3of gravel and sand have been stored in the high mountain river valleys,which has changed the V-shaped mountain river valley into a U-shaped wide river valley in the four *** the sections with high uplift rates the river bed is incised and has formed gorges and the Yalu Tsangpo Canyon.
