Abstract:Aeolian sand landform in the Yarlung Zangbo river valley can be divided into 4 classes and 21 types, among them, aeolian deposition form can be further divided into two sub types at valley bottom and at valley slop. The area of whole aeolian sand landform or sandy land in the valley is 1 929.946 km 2. Sand resource ,wind froce and suitable place are the fundamental conditions for aeolian sand landform formation in the valley. In general view, aeolian sand landform distributes along the valley discontinuously. Their development are mainly controlled by wind and water froces alternatively in a year. In different parts of the valley, sand dunes have different patterns, but in small similar geomorphic locations they have similar pattern and combination character.
Keywords:Yarlung Zangbo river valley\ Aeolian sand landform\  Classification system\ Forming fundamentals\ The processes of development
