The Zayu River in the reserve is a major tributary of the Brahmaputra River in the lower reaches of the Brahmaputra River. The lowest point in the reserve is only 1,500 meters, while the main ridge lines of the mountains on both sides are mostly around 5,000 meters, with peaks over 6,000 meters in between. The mountainous landforms are vertically differentiated. The valley at the foot of the mountain is a zone of flowing water, and the valley is a canyon landscape with steep banks and steep banks. Alluvial fans and debris flow accumulation fans are common at ravine mouths. In the mid-mountain area between the forest line and the valley slope, there are many dense forests. According to relevant data, the forest coverage rate in this area reaches 54.6%, all of which are virgin forests, with a large proportion of mature and mature forests.
