Yushu Prefecture occupies most of the southwestern third of Qinghai, with the exception of the province's extreme southwestern corner, which is an exclave of the Haixi Mongol and Tibetan Autonomous Prefecture. Almost all of the prefecture is located in the uppermost part of the basins of three of Asia's great rivers - the Yellow River, the Yangtze, and the Mekong, although in the remote areas of the far west of the prefecture, and along its northern borders, there are some endorheic basins as well. A significant portion of the prefecture's territory is incorporated into the Sanjiangyuan National Nature Reserve, intended to protect the headwaters of the three great rivers. Most of the prefecture's population lives in its southeastern part: primarily in the valley of the upper Yangtze, and some also in the valley of the Mekong. The highlands away from these two rivers, as well as the western part of the prefecture, have very little population.

History and traditional culture
; Monasticism township Yushu prefecture is rich in Buddhist monasteries. Being a constituent of the former Nangchen kingdom, the area was, for most of the time, not under domination by the Dalai Lama’s Gelugpa order in Lhasa. The different balance of power in this part of Kham enabled the older Tibetan Buddhist orders to prevail in Yushu. Of the 195 pre-1958 lamaseries only 23 belonged to the Gelugpa. An overwhelming majority of more than 100 monasteries followed and still follow the teachings of the various Kagyupa schools, with some of their sub-sects only found in this part of Tibet. The Sakyapa were and are also strong in Yushu, with many of their 32 monasteries being among the most significant in Kham. The Nyingmapa’s monastic institutions amount to about the same number, while the Bönpo are only met with in one lamasery they share with the Nyingmapa. Prior to collectivization in 1958, the entire monastic population of present-day Yushu TAP amounted to more than 25,000 Buddhist monks and nuns, with approximately 300 incarnate lamas among them. On the average about three to five per cent of the population were monastic, with a strikingly higher share in Nangchen county, where monks and nuns made up between 12 and 20% of the community.
