Administratively, the range is in the Nagqu Prefecture of the Tibet Autonomous Region, with the central section extending into nearby of Tanggula Town and the eastern section entering the Yushu Tibetan Autonomous Prefecture of Qinghai province.
The Tanggula is the source of the Ulan Moron and Dangqu Rivers, the geographic headwaters of the Yangtze River. The range thus functions as a dividing range between the basin of the Yangtze in the north and the endorheic basins of north-eastern Tibet in the south.Overview
