Shuanghu County, also transliterated from Tibetan as Tsonyi County[3] [4] [5] or Co Nyi County[6] [7] (;), is a county under the jurisdiction of the prefecture-level city of Nagqu, in the northernmost part of the Tibet Autonomous Region, China. It was formed in 2012, combining the territory of the former Shuanghu Special District with the eastern half of Nyima County. Much of the county is within the Changtang area.
Both Tibetan and Chinese name translates to "twin lake" or "two lakes", the two lakes referred to as Khangro Lake (khang ro tshwa kha) and Rêjo Lake (re co tshwa kha) respectively.Shuanghu County is at very high elevation, mostly above 5,000 meters above sea level, and very sparsely populated (averaging around 0.12 people per square kilometre, but concentrated in the southern portion of the county). The vast majority of its population practices nomadic pastoralism (mostly goats and sheep).[8] The climate is very rough, cold and dry. There is a weather station in Shuanghu, established in 1999,[9] which on average measures negative temperatures (Celsius scale) throughout the year. The highest temperature on record is +2.3 °C (July 2000), the lowest −62.4 °C (January 2006).
The county has one town and six townships:
