It surrounds the Kumkol Basin, an endorheic basin (no outlets to the sea) in the western third of the Altyn-Tagh mountains ("Altun Shan").[2] The reserve is sometimes referred to as the "Arjin Mountains Nature Reserve", or "Aerjinshan".[3] The reserve covers the southern portions of Qiemo County and Ruoqiang County of Bayingolin Mongol Autonomous Prefecture in Xinjiang. TopographyThe Altun Shan Reserve is an elongated triangular area on the southern edge of the Taklamakan Desert, just south of the Tarim Basin. The reserve occupies the "V"-shaped region between the southern slopes of the Altun Shan range on the north and the northern slopes of the Kulun mountain range on the south. The eastern third of the reserve is the Komkul Basin, an arid plateau at an altitude of 4,500 meters. The reserve measures about 800 km west-east, and 200 km north-south. There are no permanent towns or roads in the area. There are three large lakes in the Kumkol basin of the reserve: Lake Ayakum, Lake Aqqikkal, and Lake Jingyu. All are saline ("salt lakes"). The northernmost, Lake Ayakum, is at an altitude of 12,685 feet and has an area of 283 sqmi. Its depth reaches 74 feet. To the west of Lake Ayakum is Lake Aqqikkal, at an altitude of 13,940 ft, and which is 16 miles across. Lake Jingyu is the southernmost.[4] ClimateBecause of its high altitude (over 4,500 meters above sea level) and arid location thousands of kilometers from any ocean and in the rain shadow of the Himalayas and other mountain, the climate of the reserve is "Cold desert climate" (Köppen climate classification "BWk" ). This climate is characterized by hot, dry summers, and very cold, dry winters. At the highest elevations, the climate is a Polar climate (Koppen "ET") with cooler summers but still cold and dry in the winter. EcoregionMost of the reserve is in the "North Tibetan Plateau-Kunlun Mountains alpine desert" ecoregion, an area characterized by extreme aridity, high winds, and very cold winters.[5] The northeast of the reserve around Lake Ayakum is in the Qaidam Basin semi-desert. Qaidam is the Mongolian word for 'salt', and the region is one of gravelly desert and some saline meadows and salt lakes.[6] Temperatures reach an average high of {{convert|56.5|F|C}} in August, and average lows of {{convert|-18.6|F|C}} in January. There is little to no precipitation in most years, but some frost cover.[6] Flora and faunaThe reserve provides space outside of human development for some of the largest herds of hoofed in Asia: the vulnerable Tibetan wild yak (Bos mutus) (an estimated 10,000), wild ass (30,000), and Tibetan antelope (Pantholops hodgsonii) (up to 75,000).[7] The area is also an important habitat for the endangered Kozlov's Pika, and the relatively common Ladak pika.[8] There are also small populations of dholes (Wild Asiatic dogs).[9] AccessAccess is restricted, and high permit fees are required to enter. The soil is fragile and there are no permanent roads. See also
