It is under the administration of Haixi Mongol and Tibetan Autonomous Prefecture. Da Qaidam has two subdivisions: the Town of Qaidam ({{lang|zh-hans|柴旦镇}}), also called Da Qaidam ({{lang|zh-hans|大柴旦镇}}), and the Town of Xitieshan ({{lang|zh-hans|锡铁山镇}}). The former is the administrative center of Da Qaidam and has an altitude of {{convert|3174|m|abbr=on}}.[1] China National Highway 215 and China National Highway 315 pass through Da Qaidam and meet here. Yinmaxia railway station and Xitieshan railway station on the Qinghai–Tibet Railway are located in the Administrative Committee of Da Qaidam.[1]GeographyDa Qaidam borders Delingha to the east, Lenghu to the west, Golmud across Lake Qarhan ({{lang|zh-hans|察尔汗盐湖}}) to the south, and Jiuquan (Gansu) to the north, and is part of the northern Qaidam Basin. Similar to neighbouring Golmud, Da Qaidam has a arid climate (Köppen BWk), with long, cold winters, and warm summers, although due to its location further north and elevation more than {{convert|350|m|-1}} higher than Golmud, its climate is also subalpine in nature. The monthly 24-hour average temperature drops to {{convert|-13.4|°C|1}} in January and rises to {{convert|15.5|°C|0}} in July, while the annual mean is {{convert|1.88|°C|1}}. Precipitation is very low, totaling only {{convert|83|mm|2|abbr=on}} per annum, falling on 35 days, most of which are during the summer. With monthly percent possible sunshine ranging from 65% in July to 82% in October, the area receives 3,257 hours of bright sunshine annually. {{Weather box|location = Da Qaidam (1971−2000) |metric first = Y |single line = Y |collapsed = |Jan high C = −4.1 |Feb high C = −0.6 |Mar high C = 4.6 |Apr high C = 10.4 |May high C = 15.8 |Jun high C = 19.4 |Jul high C = 21.8 |Aug high C = 21.4 |Sep high C = 16.4 |Oct high C = 9.7 |Nov high C = 2.6 |Dec high C = −2.2 |Jan low C = −21.1 |Feb low C = −17.0 |Mar low C = −10.8 |Apr low C = −5.0 |May low C = 1.2 |Jun low C = 6.0 |Jul low C = 8.8 |Aug low C = 7.7 |Sep low C = 2.0 |Oct low C = −6.1 |Nov low C = −13.6 |Dec low C = −18.7 |year high C= 9.6 |year low C= -5.5 |year high F =49.3 |year low F = 22.0 |Jan precipitation mm = 2.1 |Feb precipitation mm = 1.9 |Mar precipitation mm = 2.9 |Apr precipitation mm = 2.3 |May precipitation mm = 8.9 |Jun precipitation mm = 21.4 |Jul precipitation mm = 21.8 |Aug precipitation mm = 14.4 |Sep precipitation mm = 4.7 |Oct precipitation mm = 0.8 |Nov precipitation mm = 0.6 |Dec precipitation mm = 1.2 |year precipitation mm= 83.0 |unit precipitation days = 0.1 mm |Jan precipitation days = 2.5 |Feb precipitation days = 2.0 |Mar precipitation days = 2.0 |Apr precipitation days = 1.6 |May precipitation days = 3.1 |Jun precipitation days = 5.8 |Jul precipitation days = 7.5 |Aug precipitation days = 4.8 |Sep precipitation days = 2.5 |Oct precipitation days = 0.7 |Nov precipitation days = 0.7 |Dec precipitation days = 1.5 |Jan humidity = 44 |Feb humidity = 35 |Mar humidity = 30 |Apr humidity = 27 |May humidity = 30 |Jun humidity = 37 |Jul humidity = 40 |Aug humidity = 37 |Sep humidity = 34 |Oct humidity = 30 |Nov humidity = 35 |Dec humidity = 40 |Jan sun = 233.8 |Jan percentsun = 77 |Feb sun = 225.9 |Feb percentsun = 75 |Mar sun = 267.7 |Mar percentsun = 73 |Apr sun = 290.2 |Apr percentsun = 74 |May sun = 315.3 |May percentsun = 72 |Jun sun = 293.0 |Jun percentsun = 67 |Jul sun = 293.2 |Jul percentsun = 65 |Aug sun = 297.7 |Aug percentsun = 71 |Sep sun = 278.2 |Sep percentsun = 75 |Oct sun = 285.4 |Oct percentsun = 82 |Nov sun = 246.4 |Nov percentsun = 81 |Dec sun = 230.6 |Dec percentsun = 78 |source 1 = [https://web.archive.org/web/20130921055035/http://old-cdc.cma.gov.cn/shuju/search1.jsp?dsid=SURF_CLI_CHN_MUL_MMON_19712000_CES&tpcat=SURF&type=table&pageid=3 China Meteorological Administration] }} EconomyAs elsewhere in the Qaidam Basin, mining industries are of major importance in Da Qaidam. There is a lead mine in Xitieshan (锡铁山铅矿; {{coord|37|19|00|N|95|34|00|E|display=inline|region:CN-62_type:landmark}}), as well as a number of salt lakes where potash and related products are extracted.
