West Dabusun or Dabuxun Lake is an ephemeral lake northwest of Golmud in the Haixi Prefecture of Qinghai Province in northwestern China. Comprising a basin in the Qarhan Playa, it fills when meltwater floods the Golmud River, causing it to spill into subsidiary channels west of the main course to Dabusun Lake. Like the other lakes of the surrounding Qaidam Basin, it is extremely saline.

Name

[edit]

Dabusun[1][2][3] or Dabsan[4] is a romanization of a Mongolian name meaning "Salt Lake".[5] The adjective "west" distinguishes it from nearby Dabusun Lake.[5] Dabuxun[6] is the pinyin romanization of the Mandarin pronunciation of the same name's transcription into characters. Xi Dabsan[4] or Xidabuxun[7] are the same names, prefixed with the Chinese word for "West".

Geography

[edit]

West Dabusun Lake lies in the Dabusun subbasin[8] in the central Qarhan Playa in the southeastern corner of the Qaidam Basin[6] at an elevation of 2,675 m (8,776 ft).[4] Although sometimes listed as perennial, it is an ephemeral saline lake fed by the "Yuejin River" (t 躍進, s 跃进, Yuèjìn Hé),[9] a subsidiary western channel of the Golmud that periodically fill with meltwater.[10] It usually reaches a size of about 30 km2 (12 sq mi).[4] In Qaidam's hyperarid climate, there is generally only 28–40 mm (1–2 in) of annual rainfall but about 3,000 mm (120 in) of annual evaporation;[7] the accumulated pool evaporates before the end of the year. It is never more than about 1 m (3 ft 3 in) deep.[7]

The lake's position towards the southern end of the playa means that its waters are relatively less influenced by the concentrated mineral springs along the playa's northern boundary.[11]

History

[edit]

West Dabusun Lake formed in 1967.[2]
