Qilian Shan

The Qilian Mountains (, also romanized as Tsilien; Mongghul: Chileb), together with the Altyn-Tagh (Altun Shan) also known as Nan Shan (, literally "Southern Mountains"), as it is to the south of Hexi Corridor, is a northern outlier of the Kunlun Mountains, forming the border between Qinghai and the Gansu provinces of northern China.

Geography

The range stretches from the south of Dunhuang some 800 km to the southeast, forming the northeastern escarpment of the Tibetan Plateau and the southwestern border of the Hexi Corridor.

The eponymous Qilian Shan peak, situated some 60 km south of Jiuquan, at , rises to 5,547 m. It is the highest peak of the main range, but there are two higher peaks further south, Kangze'gyai at wit
5,808 m
and
Qaidam Shan peak at wit
5,759 m
Other major peaks include Gangshiqia Peak in the east.

The Nan-Shan range continues to the west as Yema Shan (5,250 m) and Altun Shan (Altyn Tagh) (5,798 m). To the east, it passes north of Qinghai Lake, terminating as Daban Shan and Xinglong Shan near Lanzhou, with Maoma Shan peak (4,070 m) an eastern outlier. Sections of the Ming Dynasty's Great Wall pass along its northern slopes, and south of northern outlier Longshou Shan (3,616 m).

The Qilian mountains are the source of numerous, mostly small, rivers and creeks that flow northeast, enabling irrigated agriculture in the Hexi Corridor (Gansu Corridor) communities, and eventually disappearing in the Alashan Desert. The best known of these streams is the Ejin (Heihe) River. The region has many glaciers, the largest of which is the Touming Mengke. These glaciers have undergone acceleration in their melting in recent decades.

The characteristic ecosystem of the Qilian Mountains has been described by the World Wildlife Fund as the Qilian Mountains conifer forests.

Biandukou (), with an altitude of over 3500 m, is a pass in the Qilian Mountains. It links Minle County of Gansu in the north and Qilian County of Qinghai in the south.

History

The ''Shiji'' mentions the name "Qilian mountains" together with Dunhuang in relation to the homeland of the Yuezhi. These ''Qilian Mountains'' however, has been suggested to be the mountains now known as Tian Shan, 1,500 km to the west. ''Dunhuang'' has also been argued to be the Dunhong mountain. ''Qilian'' () is said to be a Xiongnu word meaning "sky" () according to Yan Shigu, a Tang Dynasty commentator on the ''Hanshu''. Sanping Chen (1998) suggested that 天 ''tiān'', 昊天 ''hàotiān'', 祁連 ''qílián'', and 赫連 '' Hèlián'' were all cognates and descended from multisyllabic Proto-Sinitic *''gh?klien''. Schessler (2014) objects to Yan Shigu's statement that 祁連 was a Xiongnu word; he reconstructs 祁連's pronunciation in around 121 BCE as *''gɨ-lian'', apparently the same etymon as 乾 (☰) the Trigram for "Heaven", in standard Chinese ''qián'' < Middle Chinese QYS *''gjän'' < Eastern Han Chinese ''gɨan'' < Old Chinese *''gran'', which Schuessler etymologizes as from Proto-Sino-Tibetan and related to Proto-Tibeto-Burman *''m-ka-n'', cognate with Written Tibetan མཁའ (Wylie transliteration: mkha') “heaven”.

The Tuyuhun were based around the Qilian mountains.

The mountain range was formerly known in European languages as Richthofen Range after Ferdinand von Richthofen, who was the Red Baron's explorer-geologist uncle.Winchester, Simon. (2008).
