Mount Liupan (Chinese: 六盘山; pinyin: Lìupán Shān) is a mountain rangeinnorthwestern China, located mostly in southern Ningxia Hui Autonomous Region. It marks the southwestern boundary of the Ordos Basin.
Its southern section is known as Mount Long (Chinese: 陇山; pinyin: Lǒng Shān), which strides southeast through eastern Gansu and western Shaanxi province before joining into the Qinling Mountains, giving rise to regional names like "Longxi" (陇西, lit. "west of Mount Long"), "Longdong" (陇东, "east of Mount Long", referring to the Jing River valley basin region around eastern Pingliang, southern Qingyang and northern Xianyang) and "Longnan" (陇南, "south of Mount Long"). It is the western boundary of the Guanzhong Plain, and is also the source of the Qian River (千河), a left tributary of the Wei River that flows through the prefectural cityofBaoji.
A poem of same name was dedicated to this mountain by Mao Zedong in 1935, when the Chinese Red Army arrived into the friendly Shaanbei region at the end of the Long March.[2]
- 《清平乐·六盘山》
- 天高云淡，望断南飞雁。
- 不到长城非好汉，屈指行程二万。
- 六盘山上高峰，红旗漫卷西风。
- 今日长缨在手，何时缚住苍龙？
- Mount Liupan
- The sky is high, the clouds are pale,
- We watch the wild geese flying south until they vanish.
- If we reach not the Great Wall we are no true men,
- Already we have come twenty thousand li.
- High on the crest of Mount Liupan,
- Banners idly wave in the west wind.
- Today the long cord is in our hands,
- When shall we bind fast the Gray Dragon?
It is one of the youngest mountain ranges of China.[3] It is relatively narrow with a width between 5 and 12 km, and a length of around 240 km.[1] The highest peak, Migangshan (米缸山), is at 2,942 m (9,652 ft) above sea level.[3] Owing to its orientation perpendicular to humid winds, it is considered a 'green island' within the Loess Plateau.[4] Most of the mountain's area is covered by forests.[3]
