Information of Lanzhou
Lanzhou (Simplified Chinese: 兰州; Traditional Chinese: 蘭州; pinyin: Lánzhôu; Wade-Giles: Lan-chou; Postal map spelling: Lanchow) is a prefecture-level city and capital of Gansu province in northwestern China.
History
Originally in the territory of the Western Qiang peoples, Lanzhou became part of the territory of Qin in the 6th century BC.
In 81 BC, under the Han dynasty (206 BC–220 AD), it became the seat of Jincheng county (xian) and later of Jincheng commandery (jun), the county being renamed Yunwu. The city used to be called the Golden City, when it was a major stop on the ancient Silk Road. To protect the city, the Great Wall of China was extended as far as Yumen.
After the fall of the Han Dynasty, Lanzhou became the capital of a succession of tribal states. Mixed with different cultural heritages, the area at present-day Gansu province, from the 5th to the 11th century, became a center for Buddhist study. In the 4th century it was briefly the capital of the independent state of Earlier Liang. The Northern Wei dynasty (386–534) reestablished Jincheng commandery, renaming the county Zicheng. Under the Sui Dynasty (581–618) the city became the seat of Lanzhou prefecture for the first time, retaining this name under the Tang Dynasty (618–907). In 763 the area was overrun by the Tibetans and was then recovered by the Tang in 843. Later it fell into the hands of the Western Xia Dynasty (which flourished in Qinghai from the 11th to 13th century) and was subsequently recovered by the Song Dynasty (960–1126) in 1041. The name Lanzhou was reestablished, and the county renamed Lanzhuan.
After 1127 it fell into the hands of the Jin Dynasty, and after 1235 it came into the possession of the Mongols. Under the Ming Dynasty (1368–1644) the prefecture was demoted to a county and placed under the administration of Lintao superior prefecture, but in 1477 Lanzhou was reestablished as a political unit.
The city acquired its current name in 1656, during the Qing Dynasty. When Gansu became a separate province in 1666, Lanzhou became its capital.
In 1739 the seat of Lintao was transferred to Lanzhou, which was later made a superior prefecture called Lanzhou.
Lanzhou was badly damaged during the rising of the Gansu Muslims in 1864–1875. In the 1920s and 1930s it became a center of Soviet influence in northwestern China. During the Sino-Japanese War (1937–1945) Lanzhou, linked with Xi'an by highway in 1935, became the terminus of the 3,200 km (2,000 mile) Chinese-Soviet highway, used as a route for Soviet supplies destined for the Xi’an area. This highway remained the primary traffic route of northwestern China until the completion of the railway from Lanzhou to Urumqi, Xinjiang. During the war Lanzhou was heavily bombed by the Japanese.
The city is the seat of a currently vacant Roman Catholic diocese[1] and was previously the center of a vicariate apostolic (Vicariate Apostolic of Northern Kan-Su).

Climate and environment

Lanzhou is said to be one of the most polluted cities in China. According to the Blacksmith Institute, Lanzhou is one of the 30 most polluted cities in the world. The air quality is so poor that at times one can not see Lanshan, the mountain rising straight up along the south side of the city. The city is located in a narrow river valley with an unfortunate curve causing it to be hemmed in with no free air flow. Lanzhou is also the home of many factories, including some involved in petroleum processing, and suffers from large dust storms kicked up from the Gobi Desert, especially in the winter and spring.
Productivity
Since 1949 Lanzhou has been transformed from the capital of a poverty-stricken province into the center of a major industrial area. The GDP per capita of Lanzhou was 15,051 yuan (RMB) (ca. US$1,820) in 2003, ranked no. 134 among 659 Chinese cities.
