Lanzhou and theZhongshan Bridge under construction in 1909 taken byRobert Sterling ClarkThe West Gate (西关;Xīguān) of the old city wall in 1875. It has been demolished, although its busy neighborhood still bears its name.
Originally in the territory of theancient Western Qiangs, Lanzhou became part of the territory of theState of Qin in the 6th century BC.
In 81 BC, under theHan dynasty (206 BC–AD 220), it was taken from the Huns' Huandi Chanyu and made the seat ofJinchengcommandery (jùn), and later of the Jincheng (Golden City)county (xiàn), later renamedYunwu. From at least the first millennium BC it was a major link on the ancientNorthern Silk Road,[12][13] and also an important historicYellow River crossing site. To protect the city, theGreat Wall of China was extended as far asYumen. Parts of the Great Wall still exist within the built-up area.[14]
After the fall of theHan dynasty, Lanzhou became the capital of a succession of tribal states. In the 4th century it was briefly the capital of the independent state ofLiang. TheNorthern Wei dynasty (386–534) reestablishedJincheng commandery, renaming the countyJincheng. Mixed with different cultural heritages, the area at present-dayGansu province, from the 5th to the 11th century, became a center forBuddhist study. Under theSui dynasty (581–618) the city became the seat of Lanzhou prefecture for the first time, retaining this name under theTang dynasty (618–907). In 763 the area was overrun by theTibetan Empire and in 843 was conquered by theTang. Later it fell into the hands of theWestern Xia dynasty (which flourished inQinghai from the 11th to 13th century) and was subsequently absorbed by theSong dynasty (960–1126) in 1081. The name Lanzhou was reestablished, and the county renamed Lanzhuan.
After 1127 it fell into the hands of theJin dynasty, and after 1235 it came into the possession of theMongol Empire.
Under theMing dynasty (1368–1644) the prefecture was demoted to a county and placed under the administration ofLintao superior prefecture, but in 1477 Lanzhou was reestablished as a political unit.
The city acquired its current name in 1656, during theQing dynasty. WhenGansu was made a separate province in 1666, Lanzhou became its capital.
In 1739 the seat ofLintao was transferred to Lanzhou, which was later made a superior prefecture called Lanzhou.
During theSecond Sino-Japanese War (1937–1945) Lanzhou, linked withXi'an byhighway in 1935, became the terminus of the 3,200 km (2,000 mi) 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 toÜrümqi,Xinjiang.
Lanzhou's oldDonggang Airport, located near the city centre, was the primary entry point for combat aircraft provided to China under theSino-Soviet Non-Aggression Pact, and along with other targets around Lanzhou, including civilian centers, were heavily bombed by theImperial Japanese Army Air Force andNavy Air Force.[15] Many air battles were fought between the Chinese Air Force and the Imperial Japanese air forces over Lanzhou and surrounding regions from 1937 to 1945, particularly from 1938 to 1941 when the influx of Soviet war materials formed the primary support in China's War of Resistance against the Imperial Japanese invasion. Instances of major air-battles include an IJAAF raid consisting of 30BR.20 andKi-21 bombers against civilian targets in Lanzhou on 20 February 1939;17th PS, 5th PG commander Capt.Cen Zeliu and his deputy commander Capt. Ma Guolian (Ma Kwok-Lim), a Canadian-Chinese volunteer for the Chinese Air Force,[16] shot down the first two bombers in the battle, followed by two more downed as Capt. Cen led another attack on the third formation. They would be joined by pilots of theSoviet Volunteer Group led by Nikolay Garilov and the 15th PS led by Li Debiao, who would all shoot down five more of the Japanese bombers; the northern Chinese air-raid early-warning net headquarters inXi'an observed 21 of the original 30 IJAAF bombers returning from Lanzhou.
As the Imperial Japanese forces were preparing forOperation Z against the United States and other allies in Southeast Asia and the Pacific by mid-1941, theIJANF were busy training new aircrews in live combat action across China for the upcoming war in the Pacific; on 22 May 1941, Lt.Gao Youxin of the 21st PS, 4th PG engaged an IJNAF raid on Lanzhou in anI-16 fighter aircraft, while avoiding confrontation against theZero fighters, he shot down aMitsubishi G3M bomber north of Lanzhou. On the ground, theKMTMuslim GeneralsMa Hongkui andMa Bufang protected Lanzhou with their cavalry troops, putting up such resistance that the Japanese never captured Lanzhou.[17]
At 1,600 metres (5,200 ft) above sea level, Lanzhou lies inChina's northwest geographical center. The metropolitan area covers more than 20 square kilometres (7.7 sq mi) of urbanisation along the southern banks of theYellow River, which flows through from west to east. TheQilian Ranges,Mt. Pingliang, andMt. Kongtong are located on the south and north sides of the city.
Lanzhou is situated on the upper reaches of theYellow River where it emerges from the mountains and has been a center since early times, being at the southern end of the route leading via theHexi Corridor acrossCentral Asia. It commands the approaches to the ancient capital area ofChang'an (modernXi'an) inShaanxi province from both the west and the northwest, as well as the area ofQinghai Lake via the upper waters of the Yellow River and its tributaries.

Lanzhou is situated in thetemperate zone and has asemi-arid climate (KöppenBSk) with hot summers and cold and very dry winters. In the urban core, based on 1971–2000 normals,[18] the monthly 24-hour average temperature ranges from −4.1 °C (24.6 °F) in January to 23.4 °C (74.1 °F) in July. The mean annual temperature is 10.9 °C (51.6 °F), while annualrainfall is 309 millimetres (12.2 in),[18] almost all of which falls from May to October. The winters are so dry that snowfall is sometimes restricted to fall and spring. With monthly percent possible sunshine ranging from 47 percent in September to 57 percent in April, sunshine is generous but not abundant, as the city receives 2,350 hours of bright sunshine annually.[19]

The city is located in a narrow and curved river valley with surrounding mountains causing it to be hemmed in blocking a free flow of air. According to the National Environmental Analysis released byTsinghua University and The Asian Development Bank in January 2013, Lanzhou was among the ten most air-polluted cities in the world.[22] Air quality reportedly was so poor that at times one could not seeLanshan, the mountain rising up along the south side of the city.[23] Lanzhou is also the home of many factories, including some involved in petroleum processing, and suffers from largedust storms kicked up from theGobi Desert, especially in the winter and spring. In 2011, using Chinese statistics, theWorld Health Organization reported that Lanzhou had the worst air quality among eleven western Chinese cities. Its annual meanPM10 μg/m3 of 150 is 7 times the safe level established by theWorld Health Organization. It was worse than Beijing with its reading of 121.[24]
Since then, authorities have taken measures to improve air quality, which have largely been successful. "Thirteen polluting enterprises with excessive capacity have been closed, more than 200 highly polluting enterprises were suspended in winter, and 78 industrial enterprises have moved to an industrial park outside the city."[23] In 2015 it was awarded China's climate progresstitle. As a city once unable to be spotted from satellites, Lanzhou has taken various measures to combatair pollution in recent years, having reduced its Air Pollution Index at the fastest speed across China.[25] According to the 2018 WHO database,[26] of 2700 towns listed, Lanzhou has the 158th highest level of PM 2.5 pollution, with an average of 54 micrograms per cubic meter (twice that of Milan). The large particle PM10 remains high, at 132 micrograms per cubic meter, in part as a result of sand storms.
The reach of the Yellow River at Lanzhou carries a high load of silt, giving the river its characteristic muddy appearance; however water quality in this reach is better than the "fetid outflow that barely passes for water two hours downstream" (2008).[27] In recent years, several specimens of the endangeredChinese giant salamander have been found in and near the Yellow River in Lanzhou.[28][29]
On April 11, 2014, Lanzhou officials advised residents not to drink tap water, becausebenzene levels were 20 times the national limit of 10 micrograms per liter.[30] The city water supply suspected industrial chemical production to be the culprit, similar to what happened in the2005 Jilin chemical plant explosions.[31]
Abrucellosis outbreak infecting humans took place in Lanzhou in 2020 after the Lanzhou Biopharmaceutical Plant involved in vaccine production accidentally pumped out the bacteria into the atmosphere in exhaust air, due to use of expired desinfectant, and affecting over 3,000 people.[32][33]
Lanzhou experiences earthquakes regularly, although usually at low intensities. In 1920 a large earthquake was experienced killing more than 100,000 people in Ningxia and Eastern Gansu province, although only 42 were killed in Lanzhou itself, the low number being attributed to the strong yet flexible nature of the wooden buildings in the city.[34] Lanzhou was also affected by2008 Sichuan earthquake in 2008.
As of the2020 Chinese census, Lanzhou surpassed 4 million population for the first time, with a total population of 4,359,446 inhabitants and 3,042,863 in the built-up (or metro) area of 1,112.9 square kilometres (429.7 sq mi) made of the 4 central urban districts (Chengguan, Qilihe, Anning and Xigu District).Lanzhou New Area, near the airport and Honggu Districts are not yet conurbated. The growth increased significantly after a period of slower growth. The strong growth has been attributed to parents seeking better education opportunities for their children, retiredmigrant workers returning to Gansu, improved services in the city and government policies.[35]
The 14,000-capacityNorthwest Minzu University Stadium[36] is one of the main sports venues in the city. It is mostly used for football games. A new sports center complex, including a stadium with a capacity of 60,000 spectators and a swimming hall, is under development.[37]
FormerEngland internationalPaul Gascoigne played four games in both a playing and coaching role for Gansu in 2003,[39][40] scoring two goals,[41][42] before returning toEngland after falling out with the club,[43][44] as his mental state meant that he had to return to America for treatment against drink and depression.[45]
A On August 20, 2012, Lanzhou New Area was approved by the State Council of China's Central Government.[47] In 2019, Lanzhou New Area was formally established as acounty-level division of Lanzhou, its area being split off from Yongdeng and Gaolan.[48][49] The updated area and population of Yongdeng and Gaolan are not yet reflected in the table.
