Lanzhou

Lanzhou is the capital and largest city of Gansu province in northwestern China. Located on the banks of the Yellow River, it is a key regional transportation hub, connecting areas further west by rail to the eastern half of the country. Historically, it has been a major link on the Northern Silk Road and it stands to become a major hub on the New Eurasian Land Bridge. The city is also a center for heavy industry and petrochemical industry.
Lanzhou is the third largest city in Northwest China after Xi'an and Urumqi. Lanzhou is also an important center for scientific research and education in Northwestern China after Xi'an. The city is one of the top 60 major cities in the world by scientific research output as tracked by the Nature Index. It hosts several research institutions, including, Lanzhou University, Northwest Normal University, Lanzhou University of Technology, Gansu Agricultural University, Gansu University of Chinese Medicine, and Lanzhou Jiaotong University. Notably, Lanzhou University is one of China's prestige universities as a member of the Project 985.
Originally in the territory of the ancient Western Qiangs, Lanzhou became part of the territory of the State of Qin in the 6th century BC.
In 81 BC, under the Han dynasty (206 BC–AD 220), it was taken from the Huns' Huandi Chanyu and made the seat of Jincheng commandery (jùn), and later of the Jincheng (Golden City) county (xiàn), later renamed Yunwu. From at least the first millennium BC it was a major link on the ancient Northern Silk Road, and also an important historic Yellow River crossing site. To protect the city, the Great Wall of China was extended as far as Yumen. Parts of the Great Wall still exist within the built-up area.
After the fall of the Han dynasty, Lanzhou became the capital of a succession of tribal states. In the 4th century it was briefly the capital of the independent state of Liang. The Northern Wei dynasty (386–534) reestablished Jincheng commandery, renaming the county Jincheng. 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. 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 Tibetan Empire and in 843 was conquered by the Tang. Later it fell into the hands of the Western Xia dynasty (which flourished in Qinghai from the 11th to 13th century) and was subsequently absorbed by the Song dynasty (960–1126) in 1081. 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 Mongol Empire.
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 was made 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 Dungan revolt in 1864–1875. In the 1920s and 1930s it became a center of Soviet influence in northwestern China.
During the Second Sino-Japanese War (1937–1945) Lanzhou, linked with Xi'an by highway 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 to Ürümqi, Xinjiang.
Lanzhou's old Donggang Airport, located near the city centre, was the primary entry point for combat aircraft provided to China under the Sino-Soviet Non-Aggression Pact, and along with other targets around Lanzhou, including civilian centers, were heavily bombed by the Imperial Japanese Army Air Force and Navy Air Force. 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 30 BR.20 and Ki-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, 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 the Soviet 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 in Xi'an observed 21 of the original 30 IJAAF bombers returning from Lanzhou.
As the Imperial Japanese forces were preparing for Operation Z against the United States and other allies in Southeast Asia and the Pacific by mid-1941, the IJANF 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 an I-16 fighter aircraft, while avoiding confrontation against the Zero fighters, he shot down a Mitsubishi G3M bomber north of Lanzhou. On the ground, the KMT Muslim Generals Ma Hongkui and Ma Bufang protected Lanzhou with their cavalry troops, putting up such resistance that the Japanese never captured Lanzhou.
At 1,600 metres (5,200 ft) above sea level, Lanzhou lies in China's northwest geographical center. The metropolitan area covers more than 20 square kilometres (7.7 sq mi) of urbanisation along the southern banks of the Yellow River, which flows through from west to east. The Qilian Ranges, Mt. Pingliang, and Mt. Kongtong are located on the south and north sides of the city.
Lanzhou is situated on the upper reaches of the Yellow 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 the Hexi Corridor across Central Asia. It commands the approaches to the ancient capital area of Chang'an (modern Xi'an) in Shaanxi province from both the west and the northwest, as well as the area of Qinghai Lake via the upper waters of the Yellow River and its tributaries.
Lanzhou is situated in the temperate zone and has a semi-arid climate (Köppen BSk) with hot summers and cold and very dry winters. In the urban core, based on 1971–2000 normals, 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 annual rainfall is 309 millimetres (12.2 in), 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.
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 by Tsinghua University and The Asian Development Bank in January 2013, Lanzhou was among the ten most air-polluted cities in the world. Air quality reportedly was so poor that at times one could not see Lanshan, the mountain rising up along the south side of the city. 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. In 2011, using Chinese statistics, the World Health Organization reported that Lanzhou had the worst air quality among eleven western Chinese cities. Its annual mean PM10 μg/m of 150 is 7 times the safe level established by the World Health Organization. It was worse than Beijing with its reading of 121.
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." In 2015 it was awarded China's climate progress title. As a city once unable to be spotted from satellites, Lanzhou has taken various measures to combat air pollution in recent years, having reduced its Air Pollution Index at the fastest speed across China. According to the 2018 WHO database, 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). In recent years, several specimens of the endangered Chinese giant salamander have been found in and near the Yellow River in Lanzhou.
On April 11, 2014, Lanzhou officials advised residents not to drink tap water, because benzene levels were 20 times the national limit of 10 micrograms per liter. The city water supply suspected industrial chemical production to be the culprit, similar to what happened in the 2005 Jilin chemical plant explosions.
A brucellosis 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.
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. Lanzhou was also affected by 2008 Sichuan earthquake in 2008.
As of the 2020 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, retired migrant workers returning to Gansu, improved services in the city and government policies.
The 14,000-capacity Northwest Minzu University Stadium 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.
Lanzhou previously had a professional soccer team named Gansu Tianma from 1999 to 2003.The team played in Chinese Football Association Yi League from 1999 to 2001 and bought a position in the Jia League from Tianjin Lifei. The team relocated to Ningbo, Zhejiang and changed their name to Ningbo Yaoma in 2003. The team later relegated to China League Two in 2004 and became Dongguan Dongcheng after moving to Dongguan, Guangdong.
Former England international Paul Gascoigne played four games in both a playing and coaching role for Gansu in 2003, scoring two goals, before returning to England after falling out with the club, as his mental state meant that he had to return to America for treatment against drink and depression.
On August 20, 2012, Lanzhou New Area was approved by the State Council of China's Central Government. In 2019, Lanzhou New Area was formally established as a county-level division of Lanzhou, its area being split off from Yongdeng and Gaolan. The updated area and population of Yongdeng and Gaolan are not yet reflected in the table.
Since 1949 Lanzhou has been transformed from the capital of a poverty-stricken province into the center of a major industrial area. It was one of the first cities in China to industrialize, as a focus of the First and Second Five-Year Plans.
The GDP per capita of Lanzhou was 25,566 (RMB) (US$3,681) in 2008, ranking it at number 134 among 659 Chinese cities. In 2015, the GDP per capita had grown to 57,191 RMB (US$9,182.28) and the city ranked at place 100 for total GDP of Chinese cities.

Lanzhou Metro Line 2 (First-stage project), opened in June 2023. Passengers can transfer between Line 1 and Line 2 at Dongfanghong Square Station and Wulipu Station.
Lanzhou Railway Station is a major railway hub of western China. Every day over 100 passenger trains originate or pass via this station. It is a vital focal point connecting the western provinces with the east. Lanzhou Railway Station is located on Huochezhan Dong Lu, in Chengguan district. Lanzhou West Railway Station is the city's second major railway station, offering connection to high-speed rail services.
Lanzhou Railway Station has the following railway connections:
New high-speed passenger-only railways are completed both toward the east (the Xuzhou–Lanzhou high-speed railway), the west (the Lanzhou–Xinjiang high-speed railway) and the north (the Yinchuan–Lanzhou high-speed railway). These services only stop at Lanzhou West Railway Station. The Sichuan–Qinghai railway, which is designed for a top speed of 200 km/h (120 mph) to 250 km/h (160 mph), is under construction.
Lanzhou forms an important link in one of the routes of the Eurasian Land Bridge and also provides rail access to Qinghai, Xinjiang and Tibet further to the west. A large rail freight terminal has recently been constructed to accommodate increasing volumes of rail freight and Lanzhou is home to China's fourth largest marshalling yard.
Regular freight services connect Lanzhou to destinations including Chongqing, Hamburg, Almaty and Kathmandu.
In 2016, Lanzhou was ranked 4th of Chinese cities with the worst rush hour traffic jams; however, by 2017, after completion of an urban ring road, it dropped to 33rd place.
For long-distance buses, there are three major bus stations in the urban area, West Bus Station in Xiaoxihu neighbourhood, East Bus Station near Lanzhou Station and South Bus Station near G75 Lanzhou–Haikou Expressway terminus. Furthermore, there are a total of 132 local city bus lines. These have their main node station at Xiguan.
