Xining

Xining (; ), alternatively known as Sining, is the capital of Qinghai province in western China and the largest city on the Tibetan Plateau.

The city was a commercial hub along the Northern Silk Road's Hexi Corridor for over 2000 years, and was a stronghold of the Han, Sui, Tang, and Song dynasties' resistance against nomadic attacks from the west. Although long a part of Gansu province, Xining was added to Qinghai in 1928. Xining holds sites of religious significance to Muslims and Buddhists, including the Dongguan Mosque and Ta'er Monastery. The city lies in the Huangshui River valley, and owing to its high altitude, has a cool climate on the borderline between cool semi-arid and dry winter humid continental. It is connected by rail to Lhasa, Tibet and connected by high-speed rail to Lanzhou, Gansu and Ürümqi, Xinjiang.

The city is home to Qinghai University, a comprehensive university and the only Project 211 university in Xining.

History

Xining has a history of over 2,100 years and was a chief commercial hub on the Hexi Corridor caravan route to Tibet, handling especially timber, wool and salt in ancient times. The trade along the Hexi Corridor was part of a larger trade corridor along the Northern Silk Road, whose use was intensified in the 1st century BC after efforts by the Han dynasty to control this route.

Under the Han dynasty (206 BC – 220 AD) a county called Linqiang was established to control the local Qiang tribesmen. It was again a frontier county under the Sui (581–618) and Tang (618–907) dynasties; during the 7th and early 8th centuries it was a center of constant warfare with Tuyuhun and Tibet. In 763, it was overrun by the Tibetans and while under Tibetan control was known to the Chinese as ''Qingtang cheng'' (). Recovered by the Song dynasty in 1104, it received the name Xining (meaning "peace in the west") and has been the seat of a prefecture or superior prefecture under that name since that time. In the late 16th century, the Kumbum Monastery was founded some to the southeast, establishing Xining as an important religious center for the Gelug School of Buddhists.

A major earthquake occurred May 22, 1927, measuring at a magnitude of 7.6. It was one of the deadliest earthquakes in China with a total count of over 40,000 deaths. It also caused large land fractures.

Xining was the extraterritorial capital of the Koko Nor territory and remained in Gansu until 1928, when it became the provincial capital of the newly established independent province of Qinghai.

Xining was subjected to aerial bombardment by Japanese warplanes in 1941 during the Second-Sino Japanese War. The bombing spurred all ethnicities in Qinghai, including the local Qinghai Mongols and Qinghai Tibetans, against the Japanese. The Salar Muslim General Han Youwen directed the defense of the city of Xining during air raids by Japanese planes.

Xining was given municipal status in 1945.

Under the rule of Governor Ma Bufang, Xining, like the rest of Qinghai, underwent industrialization and modernization. In 1947 the USA sold Ma Bufang a piped water (sewage) system which was installed in Xining. Ma Bufang also promoted education. He made businessmen methodically clean up Xining by serving as insect exterminators, killing flies and neatly throwing them away.

Since the late 1950s, when the Liujia Gorge Dam and hydroelectric project came into operation in neighboring Gansu province, Xining has been linked by a high-tension electrical grid to both Liujia and Lanzhou. It also uses local coal from mines at Datongxian to the north. A modern woollen mill was installed at Xining before 1957. The city also has a leather industry and is a market for salt from the Qaidam region. During the late 1950s medium-sized iron and steelworks were built there, supplying metal to Lanzhou.

Construction of a highway to the mineral-rich Qaidam basin, and completion in 1959 a link to the Chinese rail network via Lanzhou in Gansu province, has spurred industrial development. This effort was part of a plan of the central government to rapidly exploit oil and pasturage in the Xining area beginning in the 1950s.

Geography and climate

Xining is located in the eastern part of Qinghai Province and lies on the Huangshui River. It has a total area of .

Xining is located on the eastern edge of the Qinghai–Tibet Plateau and the upper reaches of the Huangshui River. It is the political, economic, and cultural center of Qinghai Province with an average altitude of about . Human activity in the region can be traced to 2,100 years ago. During the Western and Eastern Han dynasties, owing to its developing agriculture, Xining was paid noticed due to its economic and military significance. As well as being an important hinge between the Central Plains and the western part of China in ancient times, Xining was an important link in the Silk Road. It continues to be an important rail and road link to the hinterlands of the Qinghai–Tibet Plateau.

Xining has also been dubbed the Summer Resort Capital of China owing to its cool summer, with a borderline cold semi-arid climate ( Köppen ''BSk'')/dry winter humid continental climate (''Dwb''). Conditions are influenced by the aridity and high altitude. Nights are cold or cool throughout the year, and the diurnal temperature variation often reaches or exceeds . The monthly 24-hour average temperatures ranges from in January to in July; the annual mean is , still making it one of the warmest locations in Qinghai due to the low elevation by provincial standards. Rainfall falls mainly from May to September, and the area is often dry an
