19-648: Yakeshi has a population of 391,627 and an area of 27,590 square kilometres (10,650 sq mi). It is situated next to the Hailar River 70 kilometres (43 mi) east of Hailar District , the seat of Hulunbuir, and on the north side of the Greater Khingan Range. The city's economy is based on forestry industry , wood products, traditional Chinese medicines , gold , coal , iron , copper , wheat , rapeseed farming, sheep raising and dairy industries. In 2008 several major players in

38-531: A half from 2000 to 2008 when compared with prior decades. In years with high precipitation, the normally exitless Hulun Lake may overflow at its northern shore, and the water will meet the Ergune River after about 30 kilometres or 19 miles. The Ergune marks the border between Russia and China for about 944 kilometres or 587 miles, until it meets the Amur River . The system Kherlen-Ergune-Amur has

57-631: A total length of 5,052 kilometres or 3,139 miles. Near the city of Choibalsan in the Dornod province (far Northeast Mongolia), the Kherlen river feeds several soda lakes , located (geologically) in the north Kerulen Block of the Central Mongolian Fold System. They are closed lakes fed by groundwater, with hardly any surface inflow or outflow, in basins formed in basalt , pyroclastic material and rhyolite erupted from

76-780: Is a 1,254 km river in Mongolia and China . It is also one of the two longest rivers in Mongolia, along with the Orkhon River . The river originates in the south slopes of the Khentii mountains , near the Burkhan Khaldun mountain in the Khan Khentii Strictly Protected Area , about 180 kilometres or 112 miles northeast of Ulaanbaatar . This area constitutes the divide between

95-869: Is a 1,620-kilometre (1,010 mi) long river that forms part of the eastern China–Russia border , together with the Amur . Its upper reaches are known as the Hailar River ( 海拉尔河 ) in China . The Argun marks the border (established by the Treaty of Nerchinsk in 1689) between Russia and China for about 944 kilometres (587 mi), until it meets the Amur. The name derives from Buryat Urgengol 'wide river' ( urgen 'wide' + gol 'river'). Mongolian word "ergün" (in Traditional Mongolian alphabet ) or "örgön" (in modern Mongolian) means "wide". The river flows from

114-537: Is a legend related to the Ergüne hun Mongol ancestry. In this legend, the Mongols prevailed over other tribes and carried such slaughter among them, that in living remained no more than two men and two women. These two families, in fear of the enemy, fled to the inhospitable terrain, which included only mountains and forests and to which there was no road. Among those mountains was the abundant grass and healthy climate of

133-423: Is a potential source of uranium in the region's groundwater and soda lakes. Contamination may also result from large dust storms, which are frequent during the spring when the soda lakes are driest. It has been noted that Shar Burdiin lake shows the maximum concentration in uranium (with, only a short distance away, Gurvany-2 lake not far behind in uranium concentration); and that said concentration decreases while

152-830: Is in Suzhou in Eastern China. The city is connected by rail to Harbin and Hailar , and the nearest airport is in Hailar. The original name for the city, Xuguit Banner, came from the Mongolian word for the area. Its name was changed to Yakeshi in 1983 when it was designated a county-level city. Yakeshi is made up of 6 subdistricts and 10 towns . Others: Yakeshi is located on the Harbin-Manzhouli Railway . Hailar River The Argun / ɑːr ˈ ɡ uː n / or Ergune ( Chinese : 额尔古纳河 )

171-677: The Choibalsan – Onon volcanic chain during the late Cretaceous ; among these lakes are the Tsaidam lakes, the Gurvany lakes and the Shar Burdiin lake. The groundwater that feeds the soda lakes comes from a shallow unconfined aquifer recharged by rainfall and snowmelt, and from precipitation in the highlands north of the lakes. But the local climate is semi-arid, with only 207 mm mean annual precipitation distributed unequally throughout

190-855: The Jin dynasty (1115–1234) in northern China. The Manchu people who founded the Qing dynasty (1644–1912) additionally claimed descent from the Jurchens. Following the Russian conquest of Siberia in the 17th century, Russia-China relations were formalized in the 1689 Treaty of Nerchinsk , which established the Argun River as the China–Russia border . However, prior to the Amur Annexation of Outer Manchuria , China's border extended further to include

209-553: The Urov , Uryumkan and Gazimur from the left, and the Gen He from the right. In years with high precipitation, the normally exitless Hulun Lake may overflow at its northern shore, and the water will meet the Argun after about 30 kilometres (19 mi). The Kherlen – Argun – Amur system has a total length of 5,052 kilometres (3,139 mi). In The Secret History of the Mongols

228-613: The Arctic ( Tuul River ) and Pacific (Kherlen, Onon ) basins and is consequently named "Three River Basins". From there the Kherlen flows in a mostly eastern direction through the Khentii aimag . Further downriver, it crosses the eastern Mongolian steppe past Ulaan Ereg and Choibalsan , entering China at 48°3′N 115°36′E  /  48.050°N 115.600°E  / 48.050; 115.600 and emptying into Hulun Nuur after another 164 kilometres or 102 miles. The mean streamflow of Kherlen River has decreased by more than

247-512: The Shar Burdiin lake, uranium concentration has been measured at 62.5 μM, which may be the highest reported naturally occurring U concentration in a surface water body. Shar Burdiin is also the most highly evaporated lake. No uranium deposits have been identified within their catchment area. However, approximately 100 km north of the lakes, there are several deposits of uraninite (pitchblende) / coffinite assemblages within conglomerates and sandstones . Devitrification of volcanic glass

266-783: The Western slope of the Greater Xing'an Range in China's Inner Mongolia , and forms the Chinese side of the two rivers that flow together to produce the Amur (Heilong). Its confluence with the Shilka at Ust-Strelka on the Russian side forms the Amur. The Argun is 1,620 kilometres (1,010 mi) long including its upper course Hailar, and has a drainage basin of 164,000 square kilometres (63,000 sq mi). Its main tributaries are

285-574: The automobile industry established car testing facilities in Yakeshi. As part of the Electronic stability control (ESC)-development for new cars, special prototype cars are tested under winter conditions on frozen lakes and special snow-tracks. The first such test facilities were set up in the city by the German automobile supplier Robert Bosch GmbH whose development center for the Chinese car market

304-506: The distance from that area increases, as seen from Tsaidam-2 lake and Gurvany-1 lake which are over 15 km from Shar Burdiin Lake. So another possibility for the contamination is that of wind-blown salts from Shar Burdiin lake and Gurvany-2 lake, reaching the lakes and groundwaters in other parts of the area. The Khuduu Aral, a 30 kilometre long and 20 km wide plain on the Kherlen river, is home to Genghis Khan's Ikh Aurag (palace). Nearby it there

323-555: The so-called Sixty-Four Villages East of the River in present-day Amur Oblast , southern Khabarovsk , and all of Primorsky Krai . Although the subsequent Amur Annexation fixed the eastern Sino-Russian border at the Amur, it would only be at the 1991 Sino-Soviet Border Agreement when all Sino-Soviet border conflicts would be resolved. Kherlen River Kherlen River (also known as Kern or Kerülen ; Mongolian : Хэрлэн гол ; Chinese : 克鲁伦河 ; pinyin : Kèlǔlún hé )

342-612: The steppe. Then, legend tells that in Ergune-Khun, Mongols multiplied and become masters of iron smelting and blacksmithing. According to legend, it is the art of melting iron that has helped them escape from the mountain gorges on scope of the current Mongolian steppes, to the Kherlen (Kelulun) and Onon River . Prior to the emergence of the Mongols, the Amur River basin was home to certain tribes of Jurchen people , who founded

361-507: The year. This means that groundwater recharge is relatively rare: only the largest precipitation events and snowmelt periods result in significant recharge. The Kherlen River is the regional discharge point and also represents a hydrogeological divide for the shallow unconfined aquifer, as groundwater flows south along the topographic gradient. The lakes in their shallow closed basins act as evaporative discharge points. Several of these lakes are exceedingly rich in uranium; in one location of
