Amur in the context of "Salmonids"

The Amur plate (or Amurian plate; also occasionally referred to as the China plate, not to be confused with the Yangtze plate) is a minor tectonic plate in the northern and eastern hemispheres.

The Amurian Plate is named after the Amur River, which forms the border between the Russian Far East and Northeast China.It is bounded on the north, west, and southwest by the Eurasian plate, on the east by the Okhotsk plate, to the southeast by the Philippine Sea plate along the Suruga Trough and the Nankai Trough, and the Okinawa plate, and the Yangtze plate.

Heilongjiang is a province in northeast China. It is the northernmost and easternmost province of the country and contains China's northernmost point (in Mohe City along the Amur) and easternmost point (at the confluence of the Amur and Ussuri rivers).

The province is bordered by Jilin to the south and Inner Mongolia to the west. It also shares a border with Russia (Amur Oblast, Jewish Autonomous Oblast, Khabarovsk Krai, Primorsky Krai and Zabaykalsky Krai) to the north and east. The capital and the largest city of the province is Harbin. Among Chinese provincial-level administrative divisions, Heilongjiang is the sixth-largest by total area, the 20th-most populous, and the second-poorest by GDP per capita after only Gansu province.

The Northeast China Plain (simplified Chinese: 东北平原; traditional Chinese: 東北平原; pinyin: Dōngběi Píngyuán), also known as Songliao Plain, Manchurian Plain, or Northeast Plain, is located in Northeast China. It lies between the Greater and Lesser Khingan and Changbai mountains, ending at the coast at Liaodong Bay in the Bohai Sea. Covering 350,000 km, it is China's largest plain, with an elevation of lower than 200 meters, and less than 100 meters to the southwest. The Songhua, Nen, and Liao Rivers run through the plain.

The Northeast Plain includes Songnen Plain in the north, Liaohe Plain in the south, and Sanjiang Plain in the northeast. The Songnen Plain was formed by the Songhua and alluvial soils from the Nen. The Liaohe Plain, located in the hilly areas near Changchun, was created by the separation of watersheds of the Songhua and Liao, which are collectively known as the Liaohe Plain. The Sanjiang Plain, at the confluence of the Songhua, Amur, and Ussuri Rivers, was originally a swamp known as the "Great Northern Wilderness", becoming a food-producing area after reclamation. The original wetland area of the Sanjiang Plain has been greatly reduced.

The Argun /ɑːrˈɡuːn/ or Ergune (Chinese: 额尔古纳河) 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 Ussuri (/uːˈsʊəri/ oo-SOOR-ee; Russian: Уссури [ʊsˈsurʲɪ]) or Wusuli (Chinese: 乌苏里; pinyin: wūsūlǐ [ǔsǔlî]) is a river that runs through Khabarovsk and Primorsky Krais, Russia and the southeast region of Northeast China in the province of Heilongjiang. It rises in the Sikhote-Alin mountain range, flowing north and forming part of the Sino-Russian border (which is based on the Sino-Russian Convention of Peking of 1860), until it joins the Amur as a tributary near Khabarovsk. It is approximately 897 km (557 mi) long. The Ussuri drains the Ussuri basin, which covers 193,000 km (75,000 sq mi). Its waters come from rain (60%), snow (30–35%), and subterranean springs. The average discharge is 1,620 m/s (57,000 cu ft/s), and the average elevation is 1,682 metres (5,518 ft).

Amur Oblast (/əˈmʊər ˈɒblæst/) is a federal subject of Russia (an oblast), located on the banks of the Amur and Zeya rivers in the Russian Far East. The oblast borders Heilongjiang province of the People's Republic of China (PRC) to the south.

The administrative center of the oblast, the city of Blagoveshchensk, is one of the oldest settlements in the far east of the country, founded in 1856. It is a traditional center of trade and gold mining. The territory is accessed by two railways: the Trans-Siberian Railway and the Baikal–Amur Mainline. As of the 2021 Census, the oblast's population was 766,912.
