Heilongjiang

Heilongjiang () formerly romanized as Heilungkiang, is a province in northeast China. The standard one-character abbreviation for the province is (). It was formerly romanized as "Heilungkiang". 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 junction 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 15th-most populous, and the second-poorest by GDP per capita.

The province takes its name from the Amur River (see the etymology section below for details) which marks the border between the People's Republic of China and Russia.

Heilongjiang has significant agricultural production, and raw materials, such as timber, oil and coal.

Etymology

The province takes its name from the Amur River, whose Mandarin name is ''Heilongjiang'' which is a literal and same-word-order translation of "black dragon river". ''Hei'' comes from qara/hara/har, a common Altaic language cognate meaning "black". ''Long'' comes from the Mandarin word for "dragon". ''Jiang'' means "river" in Mandarin.

History

Ancient Chinese records and other sources state that Heilongjiang was inhabited by people such as the Sushen, Buyeo, the Mohe, and the Khitan. Mongolic Donghu people lived in Inner Mongolia and the western part of Heilongjiang. Some names are Manchu or Mongolian. The eastern portion of Heilongjiang was ruled by the Bohai Kingdom between the 7th and 10th centuries, followed by the Khitan Liao dynasty. The Jurchen Jin dynasty (1115–1234) that subsequently ruled much of north China arose within the borders of modern Heilongjiang.

Heilongjiang as an administrative entity was created in 1683, during the Kangxi era of the Manchu Qing Dynasty, from the northwestern part of the Jilin province. This Heilongjiang Province only included the western part of today's Heilongjiang Province, and was under the supervision of the General of Heilongjiang (Sahaliyan Ula i Jiyanggiyūn) (the title is also translated as the Military Governor of Heilongjiang; ''jiyanggiyūn'' is the Manchu reading of the Chinese word ; "military leader, general" and is cognate with Japanese ''shōgun''), whose power extended, according to the Treaty of Nerchinsk, as far north as the Stanovoy Mountains. The eastern part of what's today Heilongjiang remained under the supervision of the General of Jilin (Girin i Jiyanggiyūn), whose power reached the Sea of Japan. These areas deep in Manchuria were closed off to Han Chinese migration.

The original seat of the Military Governor of Heilongjiang, as established in 1683, was in Heilongjiang City (also known as Aigun or Heihe, or, in Manchu, Saghalien Ula), located on the Amur River. However, already in 1690 the seat of the governor was transferred to Nenjiang (Mergen) on the Nen River, and, in 1699, further south to Qiqihar. According to modern historians, the moves may have been driven by supply considerations: Nenjiang and Qiqihar are connected by a convenient waterway (Nen River) with southern Manchuria, whereas accessing Aigun (Heihe) would require either sailing all the way down the Sungari River until its confluence with the Amur and then up the Amur to Heihe, or using a portage over the Lesser Xing'an Mountains between the Nen River valley and the Amur valley. An additional advantage of Qiqihar may have been its location at the junction of a northbound road (to Nenjiang) and a westbound one (to Mongolia), enabling its garrison to defend both against the Russians and the Ölöt Mongols.

Little Qing Military presence existed north of Aigun. According to the 18th- and early-20th-century European sources and the reports of the Russians in the 1850s, the farthest Qing "advance guard" post was at Ulusu-Modon (Ulussu-Mudan) ( ''Wūlǔsūmùdān''), near the Amur River's famous S-shaped meander. (The post was on the left (north) bank of the river, lost to the Russians in 1860.)

In 1858 and 1860, the Qing government was forced to give up all land beyond the Amur and Ussuri Rivers to the Russian Empire, cutting off the Qing Empire from the Sea of Japan and giving Heilongjiang its present northern and eastern borders. At the same time, Manchuria was opened to Han Chinese migration by the Qing government. By the early twentieth century, due to the ''Chuang Guandong'', the Han Chinese had become the dominant ethnic group in the region.

In 1931, Japanese forces invaded Heilongjiang. In 1932, the Japanese completed their conquest of the province, which became part of the Japanese puppet state of Manchukuo.

In 1945, Japanese forces in Manchuria were defeated by the Soviet Army. During the Chinese Civil War, Soviet forces aided the Chinese communists. Heilongjiang became the first province to be completely controlled by the communists and Harbin the first major city to be controlled by them.

At the beginning of communist rule, Heilongjiang included only the western portion of the present-day province, and had its capital at Qiqihar. The remaining area was the province of Songjiang; its capital was Harbin. In 1954, these two provinces were merged into present-day Heilongjiang. During the Cultural Revolution, Heilongjiang was also expanded to include Hulunbuir League and some other areas previously in Inner Mongolia; this has since mostly been reversed.

Geography

Heilongjiang is a land of varied topographies. Much of the province is dominated by mountain ranges such as the Greater Khingan Range and Lesser Khingan Range, Zhangguangcai Mountains, Laoye Mountains, and Wanda Mountains. The highest peak is Datudingzi Mountain at , located on the border with Jilin province. The Greater Khingan Range contains China's largest remaining virgin forest and is an important area for China's forestry industry.

The east and southwest of the province, which are relatively flat and low in altitude, feature the Muling River, the Naoli River, the Songhua River, the Nen River, and the Mudan River, all tributaries of the Amur, while the northern border forms part of the Amur valley. Xingkai Lake (or Khanka Lake) is found on the border with Russia's Primorsky Krai.

Climate

A humid continental climate ( Köppen ''Dwa'' or ''Dwb'') predominates in the province, though areas in the far north are subarctic (Köppen ''Dwc''). Winters are long and bitter, with an average of in January, and summers are short and warm to very warm with an average of in July. The annual average rainfall is , concentrated heavily in summer. Clear weather is prevalent throughout the year, and in the spring, the Songnen Plain and the Sanjiang Plain provide abundant sources of wind energy.

The province's largest cities include Harbin, Qiqihar, Mudanjiang, Jiamusi, Daqing, Jixi, Shuangyashan, Hegang, Qitaihe, Yichun, and Heihe.

Transport

Roads

Heilongjiang boasts an extensive road network. As of October 2020, it has 165,989 km of expressways, highways and other roads. The Beijing - Harbin Expressway is the most significant expressway corridor to the province, which begins at the Heilongjiang - Jilin border and ends within the Harbin Ring Expressway. The Harbin - Tongjiang Expressway runs northeast and it links far-flung counties within the jurisdiction of Harbin, Jiamusi and other major counties in Northeast Heilongjiang. Near the end of Harbin - Tongjiang Expressway, Jiansanjiang–Heixiazi Island Expressway branches off the main expressway at Jiansanjiang and connects many state-owned farms at the far east of the province before ending near the Sino-Russian border. The Suifenhe - Manzhouli Expressway is another major corridor, it runs southeast to northwest and connects some of the most significant population centers of the province, including Mudanjiang, Harbin, Daqing and Qiqihar, before ending at the Heilongjiang - Inner Mongolia border. The Hegang - Dalian Expressway runs between Hegang and the Heilongjiang - Jilin border in East Heilongjiang, is another major expressway that facilitates the transportation of lumber and coal.

Railways

There are 60 railway lines of around including a section of the Asia-Europe Continental Bridge. The Harbin–Dalian High-Speed Railway, completed in 2012, stretches from Harbin, Heilongjiang's capital, to Dalian in Liaoning province via Changchun and Shenyang comprising 23 stops. It is expected to transport 37 million passengers per year by 2020 and 51 million by 2030.
