Dongbei Plain
The Northeast China Plain (), commonly known as Song liao Plain or the Manchurian Plain or just the Northeast Plain, is located in Northeast China, historically also known as Manchuria. 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 km2, 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 it. The Manchurian Plain of Asia is the other name of the Amur valley.Encyclopedia Britannica''Northeast Plain'' Retrieved 12-5-2019. 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 Liaohe, which are collectively know ...

Liaohe Plain
The Liaohe Plain is a paddy plain located in the southern tip of Northeast China, apart of a greater Northeast China Plain. The Liaohe Plain is one of the most important industrial zones in Liaoning Province of China, and, with a cultivated land area of 144 million hectares, the Liaohe Plain rice field station's area of paddy-growing fields have increased by 977.1 square kilometers, located in the center, from 1988 to 2006. Liaohe is located in the golden belt of maize production, and serves as a strategic commodity grain base. Liaohe's average annual July and January temperatures are 8.6 to −9.8 °C for January, and 24.4 for July, with Irrigation generally starting in early May. Cultivation activity include oil and gas exploration, aquaculture, and salt production. Excessive land usage contributed to deformation of the plain, detrimental to the environment and economic construction projects. The adjacent Liaohe River Basin is of the most vulnerable areas to climate cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marsh
A marsh is a wetland that is dominated by herbaceous rather than woody plant species.Keddy, P.A. 2010. Wetland Ecology: Principles and Conservation (2nd edition). Cambridge University Press, Cambridge, UK. 497 p Marshes can often be found at the edges of lakes and streams, where they form a transition between the aquatic and terrestrial ecosystems. They are often dominated by grasses, rushes or reeds. If woody plants are present they tend to be low-growing shrubs, and the marsh is sometimes called a carr. This form of vegetation is what differentiates marshes from other types of wetland such as swamps, which are dominated by trees, and mires, which are wetlands that have accumulated deposits of acidic peat. Marshes provide habitats for many kinds of invertebrates, fish, amphibians, waterfowl and aquatic mammals. This biological productivity means that marshes contain 0.1% of global sequestered terrestrial carbon. Moreover, they have an outsized influence on climate resi ...

Wetland
A wetland is a distinct ecosystem that is flooded or saturated by water, either permanently (for years or decades) or seasonally (for weeks or months). Flooding results in oxygen-free (anoxic) processes prevailing, especially in the soils. The primary factor that distinguishes wetlands from terrestrial land forms or Body of water, water bodies is the characteristic vegetation of aquatic plants, adapted to the unique anoxic hydric soils. Wetlands are considered among the most biologically diverse of all ecosystems, serving as home to a wide range of plant and animal species. Methods for assessing wetland functions, wetland ecological health, and general wetland condition have been developed for many regions of the world. These methods have contributed to wetland conservation partly by raising public awareness of the functions some wetlands provide. Wetlands occur naturally on every continent. The water in wetlands is either freshwater, brackish or seawater, saltwater. The main w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chernozem
Chernozem (from rus, чернозём, p=tɕɪrnɐˈzʲɵm, r=chernozyom; "black ground"), also called black soil, is a black-colored soil containing a high percentage of humus (4% to 16%) and high percentages of phosphorus and ammonia compounds. Chernozem is very fertile soil and can produce high agricultural yields with its high moisture storage capacity. Chernozems are a Reference Soil Group of the World Reference Base for Soil Resources (WRB). Distribution The name comes from the Russian terms for black and soil, earth or land (''chorny'' + ''zemlya''). The soil, rich in organic matter presenting a black color, was first identified by Russian geologist Vasily Dokuchaev in 1883 in the tallgrass steppe or prairie of European Russia. Chernozem cover about 230 million hectares of land. There are two "chernozem belts" in the world. One is the Eurasian steppe which extends from eastern Croatia (Slavonia), along the Danube (northern Serbia, northern Bulgaria ( Danubian Pla ...

Guangxu Emperor
The Guangxu Emperor (14 August 1871 – 14 November 1908), personal name Zaitian, was the tenth Emperor of the Qing dynasty, and the ninth Qing emperor to rule over China proper. His reign lasted from 1875 to 1908, but in practice he ruled, without Empress Dowager Cixi's influence, only from 1889 to 1898. He initiated the Hundred Days' Reform, but was abruptly stopped when the empress dowager launched a coup in 1898, after which he became powerless and was held under house arrest until his death by poisoning. His era name, "Guangxu", means "glorious succession". The emperor died in 1908 and it was widely suspected at the time that he had been poisoned. A forensic examination on his remains confirmed in 2008 that the cause of death was arsenic poisoning. The level of arsenic in his remains was 2,000 times higher than normal. Accession to the throne and upbringing Zaitian was the second son of Yixuan (Prince Chun), and his primary spouse Yehenara Wanzhen, a younger sister of ...

Chuang Guandong
''Chuang Guandong'' (; IPA: ; literally "Crashing into Guandong" with ''Guandong'' being an older name for Manchuria) is descriptive of the rush of Han people into Manchuria, mainly from the Shandong Peninsula and Zhili, during the hundred-year period beginning in the last half of the 19th century. During the first two centuries of the Manchu-led Qing dynasty, this part of China, the traditional homeland of the ruling Manchus, was, with few exceptions, closed to settlement by Han civilians, with only certain Manchu bannermen, Mongol bannermen, and Han bannermen allowed in. The region, now known as Northeast China, now has an overwhelmingly Han population. Historical background Inner Manchuria, also called Guandong (literally, "east of the pass" referring to Shanhai Pass at the east end of the Great Wall of China) or Guanwai (), used to be a land of sparse population, inhabited mainly by the Tungusic peoples. In 1668 during the reign of the Kangxi Emperor, the Qing government decre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Han Chinese
The Han Chinese () or Han people (), are an East Asian ethnic group native to China. They constitute the world's largest ethnic group, making up about 18% of the global population and consisting of various subgroups speaking distinctive varieties of the Chinese language. The estimated 1.4 billion Han Chinese people, worldwide, are primarily concentrated in the People's Republic of China (including Mainland China, Hong Kong and Macau) where they make up about 92% of the total population. In the Republic of China (Taiwan), they make up about 97% of the population. People of Han Chinese descent also make up around 75% of the total population of Singapore. Originating from Northern China, the Han Chinese trace their cultural ancestry to the Huaxia, the confederation of agricultural tribes living along the Yellow River. This collective Neolithic confederation included agricultural tribes Hua and Xia, hence the name. They settled along the Central Plains around the middle and lo ...

Jurchen People
Jurchen (Manchu: ''Jušen'', ; zh, 女真, ''Nǚzhēn'', ) is a term used to collectively describe a number of East Asian Tungusic-speaking peoples, descended from the Donghu people. They lived in the northeast of China, later known as Manchuria, before the 18th century. The Jurchens were renamed Manchus in 1635 by Hong Taiji. Different Jurchen groups lived as hunter-gatherers, pastoralist semi-nomads, or sedentary agriculturists. Generally lacking a central authority, and having little communication with each other, many Jurchen groups fell under the influence of neighbouring dynasties, their chiefs paying tribute and holding nominal posts as effectively hereditary commanders of border guards. Chinese officials of the Ming dynasty (1368-1644) classified them into three groups, reflecting relative proximity to China: # Jianzhou (Chinese: 建州) Jurchens, some of whom were mixed with Korean and Chinese populations, lived in the proximity of the Mudan river, the Changbai mo ...

Zhou Dynasty
The Zhou dynasty ( ; Old Chinese ( B&S): *''tiw'') was a royal dynasty of China that followed the Shang dynasty. Having lasted 789 years, the Zhou dynasty was the longest dynastic regime in Chinese history. The military control of China by the royal house, surnamed Ji, lasted initially from 1046 until 771 BC for a period known as the Western Zhou, and the political sphere of influence it created continued well into the Eastern Zhou period for another 500 years. The establishment date of 1046 BC is supported by the Xia–Shang–Zhou Chronology Project and David Pankenier, but David Nivison and Edward L. Shaughnessy date the establishment to 1045 BC. During the Zhou dynasty, centralized power decreased throughout the Spring and Autumn period until the Warring States period in the last two centuries of the dynasty. In the latter period, the Zhou court had little control over its constituent states that were at war with each other until the Qin state consolidated power and forme ...

Sushen
Sushen is the modern Chinese name for an ancient ethnic group of people who lived in the northeastern part of China (in the area of modern Jilin and Heilongjiang) and what is in modern times the Russian Maritime Province and some other Siberian provinces. They were active during the Zhou Dynasty period. Archeological relics in the area are attributed to the Xituanshan Culture. Chinese Bronze Age archaeologist Zou Heng of Peking University believed that the Sushen were also related to the Lower Xiajiadian culture. The Sushen are thought to have been Tungusic speakers. According to the ''Guoyu'' and the ''Classic of Mountains and Seas'' published in the Warring States period (476–221 BCE), Sushen was the name of the tribe who lived in Shandong and border of Liaoxi Province. The name's characters appeared as early as the 6th century BC in Chinese documents. They are almost unknown with the exception of the fact that they lived to the north of China and used flint-headed woo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ussuri River
The Ussuri or Wusuli (russian: Уссури; ) is a river that runs through Khabarovsk and Primorsky Krais, Russia and the southeast region of Northeast China. 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 to it near Khabarovsk. It is approximately long. The Ussuri drains the Ussuri basin, which covers . Its waters come from rain (60%), snow (30–35%), and subterranean springs. The average discharge is , and the average elevation is . Names The Ussuri has been known by many names. In Manchu, it was called the Usuri Ula or Dobi Bira (River of Foxes) and in Mongolian the Üssüri Müren. ''Ussuri'' is Manchu for ''soot-black river''. History * The Ussuri has a reputation for catastrophic floods. It freezes up in November and stays under the ice until April. The river teems with different kinds of fish: gray ...
