Huang He Plain Mixed Forests
The Huang He Plain mixed forests ecoregion (WWF ID: PA0424) covers the flat lower ranges of the Yellow River ("Huang He" means Yellow River). This area is generally known as the North China Plain. While there is some forest habitat, the region has mostly been converted to agriculture, being one of the most populous areas in the world (approximately 190 million people). Location and description The Huang He Mixed Forests ecoregion covers the North China plain, a large alluvial plain which collects the deposits of the lower reaches of the Yellow River, the Huai River, and the Hai River. The plain is very flat, and averages only 50 meters above sea level. Almost 3% of the land area is urbanized. Climate The climate of the ecoregion is '' Humid continental climate, hot summer'' (Köppen climate classification (Dwa)), with a dry winter. This climate is characterized by large seasonal temperature differentials and a hot summer (at least four months averaging over , at least ...

Palearctic
The Palearctic or Palaearctic is a biogeographic realm of the Earth, the largest of eight. Confined almost entirely to the Eastern Hemisphere, it stretches across Europe and Asia, north of the foothills of the Himalayas, and North Africa. The realm consists of several bioregions: the Mediterranean Basin; North Africa; North Arabia; Western, Central and East Asia. The Palaearctic realm also has numerous rivers and lakes, forming several freshwater ecoregions. Both the eastern and westernmost extremes of the Paleartic span into the Western Hemisphere, including Cape Dezhnyov in Chukotka Autonomous Okrug to the east and Iceland to the west. The term was first used in the 19th century, and is still in use as the basis for zoogeographic classification. History In an 1858 paper for the ''Proceedings of the Linnean Society'', British zoologist Philip Sclater first identified six terrestrial zoogeographic realms of the world: Palaearctic, Aethiopian/ Afrotropic, Indian/ I ...

Temperate Broadleaf And Mixed Forest
Temperate broadleaf and mixed forest is a temperate climate terrestrial habitat type defined by the World Wide Fund for Nature, with broadleaf tree ecoregions, and with conifer and broadleaf tree mixed coniferous forest ecoregions. These forests are richest and most distinctive in central China and eastern North America, with some other globally distinctive ecoregions in the Himalayas, Western and Central Europe, the southern coast of the Black Sea, Australasia, Southwestern South America and the Russian Far East. Ecology The typical structure of these forests includes four layers. * The uppermost layer is the canopy composed of tall mature trees ranging from high. Below the canopy is the three-layered, shade-tolerant understory that is roughly shorter than the canopy. * The top layer of the understory is the sub-canopy composed of smaller mature trees, saplings, and suppressed juvenile canopy layer trees awaiting an opening in the canopy. * Below the sub-canop ...

Ecoregion
An ecoregion (ecological region) is an ecological and geographic area that exists on multiple different levels, defined by type, quality, and quantity of environmental resources. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species. The biodiversity of flora, fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation (largely undefined at this point). Ecoregions are also known as "ecozones" ("ecological zones"), although that term may also refer to biogeographic realms. Three caveats are appropriate for all bio-geographic mapping approaches. Firstly, no single bio-geographic fram ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yellow River
The Yellow River, also known as Huanghe, is the second-longest river in China and the List of rivers by length, sixth-longest river system on Earth, with an estimated length of and a Drainage basin, watershed of . Beginning in the Bayan Har Mountains, the river flows generally eastwards before entering the long Ordos Loop, which runs northeast at Gansu through the Ordos Plateau and turns east in Inner Mongolia. The river then turns sharply southwards to form the border between Shanxi and Shaanxi, turns eastwards at its confluence with the Wei River, and flows across the North China Plain before emptying into the Bohai Sea. The river is named for the yellow color of its water, which comes from the large amount of sediment discharged into the water as the river flows through the Loess Plateau. The Yellow River basin was the birthplace of Yellow River civilization, ancient Chinese civilization. According to traditional Chinese historiography, the Xia dynasty originated on it ...

North China Plain
The North China Plain () is a large-scale downfaulted rift basin formed in the late Paleogene and Neogene and then modified by the deposits of the Yellow River. It is the largest alluvial plain of China. The plain is bordered to the north by the Yanshan Mountains, to the west by the Taihang Mountains, to the south by the Dabie Mountains, and to the east by the Yellow Sea and Bohai Sea. The Yellow River flows through the plain, before its waters empty into the Bohai Sea. The part of the North China Plain around the banks of the middle and lower Yellow River is commonly referred to as the Central Plain (). This portion of the North China Plain formed the cradle of Chinese civilization, and is the region from which the Han Chinese people emerged. ...

Huai River
The Huai River, formerly romanized as the Hwai, is a major river in East China, about long with a drainage area of . It is located about midway between the Yellow River and Yangtze River, the two longest rivers and largest drainage basins in China. Historically draining eastwards directly into the Yellow Sea, erosion from floods have changed the course of the river such that it now primarily discharges into the Yangtze. The Huai River is, to this day, notoriously vulnerable to flooding. The Qinling–Huaihe Line, formed by the Huai River and the Qin Mountains, is sometimes regarded as the geographical dividing line between northern and southern China. This line approximates the January isotherm and the isohyet in China. Course The Huai River originates in Tongbai Mountain in Henan province. It flows through southern Henan, northern Anhui, and northern Jiangsu where it pools into Lake Hongze. Nowadays the Huai River then runs southwards as the Sanhe River by w ...

Hai River
The Hai River (海河, lit. "Sea River"), also known as the Peiho, ("White River"), or Hai Ho, is a Chinese river connecting Beijing to Tianjin and the Bohai Sea. During the Song dynasty, the main stream of the Hai River was called the lower section of the Jie River. In the Jin and Yuan dynasties, it was renamed as Zhígǔ River (直沽河, lit. “Straight Gu River") and Dàgǚ River (大沽河, lit. “Great Gu River") respectively. The name Hai River first appeared towards the end of the Ming dynasty. The Hai River at Tianjin is formed by the confluence of five watercourses: the Southern Canal, Ziya River, Daqing River, Yongding River, and the Northern Canal. The southern and northern canals are parts of the Grand Canal. The Southern Canal is joined by the Wei River at Linqing. The Northern Canal joins with the Bai He (or Chaobai River) at Tongzhou. The Northern Canal (sharing a channel with Bai He) is also the only waterway from the sea to Beijing. Therefore, earl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Humid Continental Climate
A humid continental climate is a climatic region defined by Russo-German climatologist Wladimir Köppen in 1900, typified by four distinct seasons and large seasonal temperature differences, with warm to hot (and often humid) summers, and cold (sometimes severely cold in the northern areas) and snowy winters. Precipitation is usually distributed throughout the year, but often these regions do have dry seasons. The definition of this climate in terms of temperature is as follows: the mean temperature of the coldest month must be below or depending on the isotherm, and there must be at least four months whose mean temperatures are at or above . In addition, the location in question must not be semi-arid or arid. The cooler ''Dfb'', ''Dwb'', and ''Dsb'' subtypes are also known as hemiboreal climates. Although amount of snowfall is not a factor used in defining the humid continental climate, snow during the winter in this type of climate is almost a guarantee, either intermitte ...

Köppen Climate Classification
The Köppen climate classification divides Earth climates into five main climate groups, with each group being divided based on patterns of seasonal precipitation and temperature. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indicates a tropical rainforest climate. The system assigns a temperature subgroup for all groups other than those in the ''A'' group, indicated by the third letter for climates in ''B'', ''C'', ''D'', and the second letter for climates in ''E''. Other examples include: ''Cfb'' indicating an oceanic climate with warm summers as indicated by the ending ''b.'', while ''Dwb'' indicates a semi-Monsoon continental climate, monsoonal continental climate ...
