Emin Valley Steppe
The Emin Valley () is located on the China–Kazakhstan border, in Central Asia. It has an area of about . Its main waterway is the Emil River. Administratively, the Emin Valley occupies areas of Tacheng Prefecture in the Xinjiang Region of north-western China; and in East Kazakhstan Province of eastern Kazakhstan. Ecology The Emin Valley has a steppe ecosystem of mostly grasslands; with two saline lakes, Alakol and Sasykkol; and mountains with temperate climates. The Emin Valley Steppe is a Palearctic ecoregion in the Temperate grasslands, savannas, and shrublands Biome. It lies within the vast and larger Eurasian Steppe. Hydrology Orographically, the Emil Valley is an endorrheic basin. In the north, the Tarbagatai Mountains separate it from the Lake Zaysan basin, which is part of the basin of the Irtysh River, eventually draining into the Arctic Ocean. In the southeast, another series of mountain ranges separate it from the Dzungarian Basin (Gurbantünggüt Desert) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Alakol
Alakol Lake ( kk, Алакөл, , from Turkic "motley lake") is a lake located in the Balkhash-Alakol Basin, part of the Almaty and Shyghyz regions, east central Kazakhstan. Its elevation is above sea level. The lake is the northwest extension of the region known as the Dzhungarian Gate (Alataw Pass), a narrow valley connects the southern uplands of Kazakhstan with arid northwest China. The Dzhungarian Gate is a fault-bounded valley (see vertical line on the image along the southwest side of the lake) where the elevation of the valley floor is between 350 and 450 m above sea level and the peaks of the Dzhungarsky Alatau range (lower left) reach above sea level. Two well-defined alluvial fans are visible where mountain streams cut through the faulted landscape to the southwest of the lake. The surface area of the lake is . It is deep at its maximum depth, with a volume of 58.6 km3. A swampy lowland (just above the center of the photo) connects the northwest end of Lake ...

Orography
Orography is the study of the topographic relief of mountains, and can more broadly include hills, and any part of a region's elevated terrain. Orography (also known as ''oreography'', ''orology'' or ''oreology'') falls within the broader discipline of geomorphology. The term orography comes from the Greek: , hill, , to write. Uses Mountain ranges and elevated land masses have a major impact on global climate. For instance, the elevated areas of East Africa substantially determine the strength of the Indian monsoon.Srinivasan, J., Nanjundiah, Ravi S. and Chakraborty, Arindam (2005Impact of Orography on the Simulation of Monsoon Climate in a General Circulation Model''Indian Institute of Science'' In scientific models, such as general circulation models, orography defines the lower boundary of the model over land. When a river's tributaries or settlements by the river are listed in 'orographic sequence', they are in order from the highest (nearest the source of the river) to the l ...

Ecoregions Of Kazakhstan
An ecoregion (ecological region) or ecozone (ecological zone) is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than a biogeographic realm. 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). Three caveats are appropriate for all bio-geographic mapping approaches. Firstly, no single bio-geographic framework is optimal for all taxa. Ecoregions reflect the best compromise for as many taxa as possible. Sec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Valleys Of Kazakhstan
A valley is an elongated low area often running between hills or mountains, which will typically contain a river or stream running from one end to the other. Most valleys are formed by erosion of the land surface by rivers or streams over a very long period. Some valleys are formed through erosion by glacial ice. These glaciers may remain present in valleys in high mountains or polar areas. At lower latitudes and altitudes, these glacially formed valleys may have been created or enlarged during ice ages but now are ice-free and occupied by streams or rivers. In desert areas, valleys may be entirely dry or carry a watercourse only rarely. In areas of limestone bedrock, dry valleys may also result from drainage now taking place underground rather than at the surface. Rift valleys arise principally from earth movements, rather than erosion. Many different types of valleys are described by geographers, using terms that may be global in use or else applied only locally. ...

Relict Gull
The relict gull or Central Asian gull (''Ichthyaetus relictus'') is a medium-sized gull. It was believed to be an eastern race of the Mediterranean gull until 1971 and was traditionally placed in the genus ''Larus''. Description The gull is 44 to 45 cm long with a stocky, thick body. Non-breeding adults feature uniformly dark-smudged ear-coverts and hind crown, white-tipped wings, prominent, isolated black subterminal markings on outer primaries, and no white leading edge to outer wing. Breeding birds have black hoods (including napes) with grey-brown foreheads, and broad, white, half-moon colouring behind, below, and above their eyes. Their legs are orange and their bills scarlet. The name comes from its status as a relict species.Ming Ma, Ying Chen, Kedeerhan Bayahen, Baowen Hu, Fei Li, Jiaqing Wu, Xiang Gao, Yu Mei"Seasonal changes in the number of Relict Gull (''Larus relictus'') at Ebinur Lake, Western China" ''Journal of Arid Land'', 2010, volume 2, number 2, pp 15 ...

Dalmatian Pelican
The Dalmatian pelican (''Pelecanus crispus'') is the largest member of the pelican family, and perhaps the world's largest freshwater bird, although rivaled in weight and length by the largest swans. They are elegant soaring birds, with wingspans rivaling those of the great albatrosses, and their flocks fly in graceful synchrony. With a range spanning across much of Central Eurasia, from the Mediterranean in the West to the Taiwan Strait in the East, and from the Persian Gulf in the South to Siberia in the North, it is a short-to-medium-distance migrant between breeding and overwintering areas. No subspecies are known to exist over its wide range, but based on size differences, a Pleistocene paleosubspecies, ''P. c. palaeocrispus,'' has been described from fossils recovered at Binagady, Azerbaijan. As with other pelicans, the males are larger than the females, and likewise their diet is mainly fish. Their curly nape feathers, grey legs and silvery-white plumage are distinguish ...

Gurbantünggüt Desert
The Gurbantünggüt Desert ( kk, Құрбантұңғыт шөлі; ug, قۇربانتۈڭغۈت قۇملۇقى, Qurbantüngghüt Qumluqi; zh, s=古尔班通古特沙漠 , t=古爾班通古特沙漠, p=Gǔ'ěrbāntōnggǔtè Shāmò) occupies a large part of the Dzungarian Basin in Northern Xinjiang, in the northwest of the People's Republic of China. It is also called by some sources Dzoosotoyn Elisen Desert, presumably from a Mongolian language. It is about 50,000 square kilometers (19,000 mi2) and around 300 to 600 meters above sea level. It is Xinjiang's second largest desert, after the Taklamakan Desert, which is in the Tarim Basin. A remote rugged area, the Gurbantünggüt Desert is separated by the Tian Shan mountains from the Ili River Basin, Turfan Depression and Tarim Basin of southern Xinjiang. A chain of cities, the largest of which is Ürümqi, are within a populated strip (the route of the Lanxin Railway) south of the desert, which is irrigated by glacier-f ...

Dzungaria
Dzungaria (; from the Mongolian language, Mongolian words , meaning 'left hand') is a geographical subregion in Northwest China that corresponds to the northern half of Xinjiang. It is thus also known as Beijiang, which means "Northern Xinjiang". Bounded by the Altai Mountains to the north and the Tian Shan mountain range to the south, Dzungaria covers approximately , and borders Kazakhstan to the west and Mongolia to the east. In contexts prior to the mid-18th century Dzungar genocide, the term "Dzungaria" could cover a wider area, conterminous with the Oirats, Oirat-led Dzungar Khanate. Although Dzungaria is geographically, historically, and ethnically distinct from the Tarim Basin (or Nanjiang, ), the Manchu people, Manchu-led Qing dynasty integrated both areas into one province, Xinjiang. Dzungaria is Xinjiang's center of heavy industry, generates most of the region's GDP, and houses its political capital Ürümqi (Oirat language, Oirat for 'beautiful pasture'). As such, Dzun ...

Arctic Ocean
The Arctic Ocean is the smallest and shallowest of the world's five major oceans. It spans an area of approximately and is known as the coldest of all the oceans. The International Hydrographic Organization (IHO) recognizes it as an ocean, although some oceanographers call it the Arctic Mediterranean Sea. It has been described approximately as an estuary of the Atlantic Ocean. It is also seen as the northernmost part of the all-encompassing World Ocean. The Arctic Ocean includes the North Pole region in the middle of the Northern Hemisphere and extends south to about 60°N. The Arctic Ocean is surrounded by Eurasia and North America, and the borders follow topographic features: the Bering Strait on the Pacific side and the Greenland Scotland Ridge on the Atlantic side. It is mostly covered by sea ice throughout the year and almost completely in winter. The Arctic Ocean's surface temperature and salinity vary seasonally as the ice cover melts and freezes; its salinity is t ...

Irtysh
The Irtysh ( otk, 𐰼𐱅𐰾:𐰇𐰏𐰕𐰏, Ertis ügüzüg, mn, Эрчис мөрөн, ''Erchis mörön'', "erchleh", "twirl"; russian: Иртыш; kk, Ертіс, Ertis, ; Chinese: 额尔齐斯河, pinyin: ''É'ěrqísī hé'', Xiao'erjing: عَعَرٿِسِ حْ; ug, إيرتيش, Әртиш, ''Ertish''; tt-Cyrl, Иртеш, , , Siberian Tatar: Эйәртеш, ''Eya’rtes’'') is a river in Russia, China, and Kazakhstan. It is the chief tributary of the Ob and is also the second longest tributary river in the world after Paraná River. The river's source lies in the Mongolian Altai in Dzungaria (the northern part of Xinjiang, China) close to the border with Mongolia. The Irtysh's main tributaries include the Tobol, Demyanka and the Ishim. The Ob-Irtysh system forms a major drainage basin in Asia, encompassing most of Western Siberia and the Altai Mountains.
