Tengger Desert
The Tengger Desert or Tengri Desert ( mn, Тэнгэр цөл, ) is an arid natural region that covers about 36,700 km2 and is mostly in the Inner Mongolia Autonomous Region in China. The desert is expanding in size.Haner, Josh, et al. (24 October 2016)Living in China's Expanding Deserts ''The New York Times'' Environmental issues The expansion of the Tengger and its neighbour, the Badain Jaran Desert, has been apparent since the 1950s, when large volumes of water were diverted from rivers to feed agricultural expansion and huge tracts of forest were removed. Since 1958, local governments have mobilised residents for afforestation campaigns to prevent the desert's spread. By 2004, the desert's expansion was estimated as 10 metres per year in some areas. In 2007, a non-profit organisation founded by residents of Minqin County created square ditches lined with hay and grass that they later planted with saxaul to stabilise the sand dunes. In 2010, the central and regional gove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Desert
A desert is a barren area of landscape where little precipitation occurs and, consequently, living conditions are hostile for plant and animal life. The lack of vegetation exposes the unprotected surface of the ground to denudation. About one-third of the land surface of the Earth is arid or semi-arid. This includes much of the polar regions, where little precipitation occurs, and which are sometimes called polar deserts or "cold deserts". Deserts can be classified by the amount of precipitation that falls, by the temperature that prevails, by the causes of desertification or by their geographical location. Deserts are formed by weathering processes as large variations in temperature between day and night put strains on the rocks, which consequently break in pieces. Although rain seldom occurs in deserts, there are occasional downpours that can result in flash floods. Rain falling on hot rocks can cause them to shatter, and the resulting fragments and rubble strewn over ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reforestation
Reforestation (occasionally, reafforestation) is the natural or intentional restocking of existing forests and woodlands ( forestation) that have been depleted, usually through deforestation, but also after clearcutting. Management A debated issue in managed reforestation is whether or not the succeeding forest will have the same biodiversity as the original forest. If the forest is replaced with only one species of tree and all other vegetation is prevented from growing back, a monoculture forest similar to agricultural crops would be the result. However, most reforestation involves the planting of different selections of seedlings taken from the area, often of multiple species. Another important factor is the natural regeneration of a wide variety of plant and animal species that can occur on a clear cut. In some areas the suppression of forest fires for hundreds of years has resulted in large single aged and single species forest stands. The logging of small clear cuts ...

Ergs
The erg is a unit of energy equal to 10−7joules (100 nJ). It originated in the Centimetre–gram–second system of units (CGS). It has the symbol ''erg''. The erg is not an SI unit. Its name is derived from (), a Greek word meaning 'work' or 'task'. An erg is the amount of work done by a force of one dyne exerted for a distance of one centimetre. In the CGS base units, it is equal to one gram centimetre-squared per second-squared (g⋅cm2/s2). It is thus equal to 10−7 joules or 100 nanojoules ( nJ) in SI units. * 1 erg = = * 1 erg = = = * 1 erg = = * 1 erg = = * 1 erg = History In 1864, Rudolf Clausius proposed the Greek word () for the unit of energy, work and heat. In 1873, a committee of the British Association for the Advancement of Science, including British physicists James Clerk Maxwell and William Thomson recommended the general adoption of the centimetre, the gramme, and the second as fundamental units ( C.G.S. System of Units). To distinguish der ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geography Of Inner Mongolia
Inner Mongolia, officially the Inner Mongolia Autonomous Region, is an autonomous region of the People's Republic of China. Its border includes most of the length of China's border with the country of Mongolia. Inner Mongolia also accounts for a small section of China's border with Russia ( Zabaykalsky Krai). Its capital is Hohhot; other major cities include Baotou, Chifeng, Tongliao, and Ordos. The autonomous region was established in 1947, incorporating the areas of the former Republic of China provinces of Suiyuan, Chahar, Rehe, Liaobei, and Xing'an, along with the northern parts of Gansu and Ningxia. Its area makes it the third largest Chinese administrative subdivision, constituting approximately and 12% of China's total land area. Due to its long span from east to west, Inner Mongolia is geographically divided into eastern and western divisions. The eastern division is often included in Northeastern China (Dongbei) with major cities including Tongliao, C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Green Belt
A green belt is a policy and land-use zone designation used in land-use planning to retain areas of largely undeveloped, wilderness, wild, or agricultural landscape, land surrounding or neighboring urban areas. Similar concepts are greenway (landscape), greenways or green wedges, which have a linear character and may run through an urban area instead of around it. In essence, a green belt is an invisible line designating a border around a certain area, preventing development of the area and allowing wildlife to return and be established. Purposes In those countries which have them, the stated objectives of green belt policy are to: * Protect natural or semi-natural environments; * Improve air quality within urban area, urban areas; * Ensure that urban dwellers have access to countryside, with consequent educational and recreational opportunities; * Protect the unique character of rural communities that might otherwise be absorbed by expanding suburbs.

Minqin County
Minqin County () is a county of Gansu province, the People's Republic of China. It is under the jurisdiction of Wuwei City. Its postal code is 733300, and its population in 1999 was 281,826 people. In older literature, today's Minqin is referred to as Zhenfan (). According to Pyotr Kozlov, the Mongol name for the city was Sogo Khoto. Geographically, Minqin county occupies one of Gansu's panhandles, bordering in the north, east, and southeast on the Alashan League of Inner Mongolia. History Historically, Chinese agricultural settlement in the area was made possible by the Shiyang River, flowing from the Qilian Mountains. However, the livelihood of Chinese farmers here was often precarious; in the 1920s it was considered as somewhat of a regular famine district.Owen Lattimore, ''The Desert Road to Turkestan''. London, Methuen, 1928. Large number of Zhenfan people, nicknamed "Sand-hollow Mice", worked as "camel-pullers" with caravans owned by Mongols from the adjacent Alasha ...
