Review of Short Phrases and Links

    This Review contains major "Loess"- related terms, short phrases and links grouped together in the form of Encyclopedia article.

Definitions

  1. Loess is a highly erosion -prone soil that is susceptible to the forces of wind and water.
  2. Loess is the name for the silty soil that has been deposited by wind storms on the plateau over the ages.
  3. Loess is a yellowish soil blown in from the Inner Mongolian deserts. (Web site)
  4. LOESS is one of many modern modeling methods that build on classical methods, such as linear and nonlinear least squares regression.
  5. LOESS is also prone to the effects of outliers in the data set, like other least squares methods. (Web site)

Wind Action

  1. Loess: Very fine-grained sediments deposited by wind action.

Loess Plateau Region

  1. Technical Abstract: Nowhere in the world is soil erosion as serious as in the Loess Plateau region of China.

Linear

  1. These methods use linear least squares fitting, and a first-degree polynomial (lowess) or a second-degree polynomial (loess).

Data Points

  1. The LOESS fit is complete after regression function values have been computed for each of the n data points. (Web site)

Pleistocene

  1. Glacial outwash during the Pleistocene produced huge volumes of wind-blown silt called loess. (Web site)

Several Areas

  1. Hungary has several areas that are covered by loess.

South

  1. In the south occur patches of loess on which fertile brown- and black-earth soils have developed.

Tundra

  1. The loess or wind-blown dust over that tundra, settled in and around the Rhine Valley, contributing to its current agricultural usefulness.

Sand

  1. Thus, the intercalation of snow during sedimentation of sand and loess does not in itself induce a laminated structure.

Soil Type

  1. Soil type: Marshall and Shelby soils, highly variable with slopes from 2 to 15 per cent, composed of loess and glacial till.

Wind

  1. At the retreat of the glaciers, wind blown powdered rock known as loess was deposited over the whole county, forming thin layers under a meter thick. (Web site)

Dunes

  1. Earthy parent material accumulated through wind action; commonly refers to sandy material in dunes or to loess in blankets on the surface.

Parent Material

  1. Their parent material is generally limestone, loess, or wind-blown sand.

Bedrock

  1. In these areas, beneath the surface deposit of loess is a layer of limestone residuum, underlain by bedrock. (Web site)

Layers

  1. Sometimes there is complete absence of layers in rocks such as Loess.

Sediment

  1. Primary sedimentary structures in loess are subtle, so the true origin of this sediment was for a very long time unclear. (Web site)
  2. The sediment originates primarily from water erosion in the Loess Plateau region of northwest China.

Plateau

  1. Reg. on the north.Two-thirds of the province is composed of plateau, part of the loess plateau.

Deposits

  1. In loess deposits, the presence of T. geyeri shells has been reported since the early Pleistocene [ 14].
  2. Such deposits are often found along riverbeds, beaches, dunes, and areas where windblown silt (loess) and sand have accumulated.

China

  1. The North China Plain, the largest flat lowland area in China, consists of fertile soils derived from loess. (Web site)
  2. Much loess found in the Mississippi Valley, China, and Europe is believed to have been deposited during the Pleistocene Epoch. (Web site)
  3. To the south is Loess Plateau, the third largest plateau in China, covering 600,000 square kilometers (308,881 square miles).

Shanxi

  1. It flows between the Ordos and Gobi Deserts, and then south through steep valleys of yellow loamy soil (loess) between Shanxi and Shaanxi provinces.

Yellow River

  1. The Yellow River, which gets its muddy yellow color from the loess, runs through the northwestern part of the prefecture.
  2. The Yellow River is notable for the large amount of silt it carries—1.6 billion tons annually at the point where it descends from the Loess Plateau.

Shaanxi

  1. Where developed on loess (as in Shaanxi, Shanxi, and Henan provinces), the brown soils are fertile, but they are also subject to heavy erosion. (Web site)
  2. The Loess Plateau and its dusty soil cover almost all of Shanxi, Shaanxi, and Gansu provinces and parts of others.

Squares Regression

  1. LOESS combines much of the simplicity of linear least squares regression with the flexibility of nonlinear regression. (Web site)
  2. Because it is so computationally intensive, LOESS would have been practically impossible to use in the era when least squares regression was being developed. (Web site)

Soil

  1. Most recently wind blown soil, called loess, from the glaciers was deposited on top of the lava flows.
  2. The soil from Normandy has formed in loess and is regarded as susceptible to crusting and highly erodible.
  3. Loess field in Germany Surface-water- gley developed in glacial till, Northern Ireland For other uses, see Soil (disambiguation).

Soils

  1. But it is also highly erodible by water or wind, and soils underlain by loess tend to be excessively drained (droughty).
  2. Silvaner likes marl soils mixed with limestone, loess, loam, and soils of volcanic origin.
  3. The early Chinese developed agriculture on the Loess Plateau because these soils were fertile, porous and easy to work. (Web site)

Loess

  1. The thickest known deposit of loess, 335 meters, is on the Loess Plateau in China.
  2. The moraine landscape of northern Poland contains soils made up mostly of sand or loam, while the ice-age river valleys of the south often contain loess. (Web site)
  3. The Huabei Pingyuan (North China Plain), the largest flat lowland area in China, consists of fertile soils derived from loess. (Web site)
