History Of The Great Wall Of China
The history of the Great Wall of China began when fortifications built by various states during the Spring and Autumn (771–476BC) and Warring States periods (475–221BC) were connected by the first emperor of China, Qin Shi Huang, to protect his newly founded Qin dynasty (221–206BC) against incursions by nomads from Inner Asia. The walls were built of rammed earth, constructed using forced labour, and by 212 BC ran from Gansu to the coast of southern Manchuria. Later dynasties adopted different policies towards northern frontier defense. The Han (202BC – 220AD), the Northern Qi (550–574), the Jurchen-ruled Jin (1115–1234), and particularly the Ming (1369–1644) were among those that rebuilt, re-manned, and expanded the Walls, although they rarely followed Qin's routes. The Han extended the fortifications furthest to the west, the Qi built about of new walls, while the Sui mobilised over a million men in their wall-building efforts. Conversely, the Tang ...

Map Of The Great Wall Of China
A map is a symbolic depiction of interrelationships, commonly spatial, between things within a space. A map may be annotated with text and graphics. Like any graphic, a map may be fixed to paper or other durable media, or may be displayed on a transitory medium such as a computer screen. Some maps change interactively. Although maps are commonly used to depict geography, geographic elements, they may represent any space, real or fictional. The subject being mapped may be two-dimensional such as Earth's surface, three-dimensional such as Earth's interior, or from an abstract space of any dimension. Maps of geographic territory have a very long tradition and have existed from ancient times. The word "map" comes from the , wherein ''mappa'' meant 'napkin' or 'cloth' and ''mundi'' 'of the world'. Thus, "map" became a shortened term referring to a flat representation of Earth's surface. History Maps have been one of the most important human inventions for millennia, allowin ...

Yuan Dynasty
The Yuan dynasty ( ; zh, c=元朝, p=Yuáncháo), officially the Great Yuan (; Mongolian language, Mongolian: , , literally 'Great Yuan State'), was a Mongol-led imperial dynasty of China and a successor state to the Mongol Empire after Division of the Mongol Empire, its division. It was established by Kublai (Emperor Shizu or Setsen Khan), the fifth khagan-emperor of the Mongol Empire from the Borjigin clan, and lasted from 1271 to 1368. In Chinese history, the Yuan dynasty followed the Song dynasty and preceded the Ming dynasty. Although Genghis Khan's enthronement as Khagan in 1206 was described in Chinese language, Chinese as the Han Chinese, Han-style title of Emperor of China, Emperor and the Mongol Empire had ruled territories including modern-day northern China for decades, it was not until 1271 that Kublai Khan officially proclaimed the dynasty in the traditional Han style, and the conquest was not complete until 1279 when the Southern Song dynasty was defeated in t ...

Scholar-official
The scholar-officials, also known as literati, scholar-gentlemen or scholar-bureaucrats (), were government officials and prestigious scholars in Chinese society, forming a distinct social class. Scholar-officials were politicians and government officials appointed by the emperor of China to perform day-to-day political duties from the Han dynasty to the end of the Qing dynasty in 1912, China's last imperial dynasty. After the Sui dynasty these officials mostly came from the Landed gentry in China, scholar-gentry (紳士 ''shēnshì'') who had earned academic degrees (such as ''xiucai'', ''juren'', or ''Jinshi (imperial examination), jinshi'') by passing the imperial examinations. Scholar-officials were the elite class of imperial China. They were highly educated, especially in literature and the arts, including calligraphy and Confucianism, Confucian texts. They dominated the government administration and local life of China until the early 20th century. Origins and formations ...

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 ...

Loess
A loess (, ; from ) is a clastic rock, clastic, predominantly silt-sized sediment that is formed by the accumulation of wind-blown dust. Ten percent of Earth's land area is covered by loesses or similar deposition (geology), deposits. A loess is a periglacial or aeolian processes, aeolian (windborne) sediment, defined as an accumulation of 20% or less of clay with a balance of roughly equal parts sand and silt (with a typical grain size from 20 to 50 micrometers), often loosely cemented by calcium carbonate. Usually, they are homogeneity and heterogeneity, homogeneous and highly Porosity#Porosity in earth sciences and construction, porous and have vertical capillaries that permit the sediment to fracture and form vertical cliff, bluffs.

Karl August Wittfogel
Karl August Wittfogel (; 6 September 1896 – 25 May 1988) was a German-American playwright, historian, and sinologist. He was originally a Marxist and an active member of the Communist Party of Germany, but after the Second World War, he was an equally fierce anticommunist. Life and career Karl August Wittfogel was born 6 September 1896 at Woltersdorf, in Lüchow, Province of Hanover to a Lutheran schoolteacher. Wittfogel left school in 1914. He studied philosophy, history, sociology, geography at Leipzig University and also in Munich, Berlin and Rostock and in 1919 again in Berlin. From 1921 he studied sinology in Leipzig. In between Wittfogel was drafted into a Signal Corps Unit (''Fernmeldeeinheit'') in 1917. In 1921 Wittfogel married Rose Schlesinger. Wittfogel's second wife was Olga (Joffe) Lang, a Russian sociologist who traveled with him to China and collaborated with him on a project to analyze the Chinese family. Lang later published a monograph on the Chinese ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semi-arid Climate
A semi-arid climate, semi-desert climate, or steppe climate is a dry climate sub-type. It is located on regions that receive precipitation below potential evapotranspiration, but not as low as a desert climate. There are different kinds of semi-arid climates, depending on variables such as temperature, and they give rise to different biomes. Defining attributes of semi-arid climates A more precise definition is given by the Köppen climate classification, which treats steppe climates (''BSh'' and ''BSk'') as intermediates between desert climates (BW) and humid climates (A, C, D) in ecological characteristics and agricultural potential. Semi-arid climates tend to support short, thorny or scrubby vegetation and are usually dominated by either grasses or shrubs as they usually cannot support forests. To determine if a location has a semi-arid climate, the precipitation threshold must first be determined. The method used to find the precipitation threshold (in millimeters): * ...

Isohyet
A contour line (also isoline, isopleth, isoquant or isarithm) of a function of two variables is a curve along which the function has a constant value, so that the curve joins points of equal value. It is a plane section of the three-dimensional graph of the function f(x,y) parallel to the (x,y)-plane. More generally, a contour line for a function of two variables is a curve connecting points where the function has the same particular value. In cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. A contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes. The contour interval of a contour map is the difference in elevation between successive contour lines. The gradient of the function is always perpendicular to the contour lines. When the lines are close together the magnitude of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gobi Desert Map
The Gobi Desert (, , ; ) is a large, cold desert and grassland region in North China and southern Mongolia. It is the sixth-largest desert in the world. The name of the desert comes from the Mongolian word ''gobi'', used to refer to all of the waterless regions in the Mongolian Plateau; in Chinese, ''gobi'' is used to refer to rocky, semi-deserts such as the Gobi itself rather than sandy deserts. Geography The Gobi measures from southwest to northeast and from north to south. The desert is widest in the west, along the line joining the Lake Bosten and the Lop Nor (87°–89° east). Its area is approximately . Gobi includes the long stretch of desert extending from the foot of the Pamirs (77° east) to the Greater Khingan Mountains, 116–118° east, on the border of Manchuria; and from the foothills of the Altay, Sayan, and Yablonoi mountain ranges on the north to the Kunlun, Altyn-Tagh, and Qilian mountain ranges, which form the northern edges of the Tibetan Plateau, ...

China Proper
China proper, also called Inner China, are terms used primarily in the West in reference to the traditional "core" regions of China centered in the southeast. The term was first used by Westerners during the Manchu people, Manchu-led Qing dynasty to describe the distinction between the historical "Han lands" ( zh, t=漢地, i.e. regions long dominated by the majority Han Chinese, Han population) and the "frontier" regions of China where more ethnic minorities in China, non-Han ethnic minorities and newer foreign immigrants (e.g. Russians) reside, sometimes known as "Outer China". There is no fixed extent for China ''proper'', as many administrative, cultural, and linguistic shifts have occurred in History of China, Chinese history. One definition refers to the original area of Chinese civilization, the Zhongyuan, Central Plain (in the North China Plain); another to the Eighteen Provinces of the Qing dynasty. There was no direct translation for "China ''proper''" in the Chinese ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
