Lop Desert
The Lop Desert, or the Lop Depression, is a desert extending from Korla eastwards along the foot of the Kuruk-tagh (meaning Dry Mountain) to the former terminal Tarim Basin in the Xinjiang Uyghur Autonomous Region of China. It is an almost perfectly flat expanse with no topographic relief. Lake Bosten in the northwest lies at an altitude of , while the Lop Nur in the southeast is only 250 m lower. Geography The Lop Desert is on the whole flat, but with three slightly more depressed areas which might form lakes if filled with water - the Lop Nor dried basin, Kara-Koshun dried basin and the Taitema Lake basin. These formed, at one time or another, the terminal lakes of the Tarim-Konque- Qarqan river system. The Tarim River changes its course through time, and therefore the location of the terminal lake also changes, causing some confusion amongst the early explorers as to the exact location of Lop Nor, and the lake was thus referred to as the "Wandering Lake." In the past Lop Nur w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or dyna ...

Qing Dynasty
The Qing dynasty ( ), officially the Great Qing,, was a Manchu-led imperial dynasty of China and the last orthodox dynasty in Chinese history. It emerged from the Later Jin dynasty founded by the Jianzhou Jurchens, a Tungusic-speaking ethnic group who unified other Jurchen tribes to form a new "Manchu" ethnic identity. The dynasty was officially proclaimed in 1636 in Manchuria (modern-day Northeast China and Outer Manchuria). It seized control of Beijing in 1644, then later expanded its rule over the whole of China proper and Taiwan, and finally expanded into Inner Asia. The dynasty lasted until 1912 when it was overthrown in the Xinhai Revolution. In orthodox Chinese historiography, the Qing dynasty was preceded by the Ming dynasty and succeeded by the Republic of China. The multiethnic Qing dynasty lasted for almost three centuries and assembled the territorial base for modern China. It was the largest imperial dynasty in the history of China and in 1790 the f ...

Shiji
''Records of the Grand Historian'', also known by its Chinese name ''Shiji'', is a monumental history of China that is the first of China's 24 dynastic histories. The ''Records'' was written in the early 1st century by the ancient Chinese historian Sima Qian, whose father Sima Tan had begun it several decades earlier. The work covers a 2,500-year period from the age of the legendary Yellow Emperor to the reign of Emperor Wu of Han in the author's own time, and describes the world as it was known to the Chinese of the Western Han dynasty. The ''Records'' has been called a "foundational text in Chinese civilization". After Confucius and the First Emperor of Qin, "Sima Qian was one of the creators of Imperial China, not least because by providing definitive biographies, he virtually created the two earlier figures." The ''Records'' set the model for all subsequent dynastic histories of China. In contrast to Western historical works, the ''Records'' do not treat history as "a conti ...

Li (unit)
''Li'' (, ''lǐ'', or , ''shìlǐ''), also known as the Chinese mile, is a traditional Chinese unit of distance. The li has varied considerably over time but was usually about one third of an English mile and now has a standardized length of a half-kilometer (). This is then divided into 1,500 chi or "Chinese feet". The character 里 combines the characters for "field" ( 田, ''tián'') and "earth" ( 土, ''tǔ''), since it was considered to be about the length of a single village. As late as the 1940s, a "li" did not represent a fixed measure but could be longer or shorter depending on the ''effort'' required to cover the distance. There is also another ''li'' (Traditional: 釐, Simplified: 厘, ''lí'') that indicates a unit of length of a ''chi'', but it is used much less commonly. This ''li'' is used in the People's Republic of China as the equivalent of the ''centi-'' prefix in metric units, thus ''limi'' ( 厘米, límǐ) for centimeter. The tonal difference makes i ...

Book Of Han
The ''Book of Han'' or ''History of the Former Han'' (Qián Hàn Shū,《前汉书》) is a history of China finished in 111AD, covering the Western, or Former Han dynasty from the first emperor in 206 BCE to the fall of Wang Mang in 23 CE. It is also called the ''Book of Former Han''. The work was composed by Ban Gu (32–92 CE), an Eastern Han court official, with the help of his sister Ban Zhao, continuing the work of their father, Ban Biao. They modeled their work on the ''Records of the Grand Historian'', a cross-dynastic general history, but theirs was the first in this annals-biography form to cover a single dynasty. It is the best source, sometimes the only one, for many topics such as literature in this period. A second work, the '' Book of the Later Han'' covers the Eastern Han period from 25 to 220, and was composed in the fifth century by Fan Ye (398–445). Contents This history developed from a continuation of Sima Qian's ''Records of the Grand Historian'', ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tamarix
The genus ''Tamarix'' (tamarisk, salt cedar, taray) is composed of about 50–60 species of flowering plants in the family Tamaricaceae, native to drier areas of Eurasia and Africa. The generic name originated in Latin and may refer to the Tamaris River in Hispania Tarraconensis (Spain). Description They are evergreen or deciduous shrubs or trees growing to in height and forming dense thickets. The largest, ''Tamarix aphylla'', is an evergreen tree that can grow to tall. They usually grow on saline soils, tolerating up to 15,000 ppm soluble salt, and can also tolerate alkaline conditions. Tamarisks are characterized by slender branches and grey-green foliage. The bark of young branches is smooth and reddish brown. As the plants age, the bark becomes gray-brown, ridged and furrowed. The leaves are scale-like, almost like that of junipers, 1–2 mm (1/20" to 1/10") long, and overlap each other along the stem. They are often encrusted with salt secretions. The pink to w ...

Populus
''Populus'' is a genus of 25–30 species of deciduous flowering plants in the family Salicaceae, native to most of the Northern Hemisphere. English names variously applied to different species include poplar (), aspen, and cottonwood. The western balsam poplar ('' P. trichocarpa'') was the first tree to have its full DNA code determined by DNA sequencing, in 2006. Description The genus has a large genetic diversity, and can grow from tall, with trunks up to in diameter. The bark on young trees is smooth, white to greenish or dark gray, and often has conspicuous lenticels; on old trees, it remains smooth in some species, but becomes rough and deeply fissured in others. The shoots are stout, with (unlike in the related willows) the terminal bud present. The leaves are spirally arranged, and vary in shape from triangular to circular or (rarely) lobed, and with a long petiole; in species in the sections ''Populus'' and ''Aigeiros'', the petioles are laterally flattened, s ...
