Lake Qilihu
Qilu Lake () is a plateau lake in Yunnan Province, in southwestern China. The lake has a total area of about 36.86 square kilometers. The average depth is 4.03 m, with an elevation of 1796.75 m. the water storage capacity is about 1.486×108m3. The lake is named after the Qilu mountain (nowadays called Xiushan), directly south of Tonghai county seat. During the Yuan dynasty, the lake used to be larger and reach up to the base of this mountain. The lake has no outlet rivers, but water can leave the area through karst caves. It has a rich aquatic life, supporting a large population of shrimp, carp, black carp, herring, and catfish.http://history.kunming.cn/index/content/2009-06/30/content_1908616.htm According to local legend, the area around the lake used to be flooded and was called Tonghai.

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 ...

Tonghai County
Tonghai County () is located in Yuxi Prefecture-level City, Yunnan Province, China. Geography Tonghai County occupies the fertile valley of Qilu Lake, surrounded on all sides by mountains. The county seat is located on the south side of the lake, separated from the lake by a mile-wide strip of farmland. The county's southernmost part, including the Dagao Dai and Yi Ethnic Township and Lishan Yi Ethnic Township, is separated from the rest of the county by mountains; it is outside of the Qilu Lake basin, and is drained into the Qu River instead. In 1970, a powerful earthquake struck the area. History The area around Qilu Lake has been inhabited since at least the Neolithic period. In the Tang dynasty it was the base of a general. For many centuries it was the political, economic and military center of southern Yunnan. Soon after the formation of PRC, the area of today's Tonghai County was organized as two counties: Tonghai and Hexi (in the western part of today's Tonghai Cou ...

Yuan Dynasty
The Yuan dynasty (), officially the Great Yuan (; xng, , , literally "Great Yuan State"), was a Mongol-led imperial dynasty of China and a successor state to the Mongol Empire after its division. It was established by Kublai, the fifth khagan-emperor of the Mongol Empire from the Borjigin clan, and lasted from 1271 to 1368. In orthodox Chinese historiography, the Yuan dynasty followed the Song dynasty and preceded the Ming dynasty. Although Genghis Khan had been enthroned with the Han-style title of Emperor in 1206 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 the Battle of Yamen. His realm was, by this point, isolated from the other Mongol-led khanates and controlled most of modern-day China and its surrounding areas, inc ...

Karst
Karst is a topography formed from the dissolution of soluble rocks such as limestone, Dolomite (rock), dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes. However, in regions where the dissolved bedrock is covered (perhaps by debris) or confined by one or more superimposed non-soluble rock strata, distinctive karst features may occur only at subsurface levels and can be totally missing above ground. The study of ''paleokarst'' (buried karst in the stratigraphic column) is important in petroleum geology because as much as 50% of the world's hydrocarbon reserves are hosted in carbonate rock, and much of this is found in porous karst systems. Etymology The English word ''karst'' was borrowed from German language, German in the late 19th century, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shrimp
Shrimp are crustaceans (a form of shellfish) with elongated bodies and a primarily swimming mode of locomotion – most commonly Caridea and Dendrobranchiata of the decapod order, although some crustaceans outside of this order are referred to as "shrimp". More narrow definitions may be restricted to Caridea, to smaller species of either group or to only the marine species. Under a broader definition, ''shrimp'' may be synonymous with prawn, covering stalk-eyed swimming crustaceans with long, narrow muscular tails ( abdomens), long whiskers ( antennae), and slender legs. Any small crustacean which resembles a shrimp tends to be called one. They swim forward by paddling with swimmerets on the underside of their abdomens, although their escape response is typically repeated flicks with the tail driving them backwards very quickly. Crabs and lobsters have strong walking legs, whereas shrimp have thin, fragile legs which they use primarily for perching.Rudloe & Rudloe ...

Carp
Carp are various species of oily freshwater fish from the family Cyprinidae, a very large group of fish native to Europe and Asia. While carp is consumed in many parts of the world, they are generally considered an invasive species in parts of Africa, Australia and most of the United States. Biology The cypriniformes (family Cyprinidae) are traditionally grouped with the Characiformes, Siluriformes, and Gymnotiformes to create the superorder Ostariophysi, since these groups share some common features. These features include being found predominantly in fresh water and possessing Weberian ossicles, an anatomical structure derived from the first five anterior-most vertebrae, and their corresponding ribs and neural crests. The third anterior-most pair of ribs is in contact with the extension of the labyrinth and the posterior with the swim bladder. The function is poorly understood, but this structure is presumed to take part in the transmission of vibrations from the swi ...

Black Carp
The black carp (''Mylopharyngodon piceus'') or Chinese black roach is a species of cyprinid freshwater fish and the sole extant species of the genus ''Mylopharyngodon''. It is native to lakes and rivers in East Asia, ranging from the Amur Basin across China to Vietnam. One of the largest cyprinids in the world, the black carp has a typical length of , though it can reach up to in length and in weight. It is carnivorous and generally feeds on invertebrates such as snails, clams and mussels. Black carp, together with bighead carp, silver carp, and grass carp, make up the culturally important " four famous domestic fishes" used in polyculture in China for over a thousand years. It has also been introduced in the United States as one of the invasive " Asian carps", though it is not as widely distributed worldwide as the other three. In China, black carp is widely cultivated for food and Chinese medicine, being one of the most highly esteemed and expensive domestic food f ...

Herring
Herring are forage fish, mostly belonging to the family of Clupeidae. Herring often move in large schools around fishing banks and near the coast, found particularly in shallow, temperate waters of the North Pacific and North Atlantic Oceans, including the Baltic Sea, as well as off the west coast of South America. Three species of ''Clupea'' (the type genus of the herring family Clupeidae) are recognised, and comprise about 90% of all herrings captured in fisheries. The most abundant of these species is the Atlantic herring, which comprises over half of all herring capture. Fish called herring are also found in the Arabian Sea, Indian Ocean, and Bay of Bengal. Herring played an important role in the history of marine fisheries in Europe, and early in the 20th century, their study was fundamental to the development of fisheries science. These oily fish also have a long history as an important food fish, and are often salted, smoked, or pickled. Herring are also known as ...

Catfish
Catfish (or catfishes; order Siluriformes or Nematognathi) are a diverse group of ray-finned fish. Named for their prominent barbels, which resemble a cat's whiskers, catfish range in size and behavior from the three largest species alive, the Mekong giant catfish from Southeast Asia, the wels catfish of Eurasia, and the piraíba of South America, to detritivores (species that eat dead material on the bottom), and even to a tiny parasitic species commonly called the candiru, ''Vandellia cirrhosa''. Neither the armour-plated types nor the naked types have scales. Despite their name, not all catfish have prominent barbels or "whiskers". Members of the Siluriformes order are defined by features of the skull and swimbladder. Catfish are of considerable commercial importance; many of the larger species are farmed or fished for food. Many of the smaller species, particularly the genus ''Corydoras'', are important in the aquarium hobby. Many catfish are nocturnal, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shippei
A is a bamboo staff which curves slightly, approximately 15 inches (or half a metreKoun, 205-206) long, which is used as a "symbol of a Zen master's authority" in Zen Buddhism.Baroni, 300 In contrast to the '' keisaku'', the shippei was often used as a disciplinary measure for meditating monks. It can often be found at the side of a Zen master in a zendo and is also "one of seven items that make up a Zen monk's equipment." It is fashioned out of two pieces of bamboo that are shaped into the form of a spatula (or short bow), wound with rattan, and lacquered. Sometimes curved in the shape of an S, the shippei may be elaborately decorated with a silk cord or have carving Carving is the act of using tools to shape something from a material by scraping away portions of that material. The technique can be applied to any material that is solid enough to hold a form even when pieces have been removed from it, and ...s. It is still "sometimes employed to hit monks".Hori, 701-702 ...

Soil Erosion
Soil erosion is the denudation or wearing away of the upper layer of soil. It is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice (glaciers), snow, air (wind), plants, and animals (including humans). In accordance with these agents, erosion is sometimes divided into water erosion, glacial erosion, snow erosion, wind (aeolean) erosion, zoogenic erosion and anthropogenic erosion such as tillage erosion. Soil erosion may be a slow process that continues relatively unnoticed, or it may occur at an alarming rate causing a serious loss of topsoil. The loss of soil from farmland may be reflected in reduced crop production potential, lower surface water quality and damaged drainage networks. Soil erosion could also cause sinkholes. Human activities have increased by 10–50 times the rate at which erosion is occurring world-wide. Excessive (or accelerated) erosion causes both "on-site" and "off-site" problem ...
