Min River (Sichuan)
The Min River or Min Jiang () is a in central Sichuan province, China. It is a tributary of the upper Yangtze River which it joins at Yibin. Within China, it was traditionally taken as the main course of the upper Yangtze prior to extensive exploration of its sources. Geography The Min River flows in the general southern direction. It starts in north-central Sichuan, where its basin is limited by the Qionglai Mountains in the west and the Min Mountains in the east. The river passes through the Longmen Mountains and enters the plains of the Sichuan Basin near Dujiangyan. In that area, the ancient Irrigation System and the modern Zipingpu dam are located. The Giant Buddha of Leshan is built into the stone banks of the Min river. Names Some 19th-century Western authors used the name Blue River as the "colloquial name" for the Minjiang, after the former local Chinese name ''Qingshui'' (, lit. "Clear water"), and the belief that the Min constituted the main course of the Yang ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Min River (Fujian)
The Min River (; Foochow Romanized: ''Mìng-gĕ̤ng''; Pe̍h-ōe-jī: Bân-kang; Kienning Colloquial Romanized: Ma̿ing-gó̤ng) is a -long river in Fujian province, People's Republic of China. It is the largest river in Fujian, and an important water transport channel. Most of northern and central Fujian is within its drainage area. The provincial capital, Fuzhou, sits on the lower Min River, with its historic center being on the northern side of the river, even closer to its fall into the East China Sea; the location historically made it an important port. Alternate sources The traditional source of the Min River is in the far northwest of the basin, hence in China the highest reach is called the Beixi Brook. The total length of the river using this source is 505 km. But in fact, the Beixi is neither the geographic or hydrological source of the river. The Shuiqian is the furthest geographic source, and the Shuiqian-Shaxi-Min is 580 km long. A different river, the Jin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zipingpu
Zipingpu Dam (紫坪铺水利枢纽) is an embankment dam on the Min River near the city of Dujiangyan, Sichuan Province in southwest China. It consists of four generators with a total generating capacity of 760 MW. Construction began in 2001 and was finished late 2006. The dam site was originally developed during the Shu-Han nearly 2000 years ago. The traditional Dujiangyan Irrigation System consisting of canals, levees, and dams, has been in use since 256 BC. Controversy The 7.9 magnitude quake on May 12, 2008 caused some damage to the dam, with its wall being cracked and fissured. The reservoir had to be gradually drained to permit consolidation works. The reservoir is located just a few kilometers from the 2008 earthquake epicenter, and just a few hundred meters from the fault. Some geologists hypothesized that the loading and unloading of the crust below the reservoir caused by changes in the water level may have somehow acted as a trigger to the earthquake. However ...

Hydroelectric
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Joseph Needham
Noel Joseph Terence Montgomery Needham (; 9 December 1900 – 24 March 1995) was a British biochemist, historian of science and sinologist known for his scientific research and writing on the history of Chinese science and technology, initiating publication of the multivolume ''Science and Civilisation in China''. He was elected a fellow of the Royal Society in 1941 and a fellow of the British Academy in 1971. In 1992, Queen Elizabeth II conferred on him the Companionship of Honour, and the Royal Society noted he was the only living person to hold these three titles. Early life Needham's father, Joseph was a doctor, and his mother, Alicia Adelaïde, née Montgomery (1863–1945), was a music composer from Oldcastle, County Meath, Ireland. His father, born in East London, then a poor section of town, rose to became a Harley Street physician, but frequently battled with Needham's mother. The young Needham often mediated. In his early teens, he was taken to hear the Sun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Li Bing (Qin)
Li Bing (; ) was a Chinese hydraulic engineer and politician of the Warring States period. He served the Qin (state), state of Qin as an administrator and is revered for his work on the Dujiangyan Irrigation System, Dujiangyan River Control System, which both controlled flooding and provided irrigation water year-round, greatly increasing the productivity of the valley. Li Bing became a cultural icon, known as the vanquisher of the Water deity, River God and is compared to the Great Yu. Dujiangyan is still in use today and is listed as a UNESCO World Heritage Site. Life and career King Zhaoxiang of Qin (r. 306–251 BC) dispatched Li Bing as a joint military and civilian governor (''shou'') over Shu (state), Shu, a recently defeated state in Sichuan province, Southwest China, just west of modern Chengdu. According to the ''Records of the Grand Historian'', Li Bing was appointed governor of Shu in c. 277 BC. However, the ''Chronicles of Huayang'' place Li Bing in Shu in 272 ...

Sichuan Taimen
''Hucho bleekeri'', the Sichuan taimen, is a species of freshwater fish in the salmon family (Salmonidae), endemic to the Yangtze basin in China. Their typical habitat includes mountain streams and small rivers, typically being found in the catchment areas of the Dadu River in Sichuan and Qinghai Provinces, as well as the Hanjiang River. This particular fish population is largely threatened by habitat loss and illegal fishing, resulting in a " critically endangered" conservation status from the International Union for Conservation of Nature. Appearance The vertebrates have a dark Gray back, silvery white underside, and small cross-shaped spots across the body and gill cover. Adults can grow up to in length.Song, Z. 2012''Hucho bleekeri'' In: IUCN Red List of Threatened Species. Version 2012.2. . Downloaded on 26 October 2012.

Fish
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Mos ...
