Yangtze RiverDuring the 40 million of years history of the life and 50,000 years of human civilization, Yangtze River, a mother of the Chinese people, bring up billions of Huaxia people.Different from the Missippi, the Niro and the Amason, Yangtze River is the largest river in China, rising from Qianghai Highland at the height over 3,000 meters, running through Mt.Wu covering with frog, absorbing thousands of rivers, traveling 6,400 km until it reach the Pacific. She passes by mountains, gorges, hills, plains, with changing scenes on different geographic shape. She lies on the mil-latitude area, the four seasons are distinctive here. The huge flow reaches 97,935 billons cubic meter and ships can sail in the lower reaches all the year.The drainage area is over 1.8 million km, being 19% of the total cultivable land in the country. Here, the weather resource and the total productive value of the industry and the agriculture area 40% of the total respective in the country, bringing up about 400 millions persons, 1/3 of the population in China.It was 100,000 years ago that the human beings have lived in the Yangtze drainage area. Lantian man, Changyang man, Yunxian man are all the Chinese remote ancestors. And the ancient human remains and ruins of the Old and New stone Ages have been discovered everywhere along the river nowadays. 7000 years ago, our ancestors were fishing, cultivating, planting rice and bringing up descendants here. When it was in civilized society. Varies of distinctive national features were born here. Such as Jingchu Culture, Wu and Yue Culture, Bashu Cultures. The are all the priceless treasure in Chinese traditional cultures.A place with mountains and rivers is always thought to be a precious land. Water is the reflection of the intelligence and the beauty. The living of the human being exist without water, the industry and the agriculture can’t leave water anyway also. Before trains, airplanes anf automobiles were invited, the waterway afforded the facilities on transport and the ship was the important traffic instrument. The water can bring people intelligence and enlighten people soul. Laozi and Zhuangchou got thoughts from mountains and rivers, who were both the citizens of the ancient Chu in South, developed Neo-confucianism and Taoism respectively. Many literary works, poem, dances, music, concerning to Yangtze Rive have been unique works of China and even on the world. For example, “Flowing down the high mountain” by Zhong Ziqi in the War Ages has become a world-famous classical melody today.In the ancient time, the people lived accommodating water source passively. As the saying, the water that bearing the boat is the same swallows it, Yangtze River benefits the human beings while brings flood. Most flood were took place in the Yangtze River area in the ancient time. On the other hand, the disasters have given Yangtze people a lot of experience fighting against the flood and a national characteristics showing a strong will of never giving up.After the human being entered into civilized society, wars, famines have taken palace here, aggressors’ tombs being remained for several thousands of years, the peaceful history with scenes of mature rice field extending thousands miles. As well as sad scene of desolation and being full of hungry people have shown up here. Today, along the Yangtze River from the birthplace Qianghai to the enterance on the pacific in shanghai, hundreds of largest –and –medium –size vigorous cities are the faster developing areas in China. As well as unsophisticated farmers with out –of –date production methods and transport instruments there are also modern metropolises changing everyday. The new-borned phenomena accompany with the conservation, the civilization exists with the backwardness.Yangtze River ,the great mother river, is going on bring up her people full of hopes and energy. Yangtze River is the symbol of China opening outside. Chinese rapid development of economy is just the rippling waves of the River flowing foreward.Yangtze River is a magic beautiful river, the changing scenes, unsophisticated characteristics, like a painted corridor filled with historic legends, should give you a marvelous experience.Maybe you have read a book about China and Yangtze River, but remember the saying “Hearing about for a hundred times is far less than seeing once.” everyone will experience different from others in different time and conditions.Only next to Yangtze River in yellow river, is China the second river, fuck to flow all long 5,464 kilometers of, flow through Qing Lake, Szechwan, gansu, Ningxia, Suiyuan, the west of shanxi , mountain west, river south and Shandong nine provinces," several" form, infuse into to east Bohai Sea, the along the road gathered together a main subsidiary current with the numerous river sichuan , the river valley area amounts to more than 750,000 square kilometers.Visit inside a the segment flows through the large loess plateau region, many subsidiary currents clips to take the sediment of large quantity remits, for in the world river with sand measures at most, the river water reports yellow, as a result get. On the history, the yellow river flows the city to usually become disaster.According to jot down, more than 2,000 in the last years, the yellow river downstream 溃 dike amount to 1,500 many, than change large-scalely the way have 26 times, flood disaster scope north to Tienjin, the south reaches Jiangsu, Anhui, amounting to 250,000 square kilometers widely.The river water clips the sediment gross that take to the downstream measures, average annually over 1,600,000,000 metric tons.Because the downstream a geography is low and even, the course of river declines the even , the current velocity turns down, the sediment of large quantity hence sink to accumulate on the river bed, average every year overs 400,000,000 metric tons of, the rest sediment then flows the river mouth, forming a delta toward river mouth delta that sea stretch, average build annually six amount to more than 20 square kilometers.Yellow river river valley contain fatty and original fertile fields, the products is abundant, the mountain and stream is magnificent, the resident is several to occupy the Chinese total population quarter, the farmland then invites to occupy national 40%.

The Yellow River or Huang He / Hwang Ho is the second-longest river in China and the sixth-longest in the world at 5,464 kilometers .Originating in the Bayan Har Mountains in Qinghai Province in western China, it flows through nine provinces of China and empties into the Bohai Sea. The Yellow River basin has an east-west extent of 1900 km and a north-south extent of 1100 km .Total basin area is 742,443 km².The Yellow River is called "the cradle of Chinese civilization", as its basin is the birthplace of the northern Chinese civilizations and was the most prosperous region in early Chinese history. But frequent devastating flooding largely due to the elevated river bed in its lower course, has also earned it the unenviable name "China's Sorrow".Early Chinese literature refers to the Yellow River simply as He (河), the word that has come to mean simply "river" in modern language .The first appearance of the name "Yellow River" (黄河) is in the Book of Han (Chinese: 汉书;) written in the Western Han dynasty (206 BC–AD 9). The name "Yellow River" describes the perennial ochre-yellow colour of the muddy water in the lower course of the river. The yellow color comes from loess suspended in the water.Sometimes the Yellow River is poetically called the "Muddy Flow" (simplified Chinese: 浊流). The Chinese idiom "when the Yellow River flows clear" is used to refer to an event that will never happen and is similar to the English expression "when pigs fly".CharacteristicsThe 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. If it is running to the sea with sufficient volume, 1.4 billion tons are carried to the sea annually.In modern times, since 1972 when it first dried up, the river has dried up in its lower reaches many times, from Jinan to the sea in most years, in 1997 for 226 days. The low volume is due to increased agricultural irrigation, by a factor of five since 1950. Water diverted from the river as of 1999 served 140 million people and irrigated 74,000 km² of land. The highest volume occurs during the rainy season, from July to October, when 60% of the annual volume of the river flows. Maximum demand for irrigation is needed between March and June. In order to capture excess water for use when needed, and for flood control and electricity generation, several dams have been built, but due to the high silt load their life is expected to be limited. A proposed South-North Water Transfer Project involves several schemes to divert water from the Yangtze River, one in the western headwaters of the rivers where they are closest to one another, another from the upper reaches of the Han River, and a third using the route of the Grand Canal.Due to its heavy load of silt the Yellow River is a depositing stream, that is, it deposits part of its carried burden of soil in its bed in stretches where it is flowing slowly. These deposits elevate the riverbed which flows between natural levees in its lower reaches. Should a flood occur, the river may break out of the levees into the surrounding lower flood plain and adopt a new course. Historically this has occurred about once every hundred years. In modern times, considerable effort has been made to strengthen levees and control floods.The Yellow River delta totals 8,000 square kilometers .However, since 1996 it has been reported to be shrinking slightly each year through erosion.

Yellow river originates the Qinghai-Tibet Plateau Bayankalashan northern altitude of about 4500 meters out in the ancient basin. The Qinghai-Tibet Plateau in Qinghai, Sichuan, Gansu, Ningxia highland loess plateau and Plateau, Inner Mongolia, Shaanxi, Shanxi, North China plain of Henan, Shandong, inject Bohai that stands 5,464 km, covers 750,000 square kilometres.Yellow River flows through the loess plateau because, with a lot of sand, the average years amounted to 1.6 billion tons of sand and rocks to the earth embankment 1 meter square circle around the Earth 27. Annual siltation in the downstream river bed has 400 million tons of mud to higher ground more than 10 metres into the Yellow River "hanging river." Located in middle reaches of the monsoon climate zone, precipitation variability, big and more rainstorms. Yellow River floods caused by torrential rains and mud downstream river bed of good blocking, good will, good disciple. From the introduction to the 2500 years of 1949, the Yellow River downstream must Yat 1590, diverted 26. Yellow River and the Yellow River water spiritual nurturing of the Chinese nation. Yellow River basin in the ancient Chinese nation and staging magnificent brilliant drama, the children of ex returns Mother River. Annual Chinese nation must bridge Hill Yellow Emperor mausoleum After the memorial in Shaanxi, Shanxi annually to countless people should discharge of large locust tree roots. Yellow River civilization with its great cohesion and creativity, leading the Chinese people as long Yellow River flow perseveringly surging, toward a better future.
