Who has a research report on the development and environmental evolution of the Three Gorges Valley

After the completion of the Three Gorges Dam, it will form a huge reservoir with a length of 600 kilometers, which will become a rare new landscape in the world. The Three Gorges Dam stores water in stages. After the damming of the river on November 8, 1997, the water level was raised to 10 75 meters, and all the landscape of the Three Gorges was not affected. In June 2003, after the end of the second phase of the project, the water level was raised to 135 meters, and the Three Gorges Tourist Scenic Area was basically preserved except for the flooded Zhang Fei Temple, which will be relocated; In 2006, the water level of the Yangtze River was raised to 156 meters, and only the mountain gate of Qu Yuan Temple was flooded and will be rebuilt; After the completion of the Three Gorges Project in 2009, the water level will be raised to 175 meters, when there will be a few stone carvings will be relocated, the mountain gate of Shibaozhai will be flooded, and it is currently planned to build a dam to enclose it, when Shibaozhai is located Yuyin Mountain will become a lone peak surrounded by water on all sides, more chic and legendary.

The majesty of the other attractions remains the same. With the formation of man-made lakes and the improvement of navigation conditions among the mountains along the river, many scenic spots originally scattered around the Three Gorges will be easier to reach, such as the Little Three Gorges, Shennong Creek and other wonderland galleries.

Unit 20 of the Right Bank Power Station of the Three Gorges Project was officially put into operation a few days ago, and the installation and construction unit China Gezhouba Group Corporation handed over the operation and management of the Three Gorges Power Plant, which is the 20th giant unit of the Three Gorges Power Station officially put into operation. So far, the capacity of the Three Gorges Power Station has reached 14.1 million kilowatts, and the installed capacity of hydropower has jumped to the first place in the world.

Unit 20 is also the sixth 700,000 kW unit of the Three Gorges Right Bank Power Station to be put into operation. Previously, the Three Gorges Power Station has put into operation 19 giant units, including 14 on the left bank, plus the Three Gorges Power Station has been put into operation with an installed capacity of 50,000 kilowatts of small units 2, the Three Gorges Project has been put into operation with an installed capacity of 14.1 million kilowatts, higher than the 12.6 million kilowatts installed capacity of the Itaipu Power Station in Brazil.

A total of 32 700,000-kilowatt hydro-generating units are planned to be installed in the Three Gorges Project, which is the largest hydropower unit in the world today. As of December 20, the Three Gorges Power Station has generated more than 206 billion kilowatt hours of electricity.

Fengjie County, Chongqing, not Sichuan. Chongqing was separated from Sichuan in 1997, and Fengjie is under the jurisdiction of Chongqing. It's really hard for you people, 5 points can make you people find 1997 on the Internet.

I'm not trying to argue about anything, I'm trying to help you revise it.

The Three Gorges of the Yangtze River is located in the hinterland of China and is the general name of the three gorges of Qutang Gorge, Wu Gorge and Xiling Gorge. It is 193 kilometers long from Baidi City in Fengjie County, Chongqing City in the west, to Nanjin Pass in Yichang City, Hubei Province, across Fengjie County, Chongqing Wushan County, Hubei Badong County, Hubei Zigui County, and Hubei Yichang City. It is often referred to as the "Great Three Gorges".

The Yangtze River, the main body is Dayu when the water control, manually dug out!

This is recorded in "Yu Gong":

Yu farewell Kyushu, with the mountains and rivers, let the soil as tribute. Yu covers the soil, with the mountains and wood, laying high mountains and rivers. ”

The ridge mound guides the Yang, the east flows for the Han, and the east, for the water of the waves, crosses the three rivers, as for the big bie, the south enters the river. In the east, Huize is Peng Li, and in the east, it is the Beijiang River, which enters the sea. "— This is the Han River being dredged.

The Jiang and Han dynasties are in the sea" - this is the meaning of the Yangtze River and the Han River being dredged and flowing to the sea.

You can use Google Earth to see the landform of the Three Gorges of the Yangtze River, which is full of traces of artificial digging. This includes, but is not limited to:

The coherent mountains were dug into breaches

The slopes on both sides of the bank are split into cliffs

The mountain valleys were dug deep into large rivers

The high mountains and flatlands were dug up and crushed into chaotic peaks

All the landforms marked by the white circles in the map are hand-dug imprints, and the scope is extremely wide, and only a few maps are pasted here. If you are interested, observe it yourself, but don't use books to understand these landforms. Those who answer the question of plate movements eons ago and so on are people who endorse rather than think about themselves in practice.

Don't doubt the following words:

Ancient mythology is the history of the ancient period of human civilization. In ancient times, man and god lived together, and the gods, the races of higher technological civilizations, and people, were the products of God's genetic engineering, and God created man, and Nuwa created man as different versions of the same event.

The era of Dayu is a civilization several levels higher than modern scientific and technological civilization, and the machine used is a giant excavator that is many times larger than a modern large aircraft carrier.

The coherent mountains were dug into cliffs.

The coherent mountains were dug into cliffs.

The splitting surface is dug up in distortion with the terrain structure.

Prismatic chisel imprints.

The Three Gorges waterway of the Yangtze River is full of artificial cliffs and cutting surfaces.

The formation of the Three Gorges of the Yangtze River.

The formation of the Three Gorges is the result of land and sea changes and the development of rivers caused by strong orogeny. During the Triassic period, 200 million years ago, China's topography was the opposite of today, high in the east and low in the west. The western part of today's Yangtze River basin is the ancient Mediterranean.

The area around the Three Gorges is the seashore at that time. During the orogeny at the end of the Triassic, the crust of the coast here rose, the ancient Mediterranean Sea retreated westward on a large scale, and the now famous Huangling anticline began to take shape at sea level. In its west and east, the prototype of the eastern and western ancient Yangtze River appeared, respectively.

In another orogeny about 70 million years ago, the Sichuan Basin and the Three Gorges region were uplifted, and the thick rocks in the Three Gorges area were squeezed into twisted folds and faults. Today's Qiyao, Wushan, and Huangling in the Three Gorges area are the three sections of mountain anticlines formed during this orogeny. After the uplift of these three anticlines, the rivers developed on the east and west slopes formed opposite flow directions.

By the time of the Himalayan orogeny 30 to 40 million years ago, the ground in the Yangtze River basin generally rose intermittently, so the terrain was high in the west and low in the east. Until now, the earth's crust in the Three Gorges region is still slowly rising. After the uplift of the Three Gorges anticline, the rivers on both sides of it, namely the ancient Yangtze River in the west and the ancient Yangtze River in the east, are close to each other in the downward cutting and traceability erosion of the rivers.

Because China has formed a high topography in the west and low in the east at this time, the rivers on the eastern slope are steeper than those on the western slope, and their traceability erosion ability is also stronger than that on the western slope. After tens of millions of years of cutting, the three anticlines in the Three Gorges area were finally cut through, so the two ancient Yangtze rivers in the east and west were connected into one gas, forming today's Yangtze River.

After the formation of the Three Gorges, the cutting and eroding effect of the river water on the riverbed and both banks became more intense, which deepened the riverbed. This development is still ongoing.

The Three Gorges of the Yangtze River is one of the largest canyons in the world, famous for its magnificent natural scenery of rivers and mountains. It starts from the White Emperor City of Fengjie County, Chongqing in the west, and reaches the Nanjin Pass of Yichang in Hubei Province in the east, with a total length of 204 kilometers, the cliffs on both sides of the river, the beach and gorge in the river are interspersed, the water flow is turbulent, the mountain peak is showy, the wall is steep and the gorge is narrow, the canyon scenery of the water meandering loop, 'the mountain is suspicious and there is no road, there is no sky between the bays' feeling is really good, the great poet Li Bai of the Tang Dynasty left a beautiful poem after passing here: "The white emperor of the dynasty is between the clouds, and the thousands of miles of Jiangling are returned in one day; The apes on both sides of the strait could not stop crying, and the light boat had already crossed the Ten Thousand Mountains."

After four years of research, the research group of "Research on the Development and Environmental Evolution of the Three Gorges Valley of the Yangtze River" led by Yuan Daoxian, an academician of the Chinese Academy of Sciences and a professor at Southwest University, has recently established a complete chronological sequence of the Yangtze River terraces in the Three Gorges area for the first time, and officially revealed that the formation time of the Three Gorges of the Yangtze River was 2 million years ago. On the basis of a large number of field investigations, the theories and methods of geology, geography, hydrology and soil science were comprehensively applied to systematically collect samples from 12 key work sections, and a large number of experimental samples were studied through a variety of technical means, and the distribution, characteristics, age and genesis and environmental significance of "Jiangbei conglomerate" in the Three Gorges area were preliminarily clarified. Through research, the research team proposed that the Yangtze River had passed through the Three Gorges area 2 million years ago, when the area was dominated by wide valleys and hilly terrain, and then due to tectonic uplift, the river was strongly cut down to form a canyon topography. ]

This river called the "Yangtze River" has existed for a long, long time.

Chongqing, Dec. 2 (Xinhua) -- A study organized by the Chongqing Municipal Science and Technology Commission shows that the Yangtze River was formed 2 million years ago, the Yangtze River flows eastward due to the uplift of the Qinghai-Tibet Plateau, and the connection of the Three Gorges section is a major geological event in the history of the Yangtze River's evolution.

In 2005, the Chongqing Municipal Science and Technology Commission launched the implementation of the academician special project to support Academician Yuan Daoxian of Southwest University to carry out the "Research on the Development and Environmental Evolution of the Three Gorges Valley of the Yangtze River". After two years of hard work, the researchers established the first complete chronological sequence of the Yangtze River terraces in the Three Gorges area, put forward a new understanding of the geological period of the Three Gorges area, and elucidated the development process of the Three Gorges Valley.

The research results will greatly promote the research on the development and evolution of the Three Gorges Valley of the Yangtze River, and provide important theoretical basis and practical guidance for environmental protection and planning in the Three Gorges Reservoir area. The historical conclusions on the evolution of regional karst landforms put forward by the research results provide important technical support for the successful application of Wulong karst landform as "World Natural Heritage".

The Three Gorges of the Yangtze River refers to the Qutang Gorge, Wu Gorge and Xiling Gorge between Chongqing Municipality and Hubei Province.

The Three Gorges of the Yangtze River stretches from Fengjie County in Chongqing Municipality in the west to Yichang City in Hubei Province in the east, with a total length of 193 kilometers. From west to east, there are three main canyon sections: Qutang Gorge, Wu Gorge and Xiling Gorge, hence the name of the Three Gorges.

The high mountains on both sides of the Three Gorges face each other, the cliffs are steep, and the peaks are generally 1,000---1,500 meters above the river surface. The narrowest point is less than 100 meters. The Three Gorges was formed due to the rising crust of the Yangtze River in this area, so it is extremely rich in hydraulic resources.

Qutang Gorge, Wu Gorge and Xiling Gorge.

1. Qutang Gorge:

From the White Emperor City of Fengjie County in the west, to Daxi Town of Wushan County in the east, the total length is 8 kilometers, and the scenery is the most majestic and precipitous. The main attractions are Fengjie Ancient City, Eight Array Map, Yufu Tower, Ancient Plank Road, Bellows Gorge, Powder Wall Wall, Mengliang Ladder, and Rhino Moon Looking.

In the Three Gorges of the Yangtze River, although it is the shortest, it is the most majestic and steep.

2. Wuxia: From the Daning River estuary in the east of Wushan County, Chongqing City, to the Guandu Port of Badong County, Hubei Province in the east, stretching for more than 40 kilometers, including Jinlanyinjia Gorge and Iron Coffin Gorge, the canyon is particularly deep and tortuous, and is formed by the Yangtze River cross-cutting the main vein of Wushan anticline.

It is also known as the Great Gorge and is known for its deep and beautiful scenery. The strange peaks of the whole gorge area are abrupt, the strange rocks are craggy, the cliffs are lined up, and they are continuous, and it is the most considerable section of the Three Gorges. Wuxia Gorge is long and deep, the strange peaks are continuous, the smoke and clouds are swirling, the scenery is extremely quiet, like a beautiful gallery with twists and turns, full of poetry and calligraphy.

3. Xiling Gorge:

From Xiangxikou in the west, to Nanjin Pass in the east, it is famous for its tortuous waterways, strange rocks, many beaches and rapids, and thrilling boats in history.

After the founding of the People's Republic of China, after years of management of the Sichuan River waterway and the completion of the Gezhouba water conservancy project, the water potential has tended to be flattened, but the beautiful landscape is still the same.

The formation of the Three Gorges.

Recently, the research group of "Research on the Development and Environmental Evolution of the Three Gorges Valley of the Yangtze River" led by Yuan Daoxian, an academician of the Chinese Academy of Sciences and a professor at Southwest University, has recently made a major breakthrough after four years of research, establishing a complete chronological sequence of the Yangtze River terraces in the Three Gorges area for the first time, and identifying that the Three Gorges of the Yangtze River was formed 2 million years ago. The study points out that the eastward flow of the Yangtze River is due to the uplift of the Qinghai-Tibet Plateau, and the connection of the Three Gorges section is a major geological event in the evolutionary history of the Yangtze River.

The research focus of this project is on the geomorphological evolution of the Three Gorges area and the genesis of the special deposited "Jiangbei conglomerate". On the basis of a large number of field investigations, the research group carried out tests on pollen, heavy ore assemblage, magnetic susceptibility and other tests on a large number of experimental samples, applied geology, geography, chronology and other tests, and comprehensively applied geology and other theories and methods to study the valley landform and various accumulations in the area, and preliminarily clarified the distribution, characteristics, age and genesis and environmental significance of "Jiangbei conglomerate" in the Three Gorges area, and established a complete chronological sequence of the Yangtze River terraces in the Three Gorges area for the first time.

From the White Emperor City in the west to Nanjin Pass in the east. It is the general name of the valley of Wuxia, Qutang Gorge and Xiling Gorge The total length is 204 kilometers, and it is the most beautiful and magnificent landscape gallery on the Changsui River.
