Urgent! ! ! What major landslides have occurred in the Three Gorges reservoir area since 2006?

On April 20th, foreign media reported that 20,000 people living near the Three Gorges Dam will be relocated in China before the end of this year, and about 654.38 million people will be relocated in the next few years, because the world's largest hydropower project has caused the danger of landslide.

Reuters quoted China's official media as saying that preparations for moving one-fifth of the residents in Badong County, Hubei Province by the end of 20 12 have begun, and the houses here have been threatened by "multiple landslides".

According to the The New York Times website, Liu Yuan, an official of the Ministry of Land and Resources of China, told China National Radio that the rising water level of the Three Gorges Reservoir made the nearby ground more and more unstable. Since 20 10 reservoir reached the highest water level, more than 70% of the geological disasters in the reservoir area are sudden geological disasters. Liu Yuan said that officials have recorded 430 landslides and nearly 2,900 minor geological accidents around the reservoir, and are monitoring 5,386 other potentially dangerous sites.

The report pointed out that serious landslides will not only endanger people living along the coast, but also produce dangerous waves. In 2003, there was a landslide, which produced waves of 20 meters high, causing 14 deaths.

Since the reservoir began to fill, officials have tried various water levels, from 135 meters to the highest recommended water level 175 meters. With the increase of water level, geological accidents become more frequent. Liu Yuan said that landslides are expected to occur within three to five years after the reservoir reaches the highest water level.

According to an article on the investigation of the Three Gorges Dam in Scientific American magazine in 2008, part of the reason for the landslide is that the government raises and lowers the water level seasonally to cope with the flood.

The Three Gorges Dam is the largest hydropower project in the world. In order to make way for this dam, which was completed in 2006 and has a height of185m, and the reservoir, which stretches for more than 600km and reaches the highest water level of175m in 20 100, about 654,380+040,000 people were initially resettled. As early as 2003, the reservoir was criticized by environmentalists and some geologists before it began to flood a large basin of the Yangtze River. In 2007, the government admitted that the rising water level caused instability, and if preventive measures were not taken, disaster might occur.

According to official figures, the cost of the Three Gorges hydropower project has risen sharply in recent years, with a total investment of 254 billion yuan. The Three Gorges Project Construction Committee previously stated that the follow-up project will cost 654.38+0238 billion yuan.

The largest landslide in the Three Gorges reservoir area is planned to relocate nearly 20,000 people during the year.

Xinhua News Agency, Yichang, April 18 (Reporter Liu Ziling, Feng Guodong) The reporter learned in an interview with Badong County, Hubei Province, a big resettlement county in the Three Gorges reservoir area on April 18 that the residents' relocation of Huangtupo, the largest landslide in the Three Gorges reservoir area, is proceeding in an orderly manner, and it is planned to relocate nearly 20,000 people during the year.

Huangtupo is located in Badong County, with a total area of 6.5438+0.35 million square meters and a total volume of 69.34 million cubic meters, involving a total population of nearly 20,000 people, accounting for more than 65.438+0/5 of the whole Badong County, and the landslide scale ranks first among the geological landslides in the Three Gorges reservoir area.

Zhao Wenxing, chief of the comprehensive department of the integrated evacuation headquarters of Huangtupo landslide, said that from the planning and design of resettlement in the reservoir area of the Three Gorges Project 1992, the relevant state departments identified the Huangtupo area as a huge deep ancient landslide accumulation body through exploration and demonstration. Later, many landslides and collapses caused casualties, which attracted great attention from the central authorities and relevant parties and decided to evacuate the units and households on the landslide as a whole.

The reporter saw at the scene of 18 that there are many shops along Huangtupo Street, many of which are still open. At noon, many citizens still buy food on the roadside. Because of the continuous landslide, the floor tiles of Zhao Yuehui's house have shifted and broken, and the government built a new house for him at the resettlement site on the other side of the Yangtze River. However, Zhao Yuehui said that he was not in a hurry to move and wanted to wait until the supporting facilities in the new community were perfect.

It is understood that up to now, the 550 million yuan of funds approved by the state for overall hedging and relocation have been allocated and fully used. Families in the most dangerous areas and crowded places such as schools and hospitals have been relocated. In accordance with the principle of "moving one and demolishing one", the local authorities have simultaneously promoted the demolition of buildings (structures) on the Huangtupo landslide, and 70,000 square meters of houses have been demolished.
