Is the Three Gorges Dam beneficial or harmful? The advantages of the Three Gorges Dam outweigh the disadvantages.

Three Gorges dam:

The Three Gorges consists of Qutang Gorge, Wuxia Gorge and Xiling Gorge. The Three Gorges Hydropower Station, also known as the Three Gorges Project and the Three Gorges Dam. Located on the main stream of the Yangtze River between Chongqing City in China and Yichang City in Hubei Province. The dam is located in Sandouping, not far upstream of Yichang City, and forms a cascade hydropower station with Gezhouba Hydropower Station downstream. It is the largest hydropower station in the world and the largest construction project in China.

Benefits:

Can withstand the once-in-a-century flood.

The economic benefits of the Three Gorges Project are mainly reflected in power generation.

Improve the shipping conditions of the middle and lower reaches of the Yangtze River in dry season.

Disadvantages:

expensive

environmental damage

population migration

The construction of the Three Gorges Project is a national event. Since its fruits are enjoyed by the whole people, its costs should also be borne by the whole people.

Advantages and disadvantages of the Three Gorges Dam: flood control, power generation and shipping.

Disadvantages: induced earthquake, climate change, siltation, military security.

Advantages and disadvantages of the Three Gorges Dam;

1. can resist the once-in-a-century flood.

2. At that time, you can generate electricity for half of China!

3. Highlight the outstanding architectural level of China since ancient times!

Disadvantages:

1. It costs a lot.

2. If it is destroyed, the consequences will be unimaginable.

3. The famous places of interest are all submerged!

4. A large number of people were forced to evacuate!

Disadvantages of the Three Gorges Dam: ecological destruction, and immigration wastes people and money. The reservoir can regulate the local climate, but it will not show up in five or six years, and its changing direction is not clear, but the overall impact is not great. In addition, the reservoir is silted up, but the current situation is much better than when it was designed. Landslides on both sides of the strait need a lot of manpower, material resources and financial resources to control.

Advantages and disadvantages of the Three Gorges Dam The benefits of the Three Gorges Project mainly focus on flood control, power generation and shipping.

The Three Gorges Project can effectively prevent and control floods. China is a typical southeast monsoon climate with uneven rainfall distribution. The Yangtze River is also an aboveground river from Yibin to Wuhan. In the past two thousand years, there has been a flood in less than ten years, and the flood of 1998 is still fresh in everyone's memory. After the completion of the Three Gorges Project, the huge adjustment of reservoir capacity can effectively improve the downstream flood control standards and effectively delay river siltation. The first thing is flood control, which is a very necessary measure for people to live in harmony with nature. The plain in the middle and lower reaches of the Yangtze River is the essence of industry and agriculture in China. But the ground is generally 6- 17 meters lower than the flood, and it is protected by dikes with a total length of more than 33,000 kilometers. The ancient floods in the Yangtze River were frequent to about 10 years, and the floods were powerful. After the completion of the Three Gorges Dam, the once-in-a-century flood can be controlled to ensure the safety of the middle and lower reaches. In case of a once-in-a-thousand-year flood, the danger of dam break can be avoided through flood diversion and cooperation of flood diversion. History will prove that the Three Gorges Project of the Yangtze River is the patron saint of directly ensuring the safety of nearly 23 million mu of cultivated land,150,000 people's lives and property and the safety of the main arteries of Beijing-Guangzhou and Beijing-Kowloon railways in the flood control system in the middle and lower reaches. The history of China is the history of river management. If the flood is not cured, the country will not be stable. In other words, without the Three Gorges Project, other aspects of the Three Gorges Project can still be replaced when it is demonstrated, but flood control is irreplaceable. If the Three Gorges Project Department is built, we have no effective means in flood control, and people and nature in Jianghan area cannot live in harmony.

After the completion of the Three Gorges Dam, the surging river will do work and generate electricity for the Three Gorges Hydropower Station, reversely adjust the navigation steps between the Three Gorges and Gezhouba, and then do work and generate electricity for the Gezhouba Hydropower Station, so that the total annual power generation of the Three Gorges and Gezhouba will reach/kloc-0.05 billion kWh. If the electricity price per kwh is 0. 1 yuan, the annual innovation value is 105 billion yuan; If the output value of each kilowatt hour is 5 yuan, it can increase the output value of the country by 525 billion yuan every year; The per capita annual output value is 6,543,800 yuan, and 5.25 million people can be employed. Located in the hinterland of China, the Three Gorges Hydropower Station is about 1000 km away from the main load center in China, and will be the main power grid interconnection center in the future. After the power grid is connected, it can not only complement the national fire, water and nuclear power, but also greatly improve the quality and efficiency of power grid implementation. Therefore, the Three Gorges Hydropower Station will be the future power dispatching center of China.

The construction of the Three Gorges Project is a golden opportunity for the reservoir area with inconvenient transportation and relatively backward economic development. The 660-kilometer-long Yiyu River is very poor. There are more than 100 beach risks, dozens of single-voyage sections and dozens of overloaded cargo ships that need to be towed. The annual one-way shipping capacity is insufficient100000 tons. After the completion of the Three Gorges Dam, all beach hazards, single navigation sections and towing sections will be submerged, and the navigation channels will be widened a lot. When the 10,000-ton fleet reaches the sea through inland rivers, the shipping cost will be greatly reduced, and the annual one-way shipping capacity will exceed 50 million tons. Then, the formation of the golden waterway across China, the east and the west is very beneficial to the economic development and prosperity from both sides of the Yangtze River to the coastal areas.

In addition, the Three Gorges Project is also of great benefit to the environment, the South-to-North Water Transfer Project and aquaculture.

But a decision takes so long, and the influencing factors cannot be ignored. The construction of the Three Gorges Project is mainly hindered by cultural relics protection, ecological protection and large-scale migration.

It has been proved that there are a large number of cultural relics buried in the Three Gorges area, many of which are extremely precious and have not been discovered so far. However, it is impossible to have enough time to dig up these precious cultural relics from the start of the Three Gorges Project to the impoundment. According to reports, only one tenth of all cultural relics have been really excavated, which means that 90% of precious cultural relics are buried at the bottom of the river. This is a very sad thing. There are also some places of interest along the Three Gorges, such as Zhangfei Temple, which have to be submerged in the river. This is a great damage to the history and culture of China.

In terms of ecology, the construction of the Three Gorges Project will have an impact on the local large-scale ecology, such as the destruction of local vegetation and climate change, which will have a great impact on all kinds of animals and plants. According to related reports, due to the construction of the Three Gorges Project, the climate nearby is abnormal, but it is still very cold when it is warm. There are also a lot of landslides in some places, which are estimated to be related to the Three Gorges Project. Some organisms, such as fish, have changed their living environment because of water storage and other reasons, which has an impact on reproduction.

And mass migration. People who once lived in the Three Gorges area had to give up the place where they lived for generations and go to a new environment. The social problems brought by immigration, such as how and where immigrants are resettled, can not be ignored.

Every public policy decision was made based on the theory at that time, but the actual effect was not accurately predicted at that time. The actual good or bad may be an evaluation of the right or wrong of this decision. The Three Gorges Project has been under construction for more than ten years. Judging from the current situation, the disadvantages of the Three Gorges Project are relatively few, and its benefits are gradually emerging. Practice has proved that the original decision was reasonable and scientific. I hope that in the future, this conclusion is still correct. The Three Gorges Project will bring us more and more benefits and promote economic development, social prosperity and national prosperity.

In short, the benefits are flood control, power generation, improved shipping, improved environment, South-to-North Water Transfer Project and aquaculture.

The disadvantage is that it destroys cultural relics and affects the ecological environment. The advantages of resettlement are: sightseeing, flood control, power generation, water storage and freshwater aquaculture ... Disadvantages: a large area of land is flooded, many cultural relics are not protected, and residents have to move; The downstream water volume is reduced, the self-purification ability is weakened and the pollution is aggravated; Sediment reduction, seawater erosion (many, controversial)

What are the advantages and disadvantages of the Three Gorges Dam in China? Benefits:

In terms of flood control, the rainfall distribution in the southeast monsoon climate is very uniform. The construction of the Three Gorges Project effectively improved the downstream flood control standard, and also effectively delayed the siltation of the Three Gorges Project on the Yangtze River, which directly guaranteed the life and property safety of nearly 23 million mu of cultivated land and150,000 people in the downstream flood control system, as well as the power supply of the main arteries of the Beijing-Guangzhou and Beijing-Kowloon railways.

The total power generation is/kloc-0.05 billion kwh, which is located within the transmission distance of/kloc-0.000 km from the hinterland of China to major load centers in China. Develop and prosper the economy from both sides of the Yangtze River to the coastal areas. In addition, the Three Gorges Project will also greatly benefit the environment, the South-to-North Water Transfer Project and aquaculture.

Disadvantages:

Although the Three Gorges Dam claims to generate a lot of electricity, the hydropower station built on the tributary of the Yangtze River has reached the Three Gorges, and the huge power generation of the Three Gorges Hydropower Station is not as great as expected. The dam has affected the stability of the local geological foundation. Gravity has begun to erode the steep banks of the Yangtze River in several places, and frequent water level fluctuations have triggered a series of landslide disasters, which have also destroyed the geological structure near the dam. Only the danger of landslides increases the frequency of earthquakes. In terms of ecology, the construction of the Three Gorges Project will have an impact on local large-scale ecology, such as destroying local vegetation, and
