The Three Gorges Project can prevent floods, but it is very ineffective in controlling floods. In China, the northwest season is still very typical, and the rainfall distribution is very uneven. The Yangtze River is also a river on the ground from Yibin to Wuhan. In the past two thousand years, there was a flood in less than ten years. By 1998, the flood was still fleeting. At present, the huge storage capacity of the Three Gorges Project can effectively improve the despicable flood control norms and also effectively delay river siltation. The first is flood control, which is a very necessary step for people to live in harmony with nature. The Yangtze River Plain is the essence of industry and agriculture in China. However, the air 6- 17 meters below the flood is maintained by dikes with a total length of more than 33,000 kilometers. However, the ancient floods in the Yangtze River were frequent, and the flood power was weak until about 10. After the completion of the Three Gorges Dam, it can control the once-in-a-century flood and ensure the average and safety of China. In case of a once-in-a-thousand-year flood, * * * can separate the flood from the flood, which can prevent the dam from being washed away. History will prove that the Three Gorges Project of the Yangtze River is the guardian of indirectly ensuring the average flood control system and the safety of nearly 23 million mu of cultivated land and150,000 people's lives and property on the arteries of Beijing-Guangzhou and Beijing-Kowloon railways. The history of China is the history of harnessing the river. If the flood is not cured, the country cannot lose peace. In other words, without the Three Gorges Project, the Three Gorges Project can still be replaced in other aspects, except flood control. If the Three Gorges Project Department is completed, we will not have ineffective flood control skills, and people in Jianghan area will not be able to live in harmony with nature.
After the completion of the Three Gorges Dam, the rolling river will do work and generate electricity for the Three Gorges Hydropower Station, and stop the anti-regulation for 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; If the per capita annual output value is 6.5438+0 million yuan, 5.25 million people can be laid off. The Three Gorges Hydropower Station is located in China, and the transmission interval to the world's major load centers is about 1000 km, which is the interconnection center of future major power grids. After the power grid is connected to the grid, it can not only complement the world's fire, water and nuclear power, but also greatly improve the quality and efficiency of power grid operation. Therefore, the Three Gorges Hydropower Station will be the power regulation center of China in the future.
Compared with the backward reservoir area, the Three Gorges Project is a golden opportunity for convenient transportation and economic development. The 660-kilometer-long Yiyu River is very poor. There are more than 100 beach risks, dozens of single navigation sections and dozens of heavy cargo towing sections. Annual one-way shipping capacity100000 tons. After the completion of the Three Gorges Dam, all beach hazards, single navigation sections and towing sections will be swallowed up, and the navigation channel will be widened a lot. The 10,000-ton fleet will reach the sea through rivers, and the shipping cost will be greatly reduced, so that the annual one-way shipping will exceed 50 million tons. Then, the composition of the golden waterway that runs through central East China and West China is often conducive 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 beneficial to the situation, the South-to-North Water Diversion Project and aquaculture.
However, it takes so long for a resolution to be decided, and the influencing factors cannot be ignored. The secondary obstacles to the construction of the Three Gorges Project are cultural relics maintenance, ecological maintenance 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 invented so far. However, it is basically impossible to have enough time to dig up these precious cultural relics during the construction of the Three Gorges Project. According to reports, only one tenth of all cultural relics have been really excavated, which means that 90% of valuable cultural relics are buried at the bottom of the river. This is a very sour thing. Others are the scenic wonders along the Yangtze River of the Three Gorges, such as Zhangfei Temple, which have to be swallowed up by the river. This is a great destruction of China's historical civilization.
In terms of ecology, the construction of the Three Gorges Project will have an impact on the formation of large-scale ecology abroad, such as the destruction of foreign vegetation and the change of weather, 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 weather nearby has become very bad, but it is still very cold when it should be warm. There are also some central landslides, which are estimated to be related to the Three Gorges Project. Some organisms, such as fish, have changed their living conditions due to water storage and other reasons, which has an impact on reproduction.
There are also large-scale immigrants. People who once lived in the Three Gorges area had to remain the center of survival for generations. Under the new situation, the social achievements brought by immigrants, such as how to resettle immigrants and how to properly resettle them there, can not be ignored.
Every decision-making scheme of mass policy is formulated on the basis of reality, but the result of practice cannot be accurately estimated in advance. The quality of practice is probably an evaluation of the right or wrong of this decision-making scheme. The Three Gorges Project has been under construction for more than ten years. Judging from the current situation, the construction of the Three Gorges Project is still relatively poor, and the benefits are slowly emerging. It can be seen from practice that the current resolution scheme is fair and superstitious. I hope that in the future, this conclusion will still be correct. The Three Gorges Project will bring us more and more benefits, promote economic development, social prosperity and the poverty and weakness of the country.
In short, the benefits are flood control, power generation, improved shipping, improved situation, South-to-North Water Diversion and aquaculture.
The disadvantage is that it destroys the miracle of cultural relics and affects the ecological situation and the settlement performance of immigrants.
One third of people voted for the Three Gorges Project when they visited China, which shows that the Three Gorges Project is still a controversial topic. From the analysis of profit, it is obvious that we are doing it for one. For example, in terms of dynamic performance, the advantages definitely outweigh the disadvantages. According to experts' calculations, the electricity generated by the Three Gorges Project can be equivalent to several nuclear power plants, saving tens of thousands of tons of coal and fuel a year. It can break through the power closure of the United States and other eastern powers and break the bottleneck that restricts China's future economic development. It is also practical for today's low-carbon requirements, with the function of flood control and water storage, benefiting the country and the people and benefiting future generations. It is indeed a feat of benefiting the country and the people.
However, it should be noted that the disadvantages of the Three Gorges are self-evident. For example, in terms of ecological achievements and situation maintenance achievements, in terms of military achievements, it must do more harm than good! Tomorrow's world is not stable. As the only superpower in the world, the United States plays with fire everywhere! The Japanese next door are not fuel-efficient either. As Japan's economic strength grows, so does its ambition. Otherwise, the influence of Taiwan independence cannot be swept away. They will take advantage of the Three Gorges water attack station to take risks, which will be a great threat to the existence of despicable areas. This is a serious military worry that has existed in our country for some time!
