Recently, a new voice appeared on the Internet, saying that the South-to-North Water Diversion Project is useless and should be canceled. There are even some people who say that water should be diverted from the north to the south. How did this statement that at first glance it seems that IQ is a bit problematic come out?
In 2022, China announced the national groundwater resource reserves, and the results were very amazing, and the northern region, which has long been considered to be water-deficient, accounted for 95% of the country's groundwater reserves. In contrast, only 5% of groundwater is stored in the south, which is relatively rich in water resources.
It is precisely based on this survey that there have been so many voices on the Internet recently, saying that the south-to-north water diversion should be cancelled, or even the north-to-south water should be diverted. There are even voices saying that the call for the cancellation of the South-to-North Water Diversion Project is the opinion of some "experts and professors".
But what I want to say is that as long as you go to high school well, you should know why China is engaged in the south-to-north water diversion.
First of all, the most fundamental reason for the south-to-north water diversion project is indeed that the water resources in the northern part of China are not as abundant as those in the southern region. There is an imbalance in water resources between the north and the south. Therefore, it is necessary to build a national water conservancy project to allocate water resources across the country.
However, the direct cause is that there has been a large-scale underground cavity problem in northern China. Severe land subsidence has been triggered. It is not difficult to guess the cause of land subsidence, which is the large-scale overexploitation of groundwater in the north, resulting in the natural recovery of groundwater not keeping up with the amount of use. Fifty or sixty years ago, this was even common sense.
It can be said that in order to solve the shortage of water resources in the north, the south-to-north water diversion can only overexploit groundwater, which causes the problem of land subsidence. has made an indelible contribution.
The South-to-North Water Diversion Project is mainly divided into three parts: the eastern, western, and central routes.
The starting point of the middle line project is in the upper reaches of the Yangtze River, passing through the Central China Plain and the Loess Plateau, and finally reaching the North China Plain, which is mainly used to solve the problem of groundwater overexploitation in northern China.
The starting point of the eastern route project is in Jiangsu, along the Beijing-Hangzhou Grand Canal, and into the Huanghuaihai Plain. On the way, the eastern route project is more significant than solving the problem of water resource use, compared with solving the problem of water resource use, to regulate the water volume and reduce the probability of flooding.
The starting point of the western route project is in Sichuan, passing through the mountainous areas of central and western China, and finally transporting water to Shaanxi, Gansu and Ningxia. It's the irrigation problem that is solved here.
It can be said that the South-to-North Water Diversion Project is a comprehensive water conservancy project, and the use of water is only a part of it, or even only a small part. This project is not only used to solve the problem of drought in the north, but also to deal with the problem of flooding in the south and the problem of groundwater cavities in the north, and improve the utilization rate of water resources in the whole country. It has realized the optimal allocation of water resources nationwide.
Those who say that there is a lot of groundwater in the north and that they should exploit more are simply reversing cause and effect, and putting the cart before the horse.
Recently, China has investigated groundwater resources, and the groundwater in the north has been restored very well, which is clearly the credit of China's persistent maintenance of the south-to-north water diversion project in recent years.
Of course, the South-to-North Water Transfer Project is not exactly a perfect project. Of course, it also has its own shortcomings, such as unnatural water resources dispatch has caused certain damage to the environment, and several major floods in recent years have proved that China's south-to-north water diversion needs to be strengthened in flood storage function. These are the key points that need to be improved and upgraded in the future of the South-to-North Water Diversion Project.
In addition, with the continuous changes in China's natural environment and urban cultural development, we also need to adjust the overall project of the South-to-North Water Diversion Project.
However, having a defect and needing to be adjusted does not mean that you should choke on food. The South-to-North Water Diversion Project is of great political, economic, social and environmental significance, and it is an important project to ensure the sustainable use of China's water resources and the long-term stable development of the country.
In recent years, there have been a lot of strange theories on the Internet in China.
For example, Dong Yuyu, an expert in environmental physics at Peking University, proposed that farmers should ban straw burning when farming.
This suggestion put forward by him has harmed Chinese peasants for more than 10 years. Because the straw is not burned, the direct return to the field will lead to an increase in the probability of pests and diseases, reduce the quality of the land, thereby affecting the normal growth of crops, and even causing a serious reduction in yield in some areas. China's ancestors studied that farming requires burning straw, which is all blessed by lessons and lessons.
In the end, sure enough, it was found out that this person, an expert from Peking University, whose real identity was a spy from Japan, had been lurking in China for more than 30 years.
So we have to wonder, are these people really just trying to make themselves famous? For example, the experts who recently said that the South-to-North Water Diversion Project should be shut down, put forward these unreliable suggestions, and check their backgrounds, will they be able to catch one or more big fish?
