Why can t the excess water be pumped to the Loess Plateau and the Tarim Basin in the north during th

The South-to-North Water Diversion Project built by China is to transfer water from the Yangtze River basin to the northern region and alleviate the shortage of water resources in the North China Plain. It is impossible to transfer water from the Yangtze River to the Tarim Basin. The Tarim Basin is located inland, the air is very dry, and the transfer of large amounts of water here will only lead to a waste of water resources.

In addition, the distance between the Tarim Basin and the Yangtze River is complex, and such long-distance water diversion may not only be economically uneconomical, but also bring serious ecological and environmental problems.

1. You can do this. But the amount of work is huge. In fact, there is no need to move far, you can dig some drainage channels to direct water to other places where there is no flood during the flood season to relieve the pressure. There was no need to lead as far as Natalim.

2. Long-distance water diversion cannot solve the problem of drought in the western region. Because the amount of water evaporated in these arid regions is high, the diversion water will evaporate in large quantities before it reaches its destination. It's a waste of water.

In addition, different geology leads to different water infiltration capacity, and in order to solve the problem of water shortage in the western region, it is still necessary to use water scientifically and save water. It is necessary not to flood the living environment, but to seek truth from facts and to improve the living environment in accordance with the actual conditions of various localities.

3. Drought is also a resource, China should reserve a part of arid areas, according to local conditions, according to different geological environments, choose suitable for human living space. Rather than blindly changing the same. Just like urban planning, the city center should have the city center, and the suburbs should have the suburbs.

You can't build skyscrapers everywhere, and you can't export all cottages.

I am a proponent of bringing water to arid areas, not just because of the amount of work.

During the flood season of the Yangtze River, excess water cannot be pumped to the Loess Plateau and Tarim Basin in the north because the distance is too far, there is no suitable waterway, and the pumping machine cannot pump it.

It is completely possible in this era, there are difficulties, and various experts and financial resources are needed, if the project of diverting floods from the south to the north can be solved, it will be a great initiative for the benefit of future generations! How many people have been lost in this year's floods, and how much money has been lost to the country! Fighting floods every year, there are floods every year, and I really hope that the experts of the Ministry of Water Resources will do a good job of demonstrating it.

How to quote? Dig a canal or transport? It's too difficult, and it's too dangerous to drain when there is a flood, this is not the era of Dayu, there are not many people, and now you have to consider the relocation problem when you move the ground slightly, and the pressure is too great

Seeing a very outrageous problem ...

Do you want to know the topographic map of China first?

It is necessary to cross the Qinling Mountains and transfer the floodwaters from the south to the north... It's so awesome.

Because the arid areas in the north are mainly the Loess Plateau, the Inner Mongolia Plateau and the major mountain ranges. Most of the flood areas in the south are river valley plains, and the water flows to the lower places, and the flood water flows from the north to the south, and the cost of diverting it to the north is too high.

Because the rainfall in our country is mainly brought by the monsoon, the rain belt is pushed from south to north. The north-south movement of the rain belt is strongly affected by the strength of the subtropical high.

When the middle and lower reaches of the Yangtze River are controlled by the subtropical high, the warm air pushes the rain belt to move northward to North China and Northeast China, and at this time, the rivers in North China and Northeast China will enter the flood season.

In summer, although the rainfall in the northern part of China is significantly smaller than that in the southern region, flooding may also occur. 70% of the rainfall in the Yellow River Basin is concentrated in summer and autumn, and there are frequent heavy rainfalls, and the rivers show a trend of rapid rise and fall.

It is too far away, and the cost is high, and the efficiency of human transformation and utilization of nature is still very low.

It is unscientific and reasonable to adjust a large amount of water in a short period of time, just as we cannot build more railways and roads according to the seasonal peak of the Spring Festival.

The altitude of the Tarim Basin is 800-1000 meters, and there are few high-altitude areas in the basin. The altitude on the way is 1250-1850 meters, which does not meet the characteristics of the Tarim Basin.

The basin is generally below 0 above sea level, and the plateau is about 1400 to 3000 or 4000 meters, which is related to the altitude and topographic area.

These three regions are all located in arid and semi-arid areas of China, and the ecological environment is very fragile.

Soil erosion is serious on the Loess Plateau, land desertification in the Tarim Basin is serious, grassland degradation and desertification on the Inner Mongolia Plateau.

Returning farmland to forests and grasslands, preventing wind and fixing sand, and maintaining ecological balance.

The Tarim Basin is the largest basin in China, with a total area of more than 400,000 square kilometers. In the interior of the Tarim Basin, there is the Taklamakan Desert, the largest desert in our country. You know, the area of our North China Plain is only 300,000 square kilometers, but it feeds more than 300 million people.

Many people dream of developing this barren land and making it a land of hope.

First and foremost, of course, is the issue of water resources. The climate of the Tarim Basin itself is arid, although other areas at the same latitude are dominated by plains, but the Tarim Basin is blocked by the Qinghai-Tibet Plateau, its own water vapor is very small, coupled with strong evaporation, it has become a desert-dominated terrain. If the Tarim Basin were not a desert, but a huge lake, there would be no need to worry about water resources, at least for the foreseeable future.

If the Tarim Basin were to be filled with water, it would be the world's largest inland lake. The combined area of the Great Lakes in the United States is only 10,000 square kilometers, while the Tarim Basin covers an area of 400,000 square kilometers, which is longer than the Beijing-Shanghai Railway from east to west. Surrounded by high mountains, the water depth of the Tarim Basin is also objective, with the deepest depth likely to exceed 500 meters.

If the Tarim Basin becomes a lake, the huge volume of water in this lake will completely change the climate of the northwest and northern regions, because the terrain is relatively closed, the evaporated water vapor here will not spread to the northwest and south, but mainly to the east, that is, along Gansu to Shandong. It will become a new source of water for our northern region, and the desert areas in the north will become oases under its influence, and become a place of hope suitable for human survival and development.

Of course, this is just a fantasy for us. Turning the Tarim Basin into a lake is almost impossible because there is no stable water source to feed it, and the annual evaporation here is as high as 300 billion cubic meters, equivalent to one-third of the annual runoff of the Yangtze River. It is impractical to divert water from the Yellow River or the Yangtze River.

Water is diverted from the Bohai Sea, through Inner Mongolia, along the Yinshan Mountains in the north of the Loess Plateau, all the way into the Tarim Basin. Seawater is inexhaustible, so it can indeed be regarded as a good source of water, but the biggest problem at present is that it requires huge manpower, material resources, and power resources to carry out the ladder lifting of water, and it is only in the stage of imagination at this stage.

Just look at the Caspian Sea, rain will form in the surrounding mountains, otherwise it is still a desert, the key to the climate is to look at the direction of atmospheric flow and topography, a lake still can't solve many problems, no matter how big the lake is, it can't be compared with the four oceans, not a heavyweight. But then again, it's better than nothing, after all, there are so many mountains around, and there are a lot of water vapor blocking and condensing.

If the Tarim Basin were flooded, the natural conditions would be very much better, because there was a shortage of water there, and there was the largest Sahara Desert. In this way, the situation of water shortage in our northwest can also be effectively improved. In this way, the whole natural environment may change a lot.

If the Tarim Basin becomes the Tarim Lake, it will become the world's largest lake, and its area will surpass the Great Lakes of North America, and these abundant water resources will improve the situation of water shortage in China, and at the same time, the climate type of the northwest region will be changed, the climate will be more humid, and the desert area will become an oasis.

The idea is beautiful, but the reality is hard. The Three Gorges is also more than 900 kilometers away from the nearest desert, the Mu Us Desert. Moreover, the altitude of the Three Gorges is only one or two hundred meters, but the altitude of the Mu Us Desert is more than 1,000 meters, and such a huge drop is destined to be impossible to drink water from the Three Gorges to the desert.

Moreover, the water of the Yangtze River comes and goes as fast as it comes and goes during the flood season, like a storm, and the volume of water is so huge that human beings cannot completely absorb it, so they can only discharge it.
