Sometimes, humanity needs not only practical work, but also practical ideas. A few years ago, some people proposed to explode a large hole in the Himalayas, so that the warm and humid air flow from the Indian Ocean changes the natural status quo of drought and water shortage in northwest China, although this idea has finally become unrealistic and unworkable after the demonstration of scientists, but as an idea, it has attracted people's attention to the climate environment in the northwest from another level, so there is no harm. Today, let's talk about what it would be like if the Yellow River were to divert the Hexi Corridor.
Different from the explosion of a large opening in the Himalayas, the Diversion of the Yellow River in the Hexi Corridor has a certain operability, if it can be realized, it may make the two major deserts of China's Badain Jaran Desert and Tengger gradually disappear, changing the natural environment of the northwest region, close to the "Red Canal River" that the people in the northwest have longed for for a long time.
Let's first talk about what kind of diversion method. Step 1: Introduce the Yellow River from Gansu Baiyin Jingtai to Wuwei Gulang, Gansu. This practice has been realized at present, and people have introduced the water of the Yellow River in Jingtai into Gulang through the Xingdian Project; the second step: the Yellow River from Gansu Gulang to Zhangye through Wuwei Urban Area, which is somewhat difficult in the project, but it is not impossible to achieve, because the average altitude of Liangzhou District, where the Wuwei government is stationed, is more than 1600 meters, while the altitude of the Urban Area of Ganzhou District, where the Zhangye Municipal Government is located, is only more than 1400 meters. Step 3: Divert the Yellow River into the Heihe River in Zhangye and let it follow the Heihe River to Ejinna, the westernmost part of the Inner Mongolia Autonomous Region. This section of the line is ready-made, and the Heihe River has been running for tens of millions of years; the fourth step: let the yellow river flow through the Badain Jaran Desert and the Tengger Desert, and re-enter the Yellow River from Wuhai City in the Inner Mongolia Autonomous Region or Bayannaoer City in the Hetao Region. This section seems difficult on the surface, because the altitude of Ejin Naqi is between 898 meters and 1598 meters, which is a high and middle low-lying land in all directions, lower than Wuhai City and Bayannaoer. But historically, Ejin was once known as juyanhai, and people could achieve the return of the Yellow River by raising the altitude of water sources.

It should be noted that this is not a fantasy, the reality is that if the Ningxia Black Mountain Gorge Water Conservancy Hub Project starts construction, the water level of the Yellow River in the Baiyin and Ningxia Zhongwei sections of Gansu is bound to rise, and the water transfer from Baiyin Jingtai to Wuwei Gulang will be further sufficient, and it can even be said that it has diverted the Yellow River to the Hexi Corridor, and the remaining Wuwei to Zhangye sections are only one step away. At the same time, the Ningxia Black Mountain Gorge Water Conservancy Hub Project can also alleviate the water shortage problem in the Alxa Left Banner and Tengger Desert in the western part of the Inner Mongolia Autonomous Region, and improve the natural environment in this area.
Of course, this idea does not come out of thin air, in the records of China's ancient books, the Hexi Corridor itself is a large waterway from east to west. Before the Han Dynasty, people believed that the Yellow River had two sources, one source in the jishi mountain in present-day Qinghai, one source in Lop Nur in Xinjiang, and the two sources were connected by a dark river, and even Zhang Qian sent out to the western region, and there was also an important mission, that is, to explore the source of the Yellow River. In addition, in the records of China's ancient books, the Heihe River may not be an inland river, it may eventually flow into the ancient Chinese river (Yellow River). This is ridiculous and wrong in our eyes today, but the ancients could not have produced such a geographical illusion out of thin air, and we are not without the use of modern high-tech means and construction conditions to realistically divert the Yellow River to the Hexi Corridor.

History can provide us with some experiences to follow, and today, the development and development of the Great Northwest has been so severely constrained by water that the people of the Northwest have longed for the legendary "Red Canal River" in their hearts. Diverting the Yellow River to the Hexi Corridor and then returning to the Mother River via Ejina to Wuhai or Bayannaoer is not too difficult, the problem is that the Yellow River's water resources are limited, and the diversion will seriously affect the water problems in the middle and lower reaches of the river. The Yellow River basically has no tributary supply in the diversion section, so this requires the diversion and protection of the upper reaches of the diversion section and above, as well as the people in the diversion section to save water and conserve water.
It's very difficult to divert water and protect it, but people have been doing it all these years, and saving water and conserving water is the same thing. If the Yellow River is diverted to the Hexi Corridor under the premise of doing these tasks, people can protect the Qilian Mountains to make the Yellow River in the diversion section have a few more rare tributaries, and then use them in the abundant water season, such as introducing them into the Badain Jaran Desert and the Gobi Desert of Tengger. In this way, it can gradually not affect the downstream water use, and use the diversion to make full use of the purpose of the Yellow River water, which can not only further develop the local economy, but also make the two major deserts of Badain Jarin and Tengger, as well as some other desert Gobi, gradually become beautiful pastures and fertile fields.
