In the afternoon, Zhang Wei stayed in his palace and did not go out, and did not allow others to disturb him. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

He first synthesized five academician-level experts in geology, botany, meteorology, and environmental protection, established a desert management research institute, and worked with them to study the geological impact, vegetation improvement, and environmental changes after the migration of mobile sand dunes in the desert.

Zhang Wei first printed out the topography map of the West Asian Peninsula from the system, and purchased some related books for their reference.

Zhang Wei does not have any confidence in the desert management, Saudi Arabia, which was rich and wealthy in his previous life, did not manage the desert well, not to mention that he is now unwilling to invest a lot of money; He was now thinking about whether there would be any unexpected consequences after the sand dunes were removed.

Zhang Wei is also poring over books on the Arabian desert.

The Arabian desert includes the Great Nefd Desert, the Dahna Desert, and the Rub al-Khali Desert.

Nefde Desert (also known as Tiangu), located in the north of the Arabian Peninsula, is the second largest desert in the Arabian Peninsula, 450 kilometers long from east to west, 250 kilometers wide from north to south, with an area of about 57,000 square kilometers, an average altitude of 760 meters, many mobile sand dunes, large sand dunes are as high as 10 meters, mostly composed of red sand grains. During the rainy season, aquatic weeds are generated, which can be grazed and passed. The dry season is extremely dry, and there is no grass, making it extremely difficult to pass.

The Dehna Desert, located in the eastern part of the peninsula, is located between the Great Nevd Desert and the Rub al-Khali Desert, running east-west and in a crescent-shaped distribution. It is 1200 kilometers long, 35~90 kilometers wide, 360~460 meters above sea level, and most of the dunes are more than 10 meters high. Although the desert is mostly white sand dunes, there are more aquatic grasses, and the pastures are larger than the Nevde Desert, which is easy to navigate in the narrow parts of the desert.

The Rub al-Khali Desert is a large desert in the tectonic basin in the southern part of the peninsula, with an area of about 650,000 square kilometers, a length of 1,200 kilometers and a width of about 640 kilometers. Most of them are large flowing sand dunes arranged in parallel, some of which are 300 meters high and 20 kilometers long, almost a sand mountain. At the higher groundwater level, there are local oases that form good pastures. The western desert is 100-500 meters above sea level, mostly gravel desert, with swamps and salt lakes between sand dunes.

As can be seen from the information, there are many mobile sand dunes here, and these mobile sand dunes are very convenient for him to operate, and it is the dry season, which is very beneficial to him.

Due to the relative scarcity of information and the fact that no results could be achieved on paper, several academicians suggested going to the site for investigation, which was in line with Zhang Wei's intention, and decided to leave early tomorrow morning to use the base's airship, and the transportation was very convenient.

The airship flew a short distance to the southwest, approaching the edge of the desert, where some date palms could be seen, but in this hot season, the leaves of these trees were not green, but grayish-yellow, and looked half-dead and lifeless.

The farther you fly inland into the desert, the higher the temperature feels, even the trees and grass are rare, there is sand and gravel everywhere, and you can't even see the trail on land, and you can't see any signs of human activity.

After flying out of more than 100 miles, the surface of the sand dunes is blown by the wind, showing waves like fish scales, and moving slowly, but the wind is less in this season, the speed of movement is very slow, and there is no sandstorm.

Faced with so many flowing sand dunes, Zhang Wei was going to do an experiment first, this was the first time to load things into the system on a large scale, and he had to be cautious.

So I did the experiment first, controlled it with my mind, and chose a circle with a radius of 500 meters with the airship as the origin, and took 3 meters of gravel down.

In the blink of an eye, a regular round pit appeared on the sand dune, and many small animals were left in the round pit, and it seemed that the living animals had been filtered out.

To everyone's disappointment, 3 meters underneath, it was still dry and gravel, and there was no damp smell at all.

Zhang Wei continued to do the experiment, this time it was deepened to 10 meters, and the sand pit was still very dry, and there was no moisture at all.

Tang Jiamin, an expert in desert management, said: "Your Majesty, the reason why the desert is called a desert, extreme lack of water is one of the causes, if there is water here, it can also become an oasis, now it is summer, and in winter, water vapor blows from the Mediterranean, and there is rainfall, it will become a good winter pasture for nomads." ”

Zhang Wei asked: "The herders here have been driven to the Ottoman Empire, and there will be no more herders coming to graze in winter. ”

Tang Jiamin said: "Your Majesty, this has certain benefits, but it is very difficult to have an essential change, to control the desert, first of all, to fix the sand dunes, reduce the flow of sand, and then the most primitive species such as moss will appear, which will play the role of soil consolidation, and then the grass, shrubs and tall trees will gradually increase; The corresponding increase in the groundwater level is also conducive to the growth of tall date palms and other trees; However, the temperature here is so high and the evaporation is too high, either it can be changed by manpower, or if a freshwater lake is introduced, it will soon become a saltwater lake. ”

Zhang Wei thought to himself, since it is difficult to govern, then directly move all these sand dunes away.

Letting his thoughts spread, along the direction in which the airship flew, a sand-free strip appeared on the ground that was dozens of kilometers wide and from a few meters to a depth of tens of meters, the original sand dunes were gone, and the ground was presented with bare bare rocks and a large number of small animals that were filtered out.

After flying more than 100 kilometers continuously, Zhang Wei equipped the huge system warehouse with gravel; When you see the ground, you are very surprised, the tall sand dunes have disappeared, which is much easier than sand fixation, without this flowing sand, the surface is all rocks, and there is no need to treat it.

Now Zhang Wei's system warehouse is nearly 2 billion cubic meters large, filled with local red sand, which can be used to move mountains and reclaim the sea, and also save the trouble of controlling the desert.

Tang Jiamin and several experts were extremely excited, especially Tang Jiamin, and said happily to Zhang Wei: "Your Majesty, I didn't expect your skills to be so high, if this is the case, we should go to the Rub al-Khali Desert, where there are more mobile sand dunes, sandstorms are particularly frequent, regardless of whether there is damage to the environment, this can at least eliminate sandstorms." ”

Zhang Wei was also very happy, and said with a smile: "I didn't expect it to be so easy when loading sand, at first I had the impression that it could not be fixed on the earth, it seems that this sand dune is not a fixed object; With a good start, at this rate, it will not be difficult to carry away all the moving dunes of the Rub al-Khali Desert; I'm also going to look at the consequences and effects of reclamation with this sand, and if it doesn't hurt, I'll just have to run a few more times. ”

Li Li, a geological expert, said: "Your Majesty, there must be an impact, which has a great impact on geology and ecology, and the absence of mobile sand dunes is also good for other places; There are still more unknowns that need to be studied and observed, such as whether there is still quicksand scraping from other places? What happens when there is natural precipitation in winter, etc. ”

Zhang Wei said with a smile: "Academician Li, the question you raised is the question you want to study during this time, and when your research has results, I will move mountains and reclaim the sea with you, so that you can witness this historical moment that will change the world." “

Tang Jiamin said: "Your Majesty, we can only witness the removal of mountains, and the reclamation side still needs relevant personnel to cooperate with the study." “

Zhang Wei said: "Yes, you also need to study it carefully, you can't act blindly, you are responsible for studying the relevant work of moving mountains!" “

"Yes, Your Majesty!"
