The Taklimakan Desert is rich in groundwater resources, so why not exploit it? What's the secret?

China's Taklimakan Desert is an endless desert. We all know that water resources are rarely seen in the desert. The long-term existence of large deserts can easily lead to sandstorms in the surrounding areas. Therefore, China has been vigorously planting trees and afforestation. become an oasis.

Deserts have a hard time storing water, and the desert floor is so hot that it evaporates immediately even if it rains. However, there are abundant water resources under the Taklimakan Desert. What is going on? Where does this water come from?

In fact, there are tall snow-capped mountains around the Taklimakan Desert. These snow-capped mountains often melt ice and snow, and these snow water will flow into the Taklimakan Desert. Because the desert has no vegetation, their ability to conserve water sources is relatively low, and some of them fall into the desert. In the desert, it becomes the groundwater in the desert.

According to this theory, there should be a lot of groundwater in the Taklimakan Desert. Some people think why not develop it and turn the desert into an oasis?

Why has the "underground ocean" in the Xinjiang desert not been exploited? What happens after mining?

Lop Nur is located at the easternmost edge of the Taklimakan Desert. Now there is a green field around Lop Nur. Many people think why not fully exploit the groundwater of the Taklimakan Desert and turn the entire Taklimakan Desert into an oasis.

In fact, the answer to this question is very clear, that is, it is not worthwhile to develop a desert environment, it is not conducive to the storage of surface water, and the extraction of groundwater is just drinking poison to quench thirst.

The reason why Lop Nur looks like it is now is because it was a place with abundant water and grass in history, because there were lakes and rivers in the early Tang Dynasty. At that time, the local people built wells, similar to the existing karez in Xinjiang, which is poor in water. Important measures for drinking water in the area.

In the 1970s, the Lop Nur area had become a dry lake. Now this area has basically formed a desert or saline-alkali land. People divert the underground water, which will easily cause the groundwater to become salty water, which is not drinkable. , also affects groundwater.

There is water in Lop Nur now because the potash in Lop Nur is relatively rich. Humans mine potash in large quantities in this place and extract it from the underground brine, but the brine that is pumped will quickly seep into the ground.

The groundwater in the Taklimakan Desert is divided into various situations, one is shallow and the other is deep. If you want to mine, you must first mine the shallow groundwater, but just like Lop Nur, generally the shallow water will have Water from other places is replenished.

The Taklimakan Desert is located on the mainland of China. It is very difficult for the water vapor from the ocean to penetrate. Moreover, the Chaklamakan Desert belongs to the temperate continental climate. The annual precipitation in this area is very rare, coupled with the hot climate. , the sand can be as high as 80 ℃, even if there is precipitation, it has already evaporated.

The evaporation of the Taklimakan Desert is greater than the confluence. Even if there are glaciers such as the Tianshan Mountains around, it can replenish a part of the water in summer, but this is still insufficient.

If we want to develop water resources, it will be difficult to restore to the old environment. The biggest feature of deserts is that they will continue to spread. Now we can prevent deserts from spreading. It is very good.
