Can the desert immigrate, Zhihu?

Desert mainly refers to the barren land where the ground is completely covered with sand, plants are very scarce, rain is scarce and the air is dry. Desert is also a "sand curtain", an area with drought and water shortage and scarce plants. Desert areas are mostly beaches or sand dunes, and rocks often appear under the sand. Some deserts are salt flats without any vegetation. Deserts are generally aeolian landforms. There are sometimes valuable mineral deposits in the desert, and many oil reserves have been discovered in modern times. There are few residents in the desert, and resource development is relatively easy. The desert climate is dry and it is also a paradise for archaeologists. Many human cultural relics and earlier fossils can be found.

The water in the desert is not necessarily in the form of rain. Friends who visit a famous Taklimakan desert in Xinjiang should know that this desert has an endless sea and a few cacti beside it. Not only that, the area of this sea is about 1000 km, which surprised many people. Where does the water in this desert come from?

Even here, some people suspect that it may not be a real lake, but a mirage, which is a very common phenomenon in the desert. But when people really touch it, they find that it is really water. This water area is what we call Lop Nur. It is said that the water here is particularly rich, and it is also a particularly important saltwater lake in our country, but because of immigration, the water here has been drained.

Therefore, it gradually merged with the desert, and more researchers think that the water storage here is particularly large, especially the potassium salt reserves, which are as high as 65.438+0.22 billion. This amazing number surprised many people. In fact, many people have no idea about this number, but I am here to tell you that such a storage capacity can be used by people in our country and even the whole world for more than 200 years. It took a lot of effort to get through here. First, we pump water from the bottom and then put it on the material to dry. In this way, we can get the salt we want, and the water we see is the waste water collected from the bottom.

Of course, the air temperature is too high, the moisture in the air does not reach the condensation temperature, or there are no condensation nuclei, which may also be a reason.
