Lop Nur is resurrected, where does the water come from? Become rippling, at least feed millions of people
Even though it was an oasis thousands of years ago, in recent years, due to climate change and human development, Lobupo has gradually become a desert. In the impression of modern people, this area is almost associated with death and drought. Recently, however, someone discovered that Lop Nur has actually been resurrected. The once dry areas have become rippling blue waves again. Where did these waters come from? Will it help the region recreate the desert oasis of yesteryear? If this water is fresh water, it is expected to feed at least tens of millions of Chinese if it is developed into farmland.

In addition to the title of the sea of death, Lop Nur is also known as the ear of the earth, because from the satellite map, the shape of the area is very similar to an ear, and the history of this area can almost be said to be the vicissitudes of earth's geological changes. The best proof is that only 2,300 years ago, there was a huge desert oasis in the Lop Nur area, which was enough to support such a powerful and brilliant ancient civilization as the ancient country of Loulan. Until 1931, some people measured its area to reach 1,900 square thousand square meters. After 11 years, its area has reached 3,000 square kilometers, which is 600 square kilometers larger than today's Taihu Lake. It can be said to be the largest lake in the country.
However, in the past few decades, more and more people have settled around the Tarim River, which provides water for Lop Nur, and constantly draw water from the river for irrigation and other production and living needs. At the same time, the local climate is gradually drying, and eventually more A combination of factors led to the disappearance of Lop Nor.

The disappearing water body has brought another gift from nature, that is, a large number of potash mines discovered by Chinese scientists underground in the area. Although the name has the word salt in it, it is not for eating, but for production. An important raw material for chemical fertilizers, you must know that China is a country that lacks potash resources, but has a large demand. In order to meet the needs of agricultural development, China decided to carry out large-scale development of this area. In 2000, it established the world's largest potash Salt Development Company, and the way this company develops local underground minerals is to extract the deep underground brine and discharge it into the open-air evaporation pond, so that the poisonous sunlight can be evaporated with high efficiency. This production method has also led to the emergence of a huge water surface with an area of more than 10,000 square meters in the area. From the air, it seems that Lop Nur is being resurrected.
Of course, such brine contains much higher salt and other harmful substances than normal fresh water, so it is difficult to nourish the plants on the ground. Therefore, even if the water surface area is very large, there is still a relatively lack of vegetation around the area, so it is difficult to It is developed into farmland.

In short, the disappearance of Lop Nur is most likely caused by human influence and natural changes. Even China, which has advanced technology, can currently only extract underground brine for the development of potash mines. Therefore, it is difficult to revive Lop Nur by relying on the current science and technology under the control of human beings. However, in the near future, China may be able to develop a method for ecological restoration in this area, so that the disappeared Lop Nur will become rippling again, and can be used in A large amount of farmland has been reclaimed on its shore, feeding millions of Chinese people, so that the Chinese people can further get rid of a series of social and economic problems caused by the lack of cultivated land, and promote the further development of the country.
