Today, Wu Ke will take you to see Chaerhan Salt Lake, which is worth 12 trillion. It is located in Golmud City, Qinghai Province, China, and it is also a tourist area. Because the weather in Chaerhan Salt Lake is hot and the sunshine time is sufficient, the water evaporates much faster than the rainfall. After a long period of wind and sun exposure, high-concentration brine is finally formed in the lake, which gradually crystallizes into salt particles, and the lake panel forms a thick salt layer, which is extremely hard.
This naturally formed salt layer is about 2 meters to 20 meters thick, and even if the car is driving on the surface, there will be no problem. When China built the Qinghai-Tibet Railway, a section of the road was built in Chaerhan Salt Lake. The entire Chaerhan Salt Lake is about160km long from east to west and 20-40km wide from north to south, with a total area of about 5,800km2.
According to experts' comprehensive exploration, the total amount of sodium chloride stored in the whole salt lake is at least 50 billion tons. What concept?
If all processed into edible salt, it can be used by more than 6 billion people 1000 years, which is the most important reason why our country is not short of salt.
However, Chaerhan Salt Lake contains not only sodium chloride, but also a lot of other elements, such as magnesium, lithium, boron, iodine and so on. Among them, potassium is the most abundant, and potassium is one of the essential elements of agricultural fertilizer. If it is not tested, it is estimated that many potassium elements used to produce fertilizers are purchased at high prices abroad.
In 1950s, due to the lack of potassium in China, we had to buy potassium from foreign countries at a high price. You should know how serious the consequences will be if we grow crops without using chemical fertilizers. You should also know that it is really difficult to fill our stomachs with high grain yield.
With the rapid development of agriculture, more people can have hot meals. At that time, in order to change the cause of potassium deficiency, the national leaders arranged for researchers to look for potash mines everywhere. The staff in charge of investigation in Qinghai accidentally discovered a large number of potash mines in Chaerhan Salt Lake.
1958, the state leaders also formally decided to establish a potash production base in Qinghai. Since then, the difficulty of not having potash fertilizer has been completely changed, and Chaerhan Salt Lake has been protected a lot because of its great value.
Today, Chaerhan Salt Lake has another name, the mirror of the sky. Because the scenery is so beautiful, it has also been developed into a tourist attraction. There is not much green here, only the sky and a lake, which is covered with white. These are all important basic materials.
With the development time getting longer and longer, the Qinghai provincial government has also put forward several requirements for the development of Chaerhan Salt Lake. To develop Chaerhan Salt Lake resources, it is necessary to achieve low input and high output, low energy consumption and less emissions, all for sustainable utilization. After all, it takes a long time to regenerate resources.
But to meet these requirements, it takes a lot of energy to develop and upgrade technology again and again, but this requirement is correct, because it is not achieved overnight, only sustainable development will not worry about these elements in the future. Even after hundreds of years, many elements have been mined now, and renewable ones have come out more or less.
Now do you understand why the price of edible salt is so low? That is to say, there is no shortage of edible salt materials in China, but we should control these resources to prevent large-scale destruction and affect the future. This is why China has been advocating energy conservation and emission reduction for so many years, and protecting the natural environment as much as possible.
If you go to Chaerhan Salt Lake one day, please remember to take care of the local environment, although researchers generally believe that the development of Chaerhan Salt Lake will be green soon, and this salt lake with a value of 12 trillion will play its role as much as possible to create a better living environment for domestic compatriots.
