Flooded in the desert? There are many lakes in the Taklamakan Desert. Can the desert become an oasis?

Isn't the desert dry and rainless? Why do lakes exist? Can we take this opportunity to transform the desert into an oasis?

We all know that the Taklimakan Desert covers an area of ​​330,000 square kilometers, which is about the same as a small day, and it is also the largest desert in China.

The lakes that appear in the desert are like luminous gems and emeralds under the sunlight.

According to public information, the water in these lakes comes from the Tarim River. Since the beginning of this year, the precipitation in the Tarim River Basin has been the strongest in the past ten years.

Is it a heaven-sent opportunity that the Taklimakan Desert is expected to become an oasis and a new livable land?

With 10,000 square kilometers of land, the grain output can reach about 5 million tons, and 330,000 square kilometers is 160 million tons of grain.

If it really comes true, it will be no less than Columbus discovering the New World.

For a long time, human beings have had the idea of ​​transforming the desert. Will the heavy rain this time change the fate of the Taklamakan Desert? The seemingly logical inference turned out to be unexpected.

Flooded in the desert? Yes, you heard it right, there are many lakes in the Taklamakan Desert, but this may not be a good thing.

In order to turn a desert into an oasis, in addition to water, there is another important factor, that is, the ability to store water for a long time, especially groundwater.

Generally speaking, there are two causes of deserts, namely natural formation and man-made destruction.

If it is a desert caused by man-made damage to the environment, the sand will turn into mud after mixing with water. When the water evaporates, it will naturally condense into blocks.

If it is a naturally formed desert, since the sand comes from weathered rocks, after the sand is mixed with water, the water will flow away quickly, and after the water is completely evaporated, it will turn into sand again.

Undoubtedly, the Taklamakan Desert is a naturally formed desert. It is located inland and is dry and rainless all year round. The average annual evaporation is as high as 2500-3400 mm.

Under the erosion of wind and sand, the rocks rubbed against each other, and finally the Taklimakan Desert was formed.

Therefore, even if there are lakes in the Taklamakan Desert today, and take the opportunity to plant trees, if there is no guarantee of other water sources, these trees will hardly survive.

The appearance of lakes in the desert cannot change the fate of the Taklimakan Desert. Is it true that human beings are helpless in the face of the menacing land desertification?

The total land area on the earth is 162 million square kilometers, of which arid and semi-arid desert areas account for one-third, and are still increasing at a rate of 60,000 square kilometers per year.

It is easy to turn an oasis into a desert, but there are many difficulties in turning a desert into an oasis.

The harsh climate in the desert brings obstacles to desertification prevention and control, and the price paid is beyond imagination.

On the one hand, the trees that have been planted need to be constantly replenished with water. In order to prevent the rapid evaporation of water, it is often necessary to use techniques such as drip irrigation, which is difficult to operate.

On the other hand, the desert itself will also bring sandstorms, etc., which seriously affect the conditions necessary for plant growth.

It is no exaggeration to say that even in today's 21st century, human beings do not have many effective ways to face the desert.

What is even more worrying is that 43% of the land on the earth is facing the threat of desertification.

Compared with desertification prevention and control, what human beings should do is to protect the existing land and water sources and leave more opportunities for future generations.
