Desert drought and water shortage is a common sense that we all know, and it is very common for this matter to be very vast in many desert areas. If it were earlier, it is likely that everyone would have an impression of deserts and areas. However, with the continuous efforts of our country, the implementation of tree planting and afforestation has greatly improved the situation of desertification in our country.
With years of efforts, large-scale greening has begun to appear in desert areas in my country, which is very good news for us, and the implementation of tree planting and afforestation has also been widely praised by everyone. However, a statement in a British scientific journal has caused great controversy over tree planting and afforestation in my country.
According to the British Science Journal of " Nature ", they believe that large-scale tree planting in my country may aggravate the shortage of water resources. According to this statement, forcibly planting trees on the edge of the desert and on the grasslands will make the desert, which originally had little water, drier and drier.
They believe that there is very little water in the desert. If a large number of plants are forcibly planted, the roots of the plants will accumulate groundwater, which will make the water in the desert less and less, which is quite unfavorable to the water resources of the desert itself. Moreover, when vegetation absorbs groundwater excessively, groundwater will become increasingly overdrawn.
The answer to this statement is of course no! The afforestation we have been doing all the time will not cause harm to the desert.
Moreover, large areas of greening plants began to appear in the desert. This is what we have seen with our own eyes. It is these planted plants that make the desert more qualified to conserve water sources, so this phenomenon is the biggest refutation of this wrong statement.
In fact, this statement does not have scientific basis, but rather a wrong understanding caused by incomplete understanding of the desert.
First of all, the desert is drought because it cannot retain water sources, but this does not mean that there is very little groundwater in the desert. In fact, the content of groundwater in the desert far exceeds that of the world's largest freshwater lake. In this wide area, although people cannot see water at the naked eye, it actually has many places to obtain water sources.
Because when deserts are formed, many people will live in some special natural environments. In this type of natural environment, glaciers often form around them. Glaciers can produce water sources by melting themselves.
For example, in the Tarim area in my country, there are large desert environments, but in this area, there are also a large number of glaciers, and water sources will be generated when the glacier melts. In addition, there is also a certain amount of groundwater and atmospheric water in desert areas, which can bring about a lot of groundwater in the desert. Therefore, the reason for water shortage in the desert is not that it has no water, but because the desert is very special geological condition that it is difficult to store water.
To address this problem, afforestation can help the desert absorb water. Moreover, in the first batch of trees and afforestation in the desert area, the selection of tree species should also be based on the local environment. It will not have much impact on the original desert environment, and can also be planted firmly in the desert area.
So even if the vegetation will absorb a certain amount of groundwater during this process, the overall scale is reasonable, and the harm to the groundwater sources in the desert area can be completely avoided.
and rationally planting trees and reaching a certain scale, it can effectively alleviate the emergence of desertification problems. This is the reason why our country has always insisted on this kind of thing.
As a country with a very serious desertification area in the natural world, our country has now relied on afforestation to greatly alleviate the desertification problem, and we have been persisting in this matter for more than 70 years.
Especially in the past 10 years, my country's afforestation area has reached 960 million mu. In terms of overall landform, my country's national forest coverage rate has increased to 24.02%. This change has made my country the fastest growing country in the world with the fastest growth of life resources.
In fact, in the world, other countries are also facing the troubles caused by the problem of desertification, which has a great impact on the overall development of the country. However, in this regard, our country is definitely an example of countries that can fundamentally change this problem and have greatly improved.
At the same time, in this regard, our country is also sharing some effective measures in our desertification control process with other countries in the world, helping other countries solve the desertification problem and actively contribute to the handling of global desertification problem.
