Land desertification is getting worse, why can trees stop land desertification?

Entering the depths of the northwest is an extremely challenging season, with the temperature difference between day and night, and the harsh climate, so that everyone who comes here can truly feel the most difficult place in China. But this is by no means the hardest time, and the real hardest time is when you enter the depths of winter. But no matter how bad the conditions, poplar forests.

Always stay here.

A thousand years of immortality, a thousand years of immortality, a thousand years of immortality, three thousand years of "mythology" to describe poplar forest is not an exaggeration. In Ejina.

In the three places of Mulei and Hami in northern Xinjiang, in addition to the poplar forests with yellow leaves, there are still many immortal trees on the earth.

At first, we thought it was vandalism, but after learning about it, we realized that these three places are listed as protected areas, and the dead wood that fell on the ground is a natural death.

Locals tell us that withered poplar forests like this will hold out for hundreds of years before they fall, and that the roots rooted deep in the desert allow the trees to resist the wind and sand.

Even fallen dead wood takes a long time to decay and eventually become part of the desert. And it is this kind of tenacity that poplar forests are known as the strongest trees in our country.

China has the world's largest poplar forests, but most of them are concentrated in China's Xinjiang region, in the last century due to the lack of environmental awareness, poplar forests have suffered fatal damage, many of the original poplar forests were cut down as firewood to burn, its area has shrunk rapidly, to today is less than half of a hundred years ago.

With a series of protection policies and people's gradual recognition of the role of poplar forests in resisting desertification, coupled with the fact that poplar forests have become a local tourism feature in recent years, the damage to poplar forests has been alleviated, and now these are sticking to the Gobi Desert in China.

The trees in the area were able to survive and slowly recover.

With the boom in tourism in the northwest and China's development of the western region in recent years.

Access to the Northwest Territories.

The infrastructure is gradually improving, and the tenacious life of this bitter cold land in the past is slowly being known to the public. We also hope that tourists will not only be attracted by the beauty of poplar forests, but also be able to understand and protect poplar forests with a protective mentality, knowing that most of the poplar forests in the whole world are in China.

Because trees are generally very tall and leafy, they will be weakened a lot when the wind blows in the desert and encounters large trees, so it can stop the wind and sand from getting bigger and bigger.

Because the root system of the tree develops downward, the root system of the tree will grasp the soil downward, and at the same time, it will lock in water, and the soil is not easy to lose. Trees on the ground will reduce the wind speed so that the wind doesn't take away more soil.

Because the roots of the tree will take root in the soil and then hold the soil in place.

1. Desertification in the narrow sense (i.e., desertification) refers to the process of environmental change similar to desert landscape in the fragile ecosystem due to excessive human economic activities that destroy its balance. That is, to cut down trees indiscriminately, so that the balance of the land is destroyed and turned into sand!

2. Land desertification: land degradation in arid, semi-arid and dry sub-humid areas caused by various factors, including climate variability and human activities. Desertification in the narrow sense (i.e

Desertification refers to the process of environmental change similar to desert landscapes in areas that resemble desert landscapes due to excessive economic activities by humans in fragile ecosystems.

3. Land desertification: refers to arid and semi-arid areas, due to the influence of natural factors and human activities caused by the destruction of ecosystems, so that the original non-desert areas have a similar desert environment changes. In arid and sub-arid areas, under the conditions of arid and windy and loose sandy surface, due to the irrational economic activities of human beings, the environmental degradation process similar to desert landscape has occurred in the areas of the original non-sandy desert, which are mainly marked by aeolian sand activities and undulating sand dunes.

There is not much difference between land desertification and land desertification, but the severity of desertification is higher.

economic activities and other factors, resulting in the degradation of land in arid, semi-arid and drought-prone sub-humid areas.

The formation of land desertification is a complex process, which is the result of the interaction between unreasonable human economic activities and fragile ecological environment. Natural geographical conditions and climate variation have created conditions for the formation and development of desertification, but the process is slow, and human activities have stimulated and accelerated the process of desertification, which has become the main cause of desertification.

When the climate dries, desertification develops; When the climate becomes wetter, desertification is reversed. Global warming, increasing drought in the northern hemisphere, and the trend of semi-aridization have all contributed to the intensification of desertification.

Population growth and economic development have put too much pressure on the land, and over-cultivation, overgrazing, deforestation and irrational use of water resources have led to serious degradation of land, destruction of forests, gradual drying of the climate, and eventually desertification.

Land DesertificationDeserts are a product of an arid climate, and there were deserts on Earth long before the advent of humans. But there is no insurmountable boundary between the desolate desert and the fertile steppes. With water, lush plants can grow on the desert and become an oasis full of life; Without water and plants, green spaces can quickly degenerate into gravel.

In order to get more food, people will open up wasteland for farming and overgraze regardless of climate and land conditions; In order to solve the fuel problem, regardless of the consequences, trees and grass are cut and cut indiscriminately. The arid and semi-arid regions, which were already dry and windy, are now ravaged and the vegetation destroyed, with less precipitation and stronger winds, strong winds eroding the topsoil, increasing the amount of sand and slowly developing sand dunes. This turns arable land into desertified land that is not suitable for grazing and farming.

Land desertification is a sign of environmental degradation and a positive feedback process of environmental instability. If fundamental measures are not taken, the process of land erosion and desertification will not stop automatically, but will intensify development.

Desertification.

Bai may be natural. du

Desertification as a natural phenomenon is caused by the drying out of the earth.

DAO dry belt moves.

The resulting climate change has led to localized desertification. However, most of the causes of desertification around the world today are attributed to human causes; Rapid population growth, over-cultivation of land and livestock have made the land unsuitable for farming.

Desertification refers to the decline or even loss of productivity of organisms on the land. The main cause of the cause is the destruction of the natural environment by human beings. One of the places where desertification is most pronounced is in Sahel, on the southern side of the Sahara Desert.

In the northern part of the area, sheep and camels are raised in a nomadic or grazing desertification pattern, which eats up the entire area of vegetation, resulting in a bare patch of land. In the wetter south, the whole area gradually became barren due to the overbreeding of domestic animals and the fact that the cultivated land, which was originally only a square inch of land, could not afford to continue farming.

Coupled with the lack of water, people began to dig well water, and when people gathered for water, more livestock were raised, which again accelerated the deterioration of the environment and contributed to desertification, and this vicious circle made life very difficult for the people in the area. There is no rainy season in the Sahara Desert, so there is no rainfall, but as long as there is the slightest moisture, the plants that sleep in the ground will rush to sprout, but soon, they will be eaten up by overgrazing livestock...So the desertified soil is still expanding silently....

It is caused by human indiscriminate cutting and deforestation, and reclaiming a large amount of forest land for farming.

Water is the source of life......Environmental issues.
