The only county in China without trees: What's the secret of planting a tree for a thousand years?

Naqu county, a county town where there are no living trees.

As the saying goes, it takes ten years to plant trees and a hundred years to cultivate people. Trees have witnessed many human activities and contained many human memories. In many people's childhood memories, there is always a big tree under which we play and enjoy the cool ... The tree is a frequent visitor in many people's memories.

Trees can be seen on islands, mountains, snow, and even in many places with bad environment in the desert.

However, many people living in Naqu County may never see a few trees in their lifetime. The trees we can see everywhere are hard to find in Naqu County. For thousands of years, no tree can survive and take root in the land of Naqu County.

Naqu county belongs to Naqu area of Tibet, and it is the political center, economic center, cultural center, transportation center, information center and communication center of northern Tibet. Naqu County has an average elevation of more than 4,450 meters, with a total area of160,000 square kilometers.

It stands to reason that there should be no trees in such an important place and such a vast area, even in Tibet where the environment is relatively harsh.

Why can't Naqu County keep a living tree?

In the vast area of Naqu, there are many precious wild animals, such as antelope and swan, as well as precious plants such as Cordyceps sinensis and Saussurea involucrata, and many precious mineral resources.

Naqu is located in northern Tibet, between Tanggula Mountains and Nyainqentanglha Mountains. At first glance, you can see the continuous mountains and grasslands of vast expanse. Many important rivers also flow through here. Lakes, snowy waters, grasslands, although the environment here is fragile, it also has a different kind of beauty.

There are many reasons why the trees in that song are not alive:

If you want to stand up, you have to stand up. If a tree wants to grow tall, it must be firmly rooted. Naqu is located in a high altitude area, and the thin frozen soil layer is distributed in this area. The natural fertility of frozen soil is very low, and even many simple agricultural activities are unbearable without reconstruction. With the change of seasons and the temperature of Naqu, frozen soil will be frozen and thawed. Supporting grasslands is its limit, not to mention trees.

If the roots are not firmly rooted, they naturally cannot stand the baptism of strong winds.

Naqu mountain area is widely distributed, and in the plateau hilly area, there are naturally strong winds raging. Every winter, the Naqu land will be ravaged by strong winds, and the natural channels formed between mountains will strengthen the narrow tube effect of wind.

How many plants can survive this gale? Perhaps, even the grown trees can't resist the wind. What's more, the newly planted saplings are dying after such a strong wind.

So it is difficult to take root and grow, which is also an important reason why the trees in Naqu have no vitality.

Water is the source of life, and the growth of trees is naturally inseparable from water.

The land in Naqu can't keep water, which is an important reason why there are no trees in Naqu County. Naqu soil layer is shallow, although the precipitation is not small, but because of the strong permeability of frozen soil and a lot of water, the soil can't keep water, and trees are not easy to get water; Frozen soil is a huge obstacle to the root development of most trees, with underdeveloped roots and poor water absorption capacity of trees. In addition, under the influence of light and other factors, water is also an important factor restricting the survival of Naqu trees.

The trees in Naqu are not alive, not only because of simple factors such as light and hot water, but also because there are many other factors in its environment, which together constitute the hometown of Naqu tree.

However, although Mother Earth did not bring the tree to that song, the industrious and intelligent people of that song are still trying to make the tree take root and sprout there.

Since ancient times, people living in Naqu have never given up the idea of letting trees grow on this land.

With the increasing ability of human beings to transform nature, Naqu people began to "transform" in Naqu.

In the early days of Naqu, many species with strong viability were introduced, and many species that can survive and develop in deserts, snowfields and mountains were transplanted to this land. Although all the transplanted trees have strong vitality, the living conditions of these trees in this famous treeless village are not very good. ...

Despite many attempts, it is still difficult to get rid of the title of "a country without trees"

At that time, it was difficult for people to overcome the complex and changeable climate and unique geographical environment of the plateau.

With the development of the times and the progress of science and technology, many "steel forests" have appeared on Naqu Island, and "trees" made of cement and steel bars have appeared on this land. With the emergence of more and more "steel forests" in Naqu, people living in this land of Naqu are increasingly eager for the emergence of real trees.

There was even a reward at that time, hoping that the tree would grow in that song. Although many people have tried, no one has planted it successfully. The reward amount is getting higher and higher, reaching hundreds of thousands at a time, just to find the tree that can survive in that song.

The country has responded to the wishes of many people who have high hopes for trees like people in Naqu area. Xizang Autonomous Region has successively carried out large-scale land greening actions, eliminating "treeless villages", "treeless households" and "treeless units", and the famous treeless town Naqu has naturally become an important concern.

Gradually, with the efforts of the government and people of Naqu, with the settlement of scientific research teams, many plans that could not be started in the past began to start, and more and more people devoted themselves to the cause of planting trees in Naqu.

The Naqu government has also specially built a trial planting base. After a long period of scientific research and experiments, Naqu area began to scientifically plant individual trees.

From 2065438 to March 2007, the Naqu regional government started the research and development of key technologies of urban plants and the demonstration project of greening mode in Naqu region.

That singer is getting closer and closer to the answer to this Millennium problem.

After years of planting and improvement, Yanagi Takayama, a tree with strong vitality, has adapted to the complicated environment and survived in this land.

Today, that song has also been covered with this hard-won green seedling. I believe that one day, that song will become the Garden of Eden for plateau trees.

Even if the weather is not beautiful, even after many attempts, people living in that song have not forgotten their original dreams. After a lot of efforts, trees have grown in the song that originally had no trees.

In life, we all encounter difficulties. Many people feel that there is no hope or future, so many people give up early.

Thousands of years later, Naqu people still don't give up. Will a temporary disadvantage make us stagnate?

The indomitable spirit of people living in this land of Naqu is most worth learning.
