Following the Hexi Corridor, Li Ke soon re-entered the Guanzhong territory.

"Brother Ke, there is a fan here who left a message saying that he could go to their hometown to have a look, I checked, and their hometown should be a village located on the Loess Plateau." The little assistant on the road has been paying attention to Li Ke's fan messages and so on.

"Oh? Is it on our route? Li Ke asked with some curiosity.

"Yes. He said that his hometown has a lot of history, and it has been passed down for more than a thousand years, and it is said that it has been passed down since the time of the Holy Sect. The assistant nodded, "We have a little detour, but there are not many detours." ”

"Then we'll get there." Li Ke nodded very dryly.

When driving into the Loess Plateau, Li Ke's car navigation also came with an introduction ahead.

"We are about to enter the Huangtu Plateau Nature Reserve, do you need to introduce the details?"

"Introduction." Li Ke directly opened his mouth and responded.

"Okay, the Loess Plateau Nature Reserve, established in 477 years of the Tang Dynasty, is one of the first seven large-scale first-class nature reserves established in the Tang Dynasty, along with the Taklamakan Ecological Nature Reserve, the Qinghai-Tibet Plateau Qiangtang Nature Reserve, the Hoh Xili Nature Reserve, the Xihanhai Grassland Nature Reserve, the Ili River Aral Sea Nature Reserve, and the Kavir-Lut Desert Nature Reserve."

"These seven nature reserves are important environmental nodes that have been discovered by Datang scholars for many years and are related to the entire Datang ecosystem, so all grazing, planting, water and soil, and wildlife groups in the reserve have strict regulations."

"At present, there are a total of 76 first-class nature reserves in Datang, distributed in various locations in Datang, all of which have a common characteristic, that is, their environmental and ecological systems are very fragile, and once over-logging, it may cause a large number of animals and plants to disappear, or it will cause irrepressible deterioration of the ecology."

"The Loess Plateau Nature Reserve, since the time of the Holy Father, has consciously protected and restored the water and soil, although its bottom is a large amount of loess, but after thousands of years of forests, plants and other planting, the current vegetation coverage rate of the Loess Plateau has reached 93%."

"Among them, the forest coverage rate has reached 79 percent, and according to the survey and research of the Ministry of Forestry and Ecological Protection of the Tang Dynasty, the vegetation and forest coverage rate of the Loess Plateau have basically reached the level of the summer and Zhou periods."

"And this former birthplace and birthplace of Chinese civilization, after more than 1,000 years of forests and vegetation, a large amount of humus has begun to be deposited on the surface of loess."

"Although it may not be able to form black soil like the two most important black soil plains in the Tang Dynasty, it has been determined that the humus of the Loess Plateau is already being overloaded and deposited, and the excess humus can give birth to more plants and vegetation."

"Since 132 years ago, the Datang Ministry of Forestry and Ecological Conservation announced that human intervention in the Loess Plateau Nature Reserve will be suspended, and the internal vegetation environment will evolve by nature."

"In the foreseeable future, the Huangtu Plateau Nature Reserve will become one of the most species-rich nature reserves in the Tang Dynasty."

With the introduction of the car machine, Li Ke took a deep breath, to be honest, he didn't expect to be able to stick to this policy.

And the effect of persistence is so good, what the Loess Plateau of the country where he used to be in looked like during the founding of the country, Li Ke knows very well.

The whole country does not know how much money was spent, and how many years of planting and restoration took it to make the Loess Plateau reach 63 percent when Li Ke crossed to the Tang Dynasty.

In the early days of the founding of the People's Republic of China, its vegetation coverage rate was only 34 percent, and at that time, some people commented that the Loess Plateau was the most unsuitable place for human habitation.

But even if it reaches 63 percent, there is still a long way to go to restore the Loess Plateau, especially what the world has done, and it is a long way to stop human intervention.

Many people may think that when trees are planted, can't vegetation grow? Why continue to invest in human interventions.

That's because the formation of a forest, especially the formation of a natural forest, has a complete ecological circle of vegetation, while the artificially restored vegetation and forest have only completed the most preliminary restoration, and the water and soil are maintained first.

The subsequent development of forests and vegetation still requires intervention, and it will be continuous intervention for many years, because the plant species in the forest must be diversified, otherwise these forests will also die in large areas.

And if we want to completely abandon human intervention and hand it over to natural evolution, like Datang, I am afraid that it will take at least a hundred years before it may be possible to initially let go of human intervention and turn to key monitoring.

To be honest, Li Ke was a little moved, 93 percent of the forest coverage rate, that is, almost the entire reserve is covered by forests and vegetation, and human activities have basically been reduced to a minimum.

"Please note that the use of fireworks is strictly prohibited in any forest outdoors when entering the reserve, and it is not allowed to cross the virgin forest without permission. Any unauthorized crossing will result in administrative penalties, fines, or even prison sentences. ”

There was a warning sound from inside the car, and the two sides of the highway have become dense primeval forests, and in order to avoid the damage of plants to the highway, some twenty or thirty meters of separation strips were made on both sides of the highway.

Obviously, these barriers also need to be cleaned up manually, otherwise these plants will soon fill both sides of the road.

The location given by this fan was a little far, and after getting off the highway, he probably drove more than 100 kilometers of winding mountain roads before Li Ke arrived at his destination.

Zhangjia Village.

When Li Ke's car came to the entrance of the village, he saw such a plaque, the whole village was surrounded by forests, and the roads in the village had been hardened, but when Li Ke's car entered the village, he could see the curiosity in the eyes of the villagers outside.

Drove to the place where the village committee was located, there was a small square here, but at the moment there were more than a dozen old people sitting on the square, and Li Ke parked the car on the side of the road before getting out of the car.

did not let the assistant start the broadcast, but Li Ke chose to learn about it himself.

Seeing the young people coming, these old people were obviously a little curious in their eyes, "Hou Shengzi, where did you come from?" ”

An old man with white hair asked with a smile.
