Following the Hexi Corridor, Li Ke quickly re-entered the Guanzhong territory.
"Brother Ke, there is a fan message here saying that you can visit their hometown. I checked and found that their hometown should be a village on the Loess Plateau." The assistant on the road has been paying attention to Li Ke's fan messages. etc.
"Oh? Is it on our route?" Li Ke asked curiously.
"Yes. He said that his hometown has a lot of history, and it has been passed down for more than a thousand years. It is said that it was passed down from the Holy Sect era." The assistant nodded, "We took a slight detour, but it was a detour. There aren’t many places.”
"Then let's go there." Li Ke nodded simply.
When driving into the area where the Loess Plateau is located, Li Ke's car navigation also came with an introduction to the front.
"We are about to enter the Huangtu Plateau Nature Reserve ahead. Do you need to introduce the details?"
"Introduction." Li Ke responded directly.
"Okay, the Loess Plateau Nature Reserve was established in the 477th year of the Tang Dynasty, together with the Taklimakan Ecological Nature Reserve, the Qinghai-Tibet Plateau Qiangtang Nature Reserve, the Hoh Xil Nature Reserve, and the Xihanhai Prefecture Grassland Nature Reserve. Six reserves, including the Ili River Aral Sea Nature Reserve and the Kawel-Route Desert Nature Reserve, are among the first batch of seven large-scale first-level nature reserves established by Datang.”
"These seven nature reserves were discovered after many years of research by Datang scholars and are important environmental nodes related to the entire Datang ecological system. Therefore, all grazing, planting, water and soil, and wild animal groups in the reserves have strict regulations. ."
"At present, there are a total of 76 first-level nature reserves in Datang, distributed in various locations in Datang. All nature reserves have a common characteristic, that is, their environmental and ecological systems are very fragile. Once Excessive logging may cause the extinction of a large number of animals and plants, or cause unstoppable ecological deterioration."
"The Loess Plateau Nature Reserve has consciously protected and restored water and soil since the Shengzong era. Although its bottom layer is covered with a large amount of loess, after thousands of years of forest and plant cultivation, the current vegetation coverage of the Loess Plateau has It’s 93 percent.”
"The forest coverage rate has reached 79%. According to the survey and research of the National Forestry and Ecological Protection Department of Datang, the vegetation and forest coverage rate of the Loess Plateau has basically reached the level of the Xia and Zhou Dynasties."
"In this land, which was once the birthplace of Chinese civilization, after more than a thousand years of forest and vegetation growth, a large amount of humus has begun to accumulate in the surface loess."
"Although it may not be able to form black soil similar to the two most important black soil plains in the Tang Dynasty, it has been determined that the humus on the Loess Plateau is already being excess and deposited, and the excess humus can breed more plants and vegetation."
"Since one hundred and thirty-two years ago, the Ministry of Forestry and Ecological Protection of Datang announced that human intervention will be suspended in the Loess Plateau Nature Reserve, and the internal vegetation environment will evolve naturally."
"In the foreseeable future, the Huangtu Plateau Nature Reserve will become one of the nature reserves with the richest species in the Tang Dynasty."
As the car and machine were introduced, 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. Li Ke knows very well what the Loess Plateau was like during the founding period of his country.
The entire country did not know how much money it had spent and how many years of planting and restoration it took for the Loess Plateau to reach 63% when Li Ke traveled 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%. At that time, some people evaluated the Loess Plateau as the most unsuitable place for human habitation.
But even if it reaches 63%, the recovery of the Loess Plateau still has a long way to go, especially what the Tang Dynasty has done in this world, and the road to stopping human intervention is even longer.
Many people may think that as soon as trees are planted, vegetation will grow, isn’t it enough? Why continue the continuous investment of human intervention.
That's because the formation of a forest, especially the formation of a natural forest, contains a complete ecosystem of vegetation, while artificially restored vegetation and forests only complete the initial restoration, first preserving soil and water.
The subsequent growth of forests and vegetation will still require intervention, and it will be continuous intervention for many years, because the plant species in the forest must be diversified, otherwise, if left alone, these forests will also die on a large scale.
And if we want to completely abandon human intervention and leave it to natural evolution like the Tang Dynasty, I am afraid it will take at least a hundred years before we can initially let go of human intervention and shift to focused monitoring.
To be honest, Li Ke was a little touched. The forest coverage rate was 93%. In other words, the entire reserve was almost covered by forests and vegetation, and human activities were basically reduced to a minimum.
"Please note that it is strictly prohibited to use fireworks outdoors in any forest when entering the reserve, and it is not allowed to cross the virgin forest without permission. Anyone who crosses without permission will be subject to administrative penalties, fines, and even prison terms."
A warning sound came from the car. Both sides of the highway have turned into dense virgin forests. In order to prevent plants from damaging the highway, some isolation zones of twenty to thirty meters have been built on both sides of the highway.
But it can be seen that the isolation belt is not very effective. Many plants have gradually begun to erode in. Obviously these isolation belts also need long-term manual cleaning. Otherwise, these plants will quickly fill up both sides of the road. .
The location given by this fan was a bit far away. After getting off the highway and driving on a winding mountain road of more than 100 kilometers, Li Ke finally arrived at his destination.
Zhangjiacun.
When Li Ke's car arrived at the entrance of the village, what he saw was such a plaque. The entire village was surrounded by forests. The roads in the village had been hardened, but when Li Ke's car entered the village, he You can see the curiosity in the eyes of the villagers outside.
Driving to the place where the village committee is located, there is a small square here, but there are more than a dozen old people sitting in the square at the moment. Li Ke parked the car on the side of the road and got out of the car.
Instead of asking the assistant to start broadcasting, Li Ke chose to learn about this place by himself.
Seeing the young people coming, these old people were obviously a little curious in their eyes, "Young man, where do you come from?"
An old man with completely white hair asked with a smile.
