China News Service, Lanzhou, April 27 (Reporter Feng Zhijun) At the end of April, on the north side of the middle section of the Hexi Corridor and on the edge of the Badain Jaran Desert, various sandy plants with green shoots were gradually extracted, as well as the endless sand-fixing grass squares. The "confrontation" in the deserted desert is full of vitality.
As an important node of local desertification prevention and control for decades, the Populus euphratica forest, which is continuous with this area, has not only become a model of ecological management, but also unexpectedly become the "new landscape" of the Silk Road.
In Jinta County, Jiuquan City, Gansu Province, more than 60% of the area is desertification, which is one of the areas with the most serious desertification and land desertification in Gansu.
Since the 1950s, successive local governments have taken sand control and sand control as a fundamental measure to revitalize the economy.
"Through the national mobilization-style process of sand prevention and control, in the past five or six years, all kinds of sand plants have advanced about 10 kilometers into the depths of the desert." For more than 30 years, Li Yonghua, deputy head of the Jinta County Forest Resources Workstation, has never Intermittently "competing" with the wind and sand, in recent years he has witnessed the yellow sand wearing a little "green" becoming more and more "gentle", and he has also strengthened his confidence and determination to "turn more deserts into oasis".

Every spring, Jinta residents will bring their own dry food, bring seedlings and tools, and flock from all directions to the edges of various deserts, key sandy mouths and Gobi deserts... Li Yonghua told a reporter from Chinanews.com that in the past, the terrible scene of the golden pagoda's yellow sand raging, So far, many residents have been "talking about the color change of sand", so "sand control" is a skill that almost every local has mastered since childhood, so it has also been "passed on" for decades and generations.
However, the average annual rainfall of Jinta is less than 60 mm, and the evaporation is as high as more than 2,500 mm. It really makes every planted sapling survive as scheduled, and the cost is no less than feeding a child.
As a result, the local area actively explores a variety of sand control models to effectively control the process of land desertification.
Among all kinds of sand control plants, red willow and sand jujube trees are the most selected sand-fixing seedlings.
A staff member of Jinta County said that the red willow with strong sand-fixing effect will have two flowering seasons every year, and the pink or rose-red flowers spread along both sides of the road will become a unique landscape corridor.
The sand jujube tree, which is resistant to wind and sand, salt and alkali, and barrenness, can be described as a treasure. Every May and June, the air is filled with the fragrance of jujube flowers. The edible jujube is also developed by the local people. Various types of regional specialties .
In addition to continuously exploring various innovative desertification prevention and control technologies according to local conditions, how to take into account the economic benefits and "rushing for gold from the sand sea" has also been taken into account in the local ecological management.
According to Wei Cai, deputy director of Jinta County Natural Resources Bureau, in recent years, Jinta has also vigorously promoted industrial sand control, using mobile sand dunes to make building materials, and planning and building a building materials industry in the hinterland of the Baishui Spring Sand System, where sand damage is serious. There are more than 10 "sand-eating" enterprises in the park, with an annual output of 350,000 cubic meters of autoclaved aerated blocks, 150 million gray bricks, and 400,000 cubic meters of commercial concrete, with an annual consumption of 500,000 cubic meters of quicksand.

In recent years, "Eupulus euphratica Ecotourism" has become a famous Silk Road tourism business card in the northwest and even the whole country, which is regarded as a model of local ecological construction.
But more than 40 years ago, there were still bare deserts everywhere. With the strong wind, the sand dunes "run" to the county town with the wind.
"At that time, in order to resist the hazard of wind and sand that covered the sky and the sun, we planted Populus euphratica on a large scale with strong vitality and good sand-fixing effect. A longing tourist destination." As a sand control person who participated in the planting of Populus euphratica earlier this year, Wang Duanzheng, the 67-year-old former deputy director of the Populus euphratica forest farm in Jinta County, was immersed in sighing for a long time after comparing the changes between the past and the present.
Jinta County officials said that following the launch of the "Co-planting Populus euphratica and sharing green" public welfare action in recent years, the local area will also actively strive for Huawei's public welfare afforestation project and China Green Foundation's Ant Forest public welfare afforestation project this year, focusing on the management of key sandstorms and desertified land, and continue to strive for sustainable development. Consolidate and strengthen the achievements of desertification prevention and control.
