        In recent years, Jiayuguan City has relayed the national voluntary tree planting activities, actively promoted large-scale land greening actions, focused on improving the management and protection level of landscaping, and continuously improved the urban and rural living environment. The greening work of the city has achieved remarkable results. By 2020, the city's forest area has reached 15216 hectares and the forest coverage rate has reached 12.5%, successfully completing the objectives and tasks set in the 13th five year plan.

        When the reporter drove more than 20 kilometers to the construction site of irrigation water source project of forest vegetation restoration and artificial afforestation project, the constructors were binding floor reinforcement and directing the pump truck to pour concrete, which was a hot construction scene.
        "This is the largest ecological construction project in Jiayuguan, with an afforestation area of 5606.5 mu, equivalent to two East lakes..." said Wang Lihong, deputy director of the municipal forestry and grass Bureau. She told reporters that the total investment in the preliminary design estimate of the project is 67.8888 million yuan, including 29.5766 million yuan for afforestation project and 38.3122 million yuan for irrigation water source project. The project is located 20km north of Jiayuguan City. The project area is located in the north of the Great Wall site, the south of x253 Road, the west of one trunk and one branch canal in Taolai Hebei and the east of Ceke railway.
        In many places, planting trees is to dig a pit and plant seedlings. It's very easy. But in Jiayuguan, which is located in the Gobi desert, it is too difficult and too bitter! Planting a tree is more difficult than raising a child! Sandstorm, saline alkali and drought are serious, with an annual precipitation of 88.4 mm and an annual evaporation of 2000 mm.

        Wang Lihong told reporters that in order to solve the problem of irrigation water source in the planting area, the project will draw the reclaimed water produced by the sewage management office of our city for forest land irrigation, deliver water to the new 800000m3 regulation and storage tank through the new 2.6km DN600 pressurized ductile iron pipe, and build supporting facilities such as water intake, water lifting pump station and forebay, water outlet and vent gate and discharge pipeline.
        Planting trees and changing soil on the Gobi desert is also a big problem. "We must first remove the stones in the Gobi desert, and then fill the soil before planting trees. It is conceivable that the amount of work." pan genqiang, manager of Jiayuguan lvrong Construction Investment Co., Ltd., the construction unit of the project, told reporters. He told reporters that in order to effectively improve the urban rural living environment and repair the ecological environment system, the forest species of the project are windbreak and sand fixation forests, and the tree species are mainly sandy vegetation, including red willow, Caragana, seabuckthorn, Populus euphratica, Elaeagnus angustifolia, Amorpha fruticosa, flower stick, four Seasons rose, etc.
        "We will also build a 45 Mu sandy vegetation exhibition area, which will be designed and planted according to biological classification to display the sandy vegetation in a centralized way," pan genqiang said.
        Whether in terms of afforestation area or the number of trees planted, it can be called a vast forest. Forest is the most important security barrier in terrestrial ecosystem, which is called "lung of the earth". With this barrier, people living in this city will not be surrounded by desolation. It is precisely because of this barrier that it will bring a variety of ecological service values to our city, such as water conservation, water and soil conservation, improvement of environmental quality, biodiversity maintenance and so on.

        The citizens of Jiayuguan have turned their green desire into green action in exchange for green hope. "The whole project will be completed in October 2023," said Fu Ruibo, chief of the urban landscape section of the municipal forestry and grass Bureau.
        Fu Ruibo told reporters that the water supply pipeline project of the project started on July 22. Up to now, 26865.58 meters of all pipelines have been installed, pressurized, backfilled and built 174 inspection wells, with the completion proportion of 85%; The artificial afforestation project was started on September 3. Up to now, the site leveling, sand and gravel excavation and backfilling of 31985.6m3, maintenance and management Road (pavement leveling) of 20300m, micro terrain earthwork of 18715m3, production of 169 sets of water distribution tanks and tree cave excavation of 27203 have been completed, with a proportion of 65%; The irrigation water source project was started on September 3. Up to now, 10584m3 of sand gravel excavation of diversion pipeline has been completed, accounting for 54.5% of the total; The pipe trench is padded with sand for 800m, accounting for 29.8% of the total; The connection of ball milled cast iron pipe is 600m, accounting for 21.6% of the total; The excavation of sand and gravel in the forebay of the pump station and the excavation of sand and gravel in the main power house of the pump station have been completed; 1370m3 (83570) C25 precast blocks have been completed, accounting for 42% of the total.
