On August 23, the value realization of the carbon reduction product value of Saihanba and the credit signing ceremony of financial institutions was held. Twelve companies purchased carbon reduction products from 8 units including Saihanba Machinery Forest Farm, and realized value conversion of 24.6059 million yuan.

Data show that the world's largest artificial forest can fix 860,300 tons of carbon dioxide each year, equivalent to the annual carbon dioxide emissions of Zhonghe 860,000 household fuel cars. The Saihanba Forestry Carbon Exchange Project has successfully filed 4.74 million tons in the National Development and Reform Commission, and conservatively estimated that economic revenue can reach hundreds of millions of yuan.

It is the mission of Saihanba to raise the important achievements that have been struggling for 60 years.

What is the saturation value of forest coverage? The answer is 86%. This means that except for roads, rivers, wetlands, fireproof isolation belts, buildings, etc., all parts of Saihanba will be covered with green.

In order to achieve the saturated value of forest coverage, we must first solve the world -class problem of forestry on the stone yang slope with small soil, steep slope, and difficulty in saving water.

"What is the stone yang slope? You see, there are only five or six centimeters of humus, and all are stones below, which is not conducive to the survival of the seedlings." Gravel.

Yu Shitao is the leader of the R & D leader of the afforestation ecological topic and the deputy chief of the Saihanba Machinery Forest Farm. The difficulty of afforestation exceeds his imagination: "When encountering steep slopes, the machinery and equipment can not go, all rely on manpower to take the tree seedlings one by one, one by one Go up the ground, move your hands and feet with little bit. "

The people of Saihanba are not afraid of hard work and conduct various research tests. The survival rate of trees planted on the stone mountains has reached more than 90%, and "flowers" are opened on the stone. The slope is covered by green little by little.

Forestance pays attention to "three divisions, seven divisions". After the formation of the forest, the management and protection are even more important.

"The main pests in the forest farm are fallen leaf pine caterpillars and fallen leaves. Our task is to prevent pests and protect the safety of forests." "Doctor Forest", Yuan Zhongwei, a forestry from the Sahanba Machinery Forest Forest Camp Forest, Yuan Zhongwei.

In Yuan Zhongwei's impression, the prevention and control of pests in the past mainly relied on artificial spraying agents. He and colleagues often got up at two or three in the morning and rushed to the operating plot, carrying 30 kilograms of potions and equipment, and work when the wind was small before the dawn.

With the continuous application of advanced equipment, the ability to prevent and control the diseased pests in the forest farm has continued to innovate -the use of helicopters and drones has become the norm. Among them, a helicopter can spray 800 kilograms of medicament again, covering 2,000 acres of forest land, and can complete the prevention and control of pests and insect pests in the forest field in two or three days.

"In some places, the woods are dense, the terrain is steep, and people can't get in, and the helicopter can't cover it. We use the drone to sprinkle medicine to prevent and control." Yuan Zhongwei is one of the first batch of drone operators who hold the certificate of the forest farm.

In the past, affected by factors such as high -cold, high altitude, semi -drought, and land desertification, the forest farms were mainly fell in North China, pine pine, camphor pine and spruce. The tree species is relatively single, which is not conducive to insect prevention, fire prevention, and disease prevention.

To this end, the forest farm scientifically allocated tree species, and gradually cultivated forests into mixed, alien, and compound forests, and at the same time introduced some shrubs suitable for local growth under the forest.

"Here there are flowers, ingot maple, and broad -leaved tree species such as white birch, purple leaf thick Li, etc., which are newly planted later." In Shanghai Memorial Lin, Yuan Zhongwei pointed to the tree species around him.

The deserted mountains that used to be "bird -free trees" are becoming a genetic library of animal and plant species: here have 261 species of terrestrial wild vertebrates, 32 fish, 660 species of insects, 179 large fungi, and 625 plants.

Forest protection fire prevention is also inseparable from the "blessing" of technology.

At the Saihanba Machinery Forest Forest Forest Fire Fire Command Center, the large screen of the forest farm fire video surveillance system can see the vast forests and the safety of the forest flowers and trees in real time.

Forest fire technology is constantly updated. Although there are high -tech equipment such as satellite and infrared monitoring, manual adherence is still indispensable.

"Determine the orientation, rotate the compass, adjust the pointer, the number of views, and then measure the distance on the azima diagram to more accurately judge the location of the fire." Since this year, Liu Jun and Wang Juan of the Moon Mountains have added new fire prevention equipment——Cassboard and azimi map, watch the millions of acres of forests together.In the early autumn season, the Saihanba Machinery Forest Farm was full of eyes.Gao Junhu Photo

The dedication of the Saihanba people gets the generous feedback of nature: Compared with the early days of the establishment, the local frost period has increased from 52 days to 64 days, and the annual average annual wind is reduced from 83 days to 53 days.Increasing to 460 mm, the forest ecosystem can provide more than 10 billion yuan of ecological service value each year ...

Secondary entrepreneurship, there is no poverty.The Saihanba people did not meet the achievements that have been achieved. Forest Farm also launched a research topic of the second entrepreneurial development of Saihanba to achieve a virtuous circle of ecological protection, green development and improvement of people's livelihood.Essence
