See how afforestation and greening (green homes)
"The sun and the rivers are beautiful, and the spring breezes and flowers are fragrant." The green season is constantly spreading in the land of China.
At present, China's forest coverage rate has increased from 12.7% in the early 1970s to 22.96%. The forest area and stock volume have maintained "double growth" for more than 30 years, making important contributions to coping with climate change and promoting global ecological governance.
General Secretary Xi Jinping emphasized that when he participated in the voluntary tree planting activity in the capital on April 3, the idea of firmly establishing green water and green mountains is the concept of Jinshan and Yinshan, strengthening ecological protection and restoration, expanding urban and rural green spaces, planting trees and forests for the people, and working hard to build green mountains. Beautiful China with long flowing green water and fresh air.
All localities are working hard to expand urban and rural green spaces and deepen the greening of the country. In Minqin, Gansu, afforestation plots and scales are determined according to water resources carrying capacity; in Xiong’an New District, Hebei, advanced “near-natural afforestation” methods allow individual growth and natural succession of trees; in all parts of Zhejiang, land greening is accelerating The green that is always present in the Jiangnan season will be more touching ... Focusing on both "expanding green" and "improving quality", we will usher in a beautiful green and vibrant China!
Gansu Minqin adapts to local conditions, adapts trees to suitable sites, and sets forests by water
Wind sand line builds a great green wall
Our reporter Wang Jintao
In Minqin County, Wuwei, Gansu Province, above the sand dunes are clusters of haloxylon forests, and Wei Runhong, a farmer in Dongrong Village, Zhongqu Town, is working with a shovel in his hand. He has been afforestation in this area for 16 years.
This is the Qingtu Lake area, sandwiched between Badain Jaran, the third largest desert in China, and Tengger, the fourth largest desert in China. "Qingtu Lake is the largest aeolian sand mouth in the northern part of Minqin Oasis. The aeolian sand line is 13 kilometers long and the sand area is 120,000 mu. The two deserts are encircling here." Tao Haixuan, head of the forest farm of Sanjiao City in Minqin County, said.
"In the past, the wind blew up the sand, and the cropland became a sand nest in the night." Wei Runhong said, the sand dunes blocked the road, and no one could go out, "Old people said that our children were born in the sand, our The destination is also in the sand. "
As one of the sources of sandstorms in China, the wind and sand line in Minqin is 408 kilometers long. In 2009, the desertification area of the county reached 94.5%. The poor natural environment has caused some Minqin people to be forced back by wind and sand. "There is a group in our village, and there is only one household left." Wei Runhong said.
"Never let Minqin become the second Lop Nur! But it can't be stubborn to fight against the wind and sand. Minqin's annual precipitation is only more than 100 millimeters, but the evaporation is as high as more than 2000 millimeters. The east, west and north are surrounded by desert." Jinqin Wan, director of the Minqin County Forestry and Grassland Bureau, said that Minqin decides the scale of ecological construction according to the water resource carrying capacity, insists on suitable sites and trees, promotes the use of local good varieties and strong seedlings. Continuously improve the quality of afforestation.
"We actively carry out technical exchanges and cooperation with scientific research institutions, colleges and universities, etc., in areas such as Qingtu Lake and Changsha Xishawo, to explore and carry out afforestation experiments with new materials such as water retention agents and anti-seepage sand." Jinfa Wan introduced, in Xisha, Changning In the nest area, the "sand pressing afforestation + sprinkler irrigation" model experiment was carried out, and 2000 acres of sand control and afforestation were completed, effectively saving water resources and improving the coverage of forest and grass vegetation. In the daily sand-pressing afforestation project, straight-pipe insertion deep irrigation technology is adopted to prevent waste water from overflowing and causing waste of water resources, and to promote the connection of irrigation water and dry sand layer to the lower water layer, to ensure the good growth of new plant seedling root system and improve afforestation Survival rate.
"At the same time, the local area has increased the proportion of ecological water distribution year by year, and the cumulative amount of ecological water discharged into Qingtu Lake is 280 million cubic meters." Jinfa Wan said that Qingtu Lake, which has dried up for more than half a century, now has blue waves. group. "As of now, 143,000 acres of silt afforestation and 28,000 acres of afforestation have been completed in the Qingtu Lake area. In the past, the deserted land where the quicksands raged has become full of vitality, and the vegetative and vegetative reeds have increased to 41 %the above."
During the afforestation season, Wei Runhong and the members of the sand control team traveled together in the Tengger Desert. They set up tents and used the straw and shuttle to cover the yellow Tengger Desert with green clothes day after day. "In the past, the sand control model of a donkey cart pulling water, a person, a shovel, and a rack truck was a piecemeal." Wei Runhong said that now it is a large-scale, engineering sand control and afforestation.
Today, Minqin County has an area of more than 2.29 million mu of afforestation. On the sandstorm line, a protective forest belt of more than 300 kilometers has been built. The forest coverage rate of the county has increased from 3% in the 1950s to 17.9%. The large sandstorms such as Qingtu Lake, Laohukou, Xida River, and Longwang Temple have been effectively managed, successfully preventing the two major deserts, Tengger and Badain Jaran, from closing together.
Hebei Xiong'an New District will plant 100,000 mu of trees this year
"Near nature" builds a thousand-year-old forest
Our reporter Shi Ziqiang
Workers are busy carrying out tree planting in spring in Beihezhao Village, Bayu Township, Rongcheng County, Xiong'an New District, Hebei. Newly planted saplings such as Pinus sylvestris, Cotinus coggygria, and ash are scattered, and are planted in a special mixed way.
Peng Xu, deputy general manager of China Xiong'an Group Ecological Construction Company, also introduced that, unlike general afforestation, Xiong'an afforestation practices the concept of "near-natural afforestation". What is "near nature"? "It is to follow the principle of" respecting nature, conforming to nature, protecting nature ", maximally simulating the environment in which forests grow in nature, and through the necessary manual intervention, allow trees to achieve individual growth, natural succession, and make forests close to natural forest In the natural forest. "
The Daqinghe Forest in Xiong'an New District is the first near-natural forest planted in 2017, and it will become the urban central forest park in the new district.
The reporter saw that the trees in the forest are very rich, including Pinus tabulaeformis, Pinus tabulaeformis, Ginkgo biloba, and Pagoda tree. On the top, it is natural random placement, "disordered" planting.
"When these trees were planted, there were two years of seedlings and many years of seedlings; the tree had a small breast diameter of 3 centimeters and a large one of 8 centimeters; the height of the tree was two to three meters short and the height was 10 meters. Create a kind of near-natural forest of different ages, multiple layers, mixed. "Peng Xu even said.
Since its establishment, Xiong'an New District has adhered to ecological priority and green development, and proposed to build a "millennial show forest" worthy of the "millennium plan and national events".
"Thousand-year-old Xiulin, not to say that every tree can live for 1,000 years, but through nurture and management of near-natural forests, to promote their strong self-renewal and self-succession ability, forming a vitality and inclusiveness Extremely strong ecosystem, "Peng Xu even said," Thousand-year-old Xiulin and human society have many similarities. The life span of a tree may be only a few decades, but the natural succession of "trees and grandchildren" can continue Breeding to give the forest a long life and vitality. "
The "near-natural afforestation" of Xiong'an New District also has strict standards and clear requirements in the selection of saplings. It is better to select high-quality native crown seedlings rather than artificially cut-off seedlings. The purpose is to respect the nature of seedlings and to be as close to nature and original ecology as possible. At the same time, in order to improve the survival rate, priority is given to the use of native trees and local seedlings with strong resistance; the millennium show forest technical standards are formulated to standardize every operation process of afforestation.
At present, Xiong'an near natural forests represented by Daqinghe forests are growing well. Ginkgo, Guohuai, Fatong and other trees have grown about 3 to 5 centimeters thick, and Chinese pine and other trees have grown about 1 meter tall. Rich and mixed tree species enhance the ability to resist pests and diseases and form an excellent ecological environment. Peach, pear, cherry blossom, begonia, etc. provide food and honey sources, making small animals such as hares, hedgehogs, and birds such as pheasants more and more Appear in many places in the forest.
From 2017 to the end of 2019, more than 300,000 mu of new forests were planted in Xiong'an New District, with more than 200 tree species. Xiong'an New District will add 100,000 mu of afforestation this year. Hebei Province plans to afforest 5 million mu this year, distributed in Xiong'an, Taihang Mountain, Yanshan and other regions.
Zhejiang plans to add more than 1.8 million mu of afforestation in 5 years
Tree planting is more important than quantity

"The pits are dug deeper so that the tree roots can stretch ..." Forester Ye Falin digs the soil while instructing everyone to plant trees while Cheng Jiayuan Village, Zitong Town, Chun'an County, Zhejiang Province. Since the beginning of spring, Chun'an County has seized the golden season for tree planting. Up to now, 10,800 acres of new afforestation have been completed, accounting for 92.3% of the annual plan.
According to the climatic conditions of Zhejiang, the season for afforestation is in February. During the prevention and control of the new coronary pneumonia epidemic, the progress of planting trees in many places lags behind. On one side, the epidemic prevention and control cannot be loosened; on the other side, the timing of greening does not wait for others. How to complete the afforestation task on time and with high quality?
Epidemic prevention and control and afforestation "two hands"! The forestry department of Zhejiang Province has paid close attention to completing the preliminary work such as plot implementation, operation design, and seedling preparation; in various cities and counties, wall charting operations and closed-loop management are carried out to promote afforestation and greening.
In an abandoned mining area in Miaoxi Town, Wuxing District, Huzhou City, more than 100 government officials and volunteers are carrying out tree planting activities here. In half a day, more than 200 red photinia seedlings were planted. The mining area used to be "grey on a sunny day and mud on a rainy day", but now it has returned to green. Huzhou has stepped up afforestation to spread more green on the ground.
Some people used shovels to shovel the soil, some people used buckets to irrigate ... In Longyou County, Quzhou City, a tree planting team of more than 80 people composed of cadres and volunteers came to Jiangjia Village, Zhanjia Town to carry out voluntary tree planting. In a day's time, more than 500 plants such as Mountain Cherry and Nan Nan were planted.
As of March 23, Zhejiang Province has completed 248,900 mu of artificial afforestation, nearly three times the same period in the previous year. More than 1.26 million people have participated in voluntary tree planting activities, and more than 7.65 million trees have been planted.
Zhejiang not only values the quantity of afforestation, but also the quality of afforestation.
Adhere to the national greening work as a "top leader" project. In Lishui, the city implements the four major guarantees of policy, land use, seedlings, and services, and clearly draws a certain percentage of funds from the land transfer funds for greening fund protection. At the same time, all districts and counties strengthened technical service support. Liandu District conducts online and offline training to guide afforestation matters; Longquan City vigorously promotes afforestation information management, uses drone broadcast, and simulates natural flying particles to land into forests.
Combine land and greening work with economic industry. Chun'an County has built "forest trees + Chinese herbal medicines" into an efficient ecological restoration industry. Fang Yang, director of the Chunan County Forestry Bureau, said: "Under the forest space cannot be wasted. When we plant under-forest Chinese medicinal materials, we not only spur the villagers' money bags, but also improve the quality of the forest land and the ability to retain water and protect soil.
Scientifically doing a good job of land and greening, while Zhejiang has greened the mountains and rivers, it has also brought a comfortable life to the people. In Hengkeng Village, Fengshuling Town, Chun'an County, villager Liu Genyue told reporters: "In the past, the corners of the village were full of weeds. In the summer, mosquitoes are scary. Now they are planted with Taxus chinensis. There is someone to maintain it. The mosquitoes are obviously fewer, and life is more comfortable. "
Spring flowers, summer shades, autumn colors, winter rhymes ... Zhejiang, which vigorously promotes the greening of the country, is green all year round, and the "face value" of the earth is constantly improving. According to the "Zhejiang Province's Action Plan for Adding One Million Mu of Land and Greening (2020-2024)", by 2024, Zhejiang Province plans to add more than 1.8 million mu of afforestation, with a forest coverage rate of more than 60%, and basically establish a reasonable layout and coverage Urban-rural, powerful forest ecosystem.
