Spring blossoms, everything recovers, and the season of planting trees! Remember the days when I was taken by the teacher to plant trees in the mountains when I was young? It was a childhood memory to plant a tree by hand. The memory grows and gathers and becomes a lush forest. In recent years, China's annual afforestation area has exceeded 7 million hectares. NASA data shows that from 2000 to 2017, China's net growth in green leaf area and net growth rate ranked first in the world, the biggest contribution comes from afforestation.
China has turned green a little bit, benefiting from the tree planting of the whole people and the contribution of the national afforestation project. These projects include the well-returned returning farmland to forests, the “Three Norths” and the key protection forests in the middle and lower reaches of the Yangtze River.
Afforestation, China really turns green
According to a study released by NASA (National Aeronautics and Space Administration) in February this year, the area of green leaf added by the earth (the total area of plant leaves) is equivalent to an extra Amazon rainforest from 2000 to 2017. Among them, the net growth rate is the highest. It is China (17.8%), followed by India (11.1%) and the European Union (7.78%).

The deeper the green, the higher the growth rate, the brown color represents the negative growth state, the white is the unmanned area, the permanent frozen area, the permanent wetland and the urban built-up area, and the blue is the water cover area such as the ocean. .
The largest net increase in green leaf area is China, which is 1.351 million square kilometers, which is almost the sum of the net growth areas of Russia, the United States and Canada.
China's net growth area of green leaves accounts for 25% of the global net growth area of green leaves, with 42% of its contribution coming from afforestation projects and 32% from agricultural intensification. In these two areas, the European Union is 34% and 55%, India 4.4% and 82%, respectively.
It is estimated that the afforestation project in China has brought 10.5% (25% ≤ 42%) of the net growth area of green leaves in the world. As soon as the data came out, since the media came out, "netizens all over the world suddenly thanked China collectively." netizens all over the world are saying thank you to China, "and they are busy with netizens all over the world.
National forestry engineering is the real "thigh"
Chinese netizens are also excited, and they have shown their achievements in the tree planting activities. Indeed, in recent years, various social welfare activities and public welfare organizations have emerged, and more and more people are participating in tree planting activities.
However, China is turning green a little bit, of course, thanks not only to the planting of trees by the whole people, but also to the contribution of the national afforestation project, which is the real "thigh" of afforestation.
These real "thigh" projects include the well-returned project of returning farmland to forests, the "Three North" and the middle and lower reaches of the Yangtze River, such as key protection forest projects, natural forest protection projects, and sand control projects in Beijing. The data shows that the total area of afforestation in China from 2004 to 2017 was 82.085 million hectares, of which 41.72 million hectares of forestry were completed, accounting for 50.8% of the total afforestation area; the forestry key project completed the largest afforestation area, nearly 15.46 million The hectare is followed by the protection forest construction projects in the Three North and Yangtze River basins, with afforestation area of nearly 11.55 million hectares; again the natural forest protection work, the afforestation area is more than 8.27 million hectares; the Beijing-Tianjin sand source control project afforestation area ranks fourth, afforestation area Nearly 6.33 million hectares.
From the map published by NASA, we can clearly see that China has a green oil-filled sling, which is basically consistent with the location of the Three-North Shelterbelt Project, and constitutes the ecological Great Wall of China. In addition, the scope of the shelter forest system in the middle and upper reaches of the Yangtze River is also “spring breeze and green river south + river north bank”.

In addition to these real "thigh" projects, there are some local governments, organized greening and afforestation projects, such as Beijing, Inner Mongolia and other places have local greening projects. Social forces are actively involved in greening public welfare activities, a variety of social public welfare activities, public welfare organizations continue to emerge, committed to environmental protection. For example, the China Greening Foundation launched social forces in 2018, planting 57.186 million trees and covering an area of about 52000 hectares.
Compared with the national key forestry projects, the area of planting trees from the social public welfare forces can be ignored. China is able to green, and the biggest contribution comes from these real``thigh'' projects. Of course, although there are not many trees for social public welfare afforestation, the significance is much greater than this. It is to close the distance between the individual and tree-planting activities, which enhances the user's participation in the public welfare activities of afforestation.
Although China is turning green little by little with the contribution of the national afforestation project and the planting of trees by the whole people, China's environmental protection still has a long way to go, and there is a long way to go. Let's plant trees together! You can contact local compulsory tree planting points to participate in tree planting labor; you can adopt trees such as Platycladus orientalis, Sabina juniper, Robinia pseudoacacia, Ginkgo biloba and so on through tree adoption reception points; you can raise labor through social care labor reception points, participate in watering, whitening, weeding, green space cleaning and so on; you can donate money and donations to legitimate public offering organizations to donate funds for land greening; May also participate in land greening public welfare publicity activities, or according to the relevant requirements to provide popularization and promotion related to land greening, training guidance, public welfare activities organization and management and other voluntary services.
