See a set of data: At present, my country's plantation area is the world's largest, contributing about 1/4 of the new greening area in the world. We all have so many trees, why do we still have to plant trees every year?

——People's Daily Netizen 18****6

This netizen is very concerned about ecological issues, which itself shows that the concept of ecological civilization has entered people's hearts.

At the end of last year, news that the Taklamakan Desert was tied with a "green scarf" flooded the screen. How hard does Chinese people work to plant green and control sand? There is a more concrete answer.

Over the years, we have insisted on planting trees and have achieved remarkable results. The world has the largest growth in forest resources and the largest plantation area, and the forest area and stock volume continue to "double growth"...

With such achievements, no wonder netizens are confused.

When planting trees and afforestation, we really can't "lie down". Why do you say so? Understanding from 3 perspectives -

First of all, the area of ​​artificial forests is the first, which does not mean that forest resources are rich, and the problem of lack of forests and greening in my country is still prominent.

Look at the total amount first. Although our forest coverage rate has exceeded 25%, more than double the 12% in 1981, there is still a gap compared to the global average of 31%; the per capita forest area is only about 30% of the world average. my country's foreign dependence on wood is at a high level of about 50% for a long time.

Look at the distribution again. Affected by climatic conditions and geographical environment, my country's forest resources are mainly concentrated in the northeast and south. The northwest has drought and little rain, and water resources are short of water, making greening difficult, costly and long cycles.

Secondly, the "size" of the plantation has existed, but there is still a lot of room for strengthening the "physical constitution".

Share two concepts: "natural forest" and "plantation forest" - these are the two main types of forests in our country. Natural forests are naturally formed, rich in biodiversity and strong ecosystem stability; plantations are forests formed through artificial measures, which grow fast and are easy to develop.

However, due to historical reasons, my country's natural forests were once over-defortified, and the forest regeneration capacity was "significantly damaged". In order to pursue rapid growth and high yields, most of the plantations that have been added on a large scale are single tree species, which have weak ability to resist natural disasters, and need to improve the quality through means such as adjusting the structure of forest stands and replanting precious local tree species.

Third, planting trees and afforestation not only planted saplings, but also development advantages and potential.

How valuable is a tree or a forest?

Forests are the main body of terrestrial ecology and the foundation of human survival. In addition to purifying the air, maintaining water and soil, preventing wind and sand, forests also combine reservoirs, grain storage, money storage, and carbon storage, which is an absolute treasure house.

Green water and green mountains are gold and silver mountains. Relying on the forest treasure house, the annual output value of our four pillar industries, namely wood and bamboo processing, forest food, forest economy, and ecological tourism, has exceeded one trillion yuan. In addition, the annual carbon sink of forests and grasslands also exceeds 1.2 billion tons of carbon dioxide equivalent, ranking first in the world. With beautiful ecology, prosperous industries and rich people, we must make this mountain of gold and silver even bigger in the future.

Planting trees to increase greening and improving ecology, everyone is a beneficiary, the benefits are in the present and in the future. The key is to continue planting trees and plant green scientifically, and to manage both quantity and quality, and to focus on the incremental stocks.

So, how should this tree be planted?

The “main direction” of greening is different in different regions. If the ecology of the Three Norths is fragile, it is necessary to expand the scope and increase greening scientifically and build a solid ecological barrier. Where forest coverage is high, change your concept and adjust the structure and improve the quality of the stock. Cities with "every inch of land are valuable" and "stood for every inch of land" should "stood for every opportunity" and "demolition of enclosures to make up for green", and use "micro transformation" to optimize the living environment.

National land greening is a national "big project" and cannot be separated from each of us.

Planting trees and protecting forests is a citizen’s obligation to be written into the Forest Law. The voluntary tree planting campaign has been carried out for more than 40 years, and the form of responsibility has expanded to more than 50 categories. It can not only "directly participate in afforestation and greening", but also "indirectly fulfill tree planting obligations" through recognition of seeds and breeding, donating funds and materials.

"Don't have time to plant?" "I don't know which kind to go?" The Internet empowers, "doing responsibility on code" and "planting trees in the cloud" are convenient and smooth. The forestry and grassland department strengthens management and strives to ensure that one plant can live and one plant can be made into one.

"Source one after another, and work one after another." The continuous thickening of the "green family foundation" has accumulated enough momentum for development; the ecological space with beautiful mountains and rivers has built blessings for descendants.
