China has completed eighty percent of this year s afforestation task, what is the positive effect on

According to the People's ** report, the reporter learned from the State Forestry and Grassland Administration: as of the end of September, the country has completed afforestation of 79.64 million mu, accounting for 79% of the annual afforestation target. The National Forestry and Grassland Administration recently held a first-class meeting to organize all localities to summarize and exchange experiences and practices in coordinating epidemic prevention and control and orderly carrying out afforestation and greening, and deploy and promote afforestation and greening in autumn and winter.

The most direct benefit of afforestation is that it is conducive to purifying the air, and plants can consume carbon dioxide, release oxygen, and sulfur dioxide gas in the air for photosynthesis, so plants are essential for human survival. <>

At the same time, afforestation has a huge effect on improving China's ecological environment, a reduction of soil erosion: afforestation is the most effective measure to reduce soil erosion, can control land desertification, can increase the water storage capacity of the soil, is conducive to the growth of microorganisms in the soil to keep the soil active, and afforestation is also conducive to reducing landslides, tree growth will make the soil structure more stable. Second, wind and sand resistance:

The great northwest, which was once full of yellow sand, has effectively improved the ecological environment through the efforts of generations of people to plant trees, and is also conducive to changing the soil structure, reducing wind and sand, and also playing the role of shelter forests to block the wind. Third, to promote the development of economic construction, good environmental conditions can attract more business opportunities, and a livable environment will also attract more foreign population, which is conducive to promoting economic development. For example, Longnan City, Gansu Province, which is known as Longshang Jiangnan, has complex topography, three-dimensional and diverse climate, less cultivated land and more slopes, and has developed characteristic forest and fruit industry according to local conditions, which has not only improved the environment but also developed the regional economy, and improved the quality of life of the masses in many aspects.

Fourth, adjust the climate, now global warming leads to the impermanence of climate change in the four seasons, afforestation can play a role in regulating the climate to a certain extent. <>

<> under the influence of the epidemic this year, China has completed eighty percent of the annual tree planting plan, which is related to the active cooperation of various cities, indicating that all parts of China attach importance to afforestation and recognize its important role. The relevant person in charge of the National Forestry and Grassland Administration said that it is necessary to further promote the voluntary planting of trees, prepare for the 40th anniversary of voluntary tree planting, and promote the formation of a diversified afforestation and greening pattern led by the whole people and participated by the society. Therefore, each of us should establish the awareness of actively planting trees and protecting the ecological environment, and take the socialist road of green development.

Afforestation is the top priority of environmental protection, and the strict implementation of afforestation tasks will effectively improve China's ecological environment, make environmental protection planning orderly and make environmental protection measures and experience be effectively fed back and accumulated. The National Forestry and Grassland Administration recently announced that China has completed eighty percent of this year's afforestation task, which is a gratifying thing. First of all, this shows that China's environmental protection has been going on, has been seriously implemented, and has been subject to the supervision and guidance of the public.

As the ecological environment becomes more and more fragile, China's environmental protection plan is related to the long-term development of the country and the people. <>

First of all, the orderly implementation of afforestation tasks can directly improve the ecological appearance of some areas. For example, the northwest region of China urgently needs shelterbelts to resist sandstorms, and urgently needs to form a good ecological foundation, so as to facilitate further environmental transformation. Therefore, the completion of 80% this year will significantly improve the air, soil, animal and plant ecology of each afforestation area to a certain extent.

Secondly, the implementation of afforestation tasks as planned has a certain role in promoting China's environmental protection policies and systems. In the past, the reason why China's environmental protection has not formed a significant effect is that the supervision and implementation of policies and systems are not in place, and the current step-by-step development will allow the first departments and enterprises at all levels to form a perfect system. Higher-level departments can control and guide the overall situation from the completion of afforestation tasks in various localities, reward and promote experience for advanced departments, supervise and urge inactive departments, and feedback and timely solve some actual situations.

Once the regulatory system is formed, it will be gradually updated and improved, so that China's environmental protection can be scientific, systematic and comprehensive. <>

Finally, the task of afforestation does not mean that the task can be completed by planting trees, and there are also particularities in this. In the process, we have also accumulated a lot of experience, which is very practical in practice, such as how to plan afforestation areas, how to overcome the harsh environment to keep the saplings alive, etc. This will also provide a valuable reference for the further improvement of China's afforestation tasks in the future.

I believe that it can absorb harmful gases and reduce noise, prevent soil erosion, afforestation can prevent wind and sand fixation, afforestation can reduce air pollution, beautify the environment, and afforestation can provide many valuable resources for human beings.

The positive effect on China's environment is, of course, to maintain China's environment, to ensure that soil and water are not eroded, to maintain the local ecological environment, and to maintain a long-term development.

Nationwide Voluntary Tree Planting Campaign.

The nationwide voluntary tree-planting campaign has strongly promoted the improvement of China's ecological situation. In 1981, before the campaign began, China had a forest area of 100 million mu, a standing tree stock of 100 million cubic meters, and a forest coverage rate of 12%.

After years of unremitting struggle, China's forest area has reached 100 million mu, the volume of standing trees has reached 100 million cubic meters, and the forest coverage rate has increased to.

In the face of the world's declining forest resources, China has achieved continuous growth of forest resources. The improvement of forest vegetation not only beautifies homes, reduces the harm of soil erosion and sandstorm to farmland, but also effectively improves the carbon storage capacity of forest ecosystems.

Extended information: 1. Maintain water and soil.

Afforestation, returning farmland to forest, and ecological reconstruction are extremely important. Afforestation can conserve water and soil, **vegetation coverage is low, **every rainy season, there will be a large amount of sediment into the river, destroying the fields, filling up the riverbed, silting up the estuary, and causing great harm.

To curb soil erosion, it is necessary to plant trees, because trees have a root system as large as a canopy and can hold on to the soil like giant hands. The water of the soil that is caught is constantly absorbed and stored by the tree roots.

According to statistics, one acre of forest stores about 20 tons more water than non-forested areas. Afforestation can greatly improve the ecological environment and reduce the loss of flood disasters by controlling desertified cultivated land, controlling soil erosion, preventing wind and fixing sand, and increasing soil water storage capacity.

Moreover, as the economic forest has entered the maturity stage, the direct and indirect economic benefits generated are huge, and it can also provide a large number of labor and employment opportunities and promote the sustainable development of the local economy.

2. Resist wind and sand.

Afforestation can prevent wind and fix sand. Wherever the wind and sand go, the countryside will be buried, and the city will be reduced to ruins. To resist the attack of wind and sand, it is necessary to create shelterbelts to weaken the force of the wind.

Once the wind hits the shelterbelt, the speed should be reduced by 70% to 80%. If you arrange many forest belts in parallel at a certain distance and plant grass, then the amount of sand and gravel that can be blown by the wind will be reduced.

3. Economic construction.

Afforestation can provide many useful things to human beings. Many fruits and medicinal herbs are forest products; Tea, rubber, new carbon, etc., are all contributions from trees. The use of the woods is really great.

In the past 30 years, what have been the achievements of China's afforestation activities? In the past 30 years, China's forest Buddha has been more and more green for Lili, especially the shelter forest in the northwest and the shelter forest in the desert, more and more, and great results have been achieved, and the weather of killing people is becoming less and less, for example, the Mu Us Desert is planting trees and controlling sand, and now the Mu Us Desert is about to disappear from the map, and most of them have been covered by green plants.

The important achievement is the Three-North Shelterbelt, which was built in 1978 and is located in the northwest, north of North China and the western part of Northeast China, an ecological construction project of unprecedented scale, known as the "Green Great Wall Construction Project". At present, 22,106 hectares have been planted in this project, which is equivalent to 1,7 hectares of the world's planted forest area.

The Three-North Shelterbelt has effectively curbed local sandstorms, and compared with 1999, the desertified land has decreased by 7,921 square kilometers. The two major sandy lands of Mu Us and Horqin, which are the focus of treatment, have achieved a fundamental transformation and have entered a new stage of transformation and utilization of deserts. Xinjiang has completed afforestation of 2.74 million hectares, and the area of oases has expanded from more than 40,000 square kilometers before the construction of the project to more than 70,000 square kilometers. In addition, the soil erosion in local areas has been effectively controlled, and the key treatment of the Loess Plateau has been afforested by 10,000 hectares, and the area of soil erosion has been newly controlled by 150,000 square kilometers, so that the area of soil erosion on the Loess Plateau has reached more than 230,000 square kilometers, and nearly 50% of the soil erosion area has been treated to varying degrees, the area of soil erosion has been reduced by more than 20,000 square kilometers, the soil erosion modulus has dropped significantly, and the amount of sediment entering the Loess Plateau has been reduced by more than 300 million tons per year.

There are too many, for example, the planting of trees in the Mu Us Desert, and now the Mu Us Desert is almost disappearing from the map, and most of it has been covered with greenery.

In the past 30 years, China's afforestation has turned more desertified areas into green spaces. Now there are fewer and fewer sandstorms in the country, and the air is getting better and better, which is the result of afforestation.

Trees have been planted in many parts of the north, and the results are still gratifying.

China's forest Buddha is more and more green for the benefit of the Buddha, especially the shelter forest in the northwest and the shelter forest of the desert, more and more, and has achieved great results, the weather of killing people is getting less and less, for example, the Mu Us Desert is planting trees and controlling sand, and now the Mu Us Desert is about to disappear from the map, most of which have been covered by green plants.

In the past 30 years, the biggest achievement of China's afforestation activities is that the forest coverage rate has increased from 15% to the current level. The ecological environment of the primeval forest has been greatly improved, the population of wild animals is growing day by day, and the species and quantity of wild plants have increased unprecedentedly.

An important achievement is the Three-North Shelterbelt.

The "Three Norths" shelterbelt is an ecological construction project of unprecedented scale that has attracted worldwide attention and is located in the northwest, northern north and western northeast China, which was built in 1978 and is known as the "Green Great Wall Construction Project". At present, 22,106 hectares have been planted in this project, which is equivalent to 1,7 hectares of the world's planted forest area.

The role of afforestation in protecting the environment does not include ( )aWind and sand fixation BRegulate the climate cMaintain the balance of carbon dioxide and oxygen in the atmosphereProvide enough timber for answer d

The lush forests that cover the earth are a huge and most precious "green wealth" possessed by nature, and the forests are the homeland of human beings, from which human beings originated and developed.

The forest is the "lungs of the earth", and every tree is an oxygen generator and carbon dioxide absorber. Forests can conserve water, increase atmospheric humidity and rainfall, improve the climate, reduce air temperature, and play an important role in the natural cycle of water. Forests can prevent wind and sand fixation, prevent soil erosion, and attack land desertification; Forests, on the other hand, do not provide wood for human beings to improve the environment and regulate the climate. Option D fits the topic. So chosen:

d。Afforestation has become an important part of environmental protection. Afforestation is necessary for windbreak and sand fixation, afforestation is necessary for soil and water conservation, and afforestation is necessary for environmental improvement. In order to encourage the whole people to plant trees, the state also sets March 12 as Arbor Day every year.

All of this is indicative of an increased awareness of the rough huddle environment. However, everything must be done according to the rules, and afforestation is no exception. Awareness of the environmental impact of afforestation, <>

There are still many misunderstandings. It is generally accepted that afforestation is conducive to improving the environment, increasing precipitation and changing the climate. In fact, this kind of understanding is not entirely scientific.

Afforestation can help mitigate climate change for the following reasons:

The impact of afforestation on global warming: forests have a good water storage effect, forests have a good effect of acacia dust to slow down global warming, and have the functions of blocking sandstorms, maintaining water and soil, and changing low air flow.

We can think of forests as a small reservoir that plays an important role in the natural water cycle. Trees can effectively regulate the climate. The reason why trees are able to regulate the climate is that when sunlight shines, the canopy loses some of its photoband source, which lowers the surface temperature and reduces water loss.

Creating habitats for living things is the home of animal life.

Due to global warming, severe soil erosion, land desertification, and human over-deforestation have all destroyed the living environment of animals, which will also bring many species to the brink of extinction, thus making global warming even more serious. Therefore, afforestation can provide a new home for animals and slow down global warming.

Afforestation is a productive activity that creates or renews forests. It is a fundamental part of forest cultivation. Planting trees is beneficial for future generations, "ancestors left shade trees so that future generations can enjoy the cool air."

If the planting area is large, it can form a forest and forest environment in the future, which is called afforestation.

If the area is too small to form a forest and forest environment in the future, it is called tree planting. The basic measures for afforestation are: suitable land and suitable trees, careful land preparation, good seeds and seedlings, appropriate dense planting, tending and protection, tool modification and possible irrigation and fertilization.

Afforestation can provide many useful things to humans. Many fruits and medicinal herbs are forest products; Tea, rubber, and new carbon are all contributions from trees. The use of the forest is really great.

Afforestation has played a role in changing the global climate and has also reduced emissions indirectly. The cost of afforestation is relatively low, so we must pay attention to afforestation.
