Why do we plant trees, and why do we plant trees?

Afforestation, returning farmland to forest, and ecological reconstruction are extremely important. Controlling desertified cultivated land, controlling soil erosion, preventing wind and fixing sand, and increasing soil water storage capacity can greatly improve the ecological environment and reduce the loss of flood disasters.

and employment opportunities to promote the sustainable development of the local economy. The huge forest carbon sink will play a positive role in protecting the global climate system and ecological environment.

There are many more benefits to afforestation.

Automatic thermostat.

In the shade of the trees, the temperature is about 10 degrees lower than in the open field in the summer, and 2-3 degrees higher in the winter.

Natural dust collectors.

There are many fine hairs and mucus on the leaves, which can absorb harmful particles such as carbon and sulfide in the soot, as well as harmful substances such as germs and viruses, and can also greatly reduce and reduce the dust in the air, and one hectare of lawn can absorb more than 30 tons of soot per year. Therefore, people refer to green plants as "natural dust collectors".

Oxygen manufacturing plants.

Leaves absorb carbon dioxide in sunlight and produce the oxygen needed by the body. It has been determined that one hectare of broad-leaved forest absorbs about one tonne of carbon dioxide and releases 700 kg of oxygen per day. For this reason, people refer to greenery as "oxygen plants".

Sterilization station for bacteria.

Pine, camphor, elm and other trees can secrete fungicide to kill tuberculosis bacillus, diphtheria bacillus and other bacteria.

Natural silencer.

Greenery also absorbs sound waves and reduces noise.

Prevent mudslides, prevent flooding of farmland, absorb carbon dioxide...

There are many benefits to afforestation. First, trees absorb carbon dioxide, which helps reduce the greenhouse effect. Secondly, trees can absorb harmful substances in the air and help purify the air.

In addition, trees provide shelter and food for animals. Trees also provide shade and help regulate ground temperatures, helping to reduce sun loss and surface reflections. Trees also provide a place for people to rest, helping to relax and unwind.

Afforestation can also help control soil erosion and protect soil fertility. In conclusion, afforestation helps to protect the environment and improve people's quality of life.

Afforestation can not only green and beautify homes, but also play a role in expanding mountain forest resources, preventing soil erosion, protecting farmland, regulating climate, and promoting economic development.

It is a grand project that is beneficial to the present generation and benefits future generations. In order to protect forestry resources, beautify the environment and maintain ecological balance, many countries in the world have set up Arbor Day according to their actual conditions. With the continuous enhancement of people's awareness of environmental protection and active participation in afforestation activities, the environment in which we live will be continuously improved.

Afforestation is a productive activity of new or renewed forests, and it is a basic part of forest cultivation. Afforestation is called afforestation if the planting area is large and can form a forest and forest environment in the future.

Benefits::

1. Maintain soil and water.

2. Wind prevention and sand fixation.

3. The state bureau reduced noise.

4. Remove pollution.

5. Beautify the environment.

6. Maintain ecological balance.

7. Manufacture of oxygen.

8. Adjust the temperature.

9. Eliminate bacteria.

10. Generate economic benefits.

Tree planting: China has a tradition of planting trees since ancient times, and many interesting stories advocating afforestation have emerged. The best time to plant trees is the Qingming season, when the climate is warm and the spring rain is sprinkled, which is conducive to the survival of saplings.

Afforestation is of great significance for regulating climate, conserving water and reducing air pollution. March 12 is the official Arbor Day in China.

1.Planting trees removes complete pollution.

According to statistics, one acre of forest can absorb 26,000 kilograms of dust a year, absorb 67 kilograms of carbon dioxide per day, and release 48 kilograms of oxygen; It can absorb 4 kg of toxic gas sulfur dioxide in a month, and one mu of pine and cypress can secrete 2 kg of fungicide for two days and nights, which can kill tuberculosis, typhoid fever, diphtheria, dysentery and other bacteria.

2.Planting trees can reduce noise and beautify the environment.

It can reduce noise, beautify the environment, maintain ecological balance, and provide an ideal place for human beings to study, work, play and live.

3.Planting trees balances the earth's carbon dioxide.

Forests are the main consumers of carbon dioxide, and every 10 tonnes of dry matter produced per hectare of forest absorbs 16 tonnes of CO2 and releases 12 tonnes of oxygen, making forests a huge reservoir of oxygen. Therefore, afforestation has become the main way to mitigate the greenhouse effect.

4.Planting trees can prevent wind and fix sand.

Forests can reduce the intensity of wind erosion by reducing wind speed and changing wind direction; The strong root system of forest trees, especially shrub trees, can hold soil particles in place. Practice has proved that by creating windbreak sand forests and cooperating with agricultural and water conservancy measures, good windbreak and sand fixation effects can be achieved.

1 Afforestation can purify the air, beautify the environment, green the motherland, etc., and it can also produce oxygen for people to absorb and inhale carbon dioxide exhaled by people. If we do not plant a lot of trees, it will be difficult for the oxygen on the earth to meet the needs of humans and various organisms.

2 Afforestation also reduces noise. Noise pollution has caused great harm to human life, study, work, rest, etc., and can be said to be people's "enemy". Therefore, we should pay more attention to afforestation.

Noise can also make human beings hear weakened, deaf, stupid, and abnormal heart, blood pressure, and nerves in the long-term life and thought infiltration. It can even make people die under the torment of long-term noise. In this way, the afforestation will reduce the noise.

4.5 times 3 Afforestation not only has very important environmental benefits for human survival, but also has huge economic benefits for human production and life. The rational exploitation and utilization of natural resources by human beings is the main cause of ecological imbalance. Indiscriminate deforestation, deforestation, overgrazing, etc., will destroy forests and pastures, cause soil erosion and land desertification, and make sandstorms more frequent.

Unreasonable development and occupation of land have led to a decrease in the area of cultivated land. <

4. Afforestation plays an important role in maintaining ecological balance, and has the functions of producing oxygen, purifying the air, conserving water sources, maintaining water and soil, regulating climate, preventing wind and sand fixation, and eliminating noise. Now that we understand so many benefits of afforestation, we must consciously fulfill the obligation of afforestation and lay the foundation for creating a beautiful home.

First, cutting down trees is easy to soil erosion, if the vegetation coverage rate is low, the rainy season will cause a large amount of soil erosion, destroy the fields, fill the riverbed, and silt up the mouth of the sea, which is extremely harmful.

One hectare of forest land can store at least 3,000 cubic meters more water than bare land. The water storage capacity of 10,000 acres of forest is equivalent to a reservoir with a storage capacity of 1 million cubic meters, and the construction of such a reservoir requires an investment of more than 10 million yuan.

2. Afforestation can prevent wind and fix sand. Cutting down trees is easy to cause wind and sand to rage, and without the protection of vegetation in desert areas, the desert will soon become a desert, which greatly increases the difficulty of governance. Shelterbelts have the effect of slowing down wind speed, and their effective range is within 40 times of tree height, of which the best effect is in the range of 10 20 times, which can reduce wind speed by 50%.

In the farmland forest network, the wind speed can usually be slowed down by 30% to 40%, and the relative humidity can be increased.

5% to 15%, increase soil moisture content by 10% to 20%. It has been determined that the canopy can intercept about 20% of precipitation, which greatly weakens the impact of raindrops. As long as there are 1 cm thick litter on the surface, the surface runoff can be reduced to less than 1 4 of the bare land, and the sediment loss can be reduced to less than 7% of the bare land.

3. Afforestation can remove complete pollution. The consequences of cutting down trees can be imagined, and the quality of our living environment will be seriously reduced! Air pollution, dryness, bacteria ......According to statistics, one acre of forest can absorb 26,000 kilograms of dust a year and 67 kilograms of carbon dioxide per day.

48 kg of oxygen was released; It can absorb the toxic gas sulfur dioxide in a month.

4 kg, one acre of pine and cypress can secrete 2 kg of fungicide for two days and nights, which can kill tuberculosis.

Typhoid, diphtheria, dysentery and other germs. In cities, a single tree can store the pollutants emitted by a car traveling 16 kilometers a year. Many trees can absorb harmful gases, such as 1 hectare of cedar forest, which can absorb 60 kg of sulfur dioxide per day, others such as almond and oleander.

Ginkgo biloba, sycamore, etc. have the function of absorbing sulfur dioxide. When the urban green area reaches more than 50%, the pollutants in the atmosphere can be effectively controlled.

Fourth, afforestation can also reduce noise, beautify the environment, the forest can increase the air humidity of the Qi people, an adult tree, a day can evaporate 400 kg of water, so the air humidity in the forest rises significantly. It has been calculated that for every 1% increase in urban green space, the local summer temperature can be reduced by 0.1 degrees Celsius.

Automatic thermostat.

5. It plays an important role in the conservation of biodiversity. If a large number of trees are cut down, the living environment of the species will be destroyed, and the five middle schools will continue to become extinct due to the loss of their homes. Some experts ** say that if the earth loses its forests, about 4.5 million biological species will cease to exist, 90% of the fresh water on land will flow into the sea, and human beings will face serious water shortages.

The loss of forests has increased wind speeds by 60 to 80 percent in many areas, and hundreds of millions of people have lost their lives to ...... wind
