What are the benefits of planting a large number of trees for cities?

1.Trees regulate the climate and maintain ecological balance. Trees through photosynthesis.

Inhale carbon dioxide.

Spit out oxygen to make the air clean and fresh. One acre of forest releases enough oxygen for 65 people to breathe.

2.Trees can prevent wind and fix sand, conserve water and soil, and can also absorb all kinds of dust, one acre of forest can absorb 20-60 tons of dust a year.

3.Forests reduce noise pollution.

A 40-metre-wide forest strip can reduce noise by 10-15 decibels.

4.Tree secretions kill bacteria. There are 3,40,000 bacteria per cubic meter of air in the open space and only 3,400 in the woods.

Windproof, dust reduction purifies the air

1. Tree planting can remove 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 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.

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

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 alleviate the greenhouse effect.

4. Tree planting 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.

The benefits of the tree are as follows:1Trees regulate the climate and maintain ecological balance.

Through photosynthesis, trees inhale carbon dioxide and exhale oxygen, making the air clean and fresh, and the oxygen released by one acre of forest is enough for 65 people to breathe; 2.Trees can prevent wind and fix sand, conserve water and soil, and can also absorb all kinds of dust, one acre of forest can absorb 20 to 60 tons of dust a year; 3.Trees can reduce noise pollution, and a 40-metre-wide forest belt can reduce noise by 10 to 15 decibels. 4.

Tree secretions kill bacteria, with 3 to 40,000 bacteria per cubic meter of air in an open space and only 3 to 400 in a forest; 5.Trees play an important role in maintaining ecological balance, and have functions such as purifying the air, conserving water, maintaining water and soil, and regulating the climate.

Tree planting has the following benefits:

1.Improving the environment: Trees can absorb harmful gases such as carbon dioxide and nitrogen oxides and release oxygen, which can help improve air quality.

2.Maintain water: The root system of trees can be used to stabilize the soil, prevent soil erosion, and maintain water sources.

3.Purify water: Trees can filter impurities and dirt from rainwater to purify water.

4.Regulate climate: Trees can regulate temperature and humidity, mitigating the urban heat island effect.

5.Increase biodiversity: Tree planting can provide food and habitat for wildlife, and increase the number of habitats.

6.Landscaping: Gardens, parks, woodlands, etc. can beautify the environment by planting trees and improve the quality of life of urban residents.

7.Economic value: Timber, fruits, etc. are one of the important economic resources of people, and planting trees helps to promote economic development.

In conclusion, planting trees is not only good for the environment, but also has a positive impact on human society.

The benefits of tree planting include soil and water conservation, resistance to wind and sand, economic construction, air pollution removal, natural dust collectors, etc.

1. Maintain soil and water.

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. Soil erosion is curbed by planting trees, which have large, cracked root systems like crowns that grip the soil like giant hands.

The water of the soil that is caught is constantly absorbed and stored by the tree roots.

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 in 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 then plant them with wild grasses, the amount of sand and gravel that can be blown up 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.

4. Remove air 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 acre of pine and cypress can secrete 2 kg of fungicide for two days and nights.

5. Natural dust collector.

There are many fine hairs and mucus growing on the leaves, which can absorb harmful particles such as carbon and sulfide in the soot, 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".
