The role of various trees, what are the roles of trees

Roles and benefits of trees.

1. Trees can regulate the climate and maintain ecological balance, and trees inhale carbon dioxide and exhale oxygen through photosynthesis, so that the air is clean and fresh. One acre of forest releases enough oxygen for 65 people to breathe for a lifetime.

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

4. The secretions of trees can kill bacteria. There are thirty or forty thousand bacteria per cubic meter of air in the clearing, and only three or four hundred in the forest.

5. Trees can lower the temperature and increase the humidity. In the hot summer, you can clearly feel that the temperature in the woods is lower than in the surrounding area.

Pine fir conifers, tall trees provide mainly timber.

The camphor tree mainly provides aromatic oils.

Sandalwood trees mainly provide medicine for cardiovascular diseases.

Yew mainly provides medicine for high blood pressure.

Star anise, cinnamon mainly provides condiments.

The pine trees in the south can also be harvested to extract rosin, turpentine, and ink smoke, which are used in paint, papermaking, chewing gum, and laser printer charcoal. There are too many to list. Of course, greening, purifying the air, conserving water and soil, and reducing carbon emissions in the atmosphere are all all common effects.

The role of trees: 1. Photosynthesis, absorbing carbon dioxide and releasing oxygen. 2. It can adjust the air humidity.

3. Fix the soil and prevent soil erosion. 4. It is a kind of barrier to block the wind and sand. 5. Increase greening and beautify the environment.

6. Wood carving and other wood products raw materials. 7. Trees can reduce noise pollution.

Trees regulate the climate, purify the air, prevent wind and noise, and are man's best friend.

Trees are oxygen manufacturing plants. One hectare of broadleaf forest can absorb 1 ton of carbon dioxide and release tons of oxygen in 1 day.

Trees are dust filters. When a dusty air stream passes through a woods, the dust with larger particles in the air drops rapidly as the wind speed decreases. Some trees have fluffy or oily skins that can stick dust to the body, thus greatly reducing the dust content of the air flow passing through the woods.

Trees are good at sterilization. Many trees secrete cidin during their growth to kill various pathogens brought by dust. The amount of bacteria per cubic meter of air is 4 million in department stores, 580,000 on boulevards, 100 in parks, and only 55 in forest areas.

In addition to this, trees are natural reservoirs and natural air conditioners. Therefore, we need to protect the destruction of forests, such as using less disposable chopsticks, water cups, lunch boxes and other products, and more reusable products to reduce the consumption of forest resources.

The functions of trees are: trees can purify the air and provide oxygen; Trees can absorb dust; Trees prevent desertification; Trees remove pollution; Trees conserve soil and water.

1. Trees purify the air and provide oxygen

The natural trees of Dahuliang are photosynthesizing every day, releasing a large amount of oxygen, which is what people need most in their lives. And Qi does leakage and trees can purify the surrounding air, absorb dust, and can also provide us with shade and light.

2. Trees can absorb dust

When a dusty air stream passes through a forest, the dust with larger particles in the air will quickly descend onto the blades as the wind speed decreases. In addition, some trees have fluffy skin, and some can secrete oil, which can stick dust to the leaves, so it also reduces the dust in the air and purifies the air.

3. Trees can prevent desertification

Trees also prevent desertification, as we all know, because sometimes successive heavy rainstorms can wash away a lot of soil from the ground, leading to desertification, and the roots of trees are so strong that they can hold the surrounding soil firmly in place and prevent soil erosion.

4. Trees can remove pollution

According to statistics, one acre of forest can absorb 20,000-60,000 kg of dust a year, absorb 67 kg of carbon dioxide per day, and release 48 kg 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.

5. Trees can maintain water and soil

To curb soil erosion, it is necessary to plant trees because trees have a root system as large as a canopy, which 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.

The functions of trees are: photosynthesis, transpiration, fixing the soil, preventing soil erosion, barrier effect, blocking wind and sand, increasing greening, beautifying the environment, appreciating beauty, industrial value, medicinal value, making medicinal materials, etc. <

1. Photosynthesis, absorbing carbon dioxide and releasing oxygen.

2. Transpiration, regulating air humidity.

3. Fix the soil and prevent soil erosion.

4. Barrier function, wind and sand.

5. Increase greening and beautify the environment.

6. Appreciating the value of beauty and increasing the artistic component.

7. Industrial value, wood, wood carving and other wood products.

8. Medicinal value, made into medicinal materials.

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