Why do forests protect from wind? How the forest is windproof

With the continuous development of social economy, in our real life, we will encounter a variety of problems that make us very confused, especially many friends are very curious about why the forest can be windproof, in fact, in our life, why the forest can be windproof is able to solve this problem through scientific theories, the main reason why the forest can be windproof is because the forest area is very large, when the wind and sand blow, The forest is able to directly block the path of these windy sands.

First of all, we have to understand this problem, then we must know why the forest can have such a powerful effect, mainly because the area of the forest is very large, and in windy weather, if there is wind and sand, then the forest can directly block the way of these wind and sand, and these wind and sand can only bypass the forest and then blow forward, but in this case, there is also a part of the wind and sand will enter the forest, but because the forest is relatively dense, and has a lot of leaves, Together, these leaves provide a good barrier to these things.

After the leaves block these things, the wind speed will gradually decrease, and eventually the wind will gradually slow down and gradually disappear, which is why the forest can achieve a good windproof effect, and in our country we must plant trees, we must protect our environment, because only by protecting our environment, can we better protect our city, not be damaged, in order to protect the environment we live in, can be better arranged.

To sum up, we can obviously know why the forest can achieve a good windproof effect, in our real life, we must protect the forest well, only in this way can we make our life better, can make our earth more perfect, which is very important for each of us.

Because of the resistance, and also to avoid the head-on conflict with the wind, the forest is also protecting us, because there are many trees, so it can protect us.

Due to the presence of forests, it can effectively affect the speed and direction of air mass flow, and obviously prevent soil erosion. When the wind encounters the forest, due to the obstruction of the branches of the forest and the shaking of the branches and leaves, the wind speed entering the forest can be quickly reduced, and the wind speed of the windward and windward sides of the forest can also be reduced. In generally flat areas, there is a significant windbreak effect in the leeward area of the forest belt where the tree height is 20 times higher.

For a long time, countries around the world have made great achievements in using forests to reduce wind speed and create wind-proof and sand-proof forest belts and forest nets to protect farmland, pastures, orchards and roads and prevent the damage of wind and sand.

That's because the trees in the forest are relatively lush, and secondly, because there are certain bumps, so they will slowly prevent the wind.

The forest area is very large, and when the wind and sand blow, the forest blocks their way, and the wind and sand can only bypass the forest and blow forward, and part of the wind gets into the forest, and when it hits the branches and leaves, the wind will decrease.

Forests conserve water and are huge reservoirs that play an important role in the natural cycle of water. "The green mountains are always there, and the clear water flows forever", and the tree is always associated with the water.

Some of the rainwater that falls is intercepted by the canopy, and most of it falls to the dead branches and leaves under the trees and the loose and porous woodland soil to be stored, some of which is absorbed by the roots of the plants in the forest, and some of which are returned to the atmosphere through evaporation.

When the wind blows through the forest, the wind speed below the forest will be reduced a lot, which is the forest windproof.

When the wind hits the forest, part of it has to go around the forest before it can move forward, and the other part is like drilling in the woods. In this way, many tree trunks and branches and leaves were blocked, and the branches and leaves swayed loudly, and as a result, not only the wind speed was slowed down, but the force was also greatly reduced.

The tree species in the coastal defense forests in South China are mainly casuarinas and privet; The main tree species for sand control afforestation in the southern coastal area is Kulang tree; In Hainan's coastal defense forest, experts advocate the use of coconut trees, casuarinas and other tree species; Island shelterbelts can choose tree species such as casuarina, coastal hibiscus, oleander, tamarix, Zhongshan fir, Mexican lupus, and tung tree.

Summary. Dear, thank you for your patience, I am glad to answer for you, the main tree species in the windbreak zone should be selected from fast-growing tall deep-rooted trees, such as poplar, acacia, elm, paulownia, sand date, camphor tree, etc. The tree species in the coastal defense forests in South China are mainly casuarinas and privet; The main tree species for sand control afforestation in the southern coastal area is Kulang tree; In Hainan's coastal defense forest, experts advocate the use of coconut trees, casuarinas and other tree species; Island shelterbelts can choose tree species such as casuarina, coastal hibiscus, oleander, tamarix, Zhongshan fir, Mexican lupus, and tung tree.

So shrubs are not very suitable for windbreaks, dear! <>

I hope my answer can help you and have a great day! <>Thank you. You're welcome, dear <>

Glad we could help you<>

What kind of tree is good for the windbreak of fruit trees, here is to plant a large area of fruit trees, generally a relatively small area of orchards, if you make a large windbreak I think it is not cost-effective, here mainly refers to a large area of orchards, if it is a hundred acres of orchards with ten acres of windbreak, then it is necessary to reduce the income of ten acres, that is, ten percent less, if it is a plain area and layers of fortification, then the loss is greater, is to use the fastest growing aspen as a windbreak, the height of twenty meters, then the windbreak can only reach one hundred meters, Moreover, the 20-meter-tall poplar tree is afraid that it will also grow for ten years, so some short-lived fruit trees are afraid that they have already passed half of their life, so my humble opinion is to choose a variety of fruit trees that should be able to be afraid of the wind. Peach, apricot, persimmon, jujube and other short-fruited varieties, the other choice of windproof terrain, such as hills, mountain recesses and other terrain, to form a natural windproof, so that the effect is better, is the most cost-effective design.

<> orchard windbreak for the selection of trees to be used as fruit tree windbreaks, first of all, it is necessary to consider that there is no mutual harm to the planted fruit trees, such as the spread of pests and diseases, and then to consider the economic value of the windbreak. For agricultural production, there is no need to consider the beauty of the windbreak, only the practical value, but if it is an ornamental windbreak, it must be combined with the beautification effect, which is also a problem that Agricultural University has to consider as a greening management staff.

Of course, the woodland that can be protected from wind needs to have a certain height, at least 25 to 30 meters high. Choose some tall fast-growing trees according to the local environment.

Such as poplar trees, paulownia trees.

Acacia trees, willows, etc., are planted at a density greater than the normal dense planting. If you want to set up an impermeable windbreak, you can plant some shrubs suitable for local growth under the trees to assist.

The windbreak should be set up according to the location of the orchard, the local perennial wind direction, the windbreak is located at the upwind outlet, in order to reduce the area occupied by the windbreak, the width of the windbreak is generally not more than 20 meters, but also take into account that the windbreak may affect the growth of fruit trees, the windbreak should be separated from the orchard by 20 30 meters, and dig a ditch with a depth of about one meter between the windbreak and the orchard, which is used to block the windbreak roots and fruit trees from competing for nutrients. If the orchard area is large, or the orchard span is large, consider adding a windbreak forest at an interval of about 300 meters.

The windproof facilities (forests and nets) of oases in arid areas not only have the effect of wind and sand prevention, but also can inhibit soil evaporation and plant transpiration, so as to facilitate the rational use of water and promote crop growth. The growth height and yield of crops changed significantly with the protection distance of the windbreak. In addition, as mentioned above, there is a significant difference in temperature and humidity between the oasis and the desert, which must have a local circulation between them, and the windbreak facility increases the oasis effect by reducing the wind speed and regulating the change of temperature and humidity at the same time.

Of course, it is necessary, the primary role is to prevent the wind and fix the soil, if you choose some ornamental trees, you can also beautify the environment, if you choose some fruit trees, you can also bring a part of the harvest.

The forest can block the wind and sand, and prevent the yellow sand on the ground from flying in the sky; Forests can store water, conserve soil, and store water to prevent flooding in rivers during the flood season; Forests can also regulate temperatures, like air conditioners, warm in winter and cool in summer; More importantly, the forest is also a habitat for all kinds of animals, especially birds, and it is a good environment for animals to live in the forest.

The proposition that forests are windproof is true.

The role of forests is many.

Forest is a biological community with trees as the main body, which is an ecosystem formed by the interdependence and mutual constraints between concentrated trees and other plants, animals, microorganisms and soils, and the interaction with the environment. It has abundant species, complex structure, and a wide variety of functions. Forests are known as the "lungs of the earth".

The trees in the forest photosynthesize, provide oxygen, shelter other plants and animals in the forest, provide food for animals, and protect the soil from wind.

In order to protect oases and cities from high winds and quicksands, windbreaks are often planted on the edge of the desert.

Therefore, we support and encourage the planting of windbreaks.

Question 1: A Question 2: B Analysis

Question 1: As shown in the figure below, the dotted lines represent the wind speed within 6 meters of the ground level for four types of forests with different structures. The wind speed is about 1 km h, the wind speed is about 3 km h, the wind speed is about 3 km h, and the wind speed is about 6 km h.

Therefore, the windproof effect is the best in such areas. Question 2: From the perspective of regional differentiation, North China has a temperate monsoon climate, and the natural vegetation formed is temperate deciduous broad-leaved forest.

According to the natural conditions of the place, it is suitable for creating a broad-leaved dense forest. Item b is in line with the topic.
