In the endless Inner Mongolia prairie, why are there almost no trees to be seen?

You can often see in some**and** that the Inner Mongolia prairie looks endless, full of cattle, sheep and grass, but there are no trees, some netizens are very strange, thinking that why there are no trees growing in such a big place, in fact, there is a reason. <>

In the savannah, the thickness of the soil is relatively thin, usually only about 20 cm deep, and even in some bushes, the soil thickness does not exceed 50 cm. Further down, it is some hard rock layers, the water content in the soil layer is relatively small, and the annual precipitation in the grassland area is generally relatively small, and the climate change in the grassland is impossible to judge, the water generally evaporates faster, so some of the water in the layer is particularly easy to evaporate, and the tree growth needs a deeper soil layer, so that the roots of the tree can absorb the water and nutrients in the soil. Therefore, the grassland is not very suitable for the growth of trees.

Due to the low amount of precipitation, it is generally difficult for other plants to survive on the grassland, except for some herbaceous plants, so it is not that trees are not planted on the grassland, but that trees cannot survive on the grassland at all. <>

The growth environment of trees needs to have more sufficient sunlight and some appropriate fertilizers, but also have sufficient water, and the environment should be moist, so from the perspective of these living conditions, the grassland does not have these, in some areas of the south, forest resources are very rich, because the south meets these growth conditions, so the big trees can grow particularly well in these areas of the south. Now in some arid areas of the northwest, in the car of Dali to plant trees, this is to improve the local environment, because the climate in the northwest is very dry, desertification, now is more and more serious, if not take some measures, then it may endanger people's survival. <>

Trees need some sufficient conditions to survive better, and the grassland does not have these conditions, so it cannot grow on the grassland, but the grassland also has the advantage of the grassland, can have a larger area to Siyang, and some cattle and sheep can bring better income.

Due to the low amount of precipitation, it is generally difficult for other plants to survive in the grassland, except for some herbaceous plants.

Because the soil in the grassland is not suitable for many trees to grow, its soil and water are only suitable for nourishing some grasses.

This is mainly due to the fact that there is less precipitation in Inner Mongolia, there are more sunny days, and the soil content on the land is relatively low, which is not conducive to the growth of trees.

There are few trees in China's grasslands, but there are trees in the African grasslands, and there are even forests of considerable size. There are few trees in China's grasslands, the first reason is that the soil layer is very shallow, no water storage, and lack of nutrients, so it is difficult for trees to grow tall, and the second reason is that there are a large number of herdsmen in China's grasslands, and cattle and sheep are overwhelming everywhere they go, which can consume a lot of forage in a short time, and cattle and sheep will also eat leaves when they are short of food, and herdsmen also need to consume wood.

The reason why trees cannot grow on the grassland is that the annual precipitation is insufficient, and when it is rainy in summer, there may be saplings that grow on their own, but they cannot survive the long dry season in winter and spring. Only grass can grow, this year-old and withered plant is called thin soil, and there is sand underneath, this is not the reason at all, if the rainfall is sufficient, it will not take hundreds of years for plants to grow luxuriantly, and the accumulation of decaying plants will form a humus layer that is enough for trees to grow, and forests will naturally grow.

There is a problem with the soil in the grassland area: about 50 centimeters below the ground, there is a dense and solid layer of soil, which is called "calcium deposit" because of its high calcium content. The calcium layer seems to be a thick layer of white ash applied underground, and it is difficult for not only trees, but even many shrubs to penetrate the root system, which makes it even more difficult for trees to gain a foothold in the grassland area.

Many herbaceous plants have roots within 50 centimeters, so they are not affected by calcium accumulation and can thrive in grasslands.

From the Qinghai-Tibet Plateau, with the rise of altitude, the grass on the ground is gradually scarce, and slowly the grass is gone, only some bryophytes, and finally the moss does not grow, completely covered by ice and snow. In the southern foothills of the Himalayas, this feature is even more pronounced. At low altitudes, rainfall is abundant and the temperature is suitable, which is conducive to plant growth, and all kinds of plants are generally more luxuriant.

In the case of soil, rainfall conditions are constant, climate should be the main reason.

The rainfall on the Inner Mongolia Plateau is about 100 mm, which is far from enough for the growth of trees. It will be said that the northern edge of the grassland is the primeval forest, and the soil thickness of the place where the primeval forest grows is very different from that of the grassland area.

Even if you occasionally come across a forest on the grassland, it must be a place with thick soil and plenty of water.

Can't grasslands be turned into forests? In fact, it is related to the topography, rainfall, temperature and human factors of grasslands and forests. Forests and grasslands are very common natural landscapes, but their differences are often obvious, there are few big trees in the vast grasslands, but below is the vast jungle meadows, and the grasslands are not much in the forest, after all, there are many big trees blocking the sun, and the grass is not good for growth, so why does the grass on the grassland not only grow trees?

<> savannah, there are very few trees, what's going on? There will be some scarce trees in many places on the grassland, the first thing to say is that not all of them have no trees, for example, there is a natural landscape called the savannah in Africa, and the rare trees are all grass and trees on the grassland, even in our country, the area at the junction of the forest and the grassland is also a natural landscape; But farther away from the forest, there are fewer trees in the grassland. In some places, not a single tree can be seen for dozens of miles around.

What's going on?

South America and the north and south regions north of the equator, which belong to the tropics here, are also the Amazon plains, mainly so it has some of the densest tropical rainforests in the world, but south of the Amazon is the Brazilian plateau, which is higher in South America, and most of it is grassland. Relative to forests and grasslands, which are usually found at high altitudes, the higher the plateau, the fewer trees and more grassy plants, there are almost some world-famous plateau grasslands, but there are few forests, the most typical place is South America.

The grassland climate is drier than the forest, and some also present a seasonal rainy season and dry season, this climate is suitable for the growth of grass plants, but not for the growth of trees, because the roots of trees are very deep, the water is very deep, and it can be drawn, but if the rainfall is low, only shallow soil under the wetland. It is only suitable for the growth of grassy plants with deep roots and lush leaves, grasses grow quickly, and they will grow quickly if there is good rainfall, and when the climate becomes dry, they have basically set seeds and withered, but trees need long-term water supply and need to draw water from deep in the soil, and a very dry environment is obviously not suitable for tree growth.

It is caused by the geological structure, because the soil on the grassland is generally relatively thin, about 20 centimeters, and the soil is hard stone, and the rainfall is relatively sufficient, but the water content in the soil is not particularly high, and the water evaporation rate is very fast, so it is not conducive to the growth of trees.

It is because the temperature above the prairie is relatively high, so the water loss is particularly serious, and the relatively thin soil layer on the prairie is about 20 cm to 30 cm, and the soil layer is generally relatively hard stone.

Because the soil on the grassland is relatively dry, although grass can grow, it is not suitable for planting trees, the fertility of the soil is insufficient, and the climate is not suitable for planting trees.

<> "Why Trees Are Rarely Seen on the Prairie."

In the grasslands, except for the bushes, it is rare to see other trees, especially tall trees, why is that?

The shallow soil layer on the grassland is very thin, generally only about 20 centimeters, and further down there is a hard rock layer. In such shallow soil, tall trees are difficult to grow.

In addition, due to the thin soil layer, it cannot absorb much water, and the strong wind on the grassland makes the water evaporate very quickly, so the water in the soil is quickly lost or lost. Trees need a lot of water to grow, and it is difficult for trees to grow in soils that lack water.

This is also the reason why trees are rarely seen in the grasslands.

Summary. Hello, dear, the characteristics of the hills and trees on the Inner Mongolia prairie: as a mountain, it must have an altitude of more than 500m, a relative undulation of more than 200m, and a steep slope.

The hill, at first, is very small. 1. Lush foliage: Most trees have lush foliage, which can be used for shade and can also be used for birds and squirrels to grow.

2. Environment: Trees can absorb carbon dioxide in the air and store a large amount of carbon in the tissues to improve the external environment. 3. Economic value:

The fruit of the trees is edible, the branches are edible for buildings, and the leaves can be used to make fertilizer.

The temperature range in most areas is generally 65 -85, and the annual temperature range is 13 -16, which is the largest temperature range in China. The Inner Mongolia prairie has a large temperature difference between day and night, high altitude and cold climate, which minimizes the epidemic of infectious diseases in livestock. Pure pastoral areas generally envy the cold weather more, into October some pastoral areas have begun to snow, some places are very serious drought, Chifeng City's Ao Han Banner, is the arid climate.

First of all, China's grassland resources are obviously richer than those of other countries, and in addition to the four major grasslands, the grasslands in the northwest region are full of good growth. Most of the prairies in our eyes are boundless, and the green grass and the blue sky and white clouds reflect each other, which is particularly beautiful. In fact, in the eyes of most people, the growth of trees on the prairie will destroy the sense of beauty, and make people lose the feeling of being extremely comfortable when they see the grassland.

Getting back to the point, on the question of why trees don't grow on the prairie, I helped you sort it out and came up with the following reasons: First, there are a large number of animals in captivity on the prairie, such as horses, cattle and sheep. These animals are grass-eaters, but they also eat trees.

Some prairies can actually grow plants other than grass, but the livestock raised on the prairie are comparable to harvesters, and some newly sprouted plants and small saplings are often swept into their mouths and eaten by them as soon as they emerge; Second, the conditions on the grassland are not suitable for the growth of trees, and generally the grassland cannot grow trees because of the shallow soil depth of the grassland.

As we all know, for a tree to thrive, its root system must be well developed. The soil of the grassland is obviously not suitable for the growth of trees. In addition, the savannah climate is arid and the amount of precipitation is low, and even if the rainfall is abundant, the water only flows through the surface and does not penetrate deep into the soil, so it cannot be stored in the soil for plants to absorb.

In addition, climate, precipitation, light conditions, etc. are also factors that limit the growth of grassland trees; Third, there is a lot of human interference, although the nomads on the steppe mostly live in yurts, once they find trees in good condition, some of them will cut these trees to make wooden houses or other wooden tools.

All in all, it is not important whether the prairie grows or not, except for the grass plants, the important thing is that we have to make reasonable use of the grassland resources and do our best to protect it, after all, the grassland brings us not only visual enjoyment, but also spiritual and spiritual enjoyment.

The shallow soil on the steppe is very thin, usually only about 20 cm, and then descends into hard rock layers. In such a shallow soil layer, tall bai trees are difficult to grow. In addition, because the soil layer is very thin and cannot absorb a large amount of water, coupled with the wind on the grassland, the water evaporates very quickly, so the soil moisture is lost quickly.

And trees need a lot of water to grow, and if there is a lack of water in the soil, it will be difficult for trees to grow.

After a long period of scientific research, it has been found that the soil layer of the meadow is very thin, usually only about 20 cm, and even under dense bushes, the thickness of the soil layer does not exceed 50 cm, and then below it is a layer of hard rock. The fibrous roots of herbaceous plants are flanked. The taproot of the shrub is straight down, but since the plant itself is not tall and the roots are not long, it can thrive on the grass.

On the other hand, trees tend to be taller, taproot, deep-rooted trees and cannot live in shallow soils. Even if some trees grow, a strong wind blows due to the shallow root depth. We know that the growth of trees requires not only a certain depth in the soil layer to allow the roots to absorb the water and nutrients rich in the soil, but also to have enough water.

Due to the shallow soil layer of grassland, even if there is sufficient rainfall, the soil moisture content is still not much, and the grassland water evaporates quickly, so that soil moisture is easy to lose.

Because the grassland does not have the two basic conditions for tree growth, it is not easy for the trees on the grassland to survive. There are very few tall trees in the grassland. Because it is located at a higher altitude, UV radiation is stronger.

Ultraviolet rays can inhibit the growth of plants in higher directions, resulting in plant dwarfing. Usually there is only 20 cm of soil in the grassland, and due to the shallow soil, even if there is enough rainfall, the soil moisture content is still not much. The grassland area has less annual rainfall, coupled with climate variability and rapid evaporation of water, so soil moisture is more likely to be lost, and the growth of trees requires both a certain depth of soil layer and sufficient water, but the grassland does not have these two conditions Conditions are not suitable for tree growth.
