Tell us how you see the changes in the Yellow River in recent years?

The Yellow River has always been the mother river of our Chinese nation, and the Yellow River has changed greatly in recent years, first of all, the pollution problem of the Yellow River is very serious, and we should protect the Yellow River

Aren't they all saying that the Yellow River is now clear?

In recent years, the state has vigorously planted trees on the Loess Plateau, and the water of the Yellow River has been further improved.

It is said that the Yellow River is clear and the saints come out. In the past ten years, how come the saints have not appeared.

The water flows everywhere.

Let's let the Yellow River return to natural selection.

In recent years, the biggest change in the Yellow River is that many people have destroyed the environment, throwing garbage in the Yellow River, and now the river water has become very dirty and polluted.

The water pollution situation of the Yellow River is not optimistic, and the Yellow River, as the mother river of the Chinese nation, is responsible for the urban water supply of the eight provinces and autonomous regions along the river.

I think the Yellow River may be a little better now than before, and it won't be as drastic as the land loss was before.

I feel that in recent years, the Yellow River has become worse and worse, and it has become more and more turbid, just like there is a saying that you can't wash it if you jump into the Yellow River, but now it really can't be washed away.

In recent years, the sediment content of the Yellow River has gradually increased, the amount of water is also decreasing, and the man-made damage is becoming more and more serious.

The changes of the Yellow River are getting bigger and bigger, but the Yellow River is still the original appearance of the majestic, the mountains and rivers of Zhuangzhi, the motherland can be felt at the foot of the Yellow River, and everyone still has to protect the Yellow River.

I think the Yellow River has become more and more polluted in recent years, which has something to do with the environment and the air, because now there is more and more pollution.

With the passage of time and the development of the world, the Yellow River is not as good as it used to be, but now the Yellow River is under control and will not continue to deteriorate.

In this Chinese class, we took a text related to "China's 'Cradle'".

Did you know that the Yellow River, the "cradle" of China, was blessed with a warm climate, dense forests and fertile soil thousands to tens of thousands of years ago, so our ancestors chose to live and reproduce here? Therefore, the Yellow River has become the birthplace of the Chinese nation. Now, the Yellow River has changed, and it has become fierce and violent.

Looking back at its "performance" over the past 2,000 years, it is truly astonishing: more than 1,500 breaches and 26 diversions. The Yellow River is no longer the "cradle", it has become a worry for the people on both sides of the river.

Every time the tide rises, it loses its temper, and I don't know how many farmlands and happy families it destroys. Reading this, I was dumbfounded by this staggering number, and question marks swirled in my head: What is it that makes it ferocious?

Why has it become a problem for the Chinese nation?

It turned out that since the Qin Dynasty, the temperature on the Loess Plateau has turned cold, heavy rains have been concentrated, and the structure of the loess itself is loose, so it has caused soil erosion. Second, people graze and cut down uncontrollably, destroying forest vegetation and making the Yellow River a roaring "beast".

When I read about the plan on how to make the Yellow River better, I thought: although we primary school students can't build water conservancy, we can plant more trees and write proposals to contribute to the construction of the "cradle".

After class, I reluctantly closed the textbook, this article inspired me so much!

According to scientists, there are two reasons for the change in the Yellow River. First, since the Qin Dynasty, the temperature on the Loess Plateau has turned cold, and heavy rain has been concentrated. In addition, the loess itself has a loose structure and is susceptible to erosion and collapse, which contributes to soil erosion and allows a large amount of sediment to enter the Yellow River.

Second, the rapid growth of the population and the unrestricted reclamation and grazing have destroyed the forests, destroyed the grasslands, seriously damaged the green vegetation, and lost the natural protective layer of the Loess Plateau, causing serious soil erosion. Every year, 4,000 tons of valuable soil are eroded per square kilometer in the Yellow River Basin, which is equivalent to destroying 5.5 million mu of arable land in a year! To make matters worse, soil erosion has significantly reduced soil fertility and resulted in a significant reduction in crop yields.

The more production is reduced, the more people have to reclaim more wasteland; The more land reclamation, the worse soil erosion becomes. In this way, the more reclamation becomes, the poorer and poorer the reclamation, the more sediment in the Yellow River will be, and the number of breaches and diversions of the Yellow River will become more and more frequent.

The key to bringing the Yellow River under control is to keep the sediment under control and not allow it to flow into the Yellow River as it pleases. After the founding of the People's Republic of China, scientists have devised a plan for the control of the Yellow River. They believe that the Loess Plateau should adhere to the management direction of animal husbandry and forestry.

We must protect forest resources so that the lost vegetation can be restored as soon as possible. Let everyone understand that the destruction of forests is suicide; It is necessary to rationally plan and utilize land, and at the same time, it is also necessary to build a large number of water conservancy projects.

Such a combination of measures will definitely prevent soil erosion, and the dream of the Yellow River becoming better will surely become a reality. Reasons for the change of the Yellow River:

Nature's way: The temperature on the Loess Plateau turns cold, and heavy rains are concentrated, resulting in soil erosion and a large amount of sediment entering the Yellow River.

Human destruction: Rapidly growing human beings have cultivated and grazed without restrictions, and green vegetation has been severely damaged, causing soil erosion.

The relationship between the two reasons:

A vicious cycle of soil erosion. Soil erosion reduces soil fertility and crop yields, and the more yields are reduced, the more people reclaim wasteland, and the more wasteland, the more serious soil erosion becomes.

Serious consequences: Soil erosion has eroded 4,000 tons of valuable soil per square kilometer in the Yellow River Basin, and the fertility of the soil has decreased significantly, resulting in a large reduction in crop yields. As a result, the Yellow River breaches and diversions are becoming more and more frequent.
