A bowl of water and half a bowl of mud, why is the water of the Yellow River so turbid

China is a vast country of 9.6 million square kilometers.

The land of the numerous mountains and rivers and the places where people live, which also makes Chinese culture.

Colorful. The two largest rivers in China are the Yellow River and the Yangtze River. As we all know, the Yellow River is the mother river of China.

It has not given birth to countless Chinese, so it is also deeply admired by people. The Yellow River is known to be very turbid because the entire middle of the river flows throughLoess Plateau, and mixed with yellow mud, producing 1.6 billion tons of yellow sand every year.

Some people are also confused about this. Why is the Yellow River so muddy that we can still drink it? Moreover, Why is there so much fish in the river?

In fact, the water we drink from the Yellow River is filtered, but the Yellow River is so turbid that how do they live? Next, let's take a look. In fact, many people misunderstand the meaning of turbidity and pollution.

Murky water doesn't mean fish can't survive. So the turbidity of the river water only affects the eyesight of the fish. For their part, they can still live in the water.

If the pollution is severe, it will leave the water without oxygen and food, which will also lead to the death of a large number of fish. Only severe pollution can lead to the extinction of seafood, so it is quite normal for large numbers of fish to survive in the water of the Yellow River. Not only that, but the water of the Yellow River is not as muddy as the river as a whole.

Overall, the water quality in the upper reaches of the Yellow River is quite good. It provides a lot of food and oxygen to the fish.

In the middle and lower reaches of the river, the water surface can be cloudy due to too much sediment. In fact, there is still food and oxygen available to the carp underwater. However, where the concentration of sediment is too high and the current is too fast, there are no fish.

In the water flow is slow and there is seaweed.

place, these things provide good conditions for carp. Therefore, the fish in the Yellow River are fat and delicious.

Many people think it's also strange, can fish really breathe in such murky water? In fact, carp mainly rely on the gills to breathe, so there is no problem of obstruction of breathing. In addition, carp can help in food digestion by inhaling sediment properly.

I wonder if you've ever heard the saying "If the water were clear, there would be no fish". If the water is too clear, there will be no algae.

Therefore, it is not suitable for fish growth, so the growth of fish in turbid water will not be affected. It is the moderate turbidity of the Yellow River that can provide the fish with richer food and better food.

If the water of the Yellow River is too clear, even if there are fish in it, there is no way to meet the living conditions of the fish. Yellow River carp.

The reason why it is fat and beautiful is because the Yellow River provides abundant nutrients. In the lower reaches of the Yellow River, silt forms alluvial plains.

It is also very helpful for farmers to grow crops and improve people's living standards.

Because the Yellow River flows through the loess high-slope areas such as Shanxi in Shaanxi, the water of the Yellow River is very turbid because the loess is relatively soft and easy to be carried away by the current.

This is mainly because the Yellow River flows through the Loess Plateau, and the sediment is washed into the Yellow River.

The reason why the water of the Yellow River is so turbid is that the entire central part of the Yellow River flows through the Loess Plateau, which will carry a large amount of sediment, which is also mixed with yellow mud, and can produce a large amount of yellow sand every year.

The middle reaches of the Yellow River flow through the Loess Plateau, most of which are loess distribution areas, and the vegetation of the Loess Plateau is seriously damaged, the soil is loose and the soil erosion is serious, so to the middle reaches, the amount of sediment in the Yellow River water increases greatly, and some people say that the Yellow River water in the middle reaches is a bowl of water and half a bowl of sand.

Especially after the heavy rains, the Yellow River is almost a rolling mudflow.

Most of the middle reaches of the Yellow River are loess distribution areas, and soil erosion is serious, so in the middle reaches, the amount of sediment in the Yellow River water has increased greatly, and some people say that the Yellow River water in the middle reaches is a bowl of water and half a bowl of sand.

Especially after the heavy rains, the Yellow River is almost a rolling mudflow. (List of Design Talents).

The water of the Yellow River is "a bowl of water and half a bowl of sand.""Reason:

The Yellow River originates in the ancient Zonglie region at the northern foot of the Bayankala Mountains on the Qinghai-Tibet Plateau, and its source flows all the way down from the source of the Yellow River and receives many small streams before flowing into the largest pair of the Yellow River's headwater"Sister Lake"-- Zhaling Lake and Ngoring Lake, after which the main stream was formed and surged eastward. The swampy steppe area was once home to thousands of highland lakes. In recent years, under the influence of global warming, there has been an extremely abnormal drought in the headwaters of the Yellow River, which has led to the accelerated degradation and desertification of the local grasslands, and the drying up of rivers and lakes is very serious The average annual natural runoff of the Yellow River for many years is 58 billion cubic meters, which is equivalent to 1 17 of the Yangtze River, accounting for only 2 of the total river runoff in the country, ranking fourth among the seven major rivers in China.

The per capita water volume in the basin is 593 m3, which is 25 of the national per capita water volume; The average water per mu of cultivated land is 324m3, which is only 17 of the average water per mu of cultivated land in China. Soil erosion in the upper and middle reaches of the Yellow River is very serious, resulting in serious siltation of the lower reaches of the river, and the riverbed is raised by an average of about 10 centimeters per year. The average sediment transport volume of Sanmenxia Station of the Yellow River is about 1.6 billion tons for many years, and the average sediment volume is 35kg m3, ranking first among the major rivers and unique among the rivers in the world.

If 1.6 billion tons of sediment were piled up into an earthen embankment with a height and a width of 1 meter, the length of which would be three times the distance from the Earth to the Moon, and it would be possible to circle the Earth's equator 27 times. The saying that "jumping into the Yellow River can't be washed away" is also derived from the description of the Yellow River's sediment. At the same time, the sediment particles of the Yellow River are very fine, and sometimes the river water is even in a muddy state, which is really difficult to wash off on the body!

60% of the Yellow River's water comes from Lanzhou and the northern foot of the Qinling Mountains, and more than 90% of the sediment mainly comes from the area between Hekou Town and Longmen and the upper reaches of the Jing River, Beiluo River and Wei River. 60% of the annual water volume and 80% of the sediment volume are concentrated in the flood season, which in turn is mainly concentrated in a few heavy rains and floods. The concentration of water and sediment distribution has made it very difficult to develop and utilize the water resources of the Yellow River and to flood control in the lower reaches.

Because the middle section of the Yellow River flows through the Loess Plateau region of China, it carries a large amount of sediment, so it is known as the river with the highest sediment content in the world.

Turbidity, a bowl of Yellow River water is left to settle and the bottom half is sand.

People use a bowl of water and half a bowl of sand to describe the turbidity of the Yellow River.

The main reason why the water of the Yellow River is very turbid is that the water contains a lot of sediment. The sediment of the Yellow River mainly comes from the Loess Plateau, and the soil erosion on the Loess Plateau is serious, resulting in a large amount of sediment in the Yellow River. In order to make the water of the Yellow River clear, it is necessary to do a good job in soil and water conservation on the Loess Plateau, and to conserve the water and soil through such measures as planting trees and grasses and building terraced fields.

Rolling Yellow River.

A bowl of water, half a bowl of mud'' refers to the sediment problem in the lower reaches of the Yellow River.

The upper reaches of the Yellow River pass through the main mountain valleys, the water source is the alpine ice and snow meltwater, so it is relatively clear, the middle reaches pass through the Loess Plateau, the Loess Plateau has loose soil, serious soil erosion, resulting in more sediment in the lower reaches.
