How to control the Yellow River? What are the measures for the management of the Yellow River?

To harness the Yellow River, it is first necessary to maintain a comprehensive management of water and soil on the Loess Plateau in the middle reaches of the Yellow River, plant more trees, and reduce the amount of sediment flowing into the river. Next, the lower reaches of the Yellow River were to excavate the riverbed and reduce the height of the riverbed.

The bends of the Yellow River pass through the dusty land in the north, note that it is not sandy land, the flow rate is slow, and the soil is deposited ......The solution, connecting Lanzhou to Sanmenxia section, choosing sand and sand layers to open up the river, fine sand sinking into the river, will prevent soil erosion, and the water quality will be clear. It can be used as a scouring channel. The northern zigzag channel is dredging once every 5 years, and after dredging, the sand and sandy water can be properly introduced, and the river channel should be V type instead of U type, and the sand and sand sediment bottom side can protect the soil and clear water.

Sand and sand should be retained by V-shaped river channels, not U-shaped.

Several platforms can be opened on both sides of the V-shaped shape as stagnant sand and sand.

Sand and dirt should be clearly distinguished.

Lu's method of governing the river.

Sand control leads to the turbidity of the Yellow River, and the sand and sand in the upper reaches of the river should be laid in the river channel with the flow of water to form a sediment layer to protect the soil from collapse, and the sand in the upstream is fixed, and the water flow washes away the soil layer, resulting in the current situation, which is not well treated at all, and it is useless to change the route.

Now that the engineering technology is very developed, the water conservancy department in the north should no longer do the treatment activities of mending the seams.

The middle and upper reaches of the Yellow River are mainly mountainous, and the middle and lower reaches are dominated by plains and hills. Because the middle section of the river flows through the Loess Plateau region of China, it carries a large amount of sediment, so it is also known as the river with the most sediment content in the world. But in Chinese history, the diversion of the lower reaches of the Yellow River has had a huge impact on human civilization.

A variety of trees, do not cut down trees, and protect the ecological balance.

Communicate and discharge sand according to local conditions.

1. Afforestation and returning farmland to forests.

2. Reduce sewage discharge.

Doing it with your heart is more real than anything else.

There are four main measures to control the Yellow River:

1. Persist in afforestation, and do not allow sediment to flow into the Yellow River as it pleases, thus playing a role in fixing sediment.

2. The Loess Plateau should adhere to the management direction of animal husbandry and forestry, increase the vegetation coverage rate in the plateau area, and strictly prohibit land reclamation.

3. Protect forest resources, plant a variety of trees, prevent soil erosion, and reduce natural disasters such as sandstorms, mudslides, and landslides.

Fourth, it is necessary to rationally plan land, build a large number of water conservancy projects, and make rational use of the water resources of the Yellow River.

1. Planting forests and grasses, greening the earth, improving the local climate, planting forests and grasses, expanding vegetation coverage, developing ecological economy, combining resource development with soil and water conservation, conserving water sources, maintaining soil and water, preventing soil erosion, improving local climate, reducing flood hazards, increasing soil fertility, and increasing underground runoff.

2. To control the number of population and improve the quality of the population, the Yellow River Basin should pay attention to the effective control of population growth, and at the same time urge citizens to consciously protect the environment and water resources, use water rationally, and save water.

3. Unified planning, coordinated development of the Yellow River's water resources, unified management, overall preparation of the Yellow River's water resources utilization and dispatch plan, taking into account local conditions, giving full play to the role of large-scale water conservancy projects as hubs, and impounding floods to regulate runoff.

Yellow River hazards. 1. Due to soil erosion in the middle reaches of the Yellow River, the Yellow River carried a large amount of sediment from the Loess Plateau and rushed out of Sanmenxia. The downstream flows through the North China Plain, the lower thane is gentle, the riverbed is wide and flat, the water flow is slow, the kinetic energy of the river is not enough to transport a large amount of sediment carried, and the riverbed continues to silt up and become a world-famous above-ground river.

2. Due to the continuous siltation of the riverbed in the lower reaches of the Yellow River, there is no tributary inflow of the Yellow River in this section, nor can it be recharged by the water source of the underground aquifers on both banks, but the underground aquifer must be replenished by river water infiltration, and the more drought it is, the more serious the infiltration.

As far as I know, since the liberation, great importance has been attached to the management of the Yellow River.

The biggest problem of the Yellow River is that when it encounters floods, there is a danger of bursting the embankment, and in some places the water of the Yellow River is higher than the two banks, becoming a heavenly river, so once the embankment bursts, the disaster involves the lives and property of hundreds of thousands or even tens of millions of people.

After the liberation, the shortage of royal potatoes was harvested and the method of raising the embankment was taken several times, which effectively prevented the embankment from bursting. But if it is higher in this way, the Tianhe River will be higher, like an egg, and the higher it is, the more dangerous it is, so this is not the fundamental method of governance.

Secondly, the problem of the Yellow River is pollution, and the pollution of the Yellow River is becoming more and more serious, especially in the downstream Shandong area.

Again, there is the problem of the Yellow River being cut off.

In my opinion, this is a systemic issue. The fundamental approach to governance is to start from the system:

First, in the long run, we should focus on controlling soil erosion, protect and increase the forest area in the middle and upper reaches of the Yellow River, where soil erosion is serious, increase the vegetation coverage rate, strictly prohibit land reclamation, advocate livestock captivity, reduce soil erosion, increase soil moisture, and improve the ecological environment. Create a sustainable environment.

of the ecological environment. Secondly, it is necessary to continuously dredge the river, rationally use the water from the water allocation and dismantling of the reservoir dam to scour the riverbed, reduce sediment deposition, and deepen the river.

Second, we should make overall plans, make unified plans, use water rationally and scientifically, and avoid wasting water resources such as flood irrigation. In the past two years, it seems that the grasp has achieved some results, and the interruption time has been shortened or even continued.

Third, economic development should be considered from the overall situation, and economic benefits should be taken into account.

It is also necessary to consider social benefits.

and eco-efficiency.

That is to say, while developing the economy, it is necessary to try to avoid the pollution of the environment by waste gas, waste water and waste residue, and maintain the natural environment.

not to be destroyed and to improve the people's living standards. \x0d
