What are the main measures to control the Yellow River and what are the measures to control the Yell

First, the control of channel downcutting is the foundation of erosion control.

2. Increasing resistance and decreasing speed is an important measure to stabilize the river potential.

3. The construction of wetlands through rivers and lakes is a chain to improve the ecology of the Yellow River.

Fourth, the control of point source pollution is the key to solving the pollution problem.

Specifically, according to the different characteristics of the upper, middle and lower reaches of the Yellow River, measures should be adapted to local conditions, comprehensive management should be carried out, and thorough management should be carried out. The upstream slope is steep and rapid, mainly to build reservoirs, power generation, and fish farming, make full use of water resources, and vigorously develop forestry and animal husbandry at the same time.

Soil erosion in the middle reaches is particularly serious, and afforestation, grass planting and soil conservation are the mainstay, and vigorous development of forest trees and fruits and animal husbandry. In the middle and upper reaches, a large amount of farmland will be returned to forests and grasslands, and the grain and daily necessities needed, as well as electricity, fish, meat, livestock products, and fruits, will be planned to be cut down and traded downstream. The lower the river barriers, the more serious the threat and the most difficult to manage.

It is necessary to re-excavate two standardized, multi-functional man-made Yellow River, and the two rivers of A and B must be alternated to open water, navigate, and rotate to dredging, and after dredging, they can be planted and cultivated in time without further construction. In the event of a catastrophic flood, the two Yellow Rivers were discharged at the same time to ensure the safety of the downstream. The above-ground river is transformed into an irrigation canal, the low height of the canal is convenient for irrigation, and the irrigation canal can also distribute floodwater.

The Yellow River, which has been thoroughly controlled, will never overflow and benefit all generations, and the benefits are endless.

Soil and water conservation should be strengthened mainly in the midstream. Details: planting forests and grasses in the upper reaches, etc. Terraced fields in the middle reaches, soil and water conservation, etc. the construction of water conservancy hubs downstream.

If it's an exam, I'm 100% right, and if it's a professional, I'm going to answer the front.

The key to "controlling the Yellow River" lies in "controlling desertification", and the fundamental measures are to vigorously carry out soil and water conservation work, control soil erosion, and reduce sediment discharge in the upper and middle reaches, especially in the Loess Plateau. On the other hand, the construction of embankments and dams in the lower reaches of the Yellow River and the strengthening of the embankments of the Yellow River have played a great role in ensuring the safety of people's lives and property on both sides of the lower reaches of the Yellow River

Therefore, the answer is: the key to "controlling the Yellow River" lies in "controlling desertification", and the fundamental measure is to vigorously carry out soil and water conservation work, control soil erosion, and reduce sediment discharge in the upper and middle reaches, especially in the Loess Plateau

The Yellow River is the second largest river in China, one of the world's most famous rivers, and one of the birthplaces of early Chinese civilization. However, due to the harsh natural conditions and the interference of human factors, the Yellow River often suffers from disasters such as floods and breaches, which have a serious impact on the economy and society of the surrounding areas. Therefore, people have also made many efforts and taken a variety of measures in the management of the Yellow River in history

1.Establish a hydrological station system for the Yellow River to monitor river level, flow and water quality information in real time, and provide monitoring, early warning and early warning systems for ensuring the safety of the Yellow River's water resources;

2.Establish water conservancy projects, including the construction of dams, the control of the Yellow River, and the strengthening of dikes to resist flooding and reduce peak flood flows;

3.Strengthen management and dispatch to coordinate the use and development of upstream, midstream and downstream water resources through effective water resources dispatch to reduce disasters and promote economic development in coastal areas;

4.Promote water-saving technologies and encourage irrigation system reform and water-saving actions to avoid significant water waste;

5.Scientific and technological innovation, the application of advanced technologies and methods, research and development of flood control measures, water resources protection and sustainable development technology, ecological restoration and coordinated development, etc., to improve the effectiveness of the Yellow River governance.

The governance of the Yellow River is a long-term process, which requires the efforts of experts, citizens and all walks of life to work together. In the process of governance, it is necessary to comprehensively consider the natural situation, social and economic development and ecological protection and other factors to improve the governance effect of the Yellow River and ensure the safety of people's lives and property. <>

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.
