Summary. At present, part of the river has been cleared. In 2022, the Yellow River will be 5,464 kilometers long, not all of which will be turbid, but it will be clear in the upper reaches of the Qinghai-Tibet Plateau, and the clear water section will last until 1,901 kilometers.
The Yellow River began to turn yellow from Dahejia Town, Linxia Hui Autonomous Prefecture, Gansu Province, because the Yellow River water carries a large amount of sediment, resulting in this section of the Yellow River water is very turbid, the only way to make the water in the middle and lower reaches of the Yellow River clear is to maintain the water and soil in the upper and middle reaches of the Yellow River, so as of 2022, some areas of the Yellow River water have become clear, but most areas have not become clear.

From January to March, the water quality of the Yellow River Basin showed a significant improvement compared with the same period last year. The Northwest Rivers - Similar cross-section ratio, the overall water quality status is good.
-
1. The Yellow River Basin is located in an arid and semi-arid area, with small river runoff, coupled with the uneven distribution of runoff during the year, the flow is very small during the dry season, and the downstream will even be cut off.
2. The large population and large water consumption in the basin have aggravated the pressure on the water resources of the Yellow River.
3. A large amount of uncontrolled discharge of industrial pollution, especially the discharge of a large amount of substandard wastewater and the illegal discharge and leakage, cause serious pollution in the middle and lower reaches of the Yellow River.

Xinhuanet, Beijing, March 6 (Reporter Gu Ruizhen, Wei Minli) "The deep mining of coal, gravel and dust in the quarrying process, urban wastewater and sewage, and soil erosion are seriously ......All these threaten our mother river, and if it is not comprehensively managed in time, it will inevitably affect the development of the industrial economy and the health of the people in the region along the Yellow River and even the whole country.
Xie Kechang, academician of the Chinese Academy of Engineering and president of Taiyuan University of Technology, and member of the CPPCC National Committee, looked worried when he talked about this issue.
The Yellow River is the mother river of the Chinese nation and the cradle of Chinese civilization. "In the past 20 years, the Yellow River has been affected by industrial development and urbanization, and it has been affected by unprecedented damage. Committee member Xie Kechang told reporters that through more than 700 kilometers of field investigations in more than a dozen counties in four cities along the western section of the Yellow River, it was found that the protection of water resources in the Yellow River is currently facing several major challenges
The deep mining of coal has seriously polluted the water resources of the Yellow River. It has been estimated that mining 1 ton of coal costs 2 to 4 cubic meters of groundwater. The Shanxi basin of the Yellow River produces 1.4 billion tonnes of coal annually and discharges at least 280 million cubic metres of pit water into the Yellow River every year, and the water from these pits contains many complex components, including heavy metals and radioactive ions, which seriously pollute the Yellow River's water sources.
All kinds of tailings with unclear responsibilities pose a threat to the Yellow River's water resources. "Who pollutes, who remediates" is the responsibility of enterprises for their pollution, but once these enterprises go bankrupt or close, it becomes difficult to solve the problem of who bears the follow-up environmental pollution control problems.
The main stream of the Yellow River is densely populated with quarrying sites, and the gravel and dust in the quarrying process directly pollute the Yellow River's water resources. Municipal wastewater and sewage along the banks and tributaries of the Yellow River directly pollute the water resources of the Yellow River.
Soil erosion causes physical pollution of the Yellow River's water resources, and chemical fertilizers and pesticide residues used in agricultural production flow with the water, which further aggravates the water pollution of the Yellow River.
In view of the above situation, Xie Kechang suggested that through the rational planning and integration of coal resources along the Yellow River, the recovery rate should be increased, the total amount of mining should be controlled, and the pit water should be discharged up to the standard. Adhere to the principle of "prevention first", and effectively implement the treatment measures of "whoever pollutes shall be treated"; Delineate reasonable quarrying and ash burning areas as soon as possible, and change the status quo of scattered management of quarrying and ash burning; As soon as possible, unified arrangements will be made for urban sewage treatment in the Yellow River Basin in phases and batches; Intensify the control of soil erosion, and implement comprehensive treatment projects focusing on dam system construction in places where conditions permit; Accelerate the construction of the "Digital Yellow River" and provide an information sharing platform for the detection, prevention and control of water pollution in the Yellow River.

Industrial pollution has always been the main cause of water pollution in the Yellow River. From Qinghai, through Gansu and Ningxia to Inner Mongolia, there are many highly polluting industrial enterprises such as energy, heavy chemicals, non-ferrous metals, and papermaking along the Yellow River, producing a large number of pollutants including COD (chemical oxygen demand), ammonia nitrogen, heavy metals, permanganate index, and volatile phenols. Due to the large investment in environmental protection facilities and high operating costs, the phenomenon of illegal discharge of key pollution sources along the Yellow River is still relatively serious, and some "15 small" and "new five small" enterprises are multifaceted and wide, and it is difficult to do so.
The Yangtze River is the largest river in China, with beautiful scenery and many cities along the river. Nature has endowed the Yangtze River with abundant water, with an average annual runoff of about 1 trillion cubic meters, accounting for 36 percent of the country's total water resources. The main stream is a low-salinity river with good natural water quality, which is the source of life for the 400 million people in the basin and an ideal water area for the reproduction of aquatic organisms. >>>More

The water transport of the Yellow River can be traced back to 4,000 years ago, from the pre-Qin period to the Wei, Jin, Southern and Northern Dynasties, with Chang'an and Luoyang as the center, the Yellow River, the Wei River and the artificially excavated chasm constitute a water transport network. From the Sui and Tang dynasties to the Northern Song Dynasty, the Yellow River and the North-South Grand Canal, centered on Luoyang and Bianliang, pushed the water transportation of the Yellow River to a prosperous period. >>>More
