Which province is the source of the Yellow River?

The Yellow River originates in Qinghai Province.

Natural factors: The middle reaches of the Yellow River flow through the Loess Plateau, with loose soil and sparse vegetation. The precipitation in this area is small and concentrated. In the face of heavy rain, sediment and river water rushed into the Yellow River, making it the largest river with sediment concentration in the world.

When the lower reaches of the Yellow River enter the plain area, the water flow slows down, and the river carries a lot of sediment, which silts up the riverbed and forms an overground river. The riverbanks on both sides of the river are in danger of bursting at any time and place when encountering heavy rain, which is the most difficult river to control in the world. Harnessing the Yellow River focuses on soil and water conservation in the loess plateau in the middle reaches.

Man-made factors: human beings cut down trees in the upper reaches (Loess Plateau), resulting in soil erosion.

Extended data:

The sunshine conditions in the Yellow River Basin are abundant in China, and the annual sunshine hours generally reach 2000 ~ 3300 hours. The annual sunshine percentage is mostly between 50% and 75%; The sunshine is the most abundant, second only to the Qaidam Basin, but generally about L times more than the vast area of the Yangtze River basin south of the Yellow River.

The total solar radiation in the Yellow River basin is moderate in China, with the area north of 37 north latitude and the plateau area west of103 east longitude between 130 ~ 160 kcal/cm2. Most of the rest areas are 1 10 ~ 130 kcal/cm2. Although it is not as strong as the southwest, especially the Qinghai-Tibet Plateau, it is stronger than the northeast and south of the Yellow River in general, and it is a strong radiation area in East China.
