Recently, Zhang Jinliang, chairman of the Yellow River Survey, Planning and Design Institute Co., Ltd., announced to the public that the Yellow River is expected to be navigable, and the navigation of the Yellow River has been written? Ecological Protection and High-quality Development in the Yellow River Basin? In the top-level planning, the Henan Provincial Party Committee and the provincial government attach great importance to this and organize relevant departments to conduct in-depth research. This news sparked a heated discussion. Many netizens questioned that after so many years, the Yangtze River has been open to navigation for a long time, but the Yellow River has been closed to navigation. I think there are several reasons why the Yellow River is not navigable.

First of all, I think the main reason why the Yellow River has not been navigable is that there is too much sediment in the Yellow River. The Yellow River originated in Bayan Kara, Qinghai-Tibet Plateau. At first, it was just a slow and clear stream. It reaches the middle reaches of the Yellow River and flows through the Loess Plateau. Due to the lack of vegetation cover, a lot of rain will wash a lot of sediment into the Yellow River in rainy season. As we all know, the Yellow River has the largest sediment concentration in the world, with an annual sediment discharge of 65.438+0.6 billion tons. A large amount of sediment siltation blocked the riverbed. Although the country has been using dredging boats to clean up the sediment in the lower reaches of the Yellow River for many years, it has not been able to solve this blockage problem so far, and the riverbed is blocked, which makes navigation impossible.

Secondly, I think the reason why the Yellow River has not been navigable is because the upper reaches are narrow. The Yellow River is the second longest river in China. It flows through nine provinces and regions in several shapes, and the upper reaches are mainly mountainous. The upper reaches of this river are very narrow and the water is too shallow. Although some rivers are navigable, they are only used by small fishing boats, and large and medium-sized ships are impassable, so the Yellow River has been navigable.

Thirdly, I think the reason why the Yellow River has been unable to navigate is the problem of icing. The Yellow River flows upstream from its source to Hekou Town in Inner Mongolia. We all know that Inner Mongolia is prone to ice flood because of its high latitude, cold climate and long freezing time in winter. These harsh environments make the Yellow River navigable.

Fourthly, I think the reason why the Yellow River has not been navigable is that the navigation channel is too high. When the Yellow River reaches the lower reaches, the water flow is gentle, the river surface is wide, and a large amount of sediment is deposited on the Yellow River channel, gradually forming the ground? Hanging river? . The riverbed of the Yellow River is much higher than the dam of the city, and such a high riverbed also increases the navigation difficulty of the Yellow River.

In view of these problems, all countries are concerned. I believe that in the near future, we will be able to solve these problems and finally realize the navigation of the Yellow River. ?
