History, geography, customs, legends, poems, stories, articles, protection and humanities of the Yellow River

The total length is 5,464 kilometers, the source is 4,800 meters above sea level, the average flow is 1, 774.5 cubic meters per second, and the drainage area is 752,443 square kilometers. The source of Qinghai Province flows into the middle and lower reaches of the Bohai Sea. The demarcation point is the estuary, old Jin Meng, or the birthplace of the south of the Yangtze River: the natural scenery at the northern foot of Bayinkala Mountain in Qinghai Province. The Yellow River, the second longest river in China, originated in Bayan Kara, Qinghai Province. The main stream runs through nine provinces and regions, and flows through Qinghai, Sichuan, Gansu, Ningxia, Inner Mongolia, Shaanxi, Shanxi, Henan and Shandong, with a total length of 5,464 kilometers, a drainage area of 750,000 square kilometers, an annual runoff of 57.4 billion cubic meters and an average runoff depth of 79 meters. However, the water volume is not as large as that of the Pearl River, and there are 35 main tributaries along the way. The larger tributaries are in the upper reaches, with Huangshui River, Taohe River, Qingshui River, Fenhe River, Weihe River and Qinhe River in the middle reaches, and Yihe River and Luohe River in the lower reaches. There are no lakes on both sides of the river, and the lower reaches of the Yellow River are very small, and few rivers flow into the Yellow River. The estuary of the Yellow River is1500m wide, generally 500m, the narrower part is only 300m, and the water depth is generally 2.5m.. In some places, the depth is only 1.2 ~ 1.3 meters.

The vibrant upstream reach-this reach is called the "rich mining area" of the Yellow River's hydraulic resources. Among them, from Longyang Gorge to Qingtongxia, rivers and canyons alternate with each other, with large riverbed gradient and rich hydraulic resources. The planned utilization gap exceeds 1.200m, and the installed capacity exceeds1.0 million kilowatts, accounting for nearly 50% of the whole river. The average annual power generation is nearly 60 billion kWh.

The tender and lingering Ningmeng reach-the Yellow River flows peacefully here, irrigating the farmland on both sides and benefiting the local people. Therefore, there is a saying that "Huang Hefu and Ningxia are the best in the world" and "the Yellow River risks only one side is rich". The land near Yinchuan, Ningxia is flat and has a vast area. For more than 2000 years, the Yellow River has been used for gravity irrigation. There are abundant products here, and the precious Chinese herbal medicines Lycium barbarum and Yinchuan rice are of good quality, which is known as "Jiangbei". Photo of Lycium barbarum The Hetao Plain in Inner Mongolia is very dry. In the west, the annual precipitation is less than 200mm. Here, "no water is a desert, and water is an oasis". The Yellow River water has created superior conditions for industrial and agricultural production here.

The middle reaches of the Yellow River-Shaanxi-Gansu-Ningxia Gorge, where the Yellow River splits the Wan Ren Mountain like a bamboo, forming the longest continuous canyon section on the Yellow River. There are two famous places in this paragraph:

Hukou Waterfall-The Yellow River rushed here with thunderous momentum and roared away. Hukou Waterfall is not only a symbol of the Yellow River, but also a symbol of the Chinese nation's indomitable spirit of pioneering and forging ahead. The majestic song "The wind is roaring, the horse is roaring, the Yellow River is roaring, and the Yellow River is roaring" sings the elegance of the Yellow River, and even sings the heroic spirit of the Chinese nation's invincible and hard struggle.

Longmen-The story of "Carp yue longmen" originated from this. It is said that carp can jump over the dragon gate and become a dragon. This legend expresses people's good wishes to reach their ideal state after hard work, and also inspires Chinese children to strive for self-improvement and struggle. According to legend, it is a canyon dug by Dayu, so it is also called Yumenkou.
