Introduction:
The Yellow River is a big river in the north of China, with a total length of about 5,464 kilometers and a drainage area of about 752,443 square kilometers. The fifth longest river in the world and the second longest river in China.
The Yellow River originated in Maqu, Yuegu Zonglie Basin, at the northern foot of Bayan Kara Mountains in Qinghai Province, and it was zigzag. It flows from west to east through Qinghai, Sichuan, Gansu, Ningxia, Inner Mongolia, Shaanxi, Shanxi, Henan and Shandong provinces, and finally flows into the Bohai Sea.
The middle and upper reaches of the Yellow River are dominated by mountains, while the middle and lower reaches are dominated by plains and hills. Because the middle section of the river flows through the Loess Plateau in China and carries a lot of sediment, it is also called the river with the largest sediment concentration in the world. However, in the history of China, the diversion of the lower Yellow River has brought great influence to human civilization. It is the most important birthplace of Chinese civilization, and China people call it "Mother River". Almost1600 million tons of sediment is produced every year, of which1200 million tons flows into the sea, and the remaining 400 million tons remain in the lower reaches of the Yellow River for many years, forming an alluvial plain, which is conducive to planting.
Question 3: What are the complicated estuaries after the Yellow River was diverted in history? I'll give you a website to read for yourself.
Historically, the Yellow River is famous for its good siltation, determination and good luck. The changes in the lower reaches of the river are extremely complicated. From Jin Dream to Xingyang (South Bank) and Wuzhi (North Bank), because the river is constrained by the South Bank Mountains, it only moves very little in the direction from west to east. The ancient city of Jin Meng is12.5km north of the city, and the ancient Yellow River is even north of the ancient city of Jin Meng. Now the Yellow River is only 2.5 kilometers away from Jin Meng. It can be seen that this section of the river has moved southward by about 10 km. Below Wuzhi and Xingyang, the Yellow River officially entered the North China Plain and changed its direction on a large scale. The shunt is not only frequent, the flow path is disordered, but also the coverage is very wide. There are dozens of rivers in history, like the ribs of folding fans. Wuzhi and Xingyang are fan buttons, and the fan bones are distributed to Haihe River in the north and Huaihe River in the south. The diversion of the Yellow River has a great influence on the geomorphological changes in this vast area.
According to the literature, from the pre-Qin period to about 3000 years before liberation, the lower Yellow River burst 1593 times, twice every three years on average, with 26 important diversions. Hu Weiwei, a beginner in Qing Dynasty, collated and summarized the records of thousands of diversions of the Yellow River in ancient times, and put forward five migration theories in Gong Yulue. After the fifth year of Xianfeng (1855), the copper tile compartments burst and diverted, and together with a migration, they were called "six major migrations". Coupled with the primitive old road before the early Warring States period, it can be summarized into seven stages. It is described as follows:
1, the river course before the early Warring States period.
The "Yu He River" in the lower reaches of the ancient Yellow River, as seen in the pre-Qin literature, is also known as "Gong Yuhe". The narrative in the chapter of "Water Guide" is "Loving me in the East". As for the heavy precipitation of Sanghuai, as for the mainland; It is also broadcast to the north as nine rivers, just like going against the current into the sea. "'Luo I' is the place where Luoshui enters the river, and' big umbrella breaks deep valley O' means that the ancient river flows from the northeast of the northern foot of Guangwu Mountain in Xingyang, Henan Province to the southwest of Xunxian County, and then goes north along the eastern foot of Taihang Mountain." Precipitation "means getting water, and" mainland "refers to the mainland. It shows that the great river is in the south of quzhou county today, receiving Zhangshui from west to east, and then going north to Lu Ze. "Nine rivers" refers to the majority, which refers to the formation of the lower reaches of the Yellow River wandering in the central Hebei plain. "Against the River" is the backward flow of tidal water from the estuary, which enters the sea in the southeast of Tianjin today.
Another river in the lower reaches of the Yellow River in ancient times was found in the pre-Qin literature "Mountain Classics", which was ignored by the world because there was no record of river runoff in Mountain Classics. In recent years, Tan Qixiang based on Beishan Jing? The Three Classics of Northern Dynasties records rivers, lakes and seas. What's the difference between them and Hanshu? It is found that after Gong Yu flows to Shenxian County, Hebei Province, "crossing the mountain and crossing the river" diverges from there and flows northward to meet the water, then flows northward to the south of Lixian County to meet the water A, then flows northward to Qingyuan County and eastward to Tianjin.
Yellow River Channel 2, the channel from the middle of the Warring States Period to the end of the Western Han Dynasty.
The third article found in the literature of the lower Yellow River is Hanshu? Geography and Hanshu? The river of the ditch, that is, the water classics? "The river is so secular" in River Notes. Hu Weiwei said: "Five years ago (602 years ago), the river moved eastward from Xukou to Luochuan, to the right of Huatai City, to the south of Liyang County in the northeast, to Liangcheng County in the northeast, and to Changshou Jin in the northeast. So the river left Luochuan and entered the sea in the northeast. " The water mirror is called "the river is so blasphemous" and is considered to be the first diversion of the Yellow River after Dayu's flood control.
The specific runoff of this "big river" is as follows: the section above Suxukou, which is the same as the river course, flows from the northeast of Suxukou to Changshoujin (now northeast of hua county, Henan Province), which is described in detail by Hu Weiwei; After Changshoujin, the river flows northward, so far to the northeast of Guantao County, south of Gaotang County in east longitude, and then to the west of Dongguang County to meet Zhangshui, and then to the northeast through Hanzhangwu County (now Fuyi City in Huanghua County) and eastward into the sea.
Tan Qixiang's textual research shows that although it is not credible to say that this river started from the five-year migration of King Ding of Zhou, the formation of this "great river is so common" is likely to be earlier than that of Gong Yu and the rivers with mountain views. Long-term coexistence during the Spring and Autumn Period and the Warring States Period became the main. Around the 1940s, Qi, Zhao and Wei built dams on the east and west banks of the river for hundreds of miles respectively. After that, the rivers in Gong Yu and Shanjing were cut off, and the rivers in Han Zhi continued until the Han Dynasty.
In the mid-Warring States period, the lower reaches of the river were diked in an all-round way, which played the role of flood storage and sediment retention, so the riverbed was relatively fixed. In the meantime, although it has definitely overflowed for nine times, the most famous one is that in the third year of Han Yuanguang (BC 132), "The river was decided by the scorpion (>>.
Question 4: Why does the Yellow River flow into the Bohai Sea in the history books? Because the Yellow River has been diverted many times, the estuary has changed many times.
Historically, the rivers in the lower reaches of the Yellow River changed from Haihe River in the north to Jianghuai River in the south. According to historical documents, the lower Yellow River burst 1500 times and changed its course more than 20 times.
The Yellow River is a big river in the north of China, with a total length of about 5,464 kilometers and a drainage area of about 752,443 square kilometers. The fifth longest river in the world and the second longest river in China.
The Yellow River originated in Maqu, Yuegu Zonglie Basin, at the northern foot of Bayan Kara Mountains in Qinghai Province, and it was zigzag. It flows from west to east through Qinghai, Sichuan, Gansu, Ningxia, Inner Mongolia, Shaanxi, Shanxi, Henan and Shandong provinces, and finally flows into the Bohai Sea.
The middle and upper reaches of the Yellow River are dominated by mountains, while the middle and lower reaches are dominated by plains and hills. Because the middle section of the river flows through the Loess Plateau in China and carries a lot of sediment, it is also called the river with the largest sediment concentration in the world. However, in the history of China, the diversion of the lower Yellow River has brought great influence to human civilization. It is the most important birthplace of Chinese civilization, and China people call it "Mother River". Almost1600 million tons of sediment is produced every year, of which1200 million tons flows into the sea, and the remaining 400 million tons remain in the lower reaches of the Yellow River for many years, forming an alluvial plain, which is conducive to planting.
Question 5: The birthplace of the Yellow River is (); The estuary of the Yellow River is (), and the province is (); Into the sea; Full length (); The Yellow River originates from the Yuegu Zonglie Basin at the northern foot of Bayankala in the Qinghai-Tibet Plateau.
The Yellow River Estuary is located in Huanghekou Town, Kenli County, Dongying City, Shandong Province. Located at the intersection of Bohai Sea and Laizhou Bay, the Yellow River was diverted in 1855.
Qinghai, where the Yellow River is located.
The Yellow River flows into the Bohai Sea.
The total length is about 5464 kilometers.
The dividing points of the upper, middle and lower reaches of the Yellow River are Longyangxia and Huayuankou.
Known as "Jiangnan" is Ningxia.
Question 6: Where does the Yellow River originate and where does it enter the sea? The Yellow River originates from the Kariqu Valley at the foot of Geziya Mountain at the northern foot of Bayan Kara and the Yogu Zonglie Basin, and is divided into two sources: north and south. 1978, when the state once again organized relevant units to conduct a more detailed investigation, it once again affirmed that Kariqu was the positive source of the Yellow River. The altitude of the two places is about 4600 meters to more than 4800 meters.
Kariqu, the original meaning of Tibetan is copper-red river. It is located at the foot of Geziya Mountain at the northern foot of Bayan Kara, with an altitude of 4,830 meters. Its source is five Koizumi flowing from a ditch on the hillside. The original river is just a gurgling stream, about 1 m wide and less than 1 m deep. This stream flows from southwest to northeast from the flat and narrow Kariqu Valley, and receives many tributaries, large and small, along the way, and gradually merges into a small river with a width of about 10 m and a depth of about 1 m.. The Kariqu River is crystal clear, and there are countless Haizi of different shapes and sizes on both sides. This river passes through a canyon of more than 65,438+000 kilometers, joins the Yogu Zonglie at Bayan River Mountain and flows into Maqu River.
Yogu Zonglie, the original Tibetan language, means a pot for frying highland barley. This is an image name given by local Tibetans according to the terrain here. Yogu Zonglie is an oval basin 40 kilometers long from east to west and 60 kilometers wide from north to south, surrounded by mountains. There are more than 100 small pools in the basin, which look like countless sparkling pearls embedded in the basin from a distance. Around Shui Bo, there are natural pastures with lush green grass. In the southwest of the basin, about 30 kilometers away from Yaradze Mountain, there is a Koizumi with an area of 3-4 square meters. The clear spring water keeps pouring, rolling and gurgling. The gushing spring water merges with countless trickles oozing from the basin, and gradually forms a gurgling stream with a width of about 10 meter and a depth of about half a meter. Moon Valley School was listed in Xinghai, and after merging with Kariqu, Maqu, the original channel at the source of the Yellow River, was formed. Maqu is called Peacock River by local Tibetans. In this section of the river, the river is wide and shallow, and the flow rate is slow, thus forming a large swamp and grass beach and numerous Shui Bo. Climbing high and overlooking, I saw countless Shui Bo shining in the sun, just like a proud peacock. Maqu flows eastward through the valley 16 km long and flows into the famous Xinghai.
Xinghai is a narrow basin slightly smaller than Guzonglie, with a length of more than 30 kilometers from east to west and a width of 10 kilometers from north to south. In this small basin, there are countless Shui Bo and Haizi of different sizes and shapes, the largest is several hundred square meters, and the smallest is only a few square meters. At first glance, it looks like a shining mirror, inlaid on a jade-like jade plate. After Maqu River arrived here, it merged into these scattered Shui Bo and Haizi, and it was impossible to tell which was the river course and which was Shui Bo. When the weather is fine, Shui Bo and Haizi, big and small, come one after another, just like the stars in the sky falling in a basin. There has been such a description in Xin Ning Fu Xin Zhi: Xinghai looks like a gourd, with a mouth in the east and a mouth in the west, Wang Yang in the north and south, and a series of chaotic springs in the northwest, which are connected into a whole and shaped like pomegranate buds. Every month, the moon is full of hope, the sky is clear, and Dongshan floats on the moon. As far as the shore is concerned, there are ice mirrors pouring out of Wang Yang, and hundreds of millions of spring eyes are hidden in it, like pearls of different sizes pouring into a plate of jade. Xiaoyan, the wind rises and waves return, wrapped in white and dazzling, which is really a wonder beyond the Great Wall.
The Yellow River flows through Xinghai and continues to flow eastward for more than 20 kilometers, accepting tributaries along the way, forming a river with a width of 6-7 meters and a depth of more than 2 meters, and then entering a vast Pingchuan, where two huge lakes are formed. This is the largest lake in the upper reaches of the Yellow River-Zhaling Lake and Eling Lake.
Finally, it flowed into the Bohai Sea, often diverted in ancient times, encroached on the Huaihe River and poured into the Yellow Sea.
