70,000 years ago, the early Homo sapiens in Ding Cun, Xiangfen, Shanxi Province, and the late Homo sapiens in Dagouwan, Uxin Banner, Inner Mongolia, 30,000 years ago played the prelude to the ancient Yellow River civilization.
The sites of microlithic culture from 10000 to 7000 years ago, Neolithic culture from 7000 to 3700 years ago, bronze culture from 3700 to 2700 years ago and ironware culture from 770 BC are almost all over the Yellow River basin. Since the Middle Stone Age, the Yellow River Basin has become the development center of ancient culture in China. Suirenshi, Fu and Shennongshi created and invented artificial fire technology, primitive animal husbandry and primitive agriculture, which opened the prelude to the development of the Yellow River civilization.
Qin Huang Hanwu, Tang Zong Song Zu, a generation of arrogant Genghis Khan, these emperors led the Chinese nation to push the ancient Yellow River civilization to the brilliant peak that attracted worldwide attention. Gunpowder, compass, papermaking, printing, Tang poetry and Song poetry, and Yuanqu are glittering treasures in the Yellow River civilization. Inventions and scientific achievements not only promoted the development of China, but also spread all over the world and promoted the progress of all mankind.
First, the second longest river in China.
The Yellow River, the second longest river in China, is a 5464-kilometer-long river that winds in the north of China. Seen from the sky, it is like a huge word "several", and it is also a unique totem of our nation.
Second, the characterization of the Yellow River
Not just a big river. The Yellow River, Yellow Earth, Emperor, Yellow Skin and the legendary dragon, all these yellow symbols sublimate this turbid stream flowing through the heart of China into a sacred river. Han Shu Gou Ji regards the Yellow River as the head of thousands of waters: "China has the source of all rivers, not in the four capitals, but in the river."
Third, the theory of loess weathering.
In a long geological time, in the desert Gobi in the interior of Asia, the sand everywhere is decomposed and crushed in the harsh environment of rapid cooling and rapid heating until it forms powder. The northwest airflow prevailing in the inland has blown them to the east for many years, and the coarse sand has fallen on the Mongolian plateau, and the most delicate powder has fallen to today's six provinces of Gansu, Shaanxi, Shanxi, Qinghai, Ningxia and Henan. After millions of years of transportation and accumulation, a loess plateau has finally formed, starting from the Great Wall in the north, reaching Qinling Mountain in the south, Sun Moon Mountain in the west and Taihang Mountain in the east.
Fourth, the deep and vast loess layer.
This is an unparalleled loess, with an area of 4 1 1,000 square kilometers, and the thickness of loess coverage is generally above 1 1,000 meters. The loess in Longdong, Shaanxi, Shanxi and other places is as deep as 100 to 200 meters, and the thickness in Lanzhou is more than 300 meters.
The Garden of Eden five or six thousand years ago.
Botanists have found that although the rainfall in the Loess Plateau is not as abundant as that in the south, there is less nutrient leaching, which is very suitable for the growth of poplar, birch, oak, Chinese pine, spruce, jujube and Vitex negundo. At that time, lush vegetation gave birth to a warm and rainy Garden of Eden. Today, Shanxi, Shaanxi, Gansu, Ningxia and other provinces have large areas of virgin forests. Henan Province, located in the Central Plains, is referred to as "Yu" for short. It can be seen that in the era of word-making in Cangjie, it was still a place where elephants haunted.
Seven, the enlightenment of ancient civilization
Charred animal fossils and antler fossils were found in Houdu human activity site in Ruicheng, Shanxi, more than 6.5438+0.6 million years ago, and many carbon deposits were found in Lantian human site in Shanxi, 6.5438+0.6 million years ago.
Since then, Lantian people, Dali people, Dingcun people and Hetao people have all thrived in the embrace of the Yellow River. Until 6000 years ago, matriarchal clan culture represented by Banpo civilization appeared on the yellow land.
Our ancestors hunted and gathered in such a green field and spent the golden childhood of Chinese civilization.
VIII. Historical account of achievements in transforming nature
It is indeed the first place to bathe in the light of civilization, and it must be the first place to be touched by the fire of civilization. According to ancient legends, Shennong once taught people to grow crops. What is intriguing is that Shennong is Emperor Yan, that is, Vulcan, and what he teaches is actually burning forests for farming. Mencius recorded the "merits" of the three emperors and five emperors burning the forest: "When Yao was in power ... the vegetation was lush, the animals were breeding, the grain was not harvested, and the animals were threatening ... Yao was worried and got it done. Make good use of fire. The fierce mountain burned it, and the animals fled. "
In the Book of Songs, we heard the ancestors chanting when they cut down trees: "Kan Kan cut sandalwood, the river is dry, the river is clear, and the blue waves are rippling." "When logging is tintin, birds sing." Nine, the loess plateau vegetation suffered great damage for the first time, and the emperor unified the six countries. A large number of people then entered Guanzhong, and the reclamation area increased greatly. At the same time, large-scale construction, the construction of the palace mausoleum, wantonly cut down the Guanzhong mountain forest. In the thirty-third year of the First Emperor (2 14 BC), Meng Tian defeated the Xiongnu and gained a large area of land in Hetao. Later, he settled in other places to defend the border and immigrated to the Ordos Plateau many times, with hundreds of thousands of people each time. The originally endless grassland has become a farming area.
XI。 Expose the bottom of the river
A few days ago, a century-old wonder "uncovering the bottom of the river" appeared in Dajinzui and Xiaoshizui sections of Shanxi Hejin section of the Xiaobei main stream of the Yellow River (Shanxi and Shaanxi sections), and the sediment at the bottom of the river was rolled up like a carpet by the current.
The phenomenon of "uncovering the bottom of the river" is a unique law of sediment movement in the Yellow River, which mainly occurs in Longmen, the main stream of Xiaobei, and Weihe, the tributary of the Yellow River. Its performance is that when the flood peak with high sediment concentration passes by, the riverbed is seriously washed in a short time, and the massive and flaky sediment at the bottom of the river is rolled up like a carpet, and then swept away by the current. Such intense scouring can make this section of riverbed several meters to more than ten meters deep in a few hours to dozens of hours. Due to the special conditions of the phenomenon of "uncovering the bottom of the river", "uncovering the bottom of the river" is called the century-old wonder of the Yellow River.
It is reported that the Yellow River was last "uncovered" on July 6, 1977 at/kloc-0. This "river bottom revelation" began at 8: 00 on July 5 and lasted until 8: 40. During this period, in the spur dike section of Xiaoshizui Reconstruction Project 1 in Hejin reach, two large-scale lifting objects 1 with a height of about 1 m and a length of about 7-9 m were hoisted successively with the turbulent underwater sound.
At the beginning of July, the tributaries from Wubao to Longmen in the middle reaches of the Yellow River were flooded with heavy rain, and the flood carried a lot of sediment south. On the evening of July 4th, the flood peak discharge of Longmen Hydrological Station at the source of Hejin reached 4600 cubic meters per second, and the maximum sediment concentration was more than 700 kilograms per cubic meter, which created conditions for the phenomenon of "uncovering the bottom of the river" in some areas.
Poetry of the Yellow River —— Ode to the Yellow River
Ode to the Yellow River is one of the movements of the Yellow River Chorus, which consists of three parts: overture, main body and ending. The songwriter is Guang William. J and the songwriter is Xian Xinghai.
Judging from the content, the first section is recitation, which is the prelude to the whole poem. The author first addressed the readers as "friends" by addressing them, and clearly stated the theme of "praising the Yellow River" at the beginning, which showed the greatness and strength of the Yellow River.
The second section is the lyrics, which is the main part of the whole poem, mainly Ode to the Yellow River, but there is a gaining stage before Ode. In this paper, the word "Wang" is taken as the commander-in-chief, praising the great spirit of the Yellow River. The main part consists of painting the Yellow River and praising it. Draw the Yellow River, draw the majestic momentum of the Yellow River and draw the heroic spirit of the Yellow River. Praise the Yellow River, praise the Yellow River for nurturing the Chinese nation, and point out its historical contribution; Praise is like defending the natural barrier of the Chinese nation, pointing out the geographical advantages of the Yellow River. Praise the vastness of the Yellow River basin, which is a symbol of our national spirit and inspires the Chinese nation. "ah! Yellow River! " It has played a very good role, one is to express one's feelings directly, and the other is to divide the "ode" part into three levels: praising the Yellow River for nurturing the Chinese nation, defending the Chinese nation and inspiring the Chinese nation.
The last part calls on us to learn the spirit of the Yellow River. On behalf of the people of China, the poet issued an oath to learn from it, learning from the great and strong spirit of the Yellow River, so that the whole poem echoed from beginning to end and was integrated.
In Ode to the Yellow River, the poet uses symbolism, ostensibly praising the Yellow River, but actually praising our nation, inspiring Chinese sons and daughters to be "great and strong" like the Yellow River and defending the Yellow River and China with heroism and strong determination. Her melody is passionate, the music is majestic, magnificent, passionate and deep, full of strong impact and shock, which shows the unruly blood of the Yellow River and the heroic spirit of the Chinese nation and praises the majestic momentum and long history of the Yellow River.
Ode to the Yellow River is an ode to the Yellow River, an ode to the times, an ode to the Chinese nation, and an ode to perseverance and perseverance of the Chinese nation.

Legends about the Yellow River
1- Legend has it that a long time ago, the ancient Yellow River was a wild horse that was difficult to tame. It runs as it pleases, like a grinning monster, growling day and night, devouring thousands of fertile fields. Bite Chung Shan Man, the Hui people on both sides of the Yellow River can only live a slash-and-burn life at the top of the mountain and at the bottom of the ditch. At that time, Ningxia was not a plain bordered by Ma Pingchuan, but green mountains and valleys. There is no flat field, and no field can be irrigated with Yellow River water. Legend has it that there are several families living in Niushou Mountain who return to the Han family. They carry water at the foot of the mountain and farm at the top of the mountain for generations. All ages are busy, but they don't have enough to eat and don't wear warm clothes. For a long time, no one could stand this torture. One year, a 70-year-old Hui Hui man named Del opened a melon garden on the mountain and planted some cucumbers. He gets up early every day and goes to the Yellow River to fetch water and water cucumbers. His shoulders are swollen and his feet are skinned. He carefully cultivated cucumbers, and the yellow ones looked tender and sweet. On this day, the old man was tired and fell asleep at the gate of the vegetable garden. As soon as he fell asleep, he dreamed that there was a white cloud floating in the sky. Gradually, Baiyun turned into an imam with a white beard, shook his silver beard and said to the old man, "There are two strong winds today, so you should pay attention. There is a yellow wind at noon, which can make cucumbers wither; There is a black wind in the afternoon, which can make cucumber stems fall off. No matter how windy it is, don't pick cucumbers. When the old man woke up, he saw that the white-bearded imam had disappeared, but he saw that the yellow wind in the north was overwhelming and suddenly blew to Niushou Mountain. The old man looked at the cucumbers carefully, and sure enough, they faded one by one. He was very sad. A year's efforts were in vain, but the thought of the white-bearded imam stopped him. In the afternoon, a black wind blew, shaking the earth and shaking the leaves layer by layer. When the old man saw that the cucumber was about to fall to the ground, he was very angry. He picked a cucumber and threw it into the Yellow River. The Yellow River immediately broke a line. As if he had been cut by a fairy with a knife, he clearly saw the bottom of the river. When the old man Gerd swooped down, the river suddenly joined again. The old man was tired and hungry, sitting on the river bank, blinking, and the golden flower danced wildly, knowing nothing. At this time, the old man in Del heard the white-bearded imam say, "This cucumber is the key to conquering the Yellow River. You can cut off the Yellow River and make it listen to people. But now the Yellow River is called Yellow Wind and Black Wind, and these two Iberians are suffering. Don't be impatient, be patient and work harder. Next year, you plant another cucumber garden. When the cucumber is ripe, you pick the biggest one and throw it into the Yellow River. At that time, you walked into the cave at the bottom of the river, took off your jewels, took away the seeds of grains, and had a sword to cut dragons and demons and tame the Yellow River. Where you point, the Yellow River water will flow. The next year, the hardworking old man Gerd planted another cucumber garden. He is not afraid of the long journey, and he does not hesitate to sweat like rain, carrying water from the Yellow River to water melons. Everything comes to him who waits. Finally, a three-foot cucumber grows in the garden, which looks like a key. The old man happily slept in the melon garden for a day and a night until the melon was ripe. On this day, the weather was fine, without a cloud. Old man Wilder picked a three-foot cucumber, read "Taismi" and threw it into the Yellow River. At this time, I only heard the roar of the Yellow River, and I opened a long crack. All the stones at the bottom of the river are clearly visible. When the old man went down to the bottom of the river, he saw a hole near the river bank, where pearls and agates were everywhere. The old man took some and just left, he heard the storm whistling. At that time, the waves on the river rolled and the waves became higher and higher. The old man Gerd picked up his sword and cut dozens of swords on the left and right sides of the black whirlwind and the yellow whirlwind. After a while, black wind and yellow wind blew in the sky. At this time, the faults of the Yellow River gradually tightened. Del's old man remembered the command of the white-bearded imam, and this sword could conquer the Yellow River. He knew very well, and he thought, I want the Yellow River to fill ditches and level mountains. Holding two swords, the old man plunged into the Yellow River, and the water in the Yellow River stopped flowing at once, as if a Great Wall had been blocked in front, but it was still rising steadily, which was really scary from a distance. Three days later, from Liupanshan in the south to Helan Mountain in the west, there was water everywhere, leaving only a few mountain tips. Only then, the old man, Gerd, drew his sword and told the Yellow River to flow forward. Since then, Ningxia, a deep mountain valley, has become Ma Pingchuan, and the Hui people living on both sides of the Yellow River have dug ditches for farmland with hard-working hands and lived a happy life.
2- Myth and legend: Dayu had three treasures when he governed the Yellow River. One is the river map; The second is a mountain axe; The third is to avoid water swords. Legend has it that the river map was given to Dayu by Hebo, the water god of the Yellow River. In ancient times, there was a man named Feng Yi in Huayin General Township. He is uneasy about farming and wants to become an immortal. He heard that people can become immortals after drinking the juice of daffodils for one hundred days. So I looked everywhere for daffodils. Before Dayu harnessed water, the Yellow River flowed to the Central Plains. There is no fixed channel, it flows everywhere and is often flooded. There are seven strands and eight roads on the ground, and the branches in the ditch are all yellow river water. Feng Yi ran around looking for daffodils, often crossing, crossing and dealing with the Yellow River. Ninety-nine days passed in the blink of an eye, and then I found a daffodil and sucked the juice of the daffodil for a day, so I could become an immortal. Feng Yi was so proud that he crossed the Yellow River and went to a small village to look for daffodils. The water here is not deep. Feng Yi waded across the river and reached the middle of it. Suddenly, the river rose. He panicked, slipped, fell into the Yellow River and was drowned alive. After Feng Yi's death, she was full of grievances and resentments and hated the Yellow River, so she went to the Jade Emperor to sue the Yellow River. The Jade Emperor was also annoyed when he heard that the Yellow River was undisciplined and wandering around, endangering the people. Seeing that Feng Yi had been sucking the juice of daffodils for ninety-nine days, it was time to become an immortal. He asked Feng Yi if he would be the water god of the Yellow River and govern it. Feng Yi was overjoyed. Full of promises. Now I can realize my dream of becoming an immortal, and secondly I can avenge my drowning. Feng Yi became the water god of the Yellow River and was called Hebo. He has never been involved in water control, and suddenly assumed the responsibility of managing the Yellow River, helpless and worried. What should we do? I have no magic weapon, so I have to ask the Jade Emperor for advice. The Jade Emperor told him that to manage the Yellow River well, we must first find out the water conditions of the Yellow River and draw a river map. Based on the river map of the Yellow River, it will be much easier to control the Yellow River. Hebo, according to the instructions of the Jade Emperor, was bent on drawing a river map. He went to his hometown first and wanted to ask the villagers for help. Everyone in the village hated his idleness and his work, and no one answered him. He found the old man in the village and expressed his great ambition to govern the Yellow River. When the old man saw that he was now a fairy and wanted to do something good for the people, he promised to help him. From then on, Hebo and later old people came and went in the rain, wading through mountains and rivers to see the Yellow River water regime. After running for several years, the old man was tired. After the old man only went back, the rest of Hebo continued to check the water situation along the Yellow River. When we parted, the old man repeatedly told Hebo that the director should go all the way and not give up halfway. After drawing the map, he began to manage the Yellow River, and there was not enough manpower. He persuaded the villagers to help. It is a hard job to check the water regime and draw a river map. By the time Hebo finished drawing the river map, he was old and weak. Hebo looked at the river map, where the Yellow River is deep and shallow; Where it is easy to explode, it is easy to explode; Where to dig and where to block; Where the water can be cut off and where the flood can be discharged are clearly drawn. I can only sigh that I have no strength to manage the Yellow River according to the map, which is very sad. Hebo thought that one day someone would come to harness the Yellow River. It will be worthwhile to give him the river map then. Hebo spent his old age under the Yellow River and never appeared again. Unexpectedly, the Yellow River overflowed again and again. People know that the Jade Emperor sent Hebo to control water, but they didn't see him. They all scold Hebo for not doing his duty, regardless of whether people live or die. The old man hasn't seen Hebo for several years after waiting for him every day in his hospital bed. He is uneasy about managing the Yellow River and wants to find Hebo. His son's name is Yi, and he shot every shot. No matter what the old man says, Yi won't let him go to Hebo. Later, the old man did not listen to his son's dissuasion. As a result, he met a breach in the Yellow River, was washed away and drowned, and even the body was not found. Hou Yi hated Hebo's guts and gnashed his teeth, saying that Hebo would be shot sooner or later. Later, Dayu came out to control water, and Hebo decided to give him the map of the Yellow River. On this day, Hebo heard that Dayu came to the Yellow River with an axe and a sword to avoid water, so he came out from the bottom with a river map to look for Dayu. Hebo and Dayu have never met before, and neither of them knows each other. Hebo walked for a long time and was so tired that he wanted to have a rest. He saw a young man crossing the river. This young man is a hero. He must be Dayu. Hebo shouted and asked, "Hello, who are you?" The young man on the other side is not Dayu, but Hou Yi. He looked up, and on the other side of the river, a saint-like old man was asking loudly, "Who are you?" Hebo said loudly, "I'm Hebo. Are you Dayu? " When Hou Yi heard that it was Hebo, he immediately rushed to his heart and sneered, "I am Dayu." Said the bow and arrow, don't ask, don't indiscriminate, "sou" an arrow, hit Hebo's left eye. Hebo pulled an arrow on his eye, and he was sweating with pain. He cursed in his heart: "Damn prison, how unreasonable!" The more he thought about it, the more angry he became, and he tore up the water map. Just then, there was a loud shout: "Hebo! Don't tear the picture. " Hebo barely looked at it with his right eye. On the other side, a man in a hat stopped Hou Yi. This man is Dayu. He knew that Hebo had painted a picture of the Yellow River and was going to ask Hebo for advice. Hou Yi pushed Dayu away and tried to draw a bow and arrow. Dayu grabbed him desperately and told Hebo about the hardships of painting. Hou Yi regretted his recklessness and shot Hebo in the left eye. Hou Yi and Dayu crossed the river together. Hou Yi admitted his mistake to Hebo. Hebo knew that Hou Yi was the old man's son and didn't blame him. Dayu said to Hebo, "I'm Dayu, and I've come to ask you for advice on how to manage the Yellow River." Hebo said, "My heart and blood and the way to manage the river are all on this picture. I will give them to you now." Look at Dayu's exhibition map, which is dense and dense, and draws the water situation of the Yellow River clearly. Dayu was extremely happy. He wants to thank Hebo. Looking up, Hebo jumped into the Yellow River and disappeared. Dayu got the hydrological map of the Yellow River and kept it around the clock. According to the instructions on the map, he finally managed to control the Yellow River.
