It is no exaggeration to say that the Yellow River is a river full of disasters. In the more than 2,000 years of historical records, more than 1,500 breaches and flooding occurred in the lower reaches of the Yellow River, and 26 major diversions occurred.
The lower reaches of the Yellow River with written records generally pass through Hebei Province, from the present-day Ziya River to the sea near Jinmen, and are called the "Old Yu River Course". The Yellow River changed its course for the first time in 602 BC until it changed its current course in 1855 AD.
During this period, 1128 years ago, the river ran north of the current river channel and entered the sea from Jinmen, Lijin and other places; later, it ran south of the current river channel, taking the Huaihe River and entering the sea. The disaster affected an area of about 250,000 square kilometers in the lower reaches of the Haihe River, Huaihe River and the Yangtze River.
Every breach caused heavy losses.
The Yellow River is a river with less water and more sand, with uneven distribution of water and sand. This feature is determined by the climate zone and geological-geographic environment in which the Yellow River basin is located. The main stream of the Yellow River is more than 5,400 kilometers long, with a drainage area of 750,000 square meters.
Kilometers, it spans dry, cold, arid, and semi-arid climate zones from west to east, and flows through the Qinghai-Tibet Plateau with an altitude of more than 4,000 meters, the Loess Plateau with an altitude of 1,000-2,000 meters, and the North China Plain with an altitude of 0-200 meters before entering the sea.
Floods in the lower reaches of the Yellow River have always attracted the attention of the world. Historically, the Yellow River has a saying that "it bursts twice every three years and changes its course once every hundred years." From the fifth year of King Ding of Zhou Dynasty (602 BC) to the 1938 Huayuankou breach in 2540
In 2016, there were 543 recorded years of breaches and floods, and more than 1,590 embankment breaches. The main river course experienced five major diversions and migrations. The floods affected Tianjin in the north and Jianghuai in the south, including Hebei, Shandong, Henan, and Anhui.
, the Yellow-Huaihai Plain in Jiangsu Province. 250,000 km2 across
The Yellow River is sometimes called "China's Worry" due to flood disasters. Floods often claim the lives of many people on both sides of the lower reaches. According to historical records, more than 2 million people died in 1887, about 3 million people died in 1931, and 50 people died in 1938.
Tens of thousands of people drowned. In 1938, in order to delay the advance of the Japanese army, the government blew up the Yellow River embankment at Huayuankou north of Zhongyuansu, resulting in a tragedy in which 890,000 people drowned and 12 million people became homeless.
There are both natural and man-made reasons why the Yellow River is so troubled and has become "China's worry".
First, since the Qin Dynasty, the temperature on the Loess Plateau has turned cold and heavy rains have concentrated. In addition, the loess itself has a loose structure and is easily eroded and collapsed, which has promoted soil erosion and caused a large amount of sediment to enter the Yellow River.
The second is the rapid growth of population. Unrestricted reclamation and grazing has destroyed forests, destroyed grasslands, and seriously damaged green vegetation. The Loess Plateau has lost its natural protective layer, causing serious water and soil erosion.
How to manage the Yellow River? Experts and professors in China have also tried their best, but they have never gone beyond afforestation and soil and water conservation. With the current level of science and technology and economic capabilities, they can only start from this point.
But facts have proven that this conventional governance method is not very effective. Not to mention the problem of how tens of millions of people in the upper and middle reaches of the Yellow River survive. Even if these tens of millions of people do not cut down a single tree, it is impossible to fundamentally change the situation.
Manage the Yellow River well. Because the Yellow River is a disaster, there are also deep-seated natural, climatic, and geological reasons.
However, the current strength of the people on earth or China is not enough to manage the Yellow River well, but it does not mean that Zhao Wuji cannot control the Yellow River either.
The "Xuanhe River" downstream is like a fertile land to Zhao Wuji's Yuandao Autonomous Territory. Although the sand deposited on the river bed is mostly "coarse sand" and lacks nutrients, as long as it is transported to Yuandao
, it can become mature soil with a little modification. It is much easier to organize than the mud and sand with salt and mineral components fished from the deep sea of the Pacific Ocean.
In fact, afforestation in the middle reaches can be changed to tree planting and grass planting, and the main industry is changed from agriculture to animal husbandry. In addition, necessary slope management and necessary water conservancy facilities are added. Presumably, in ten or twenty years, the Loess Plateau will be
Change appearance.
The first step in the management of the Loess Plateau in the midstream is large-scale investment. This kind of investment is an investment in environmental management. It is only investment but has no direct return. This is difficult to achieve under China's current system.
Why are rivers and streets in Chinese cities so easy to renovate? The reason is not that the government has money, but that the money can quickly produce more money after being invested. For example, a square in Pingyuan City was opened in just a short time.
In the past thirty years, it has been renovated five times on a large scale, and countless amounts of money have been wasted.
The second step in the management of the Loess Plateau in the middle reaches is the use of new technologies. This is not a problem for Yuandao. The plant varieties, biotechnology, management plans, etc. related to the Loess Plateau are basically all existing.
The third problem is relatively more troublesome, which is the problem of industrial transfer. Because after returning farmland to forest and planting trees and grass, the industrial form based on agriculture will give way to the industrial form based on animal husbandry, and the form of animal husbandry will
The population carrying capacity is preferably 3-5 people per square kilometer, which means that in the entire Loess Plateau of 400,000 square kilometers, a maximum of 2 million people make a living from animal husbandry. However, the traditional industrial form based on agriculture has the smallest population.
All have more than 30 million people.
In addition, the ecology of the upper reaches of the Yellow River and the entire northwest region is very fragile, which is also an issue that must be considered in the management of the Yellow River.
"Xiao, what do you think we should do to coordinate the management of the Yellow River with the management of the entire northwest region?" Zhao Wuji couldn't let go after thinking about these issues.
As the saying goes, the greater the ability, the greater the responsibility. Zao Wuji has a deep "consciousness" about this.
[Lord, it would be best if you could consider the northwest region. Do you know why the "Shenchuang Base" is hidden in the Kunlun Mountains in the northwest? Because Kunlun Mountain is where the ancient powers collectively left for the Shenchuang Galaxy? 】
"What do you mean?" Zhao Wuji felt that there was something unknown in the provocative words.
[Because northwest China is the most convenient area for contact between the earth and alien planets, the legends of Kunlun Mountain and Lop Nur spread in China, as well as the ancient civilizations that disappeared in the desert areas, all imply this conclusion. 】
"I'm afraid this is a bit far-fetched." Zhao Wuji didn't believe it.
[Far-fetched? Lord, do you think the "Yuanyang Zhenqi Jue" you practice is fake, or is the "Shenchuang Base" fake? Or do you think life is all illusory? 】
"..." Zhao Wuji was speechless. In fact, although Zhao Wuji was successful in cultivation and mastered a heaven-defying weapon like the "Shenchuang Base", he still instinctively separated reality from legend.
Perhaps, this is also a portrayal of "it's easy to change a country, but it's hard to change one's character".
[Do you know why China has the highest success rate of satellites launched from the northwest region, while other countries have more or less failures? Do you really think that China’s rocket technology is more developed than Western countries? 】
"Why?" Needless to say, Zhao Wuji was also very interested in this question.
[This is very complicated to say, but to simplify it into one sentence, the northwest region of China is the region least disturbed by star power lines; and in ancient times, it was also the region with the strongest aura. 】
"What does the star force line mean?" Zhao Wuji still grasped this key very sensitively.
[Everyone on earth now knows the concepts of magnetism and gravity, and the star force line is the final resultant force of all the magnetism of a planet and the mutual gravity between the planets. The range where the force is located is the star force line; it is least affected by the star force line.
This does not mean that there is no such combined force in the area, but it means that this combined force is the most stable. In one word, it is called calm and less prone to accidents.】
"Then what does the northwest region have to do with the ancient spiritual energy?"
[Aura is a kind of advanced energy, which can also be understood as active energy. It is not easy to accumulate in areas with chaotic magnetism and gravity. However, it can only be accumulated on a large scale in areas where the star force lines are relatively stable. 】
"Then why is it now a desert?"
[This, there is no record of the divine creation civilization. However, according to the experience of other similar civilizations, the changes in climate and environment in the northwest region may be related to the great power in ancient times. You must know that with your ability, Lord, you can already
Changed the climate and environment.]
"You mean that the environment in the northwest region was intentionally caused by some powerful force?"
【This is very possible.】
"But didn't the scientists say that?" Zhao Wuji still didn't believe it.
[Lord, what is the knowledge of earth scientists? When a galaxy is formed, its rules have already been formed. For example, the earth rotates around the sun, and its period and trajectory are fixed. This is dynamic balance, and everything is like this.
.
Even if there are changes, they are just like the previous ice ages and the Little Ice Age on the earth, and are within the scope of human understanding and tolerance. But when a place changes from a forest oasis to a desert, either a vicious event such as Mars hitting the earth occurs, or
This was done deliberately by powerful men like the ancient monks.】
"Xiao, what do you mean when you say this?" Zhao Wuji is not stupid at all. Since Xiao emphasized so much, if he wants to go into outer space in the future, the northwest region must be the best starting point.
[Management of the Yellow River can be used as a starting point to gradually include the northwest into the plan. If earth civilization wants to go into space, it must start from the northwest!]
How could Zhao Wuji not know the importance of the northwest? Western Xinjiang alone occupies one-sixth of China's land area. If the Qinghai-Tibet region is included, the entire northwest's land area accounts for more than two-thirds of China's area, and
The population and productivity, etc., only account for less than one-fifth of China's or even less.
It is the same as the management of the Yellow River. If the ecological and environmental problems in the northwest are not solved, just like the rural problems are not solved, how can we talk about modernization and how can we talk about the "utopia".
[Lord, you must also understand that the northwest is the ultimate way to solve China's population pressure! The population carrying capacity of agriculture and animal husbandry is limited, but the population carrying capacity of modern industry and the future space industry is unlimited! 】
