Zhao Xi opened his arms and raised his head, letting the morning light stretch his figure long and long, and reflected it on the top of the mountain ridge. Zhao Xi, who blended into the morning light, was shrouded in light, making Su Song and others feel a kind of sacredness...
····
"Shi Deyi told the magistrate of Tongzhou to build a temple on the top of this mountain ridge, and asked Zhao Qin for money and food..."
It's inexplicable. This kind of official decree makes people feel inexplicable. In fact, this whole journey is a bit inexplicable.
To the west of the mountain ridge, there should have been Cangshan Town, but looking at it now, it is just a plain that is either deserted or cultivated. No one knows what Zhao Xi is feeling, maybe he is really feeling the morning light...
"Zirong, the Yellow River flows south from Puzhou, and the place where the Wei River merges into the Yellow River should be the most suitable place in Guanzhong to build a spillway, and the terrain is also the most suitable."
"However, the management of the Yellow River is rooted in sand control. I know this, so I focus on promoting carbonization and avoiding deforestation in the upper reaches as much as possible to conserve water and soil."
"Considering the middle and lower reaches, building a flood outlet at the mouth of the Wei River into the Yellow River can solve the problem of flooding in the lower reaches of the Yellow River to a certain extent..."
Su Song knew that there would be a turning point in the future for the officials. Su Song had to admit that he and Shen Kuo, including all the survey officials, believed that the place where the Wei River entered the Yellow River was the most suitable place to build a floodway. They even secretly reported to the officials.
This is also what was suggested.
We have the right to report secretly on many things in Gongfang City. It not only provides reference for the officials, but more importantly, the officials must decide on the information on various resources that have been surveyed, and the officials must decide on mineral resources.
development status.
When the officials put forward their suggestions, under such circumstances, they knew that the officials were about to turn a corner.
"I agree to build a floodway here. However, I ask you to comprehensively consider the cultivated land in the Guanzhong Plain, fully consider the connection between the Guanzhong Plain water system and the floodway, and fully consider the consequences of the amount of sand carried by the Yellow River."
"The Yellow River carries sediment and discharges it, which will inevitably cause a large amount of sediment to enter the spillway with the water flow. If things go on like this, alluvial land will be formed, and even sediment backflow will be formed, which will eventually affect or even destroy the fertile farmland of the Guanzhong Plain!"
"Gyeonggi Road and Jingzhao Prefecture are all people of the Song Dynasty to me. Even though part of the fertile land in Jingzhao Prefecture is sacrificed, the benefits to Jingxi Road, Gyeonggi Road and even Jingdong Road are more than the loss to Jingzhao Prefecture, but I still
Don’t want to do this.”
This is the tangle in Zhao Xi's heart.
In later generations, when he originally lived, there was a majestic dam where the Wei River entered the mouth of the Yellow River. It was because of this dam that he moved to Cangshan Town...
This matter had been debated for decades even in the era in which he originally lived.
Less than a year after the dam was built, a large amount of sediment accumulated in the Weihe River Basin, the river bed was raised, large areas of fertile farmland were submerged, and the land rapidly became salinized, making it as dangerous as Xi'an at that time.
We had no choice but to lower the water level, dismantle the 150,000-kilowatt generator set, and refit a 50,000-kilowatt small unit. At the same time, it cost an astonishing amount of manpower, material and financial resources to open drainage holes to drain away the sediment. As a result, no less than 10 billion yuan was invested in the reservoir."
Drilling ditches".
Many farmers who had lived in the Weihe Plain for generations had to leave their homes and migrate to water-scarce areas in Ningxia. At first, Zhao Xi's parents, because it was difficult to leave their homeland, settled an entire town west of this mountain ridge.
At that time, he often listened to the narratives of the older generation...
Zhao Xi didn't know if his dreams these days were related to what was about to happen in the future, but when he really had to make a choice about this matter, he struggled for a long time... There was a big difference between this time and later generations. Loess
Soil erosion on the plateau is not as serious as it would be in later generations.
Su Song listened for a long time, but couldn't understand what the official meant.
How should I put it? Since we agreed to build a floodway where the Wei River merges into the Yellow River, we were reminded that the sediment in the Yellow River might destroy the farmland in Jingzhao Prefecture, and we didn’t want the people of Jingzhao Prefecture to be harmed...
··How can there be such a solution?
"Zirong, when I entered the Wei River, I talked to you about the eight rivers that go around Chang'an. You also know that the eight rivers of Wei, Jing, Feng, Lao, Lao, Pou, Chan, and Ba form a continuous loop around Chang'an.
water system."
"So, I thought, if we make full use of the gullies formed by the alluvial accumulation of these eight days of rivers, based on these gullies, we can use manpower to penetrate all the ravines in the Guanzhong Plain, and finally connect them with the Yellow River, so as to serve as the floodway of the Yellow River. At the same time, in
The Guanzhong Plain forms a cyclic flood discharge system like the Eight Rivers in Chang'an."
"At the same time, select a suitable area to communicate with the spillway and the Chang'an Eight Rivers in a Doumen pattern, thereby forming a regulatory communication between the Yellow River water and the Chang'an Eight Rivers, and use the eight water flows to wash away the sediment in the Yellow River Spillway, so as to achieve
Artificial adjustment and balance of sediment alluvial accumulation."
"After this operation, I think it can not only solve the problem of Yellow River flood discharge, but also reduce to a certain extent or even avoid the damage to the fertile farmland in the Guanzhong Plain. At the same time, using the floodway to introduce the Yellow River can promote irrigation in the Guanzhong Plain and promote
The matter of mulberry farming in the Guanzhong Plain."
Perhaps it can be said that Zhao Xi had a sudden inspiration, or it may be that he has been thinking about it for decades. Zhao Xi made such a decision not only to solve the problem of flooding in the Yellow River in this era, but also to leave the terrain created by this floodway
And records serve as a warning for the original future and future generations.
Thousands of years of so-called vicissitudes and alluvial discharges from the Yellow River will inevitably change the topography of the entire Guanzhong Plain. As long as records are left, we can tell future generations that we have such experiences and lessons in deciding matters related to the Yellow River.
Perhaps Zhao Xi wants to avoid the pain of migration for those people who don’t know whether they exist or who can’t tell whether they are his descendants or their parents’ generation...
Su Song didn't understand Guan Jia's inner thoughts, but he completely understood what Guan Jia meant.
How should I put it? Although the eight rivers surrounding Chang'an do not really form a water system as the officials say, they are interconnected. At least the Wei River is the main river into which the eight rivers of Chang'an merge.
However, the idea proposed by the officials, whether it is really connecting the eight rivers or building the Yellow River floodway, is really ambitious.
This grandeur does not mean the grandeur of the project, but the grandeur of the layout.
There is no completely flat plain. The so-called Guanzhong Plain naturally has ravines and ravines. Make full use of these terrains to build a floodway... and then communicate with Chang'an Bashui... Su Song didn't even know it.
How did the officials come up with the idea?
Anyway, he doesn't have such wild and unconstrained thinking at all.
Su Song was a little excited. Standing on this mountain ridge, even though the Guanzhong Plain was right under the mountain, he still couldn't see clearly the distance beyond his sight.
