"And, most importantly, soil erosion is so severe that the banks of the levees are vulnerable and can be destroyed in a single flush. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ”

Gao Shilian stroked his beard and asked, "Then I don't know what the solution is, build water conservancy?" ”

Du Ruhui also expressed his opinion: "Strengthen the river dam!" ”

Bai Liyun nodded and said: "Yes, strengthen the river dam, build water conservancy, divert and relocate, and improve the water conservancy system." However, these are only palliative, not the most important. You know, in fact, the main cause of soil erosion is the increasingly serious destruction of soil surface vegetation. This results in loose soils, especially in the northern zone. ”

"Perennial irrational farming, indiscriminate logging, and mining have made the land not well-cultivated, and there are not enough plants to consolidate the land, and the soil quality is getting worse and worse."

"If we want to solve this phenomenon and prevent harm, the most important thing is the protection of vegetation."

"But you may not be able to imagine how serious the use and destruction of vegetation in Datang is. First, there was overgrazing in the border near the Turkic zone, and then there was irrational use and unreasonable cultivation in the territory of the Tang Dynasty. Deforestation and burning of mountains, daily use of firewood, inadvertent destruction in war. There is also a large amount of wood burned when the ancient technology of the salt works is used to boil salt, iron ore and other iron ores. As well as the shipbuilding industry and palace construction, a large number of wood raw materials are used. ”

"These are the causes of vegetation destruction, soil erosion, and flooding."

Everyone looked demented, Lao Cheng smashed his mouth, and said in surprise: "Good guy, so many reasons? Then how to govern it, don't say that you are a little half-immortal, even if the real immortal comes, there is no way! ”

Baili Yun spread his hands: "That's why I said that this is not something I can do alone, even if I get the support of His Majesty and even the entire Tang Dynasty, it can only be said that the occurrence of disasters has been suppressed and reduced to a certain extent." ”

Li Shimin's fingers trembled a little, and he said in a trembling voice: "That Qingyang, you can tell me the way!" ”

Baili Yun said: "Then let's talk about it one by one!" First of all, deforestation and burning of mountains, irrational cultivation and overgrazing must be restricted by His Majesty's order. ”

Li Shimin immediately said: "Keming, you also write, and write all the measures to draw up a charter and hand it over to me in a while." Ordered all prefectures and counties to strictly prohibit the destruction of forests and burning mountains, and those who violated the order confiscated all their family property and exiled to Lingnan. In addition, the reasonable methods of grazing and cultivation were laid down, and the peasants were taught, and after two years, those who disagreed with the regulations were fined 300 yuan. ”

Bailiyun watched coldly, and said in his heart, it seems that Li Shimin is still very courageous, he made a decision so quickly, he was decisive in killing, and he had the means!

Du Ruhui immediately took the pen and sat next to Fang Xuanling, and also took the pen and began to write quickly. Bailiyun saw Li Shimin signaling to continue, and said: "The second is the extensive use of salt and mining industries, which will use another thing, that is, coal, that is, black charcoal. This thing must also be known to you, it can also be burned, and now there are many places where it has been used in a large area, but the refining technology is too poor to be used completely, and the effect is slightly worse. I will inform Your Majesty of the extraction technology, and then hope that Your Majesty will return the Blackstone Carbon Ore to the imperial court, and hand over the refined coal to me for processing and sale, and I will turn it into a more suitable incendiary product to replace the use of firewood. ”

Li Shimin thought for a while, and then nodded: "Okay, anyway, only Qingyang you have the technology, and it's the same for anyone." In fact, now Li Shimin can only do this, after all, only Bailiyun can provide everything he needs, and they themselves are too unfamiliar with these things to start with. Compared with solving the problem, Bailiyun's use of public to make money for private purposes is not a matter, and it will pass with one eye and one eye closed. Moreover, if it is really concentrated in the hands of Bailiyun and sold in a unified manner, it will also be convenient for Li Shimin's centralized rule.

Bailiyun is very satisfied with Li Shimin's approach, this is the best way, just a win-win situation, each takes what he needs. And it seems that I will be able to get more convenience in a while.

Bai Liyun was happy in his heart, and his speech was no longer so blunt: "In addition, wood is used in the shipbuilding industry and the construction industry. The ship industry can use iron instead of wood, which is achievable, and we have made it overseas. But because I don't know much about this aspect personally, and I still need to do a lot of research, it may be a few years before it is actually implemented. ”

Everyone didn't doubt Bailiyun's words, even if he was talking about an iron boat floating on the river, which was an unlikely thing in the eyes of normal people. Because compared to what Bailiyun is showing now, they have become a little blind, even if Bailiyun tells them that people can fly like birds, they will probably not be too surprised.

Bai Liyun waited for Fang Du and the others to write for a while, and then continued: "As for the construction industry, I also ask Your Majesty to minimize large-scale construction projects. Give me a few months and I'll provide you with alternative wood materials, which will be provided to you directly by my building materials shop. And I will make a design plan to further use these materials to pave the streets of important towns such as Chang'an, which are smooth streets that are as hard as stones. ”

Bailiyun looked at Li Shimin with a smile and said, "Presumably, this will bring a lot of convenience to daily travel and information transmission." And the subjects will surely praise you for supporting this plan, Your Majesty for this project! ”

Li Shimin imagined it for a moment, a smile appeared on his originally decadent face, and he glanced deeply at Bailiyun.

Bailiyun knew that this was his proposal, and he thought about it, at the lowest time, especially when his reputation was about to plummet, there was a sudden rise in prestige and within reach, and who would refuse?

Li Shimin said with a smile: "Yes, this matter is very good, I will fully support it, I hope Qingyang can give me a satisfactory answer, I look forward to it!" ”

Bailiyun arched his hand and said: "The minister will do his best, and he will not dare to live up to His Majesty's expectations!" ”

Li Shimin is very satisfied with Bailiyun's attitude, although it is not hard-working, it is somewhat utilitarian. But being able to do good things, having the ability, and not rebelling means that Bailiyun is still a good subordinate.

Bai Liyun continued: "It's a more serious problem, just now we talked about deforestation and burning mountains. Why is the deforestation and burning of mountains? Because it is mainly displaced people who destroy forests and burn mountains, they have no money to buy land, or the land is occupied by big landlords and families, and there is no land to cultivate, so they have to destroy forests and burn mountains to open up new fields. ”

Chen Yanjin asked, "Then what should I do?" You can't let them starve to death, can you? ”

Bailiyun explained: "They destroy forests and burn mountains to open up new fields, in the final analysis, because there is no way out, because there is no source of livelihood, because they want to live. In that case, then we provide them with a way out where they can support themselves, so that they have a source of livelihood and can continue to live and support themselves. ”
