Chapter 49 General Policy of Three Lakes and Five Rivers

After Wang Zhen came over, he immediately reported to Zhu Qizhen.

Sure enough, the Shi family had a lot of pressure in Nanyang, not just the problem of Majapahit. It seems that many of the returning countries have united. Because the trade between the Shi family and the Ming Dynasty has been transformed into military and political problems because of commercial problems.

Fortunately, Daming won a big victory in Luchuan and fought a beautiful victory.

It has suppressed the impatience of the countries of the South Seas a lot.

So the Shi family really wanted to get the support of Daming.

Wang Zhen said: "The minister has promised to give him some artillery gunpowder on behalf of the emperor, and he will trade it in Tianjin." It's just that the minister thinks that the Shi family may not welcome the establishment of Nanyangwei. ”

Zhu Qizhen said: "Let's put it down in advance." Regardless of Nanyang, where is Mr. Yu? ”

Wang Zhen said: "The people below have come to report that Mr. Yu has arrived from Shunde Mansion, and he will arrive in Beijing within a day or two." ”

Zhu Qizhen said: "It's equal to Mr." ”

It turns out that Yu Qian came quite quickly.

The second day arrived.

After Zhu Qizhen was in the early dynasty, he met Yu Qian.

In the Qianqing Palace, Zhu Qizhen saw Yu Qian and immediately said, "Mr. is thin." ”

Yu Qian's hard work is directly reflected in him, and Yu Qian at this moment is a little skinny and iron-clad. It seems that there is a bit of a heart.

It's just that I'm more emaciated than before, I don't know how much.

Yu Qian said: "Your Majesty has a good reputation. The minister thought that Hebei's water control was urgent. ”

Zhu Qizhen said: "Does Mr. have a strategy? ”

Yu Qian pondered and said: "Yes, the minister brought a map, just outside the palace. ”

Audience with the emperor is a certain rule. At the very least, it was impossible for Yu Qian to bring large objects into the temple.

Zhu Qizhen immediately said to Wang Zhen: "Wang Daban pass quickly." ”

Wang Zhen agreed, and immediately picked up a roll of human-height white cloth.

Immediately, the two eunuchs pulled away from the left and right.

The mountains and rivers of Zhili jumped on the paper. But it was drawn by Yu Qian with one stroke. Countless rivers are depicted clearly.

Zhu Qizhen walked a few steps, and immediately smelled a smell of sweat, and also found that the silk cloth was a little yellow, as if it was soaked by sweat, and then looked at the texture on it, but saw that this large map, but there were pieces of cloth sewn together one foot square.

It's just that the stitches are fine, and you can see it clearly from a distance, and you can only see it when you get closer.

In Zhu Qizhen's mind, it seemed that he saw Yu Qian in countless nights, in the dim candlelight, Yu Qian concentrated on drawing everything he saw during the day on the map, and then carried him close to his body, so that the sweat completely wet the silk cloth, so that the whole was yellow.

Immediately, Zhu Qizhen took a closer look at the river on the map.

Yu Qian saw Zhu Qi

Zhen carefully looked at the map, and immediately took a few steps forward and said: "The minister has traveled all over Hebei, surveyed the rivers, and the key to water control in Hebei is in the five rivers and three lakes." ”

"These five rivers are Chaobai River, Lugou River, Daqing River, Ziya River, and South Canal."

"The three lakes are the Triangle Lake, the Baiyangdian Lake, and the Continental Lake."

Immediately, Yu Qian pointed out the locations of the five rivers and three lakes to Zhu Qizhen one by one.

To be honest, although Yu Qian has a lot of mental strength, there is still no way to compare this map with the places of later generations. However, it is also clearly marked that the last few major rivers in Tianjin are all marked.

From north to south, it is the water system of Chaobai River and North Canal, the water system of Lugou River, the water system of Daqing River, the water system of Ziya River, and the water system of South Canal, that is, the water system of Zhanghe River and Wei River.

In addition to these five major water systems, there are three lakes marked on the map, Triangle Lake, Baiyangdian Lake, and Continental Lake.

Yu Qian explained to Zhu Qizhen one by one.

In fact, there is no need to explain more, the Chaobai River is connected to the North Canal in the east of Jingshi, which can be understood as the water source of the North Canal, not to mention the Lugou River.

As for the Daqing River. It is the section from Baiyangdian to Triangle Lake that is called the Daqing River, but the Daqing River itself is divided into two major tributary water systems.

The Ziya River is south of the Daqing River.

The Hutuo River is in the Daqing River system, swaying back and forth with the Ziya River system. From the mainland to the outflow, it flows into the South Canal. The overall topography of Hebei, there are Yanshan Mountains in the north, Taihang Mountains in the west, the height difference is very large, and a large amount of rainfall is gathered down and gathered in Tianjin.

As for the largest of the Three Lakes Triangle, it is hundreds of miles west of Tianjin. Baiyangdian is in the west of the triangle lake again, connected by the Daqing River, sometimes when the heavy rain continues, from the south of Gyeonggi, stretches for hundreds of miles, the mighty and mighty, the endless horizon, the houses are washed away, and the fertile fields are submerged.

The triangle lake and Baiyangdian lake are also connected.

As for the mainland, Cao Nai introduced it before, and now I won't explain it one by one.

Zhu Qizhen listened carefully, sighed in his heart, and said secretly: "It's really a big problem. ”

In fact, from the Taihang Mountain, the Yanshan Mountain rushed down the river, not to mention the five major tributaries, there is an old saying, it is said that the nine rivers go down to Tianjin, and the nine rivers do not say that there are nine rivers, but nine are the poles.

During this period, Zhu Qizhen also conducted a detailed investigation of the water system in Hebei.

In fact, these rivers are not fixed.

If these rivers were fixed, it would be much simpler. Because these rivers are unstable. There are no rules at all.

After Zhu Qizhen read it, he said to Qian: "Mr. must have taught me." ”

Yu Qian said: "The minister thinks that the general policy of Zhili to govern the river should be to block up, store in the middle, and divide down. ”

Yu Qian waved his hand, crossed the west of Zhili, and said: "In the mountain tour, the biggest problem is the outbreak of flash floods in summer and autumn, which is like thunder. The river is unbearable. ”

"So repeatedly broken, even

Diversion. ”

"Therefore, the most important thing in the upper reaches is to clear the turbidity and separate the rivers so that they can be in their place. Protect the lives of the people. ”

"So the key is a stop."

"Please use the Yongding River as an example, the strategy of restraining water and attacking sand, and stimulate water power to make it profitable."

Zhu Qizhen nodded and said, "In this way, the flood can be prevented, but what about the drought?" ”

The climate of Hebei has always been better than drought than flooding.

In this regard, how to make use of Hebei's water resources is more important than flood control.

Yu Qian said: "In the opinion of the minister, we should take Baiyangdian, Triangle Lake, and Continental Ze as the center, store floodwaters, and dig canals for water conservancy. ”

"It's just that the terrain of Hebei is flat, and the water level of the three lakes is not too deep."

"As soon as the flood water enters the lake, the lake level rises and encroaches on the flat land, so in the opinion of the minister, the three lakes should be repaired on a large scale, that is, the perimeter of the lake should be built to prevent the lake from overflowing, and in the dry season, deep dredging should be carried out so that the lake can hold more water."

Zhu Qizhen's heart moved when he heard this, and he said secretly: "Isn't this taking these three big lakes as three big reservoirs?" ”

He looked at the three great lakes again, and it seemed that the canals were visible to the naked eye, spreading out from the three great lakes.

If Yu Qian's plan succeeds, most of Zhili Prefecture will be irrigated, with the three large lakes as the center.

Water is the best fertilizer for food.

As long as there is sufficient water, even if fertilizer cannot keep up, food will be produced, but without water, even fertile land will not be able to produce food.

This plan alone made Zhu Qizhen very satisfied, and he used the lake to control the river. It's just a move to avoid the real and make it virtual.

"Just." Yu Qian hesitated for a moment and said, "In this way, there is a very big hidden danger. ”

Zhu Qizhen said: "Sir, please speak." ”

Yu Qian said: "The strategy of harnessing water and attacking sand will wash a large amount of sediment into the three lakes, and the lake level is slow, and these sediments will be precipitated in the lakes, and the lakes in Hebei are not deep." Sediment accumulates day and night, and the lake may not be filled up in a matter of years. ”

Zhu Qizhen listened, and his heart moved. Secretly said: "In later generations, I haven't heard of any big lakes in Hebei, is this the reason?" ”

When the sediment of the Yellow River was in Jiangsu, it pushed out the coastline of Jiangsu I don't know how far, and later it was used to enter the sea from Shandong, and how far the coast of Shandong was pushed out first.

Although the sediment accumulation in the upper reaches of the Haihe River is not as strong as that of the Yellow River. But although these lakes are big, they are definitely not the sea, and what will happen to them under the accumulation of sediment.

Zhu Qizhen can imagine.

Just weigh the pros and cons and sigh lightly, but there is no way.

It's a good idea to let the river go straight to the sea unimpeded, but what about a big drought? There is a two-pronged approach to the world.
