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 was under great pressure in Nanyang, and it was not just a problem for Majapahit. It seemed that many Hui countries had united. Because the Shi family's arbitrary trade with the Ming Dynasty had been transformed into military and military affairs due to commercial issues. It's a political issue.

Fortunately, the Ming Dynasty won a great victory in Luchuan and won a beautiful victory.

Suppressing the imminent moves of various countries in Southeast Asia.

Therefore, the Shi family really wanted to get support from Daming.

Wang Zhen said: "I have promised on behalf of the emperor to give him some artillery guns and gunpowder to trade in Tianjin. I just think that the Shi family may not welcome the establishment of Nanyang Guard."

Zhu Qizhen said: "Let's put it down now. I don't care about Nanyang. Where is Mr. Yu?"

Wang Zhen said: "The following people came to report that Mr. Yu has arrived from Shunde Mansion and will arrive in the capital within a day or two."

Zhu Qizhen said: "It's just like Mr."

Facts have proved that Yu Qian arrived very quickly.

It arrived on the second day.

Zhu Qizhen met Yu Qian after his morning visit.

In the Qianqing Palace, Zhu Qizhen saw Yu Qian and immediately said: "Sir, you have lost weight."

Yu Qian's hard work is directly reflected on him. At this moment, Yu Qian is a bit skinny and has a strong-willed look. It seems that he has a mutual understanding.

It's just that I don't know how much more haggard than before.

Yu Qian said: "Your Majesty has given you too much praise. I believe that water control in Hebei Province cannot be delayed without delay."

Zhu Qizhen said: "Sir, do you have any strategies?"

Yu Qian pondered and said, "Yes, I brought a map, which is outside the palace."

There are certain rules for meeting the emperor. At least Yu Qian cannot bring large items into the palace.

Zhu Qizhen immediately said to Wang Zhen: "Wang Daman, pass quickly."

Wang Zhen agreed and immediately held up a roll of white cloth as tall as a person.

Then the two eunuchs pulled away from each other.

The mountains and rivers of Zhili are vividly displayed on the paper, but they were drawn by Yu Qian stroke by stroke. The countless complete rivers are clearly depicted.

Zhu Qizhen walked a few steps and immediately smelled a smell of sweat. He also found that the silk cloth was a little yellow, as if it had been soaked through by sweat. When he looked carefully at the texture on it, he saw that this large map had a patch. Pieces of cloth one foot square are sewn together.

It's just that the stitching is so fine that you can see it clearly from a distance, but you can only see it when you get closer.

In Zhu Qizhen's mind, he seemed to see Yu Qian in the dim candlelight for countless nights. Yu Qian concentrated on drawing what he saw during the day on the map, and then carried him close to his body, so that he was completely covered with sweat. The silk cloth got wet, so it turned yellow all over.

Then Zhu Qizhen took a closer look at the river course on the map.

When Yu Qian saw Zhu Qizhen looking at the map carefully, he immediately took a few steps forward and said, "I traveled all over Hebei to survey the rivers. The key to water control in Hebei lies in the five rivers and three lakes."

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

"The three lakes are Triangle Lake, Baiyang Lake and Dalu Lake."

Then 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 put a lot of effort into it, there is still no way to compare this map with the places in later generations. However, it also clearly marked all the major rivers that finally converged in Tianjin.

From north to south, there are the Chaobai River and Beiyun River water systems, the Lugou River water system, the Daqing River water system, the Ziya River water system, the South Canal water system, and the Zhanghe and Weihe River systems.

In addition to these five major river systems, there are three lakes that are particularly clearly marked on the map: Triangle Lake, Baiyang Lake, and Dalu Lake.

Yu Qian explained everything to Zhu Qizhen one by one.

In fact, there is no need to explain much. The Chaobai River is connected to the North Canal east of the capital and can be understood as the water source of the North Canal, not to mention the Marco Polo River.

As for the Daqing River, the section from Baiyangdian to Sanjiaodian is called the Daqing River, but the Daqing River itself is divided into two major tributary systems.

Ziya River is south of Daqing River.

The Hutuo River is in the Daqing River system and sways back and forth with the Ziya River system. It flows from the mainland to the South Canal and flows into the South Canal. The overall terrain of Hebei has the Yanshan Mountains in the north and the Taihang Mountains in the west. There is a huge height difference, and a lot of rainfall

Collect them together and gather them in Tianjin.

As for the largest of the Three Lakes Triangle Lake, it is hundreds of miles wide to the west of Tianjin. Baiyang Lake is west of the Triangle Lake and is connected by the Daqing River. Sometimes when heavy rains continue, it stretches for hundreds of miles from the south of the capital.

It stretched endlessly, houses were destroyed, and fertile fields were submerged.

Triangle Lake and Baiyang Lake are connected into one.

As for Dalu Ze, Cao Nai introduced it before, but now he will not explain it one by one.

Zhu Qizhen listened carefully, sighed in his heart, and said to himself: "What a big problem."

In fact, there are more than five tributaries of rivers flowing down from Taihang Mountain and Yanshan Mountain. There is an old saying that nine rivers flow down to Tianjin. Jiuhe does not mean that there are nine rivers, but nine is the number of poles.

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

In fact, these rivers are not fixed.

It would be much simpler if these river channels were fixed. Because these river channels migrate irregularly and there are no fixed rules at all.

After Zhu Qizhen read it, he said to Qian: "Sir, you must have something to teach me."

Yu Qian said: "I believe that the general policy of Zhili river management should be to block the upper part, store it in the middle and divide it at the lower part."

Yu Qian waved his hand, rowed across the west of Zhili, and said: "The biggest problem in mountain tourism is that flash floods break out in summer and autumn, and they are like thunder. The rivers cannot bear it."

"That's why we often broke up with each other and even changed our paths."

"Therefore, the biggest priority in the upper reaches is to separate the clear from the turbid, so that each river channel can find its place and protect the lives and property of the people."

"So the key lies in the word "stop"."

"Please use the Yongding River as an example, the strategy of condensing water to attack sand, and stimulate the water power to make it flow downwards."

Zhu Qizhen nodded and said: "In this way, floods can be prevented, but what about droughts?"

The climate in Hebei has always been better than floods.

From this point of view, how to utilize Hebei's water conservancy resources is more important than flood control.

Yu Qian said: "In my opinion, Baiyangdian, Sanjiangdian and Daluze should be used as the center to store floods and dig canals for water conservancy."

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

"Once the floodwaters enter the lake, the lake surface will surge and encroach on the flat land. Therefore, in my opinion, the three lakes should be renovated on a large scale, that is, lake embankments should be built around them to prevent the lake water from overflowing, and deep digging and dredging should be carried out during the dry season to allow the water to flow out.

Lakes can hold more water."

Zhu Qizhen felt something in his heart after hearing this, and thought to himself: "Isn't this using these three big lakes as three big reservoirs?"

He looked at the three big lakes again. It seemed that rivers could be seen with the naked eye, spreading out from the three big lakes.

If Yu Qian's plan succeeds, then most parts of Zhili Prefecture will be irrigated centered on the three large lakes.

Water is the best fertilizer for food.

As long as there is sufficient water, food can be produced even if the fertilizer cannot keep up. However, if there is no water, no matter how fertile the land is, it cannot produce food.

This plan alone made Zhu Qizhen very satisfied. Using lakes to regulate the river was simply an attempt to avoid reality and replace reality.

"It's just." Yu Qian hesitated and said, "If this happens, there will be a very big hidden danger."

Zhu Qizhen said: "Sir, please speak."

Yu Qian said: "The strategy of confining water to attack sand will rush a large amount of sediment into the three lakes. The lake level is gentle, and the sediment will settle in the lake. The lake in Hebei itself is not deep. The sediment accumulates day and night.

I’m afraid this lake will be filled up within a few years.”

After hearing this, Zhu Qizhen was moved in his heart. He thought to himself: "I have never heard of any big lakes in Hebei in later generations. Is this the reason?"

When the sediment of the Yellow River was in Jiangsu, it pushed the Jiangsu coastline an unknown distance. Later, when it entered the sea from Shandong, it pushed the Shandong coast an unknown distance.

Although the sediment accumulation in the upper reaches of the Hai River is not as severe as that of the Yellow River, although these lakes are large, they are definitely not seas. What will happen if this sediment accumulation occurs.

Zhu Qizhen can imagine it.

I just weighed the pros and cons and sighed, but there was nothing I could do.
