Quanzhou, "eighty miles of water springs, take the spring flow is clear".

The city is in the downstream of the water and Gushui, the city wall is more than seven zhang wide (17 meters), divided into two cities inside and outside, all rammed earth version building. The outer city is three miles horizontally and vertically, and most of the city walls were destroyed by the flood, and now only the inner city of more than one mile is left horizontally and vertically, which is still intact. A gate was opened in the south wall. In the fourth year of the former Han Dynasty (119 BC), a salt official was set up in Quanzhou. This is one of the 38 counties that had salt officials at the time. If there were no floods, it would be a very prosperous city.

"The land is rented, and the salt and iron are profitable." There are orchards in the west of the thistle country, and there are fishing salts in the east. As long as the flood is controlled, why not worry about not being rich in the world.

It is different from the north-south Cao Canal built by Cao Mengde during his northern expedition to Wuhuan. Liu Bei wanted to build an east-west canal. From east to west, there are nine major rivers in the territory: Yishui, Luoshui, Hutuoshui, Juma Shui, Shengshui, Yushui, Gushui, Baoqiu Shui, and Xunshui (Gengshui), and Zhijin is a huge water system of countless people, which are connected into one.

Although the water network in the country is vertical and horizontal, the nine major rivers are divided into three places: east, middle and west. It's hard to get in touch with each other. According to the original plan, Liu Bei was to connect the nine major rivers, and put several Daze along the way, such as Kangze, Dulidian, Yongnuxu, etc., to regulate the water source. When the water is abundant, the remaining water can be injected into the water along the canal to prevent flooding. When the water is dry, the stored water of the serval is diverted to irrigate the farmland and continue to protect the waterway.

There are several natural reservoirs in the territory. The impact is huge. In later generations, wetlands that can play an important role in resisting floods, regulating runoff, purifying water pollution, and conserving water sources will be called the kidneys of the earth. That's why.

A swamp is a type of wetland. Wetlands are defined in subsequent conventions as: "Shall, irrespective of whether they are natural or artificial, permanent or temporary, marshlands, peatlands or areas of water, with bodies of water that are either static or flowing, or fresh, brackish or brackish, including waters not exceeding six metres in depth at low tide." ”

Therefore, wetlands in a broad sense include: rivers, lakes, swamps, coral reefs, etc. In addition, constructed wetlands such as reservoirs, fish (shrimp) ponds, salt ponds, and rice paddies are also included (please note).

Just as everyone regards the displaced people as a flood beast, Liu Bei regards them as strategic resources that continue to accumulate. From another point of view, Zesu is also very helpful. From west to east, a lake in the territory that is prescribed for several miles, tens of miles, hundreds of miles, or even thousands of miles is the kidney of the thistle country. Raise the people for the Tuntian of Jiguo and continue to make blood.

The so-called "water depth of no more than six meters at low tide" is replaced by the current expression: "shallow cannot be used by cars and horses, and deep cannot carry boats." ”

Look. Throughout the ages, the principle has been the same. It's just another way of saying it.

When Liu Bei arrived, Quanzhou Changbingyuan was busy building the outer city.

Bing Yuan confessed: "I wanted to build the city before the arrival of the lord and the king." However, the heavens did not fulfill people's wishes, and it has not been fulfilled so far. ”

"It doesn't matter." Liu Bei helped Bing Yuan up: "The talent of the Ming Court should be reused." The migrating official is here, and he is lonely and guilty. ”

"Quanzhou is also the land of the country of thistle. How can you let it wither and sit idly by? The minister is not good at words. I am willing to do my best for the king. "Goodbye Bingyuan.

Looking around at the sturdy outer city wall, Liu Bei couldn't help but smile and asked: "Quanzhou is located in the south of the confluence of water and gushui, and the north of the giant horse water and Hutuo water. If safety is safe, why did Ming Ting build the city first instead of the polder? ”

Bing Yuan was stunned: "The ministers all think that building a city is the first." ”

"Oh?" Liu Bei's eyes lit up: "I want to hear it in detail." ”

"The ministers and the other three, although they all moved to other places, they exchanged letters from time to time. You'an and Ziyu both thought that the six counties of Jiguo wanted to accept millions of people, and in addition to Linxiang, the remaining five counties should do their duty. Anci has been repeatedly invaded by the sea, and the soil is salted, which is not suitable for rice cultivation, but it is very suitable for growing alfalfa. And Quanzhou sits on the benefits of fishing and salt, and is connected to the river and the sea. It is the first choice of the port city. Therefore, first build a city and repair a port, and then do other things. Bing Yuan talked eloquently.

"Haha......" Liu Bei stroked his palms and laughed: "A dragon in Beihai, sure enough!" ”

"The lord praises falsely, and the ministers dare not be ashamed." Bingyuan bowed.

was peeped into by the three of them to determine the country's scheme, Liu Bei was not worried but happy. Then he happily asked: "Where does Quanzhou Port want to be built?" ”

"Lord, look." Bingyuan took a branch in his hand and drew it carefully on the ground. The surrounding mountains and rivers are all in the chest, which shows good intentions.

"Gushui goes out of the southeast outside the plug, and the water is combined in the west, and enters the sea in Quanzhou." First drawing the trend of a river, Bing Yuan said: "Baoqiu water is combined with the water in the east and the water (gēng) in the southeast, and enters the 'Xia Ze' in the southeast, and the south of Ze is more than ten miles in the wind, and the north is 'Pei Qianze', and the eyes are boundless." It is south to the north of Yongnu County, and Qu Dong enters the sea. ”

The two rivers are like two arms bends in the east and west, converging to form a thousand miles of Yongnu Xu. In other words, whether His Majesty will only include Yongnu County in the Ji Kingdom, or will the entire Qianli Yongnu Serval be assigned to the Ji Kingdom. If the Yongnu Servus are all in the country, the border of the country will be thousands of miles. Well, find a time to ask.

"Open the Quanzhou Canal under the city, connect the Baoqiu water in the southeast, and you can borrow Xia Ze and Peiqian Erze on it, and transfer the water (jū) to connect the Geng water and wet the water. It can pass through the east and west lakes of Li, and connect with Juma Water and Hutuo Water. Once the waterway is connected, then build a dike and canal, build a polder, and the water in the Yongnusu will flow into the sea from the east. ”

"Quanzhou Canal ......" Liu Bei's eyes cruised back and forth on this long canal from northeast to southwest, and he woke up: "This canal connects Xunshui, Baoqiu, Gushui, Yushui, Juma, and Wushui; After connecting the three cities of Yongnu, Quanzhou and Yichang, it enters Dongdian. Then through the channel dug by the former chief of the capital, it went south to Hutuo Shui, and then turned to Zhangshui, and entered the big river through Nanpi. ”

"Yes!"

The Quanzhou Canal is different from the Jiguo Canal. Jiguo Canal is through Fanyang, Fangcheng, Anci, Yongnu. It is a golden waterway that connects Yishui, Juma Water, Holy Water, Yushui and Gushui.

The two waterways can connect the nine major water systems in the territory.

Obviously, in terms of cost, the Quanzhou Canal is lower. However, in terms of coverage area and economic benefits, the Jiguo Canal, which is located in the middle, is stronger.

Because if you go to and from the six counties in the east and west through the Quanzhou Canal in the south, the cities in the north need to be detoured. Especially from the capital of Gyeonggi, Jiguo, it is too far away from the hometown. However, as far as water transport is concerned, the extra few hundred miles of waterway is only a day late.

However, the labor and construction costs of this Quanzhou canal are much lower than those of Jiguo Canal. An even greater advantage is that this canal can enter the Lěi water through the Gengshui and reach the Wuhuan Wangting Station in Youbeiping. You can also go out of the jam through the wet water to reach the White Sandalwood City, and the shore of the White Sea of the Vice-Fu Luo Clan's Standing High Car Royal Court. In the long run, the effect of the Quanzhou Canal may be greater.

"Why don't you dig the Quanzhou Canal first, and then build the Jiguo Canal." Liu Bei made up his mind.

The problem is that the two Daze, 'Xia Ze' and 'Pei Qianze', are both in the north of Yongnu. There is also "Yanfangdian" in the west. "Yanfangdian is hundreds of miles away, geese gather in spring, and there are many water chestnuts in summer and autumn."

In later generations, from west to east, the "Yanfangdian", "Xia Ze" and "Pei Qianze" were distributed in the shape of "Pin", which are all part of Yongnusu nowadays. Ethereal and boundless, the water and the sky are connected, which is the northern border of Yongnusu.

Like digging Lidian, Yongnu is shared by several surrounding counties, but not all belong to Yongnu County.

Anyway, it is still necessary to ask my majesty. Is it Yongnu Xue or Yongnu County......
