Xintan is a lake located in the southeast of Ziwei City. The Luoshui River divides into three streams in the Tianjin Bridge area, merges again to the south of Zuoyemen of the Imperial City, and then flows northeast to Huixunfang where it branches into a branch, namely Caoqu. Caoqu.
The canal has a gate. Once the gate is opened, the river flows into Xintan, then flows eastward and leads directly to the outside of the city.
Xintan is very important to Luoyang. It is not only an artificial lake, but also a huge dock.
During the Dazu period, merchants traveling to and from Beishi mostly parked here to load and unload supplies, so business travel flourished. It was the largest inland river port in the country. It is said that at its peak, tens of thousands of ships came and went in and out of the port a day.
"Your Highness, the Cao Canal flows from the northeast to the south of Lidefang, and overflows into a pond in the west. In Chang'an, Sinong Qing Zong Jinqing chartered a voyage from Tongzhou, and planted willows on all sides, making it a grand sight." On the cruise ship, Li Yanling said softly: "
There is a Xiecheng Canal in the north of Xintan that leads directly to Hanjiacang City. During the Xuanzong Dynasty, all the tenants east of Luoyang were kept here."
Hanjiacang City was very large, with a maximum grain storage of 5.83 million dendrobium, accounting for almost half of the national official grain reserves at that time, which shows its importance.
These grains from Henan, Hebei, Huainan, Jiangnan and other places were transported from outside the city through the canal, parked in Xintan, and then went north through the Xiecheng Canal to Hanjiacang City for storage.
If private grain storage is included, the grain in Luoyang can be enough to feed millions of people for a year.
Shao Shude laughed when he heard this and said, "Lao Li has read a lot of books recently."
Li Yanling also laughed: "I can't fight in battle, so I can only take care of these common affairs for your highness. The repair progress of Hanjiacang City is slow. If your highness wants to use it, please allocate more manpower. If you can store millions
With dendrobium grains, it is also more convenient to use troops."
Shao Shude sighed after hearing this.
Any capital city is a big consumer.
After all the repairs in Hanjiacang City are completed, six million grains can be stored, which is obviously not possible in Henan Prefecture alone.
Grains from Ziqing, Yun, and Yan were transported to Luokou through Jishui or the Yellow River, and then transported to Luoyang City through the Luoshui and canal systems.
Grains from Bian, Hua, Xu and other places were transported to Biankou through the Bianshui Channel, and then transported to Luoyang.
Grain from Hebei is transported to Luoyang through the Yongji Canal water system.
Luoyang in the imperial dynasty was mainly fed by Henan and Hebei, and its appetite was amazing.
In fact, from a shipping perspective, Bianzhou seems to be more suitable as a distribution center. After the difficulties, Luoyang was destroyed by the war, and the imperial court simply gave up on Luoyang and invested heavily in Bianzhou to build it into a shipping center and logistics center, making it a rapid development.
The largest metropolis in Kanto.
The prosperity of Bianzhou has lasted for more than a hundred years. If Shao Shude abandoned Luoyang, expanded Bianzhou and made it the capital, it seemed to be more cost-effective from an economic point of view.
But some accounts are not settled that way. After so many years of fierce fighting with Zhu Quanzhong, I know how difficult it is to fight around Luoyang. If there is no army to leave Xiangyang and Nanyang's surprise move to open up a second battlefield, Zhu Quanzhong will not be so easy.
Defeated.
Luoyang has dangerous mountains and rivers.
He never believed in the saying that the country was in danger but not in virtue. Zhu Quanzhong used native Tuan villagers to guard the dangerous terrain and continued to consume his elite Kansai soldiers. Is this exchange a huge profit? The lesson of being beheaded in the Northern Song Dynasty should be taken as a lesson.
.
Of course, some people will say that they have been beaten to the vicinity of Luoyang, and it is useless no matter how dangerous the terrain is, because the soldiers are no longer strong and will probably disperse in a hurry. But if you can have an extra advantage, why not?
Furthermore, since he started his career in Kansai, Luoyang is more suitable to influence the northwest than Bianzhou.
"Hanjiacang City is not in a hurry. It can now store 700,000 to 800,000 grains, which is about the same. There are still few registered households in Luoyang, so there is no rush." Shao Shude said, "However, many prisoners were sent from various places yesterday. I called
I will give you part of my manpower. When the water dries up in winter, the canals will be further dredged."
The Cao Canal runs parallel to the Luoshui River, heading east out of the city, and then merges into the Luoshui River in Yanshi County.
The Cao Canal is an artificial waterway, and part of its water source comes from the water cut off by it, and part of it comes from rainwater discharged from the Xiecheng Canal. If the water level is too low, the sluice on the Xintan side will be opened, and the Luo River will replenish it.
Ensure smooth shipping.
"As ordered." Li Yanling responded.
In fact, this matter is not entirely under the control of Li Yanling, and Shao Shude did not say this to him. Secretary Supervisor Lu Siye was already drafting documents, and the matter will ultimately be implemented by the Capital Water Supervisor and the Ministry of Works.
"If there is a flood, is there any plan to deal with it?" Shao Shude suddenly asked.
In the autumn of the fourteenth year of Kaiyuan, the water surged into the canal, flooding hundreds of chartered boats from various states, and many people drowned.
On the Shangyang Palace side, when Luoshui flooded several times, many places were flooded, so Xuanzong had to build additional dams.
"Your Highness, the Qianjin Pond in the west of the city, the Autumn Pond in Shangyang Palace, and the Jiuzhou Pond in Ziwei City have been dredged, or most of them have been cleared. The storage capacity has been greatly increased, and it will not be a problem." Li Yanling said.
To the west of the city is mainly the Luoshui River, and the Gushui River flows into the city. There are three lakes and reservoirs, which can indeed adjust the flood peak.
Xintan is mainly used to regulate the water flow and the water discharged from the Xiecheng channel under continuous heavy rains.
The final flow direction of this water is through the city and flows northeast into Luoshui River.
"I've seen Qianjin Pond, and it's really big, not bad. Jiuzhou Pond and Qiu Pond are a bit small, and after dredging, the storage capacity is still not enough. I'll ask Zhao Keyu, the capital water supervisor, to come see me tomorrow. I'm worried that there will be less rain in the future, and the canals will
, the water in the transport canal is shallow, which affects shipping." Shao Shude said.
There are four reservoirs in total, including Qianjin Pond, Qiuchi Pond, Jiuzhou Pond, and Xintan Pond. The last three are in the city, and their storage capacity is still much less than that of Qianjin Pond.
In fact, there is also Xiawangchi (Weiwangchi), but it is just a scenic spot, not a reservoir, it is a bit small.
Since they were all in Luoyang, Shao Shude had to worry about shipping.
The cold weather period is coming soon, and after the precipitation decreases, once water transportation is stopped, land transportation will have to be carried out, and the cost will increase. According to the data reported by Sinong Temple, a carriage can only load fifteen dollars on a post road with poor road conditions.
Dendrobium grain (about 0.8 tons), on a post road with good road conditions, more than 30 dendrobium grain can be transported. If it is a newly built first-class national highway, more than 40 dendrobium grain can be transported.
But if you use the canal, a ship can transport 1,500 grains, which is dozens or even a hundred times that of a horse-drawn carriage, and the cost is much lower.
Luoyang cannot bear the hyperinflation caused by the suspension of water transportation.
Alas, everyone has the urge to move the capital to the sea. Anyway, the barbarians of this era cannot attack from the sea.
"Your Highness, will the rain really decrease? The Imperial College sent people to monitor the Gushui, Zhanshui, Luoshui, and Yishui rivers. It rains constantly and the river water does not decrease." Li Yanling hesitated for a moment and asked.
"Be prepared for a rainy day, do you understand?" Shao Shude glared at him and said: "Pichi is the lifeblood of Luoyang, so we can't be careless. That's all. Tomorrow I will ask Zhao Keyu to go to Luhun County and choose a place to build a reservoir in the upper reaches of Yishui River.
, to prepare for unexpected needs. The canals are guaranteed, and there are still transportation canals."
The Yun Canal leaves the city from the southeast corner of Luoyang and merges into the Luoshui River. This is also an important shipping channel. The cargo transportation in Yinnan City relies entirely on this artificial river. The Yishui River merges into the Luoshui River in the east of Luoyang City. Once the water level drops,
The transportation canal will be affected, and this must be considered.
Therefore, it seems necessary to build a reservoir on the upper reaches of Yishui River.
While the two were talking, the cruise ship had sailed into Xintan.
****
"Here we come!" The boatman Song Erlang threw the hemp rope ashore, and Wang San caught it and tied it to the stone pillar.
The ship had docked. Workers on the shore rushed aboard and unloaded bags of grain.
Song Er and Wang San are also old acquaintances. They were drafted as boatmen many years ago to transport grain and grass for the Liang army in Rushui.
Song Er's son was still in Xie Yanzhang's army at that time. Fortunately, he came back alive and is now a member of the Ruzhou Prefecture Army.
Song Er and Wang San had already arrived in Luoyang.
As skilled boatmen, they were recruited by Henan Prefecture early to ensure Luoyang's material supply, and they worked there for two years.
"Luoyang's popularity is getting more and more popular." Song Er said with emotion as he looked up at the cities around Xintan where construction was going on.
"You have only been away for a few days, and you are so moved when you see the sky. Isn't Luoyang still the same Luoyang?" Wang San sneered.
"You don't understand." Song Er shook his head and said, "This time I went to Yique and found that it was very busy there. Almost all the people mobilized and went south."
"Where to go south?" Wang San asked.
"Do you know about the first-class national highway built by your Majesty?" Song Er asked after getting off the boat.
"Nature knows."
"The Yique section of Luoyang has been opened, the Yique and Linru sections have been opened, and just this month, the Linru and Liangxian sections have also been opened. Han Shijun of Ruzhou mobilized people to go south, and people from Yique and other counties in Henan Prefecture also went
, working together with Tangzhou and Dengzhou to build a first-class national road from Jiacheng to Fangcheng, a total of more than 200 miles." Song Er said: "Once this road is opened, we may have to return to Ruzhou in the future."
Wang San opened his mouth wide and stopped talking.
He wasn't sure whether this was a good thing or a bad thing. Returning to his hometown seemed good, after all, his family was still there. But living in Luoyang might not be a bad thing either. It was really hard to make a choice.
"The king of Xia either built roads or dug rivers. Even if the people in various places did not go to battle, they would die of exhaustion on the river banks. I thought it was mainly the people of Henan Prefecture and the people of Ruzhou who were tired. Now it seems that the people of Tang and Deng were not much better."
Wang San muttered.
"Hey, where are you? Duke Zhe ordered 20,000 Huai soldiers to descend to dig for water. That's cruel. People die of exhaustion every day." Song Er sneered, as if he didn't feel sorry for those Huai soldiers at all.
Bishui is the Tang River, connecting Fangcheng County at the southern end of the Wanye Corridor in the north and Xiangyang in the south.
Materials from Nanyang and Xiangyang were transported by water to Fangcheng County in Tangzhou, and then transported by road to Jiacheng County in Ruzhou, and then transferred to water transport. After arriving in Linru County, they then traveled overland for a while to Yique County, and were finally transported by water through Yixian.
To Luoyang.
The whole journey is more than 800 miles, 70% of which is waterway and 30% is dry road, transporting materials from Nanyang and Jianghan to Luoyang.
So you can understand why Shao Shude is so obsessed with the first-class national highway that connects the north and the south.
The 95-mile first-class national highway from Taihang Xingkou to Mengzhou has long been opened to traffic, and the 30-mile first-class national highway from Heyang Nancheng to Luoyang has also been opened this year.
In the south, the section from Luoyang to Linru was opened this year after more than two years of construction.
The focus now is to open up the 200-mile stretch of the Wanye Corridor. Once completed, Luoyang's hinterland will be significantly extended southward.
Shao Shude once had the idea to see if there was a possibility of a "cross-ridge canal" by building a ship lock, but in the end he gave up because it was unrealistic.
Later, an attempt was made to divert the Yi River into the Ru River, that is, to connect the Yishui River and the Ru River, but this was also abandoned.
However, Shao Shude has not given up yet. This time he sent Zhao Keyu to Luhun County to select a site for the reservoir. After the matter is completed, he will also inspect the surrounding geography to see if there is a way to connect the Yishui River and the Ru River.
Completely connecting all water systems is part of his long-term plan. Manpower is not a problem, what is lacking is technology, such as ship lifts.
