NO.1 Prosperity
The chasm was an early Chinese canal, excavated in the Western Zhou or Spring and Autumn Period, and the chessboard of the Chu River and the Han Dynasty
As the Central Plains, Henan started water transport very early, and the gap between the Spring and Autumn And warring states successfully connected the Yellow River and the Huai River, and the Henan waterway network was initially formed. Later, the Yellow River flooded, the chasm was silted up, and the ditch gradually replaced the chasm.
Drainage
The sand content of the Yellow River is extremely high, and the Canal has been dredged for a long time in the Eastern Han Dynasty and the Northern Wei Dynasty.
Sui and Tang Dynasty Grand Canal
Then there was the famous Sui and Tang Dynasty Grand Canal, and Henan shipping entered a brilliant era. Luoyang became a national shipping center and a world port, and large ships were two stories high.
Northern Song Dynasty Henan shipping
The Northern Song Dynasty was the pinnacle of shipping in Henan, with a nationwide shipping network centered on Kaifeng in Tokyo.
NO.2 Decline and navigation efforts on the Yellow River
Huashi gang played for twenty years
During the Northern Song Dynasty, there were many boats, and the river was very badly blocked. The flower stone class aggravated the congestion of the river, seriously affecting the transportation of grain from the south to the north, as well as the deployment of anti-gold.
The sediment content of the Yellow River is too high, which seriously affects the smooth flow of the river
The main problem of the Henan Canal is the Yellow River, which changes the course of the river many times, the uncertainty of the water flow and the bottom of the river is very high, and the high sediment content has led to the maintenance of the dynasties unless they are not used. The taiping year is relatively easy to say, and it is easy to take care of it when a war starts.
After the Southern Song Dynasty, the Sui-Tang Grand Canal withdrew from the mainstream of China's canals, and the Beijing-Hangzhou Grand Canal replaced it.
Sanmenxia
Here to talk about the Yellow River shipping, in fact, the three dynasties of the Yuan, Ming, and Qing dynasties all wanted to break through the Yellow River shipping problem. The Yuan Dynasty envisioned the excavation of the Sanmenxia Channel, which could not be calculated, so it was calculated. The Ming Dynasty really did it, restored the Sanmenxia Channel, and worked hard until the Kangxi period of the Qing Dynasty, but the effect was still limited, so it gradually gave up.
In modern times, the Yellow River flooded several times, the railway began to flourish, and in 1938, the Garden Mouth broke the embankment, and Henan shipping completely fell into the valley bottom.
NO.3 Re-departure
After the founding of New China, the construction of water conservancy was an issue to which the state has always attached importance. In the 1950s, the Shaying River and the Jialu River were dredged to varying degrees, and the Wei River and Danjiang River eliminated obstacles and obstacles, restored the shipping function of the Huiji River, and excavated a number of tributary canals.
In the 1960s, the floods in Henan were very serious, and at that time, the flood resistance was the first in that situation, and the waterway naturally gave way
In the 1960s, Henan's flood resistance was very severe, because of the flood and other factors, the shaying river damming seriously affected the eastward navigation route, the Weihe river built some low bridges, in order to resist the flood, the importance of water conservancy is higher than shipping, so Henan's waterway impact is relatively large. Since the late 1970s, Henan has continued to improve its inland navigation capacity, but it is still subject to objective conditions such as floods and dry water.
In 2021, 359 major water conservancy projects in Henan Province began construction
The premise of inland river shipping is water conservancy, and with the further strengthening of Henan's water conservancy construction, including the introduction of the river to Jihuai, the great development of shipping will come to fruition.
Henan's water transport system is dominated by the Huai River Basin, supplemented by the Yangtze River Basin. After years of hard work, history has taught us that it is now necessary to keep the Yellow River out of the canal system because the sediment content of the Yellow River is too high. Even though the flooding of the Yellow River is relatively controllable today, the sediment content will lead to a series of problems such as river siltation.
With the continuous breakthrough in the treatment of the Yellow River, the annual sediment content of the Yellow River has decreased sharply
As progress continues to be made in the upstream control of soil erosion, the Yellow River, if it is getting clearer, is a good potential channel, and it will take time.
During the 13th Five-Year Plan period, Henan water transport has made great progress, and the 14th Five-Year Plan is currently being prepared. With the continuous progress of water conservancy construction and the improvement of the ability of the high-grade waterway network in the neighboring province of Suwan, Henan's shipping development has ushered in good development opportunities, and Henan shipping through the river to the sea will once again go to glory.
Henan has a huge team of sailors, 5,000 Henan ships traveling the Yangtze River, which is traditional
