Pi Rixiu, a poet in the Tang Dynasty, said: "When the Tao is exhausted, it will be a river, and it will take a thousand miles." According to the materials, what is the influence of the Grand Canal?

Digging the Grand Canal was the need of political and economic development at that time. First of all, the political center of the Sui Dynasty was in the north, and most of the grain was supplied by the Jianghuai area. Relying on land transportation, the traffic flow is small, the speed is slow and the cost is high, which can not meet the needs. Most of China's major rivers are east-west, so it is imperative to open the North-South Canal and use hydraulic transportation. Secondly, the control of Jiangnan should be strengthened after the Sui Dynasty destroyed Chen. The main purpose of opening the Grand Canal in Yang Di is to "strengthen the north-south traffic and consolidate the rule of the Sui Dynasty over the whole country". There is no denying that Yang Di's desire to visit Jiangnan by dragon boat is also one of the motives for digging the canal. The rule of Emperor Wendi of Sui Dynasty for more than 20 years made the economic strength of Sui Dynasty increase rapidly, which provided sufficient material conditions for Yang Di to open the Grand Canal. The Grand Canal in Sui Dynasty, like the Great Wall, was one of the most magnificent projects in the ancient world. The opening of the Grand Canal has become the main artery of north-south traffic, which has promoted economic exchanges between the north and the south and consolidated the situation of national reunification.

The Sui Canal, with Luoyang as the center, starts from Zhuo Jun in the north and reaches Yuhang in the south, with a total length of more than 2,000 kilometers. It is divided into four sections: Yongji Canal, Tongji Canal, Shanyangdu (Hangou) and Jiangnan. It is one of the most magnificent projects in the world, connecting five major water systems: Yellow River, Yangtze River, Haihe River, Huaihe River and Qiantang River. The length of the canal is second to none in the world, and the depth, width and navigation capacity of the river are the largest. The canal was opened, and "business trips are coming and going, and ships are endless." Tang Piri Xiu said, "It is beneficial and rich for fishermen in Zhuo Jun County in the north to move to Jiangdu in the south!" (Pi Wen Zi's Argument on Heming). "Looking back on the past by the Bian River" (Pi Rixiu) says: "The Sui Dynasty lost me thousands of miles." Like the Great Wall, the Grand Canal enjoys a high reputation in the world, which embodies the intelligence and creativity of the working people in ancient China. The opening of the canal promoted the development of the city, and Jiangdu, Yuhang and Zhuojun flourished rapidly. It has safeguarded national unity and promoted centralization and stability.

The Beijing-Hangzhou Grand Canal is a great project created by the working people in ancient China, a precious material and spiritual wealth left by our ancestors, and an important living and flowing human heritage. The Grand Canal originated in the Spring and Autumn Period, formed in the Sui Dynasty and developed in the Tang and Song Dynasties. The Beijing-Hangzhou Grand Canal was built in the Spring and Autumn Period more than 2,000 years ago, with a history of 2,500 years. An important river channel dug by Qin Shihuang (Ying Zheng) in Jiaxing also laid the foundation for the development of Jiangnan Canal in the future. According to Yue Jue Shu, Qin Shihuang "ruled Lingshui Road from Jiaxing, crossed Qiantang River and crossed Zhejiang". About 2,500 years ago, Fu Cha, the king of Wu, dug a ditch, opened a canal connecting the Yangtze River and Huaihe River, and built Seoul, from which the canal and its culture were derived.

The Grand Canal we are talking about today was dug in the Spring and Autumn Period, completed in the Sui Dynasty, flourished in the Tang and Song Dynasties, straightened in the Yuan Dynasty, and dredged in the Ming and Qing Dynasties (dug in 486 BC and opened to traffic in A.D. 1293), which lasted 1779. In the long years, it has experienced three major construction processes. In the Sui Dynasty, Emperor Yang Di used more than two million people to dig the Grand Canal, which made great contributions to the unprecedented prosperity of the country's economy and culture. After the development of Tang and Song Dynasties, it finally became a traffic artery connecting Haihe River, Yellow River, Huaihe River, Yangtze River and Qiantang River in Yuan Dynasty.

The Grand Canal is the second "golden waterway" in China after the Yangtze River. Its value is comparable to that of the Great Wall, and it is the earliest and longest artificial river course in the world, which is 16 times that of Suez Canal and 33 times that of Panama Canal.

The Beijing-Hangzhou Canal has always been the main canal for water transportation in past dynasties, and played an important role in the economic and cultural exchanges between the North and the South. /kloc-shipping rose in the 0/9th century. With the opening of the Jin-Pu Railway, the role of the Beijing-Hangzhou Canal gradually decreased. After the migration of the Yellow River, the water resources in the reach of Shandong Province were in short supply, and the siltation was shallow, and the north-south navigation was cut off and silted up to the ground. The section of Jiangsu with large water volume and good navigation conditions can only sail in Xiao Mu. The abandonment and depression of the Beijing-Hangzhou Canal is a portrayal of the semi-colonial and semi-feudal system in China. After liberation, some river sections were widened and deepened, many modern docks and shiplocks were built, and shipping conditions were improved. Seasonal navigation mileage reaches 1 100 km or more. 660 kilometers south of Pixian County, Jiangsu Province, the 500-ton fleet can be unimpeded. The ancient Beijing-Hangzhou Canal will become a water conveyance channel for the future South-to-North Water Transfer Project.
