What are the functions of the canal? The role of the Grand Canal

A canal is an artificial waterway used to communicate water transport between regions or bodies of water, usually connected to natural waterways or other canals. In addition to shipping, canals can also be used for irrigation, flood distribution, drainage, water supply, etc.

China's canal construction has a long history, in 219 BC, in order to communicate the Xiangjiang River.

and the Li River between the shipping and the excavation of the Ling Canal, the Beijing-Hangzhou Canal.

It is the longest canal in the world.

The role of the Grand Canal connects the five major water systems of the Hai River, the Yellow River, the Huai River, the Yangtze River and the Qiantang River, bringing convenient transportation and promoting agricultural development and commercial prosperity. The Grand Canal is a great project on the eastern plain of China, a great water conservancy structure created by the ancient Chinese working people, the longest canal in the world, and the earliest and largest canal in the world.

The successful construction of the Grand Canal has allowed China's Grand Canal to serve as an important passage in the history of water transportation for more than 1,200 years. These Grand Canals have played an important role in China's history, and some of them are still in function today, such as the world-famous Beijing-Hangzhou Grand Canal.

The Grand Canal was founded in 486 B.C., and its history has lasted for more than 2,500 years. The Grand Canal includes the Sui-Tang Grand Canal, the Beijing-Hangzhou Grand Canal and the East Zhejiang Grand Canal, with a total length of 2,700 kilometers, spanning more than 10 latitudes on the earth, spanning Beijing, Tianjin, Hebei, Shandong, Henan, Anhui, Jiangsu, Zhejiang 8 provinces and municipalities directly under the central government, running through the Great Plain of North China, reaching the five major water systems of Haihe River, Yellow River, Huai River, Yangtze River and Qiantang River, and is the main artery of north-south transportation in ancient China.

In addition to shipping, the main function of the Grand Canal is that the canal can also be used for irrigation, flood distribution, drainage, water supply, etc.

China has a long history of canal construction, and the Xu River, which was dug in 506 B.C., is the world's oldest man-made canal, the earliest canal recorded in China, and the earliest canal in the world. In the twenty-eighth year of Qin Shi Huang (219 BC), the Ling Canal was dug to communicate shipping between the Xiang River and the Li River. The Beijing-Hangzhou Grand Canal, built mainly during the Sui Dynasty in China, is the longest canal in the world.

The opening of the Grand Canal has effectively promoted the economic and cultural exchanges and development between the north and the south, and has also played an important role in consolidating unification and promoting the development of coastal areas.

Later significance: Dynasties after the Sui and Tang dynasties transformed the Grand Canal so that it continued to play the role of a north-south waterway.

The Beijing-Hangzhou Grand Canal has played a huge role in the economic and cultural development and exchanges between the northern and southern regions of China, especially the development of the industrial and agricultural economy along the route. The Beijing-Hangzhou Grand Canal is also one of the oldest. Together with the Great Wall of China and the Karez of the Beijing-Hangzhou Grand Canal, it is known as the three major projects in ancient China and is famous all over the world.

The Beijing-Hangzhou Grand Canal is a great project created by the ancient Chinese working people, a precious material and spiritual wealth left to us by our ancestors, and an important human heritage that is alive and mobile. The Grand Canal began in the Spring and Autumn Period, formed in the Sui Dynasty, developed in the Tang and Song dynasties, and finally became a water transportation artery connecting the five major water systems of the Haihe River, the Yellow River, the Huai River, the Yangtze River and the Qiantang River in the Yuan Dynasty.

In the course of more than 2,000 years of history, the Grand Canal has been China's economic development and national unification.

First, social progress and cultural prosperity have made important contributions and are still playing a huge role today. The Beijing-Hangzhou Grand Canal shows the outstanding achievements of ancient China's water conservancy and shipping engineering technology leading the world, leaving a rich historical and cultural heritage, giving birth to a number of famous cities and ancient towns like bright pearls, accumulating profound and long-standing cultural heritage, and condensing a huge amount of information in China's political, economic, cultural and social fields. The Grand Canal and the Great Wall are both symbols of the cultural status and identity of the Chinese nation.

A canal is an artificially dug shipping channel used to communicate rivers, lakes, oceans and other waters, which can improve shipping conditions and shorten the time and distance of transportation.

China is the first country in the world to open a canal, as early as the Qin Dynasty more than 2,000 years ago, on the watershed between the Xiang River and the Li River, dug into a more than 30 kilometers long Ling Canal. It was the world's first lock-type canal. Because ships can "climb mountains and mountains" through locks, the canal is also known as a "bridge" to communicate with waterways.

The completion of the Ling Canal made the transportation between Hunan and Guangxi smooth at that time, and the Beijing-Hangzhou Grand Canal, the longest in the world, connected the five major water systems of the Haihe River, the Yellow River, the Huai River, the Yangtze River and the Qiantang River and the large area between Beijing and Hangzhou, and became the first transportation artery connecting the north and south in Chinese history.

The Panama Canal, which runs through Central America, is only a kilometer long, but it connects the two largest oceans, the Pacific and Atlantic oceans. It is a man-made river above sea level, 91,304 metres wide and deep, with six locks along the route to change the water level. After the canal is opened, it will pass through about 10,000 ships every year.

The Panama Canal is geographically important, but its size limits the tonnage of ships that can only be navigated to 45,000 tons. In contrast, the Suez Canal, which connects the Mediterranean Sea and the Red Sea, is the world's busiest sea-opening canal, connecting Europe, Asia and Africa by sea, greatly reducing the time and distance of navigation. The Suez Canal has been expanded to accommodate large ships with a draft of up to 16 meters and a full load of 150,000 tons (or 370,000 tons empty).

The Beijing-Hangzhou Grand Canal is the world's longest mileage, the largest ancient canal, but also one of the oldest canals, and the Great Wall, Karez known as the three great projects in ancient China, and used so far, is a great project created by the ancient Chinese working people, is one of the symbols of China's cultural status. [1] In the Spring and Autumn Period, the Wu Kingdom was excavated for the invasion of the Qi State, and the Sui Dynasty greatly expanded and penetrated to the capital Luoyang and Lianzhuo County, and the Yuan Dynasty abandoned Luoyang and took it until Beijing during the renovation. It has a history of more than 2,500 years.

In 2002, the Grand Canal was included in the eastern route of the South-to-North Water Diversion Project. The Grand Canal starts from Yuhang (now Hangzhou) in the south, reaches Zhuojun (now Beijing) in the north, passes through the four provinces of Zhejiang, Jiangsu, Shandong, Hebei and Tianjin and Beijing, and runs through the five major water systems of Haihe, Yellow River, Huai River, Yangtze River and Qiantang River, with a total length of about 1,797 kilometers. The canal has played a huge role in the economic and cultural development and exchanges between the northern and southern regions of China, especially the development of the industrial and agricultural economy along the route.

Introduction to the Beijing-Hangzhou Grand Canal.

1. The length of the Beijing-Hangzhou Grand Canal: With a total length of 1,794 kilometers, the Beijing-Hangzhou Grand Canal is the second "first-class waterway" in China after the Yangtze River, and its value is comparable to that of the Great Wall. It is the world's oldest and longest man-made canal, nine times longer than the Suez Canal (190 km) and 22 times longer than the Panama Canal (km).

2. The Beijing-Hangzhou Grand Canal flows through the area: the Beijing-Hangzhou Canal flows through the two cities of Beijing and Tianjin and the four provinces of Hebei, Shandong, Jiangsu and Zhejiang from north to south, and runs through China's five major water systems: Haihe River, Yellow River, Huai River, Yangtze River, Qiantang River and a series of lakes; From the North China Plain to the Yangtze River Delta, the terrain is flat, the rivers and lakes are intertwined, and the fertile fields are thousands of miles, which is the main grain, cotton, oil, sericulture and hemp production areas in China since ancient times. 3. Coastal customs:

The water of the canal not only carries the ships coming and going from the south to the north, but also nurtures and nourishes the children of the canal and the canal city along the coast. Canal-side buildings, such as guild halls, river ports, wharves, bridges, locks, and caoyun yamen, were built for practical use. There are also many folk customs along the canal, revealing the soul of pragmatism.

On June 22, 2014, the 38th session of the World Heritage Committee announced that China's Grand Canal project was successfully inscribed on the World Cultural Heritage List, becoming China's 46th World Heritage Site. A total of 27 sections of river heritage and 58 canal-related sites are included in the inscription. Reference: Encyclopedia - Beijing-Hangzhou Grand Canal.

When it comes to the Grand Canal, we should all be familiar with it. The Grand Canal can be said to be a great water conservancy building created by the working people in ancient China, but many people are not clear about what the role of the Grand Canal is, let's take a look.

The Grand Canal was founded in 486 B.C., including the Sui and Tang Dynasty Grand Canal, the Beijing-Hangzhou Dazao Brother Canal and the East Zhejiang Grand Canal, with a total length of 2,700 kilometers, spanning more than 10 latitudes on the earth, spanning Beijing, Tianjin, Hebei, Shandong, Henan, Anhui, Jiangsu, Zhejiang 8 provinces and municipalities directly under the central government, running through the North China Great Plain, reaching the Haihe River, the Yellow River, the Huai River, the Yangtze River, the Qiantang River five major water systems, is the main artery of north-south traffic in ancient China, and the history of the Grand Canal has continued for more than 2,500 years.

The Grand Canal of the Sui and Tang Dynasties is a canal dug from Hangzhou in the south to Beijing in the south with Luoyang as the center after the Sui Dynasty unified the north and south of China, the main purpose is to transport the materials needed for the capital, and it has also become an important link to communicate the politics, economy and culture along the Grand Canal.

The Beijing-Hangzhou Grand Canal is one of the largest and oldest canals in the world, and is known as the two great projects of ancient China along with the Great Wall. It is a waterway transportation trunk line running through the north and south in order to ensure that the materials from the south can be continuously transported to the capital.

The Grand Canal of East Zhejiang Province is a canal in Zhejiang Province, with Shaoxing as the center, starting from Xiaoshan in the west and Ningbo in the east, and was built in the Spring and Autumn Period. The Southern Song Dynasty built the capital of Shaoxing, the imperial tomb is also in Shaoxing, and the Shaoxing section of the Zhaozheng Canal in the eastern mainland of Zhejiang became the royal river at that time, and it was also an important trade channel, and it was an important water transportation channel in Shaoxing.

The Grand Canal brought convenience to transportation, promoted the development of agriculture and the prosperity of commerce. It has served as an important channel for China's submarine transportation for more than 1,200 years. In 1911, the Jinpu Railway was opened to traffic, and the Grand Canal gradually fell into oblivion.

However, because it has played a great role in the wealth of half the world, and the Grand Canal is still the pride of the Chinese.
