The Beijing-Hangzhou Grand Canal is one of the world's longest, largest and oldest canals. From Beijing (Zhuo County) in the north, to Hangzhou (Yuhang) in the south, through Beijing, Tianjin and Hebei, Shandong, Jiangsu, Zhejiang four provinces, through the Haihe River, the Yellow River, the Huai River, the Yangtze River, the Qiantang River five major water systems, the total length of about 1794 kilometers, excavation has been more than 2500 years of history. The Beijing-Hangzhou Canal has played a huge role in the economic and cultural development and exchanges between the north and south of China, especially the development of the industrial and agricultural economy and the rise of cities and towns along the route.

The Beijing-Hangzhou Grand Canal is also one of the oldest. Together with the Great Wall, it is known as the two great projects of ancient China, and is famous all over the world.

With a total length of about 1,750 kilometers, the Beijing-Hangzhou Grand Canal is the world's earliest, longest route and largest artificial canal.

The earliest excavation, the longest route, the largest project.

One of the longest, largest and oldest canals.

The total length of the Beijing-Hangzhou Grand Canal is about 1,794 kilometers. The Beijing-Hangzhou Shixiao Grand Canal, which was built in the Spring and Autumn Period, is the world's longest and largest ancient canal, and is also one of the oldest canals.

The Beijing-Hangzhou Grand Canal has been used so far, which is a great project created by the ancient Chinese working people and one of the symbols of China's cultural status. 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, and the main water source is Nansi Lake (Weishan Lake, Weishan County, Shandong Province), and the Grand Canal is about 1,794 kilometers long.

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. By 2012, the navigable mileage of the Beijing-Hangzhou Canal was 1,442 kilometers, of which 877 kilometers were navigable throughout the year, mainly distributed in the south of Jining City, Shandong Province, Jiangsu and Zhejiang provinces. The whole process of the "Beijing-Hangzhou Grand Canal" can be divided into seven sections:

Tonghui River, North Canal, South Canal, Lu Canal, Confession Buried Canal, Li Canal, Jiangnan Canal.

A canal is an artificially dug river, and its existence makes transportation more convenient. Many canals were built in ancient China, among which the famous one is the Beijing-Hangzhou Grand Canal, although it is not one of the ten most beautiful canals in the world, it is the longest canal in the world, with a total length of about 1,797 kilometers. As the world's largest ancient canal, the Beijing-Hangzhou Grand Canal is not only a shipping waterway, but also one of the symbols of China's cultural status.

The Beijing-Hangzhou Grand Canal was built in the Spring and Autumn Period of China's feudal society, with a history of about 2,500 years, it is China's world-famous Grand Canal, reflecting the diligence and wisdom of the ancient people of our country. With a total length of about 1,797 kilometers, the Beijing-Hangzhou Grand Canal links the five major water systems of the Haihe River, the Yellow River, the Huai River, the Yangtze River and the Qiantang River, and flows through 20 provinces and cities including Beijing, Tianjin, Hebei, Shandong, Jiangsu and Zhejiang, playing an unparalleled role in the cultural development and exchanges along the route.

Many of the world's major projects were built with a strong political purpose, and the Beijing-Hangzhou Grand Canal was no exception, and its existence, like the Great Wall, was to prepare for war. In the Spring and Autumn Period, the flames of war were raging, and the five hegemons of the Spring and Autumn Period all wanted to expand their territory, and the Wu State at that time dug this canal to transport the army and military supplies to the Qi State in Shandong in order to annex the Qi State.

If the construction of the Beijing-Hangzhou Grand Canal in the Spring and Autumn Period was for war, then a large part of the reason for the expansion of the canal in the Sui Dynasty was to develop the economy, after all, the Sui Dynasty had unified the world, and the people's living standards needed to be improved. So far, the construction of the Beijing-Hangzhou Grand Canal continues.

The construction of any great project cannot be completed overnight, and behind it is the sweat and even the lives of countless working people. In order to build this canal, Emperor Yang of the Sui Dynasty forced all Ding men over the age of 15 to serve, and also sent a big man to serve as a supervisor, resulting in thousands of migrant workers being overwhelmed and dying on the canal construction site. According to historical records, Emperor Yang of the Sui Dynasty mobilized 3.6 million manpower in one year, of which 2.5 million died during the construction process, and the construction of the Beijing-Hangzhou Grand Canal was a disaster for the working people.

The total length of the Beijing-Hangzhou Grand Canal is about 1,797 kilometers.

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.

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 the cities of Tianjin and Beijing, and runs through the five major water systems of Haihe, Yellow River, Huai River, Yangtze River and Tangtang River next to Qianchan.

In the Spring and Autumn Period, Wu was excavated for the invasion of 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 when it was renovated. 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.

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 the 46th World Heritage Site in China.

Answer]: a, d

The Beijing-Hangzhou Grand Canal was originally excavated in the period of spring and filial piety, connecting the five major water systems of Haihe River, Yellow River, Huai River, Yangtze River and Qiantang River, passing through Beijing, Tianjin and Hebei, Shandong, Jiangsu and Zhejiang provinces, with a total length of about 1,794 kilometers, and has a history of more than 2,500 years. Therefore, items b and c are correct, and item d is incorrect. The mistake in item A is that the dynasties that formed the four sections of Yongji Canal, Tongji Canal, Hangou and Jiangnan River were the Sui Dynasty, not the Tang Dynasty.

Therefore, AD should be selected for this question.

The total length of the Beijing-Hangzhou Canal is about 1,794 kilometers.

With a total length of 1,794 kilometers, the Beijing-Hangzhou Grand Canal is China's second "first-class waterway" 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).

The flow direction, water source and drainage and storage conditions of the Beijing-Hangzhou Canal are different in each section, which is very complex, and the flow direction is generally summarized into four nodes and two flow directions: the Tonghui River and the North Canal north of Tianjin (Haihe) in node 1 flow to the south; The South Canal and Lubei Canal between Node 1 and Node 2 Dongping Lake flow northward; The Lunan Canal, the Middle Canal and the Li Canal between the Yangtze River (Qingjiang) between node 2 and node 3 flow southward; The section between Node 3 and Node 4 between Danyang south of the Yangtze River flows northward; The section of the river south of Danyang (Jiangnan Canal) flows southward.

Beijing-Hangzhou Grand Canal Basin

The Beijing-Hangzhou Canal flows from north to south through the two cities of Beijing and Tianjin and the four provinces of Hebei, Shandong, Jiangsu and Zhejiang, 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, the fertile fields are thousands of miles, and it is the main grain, cotton, oil, sericulture, and hemp producing areas in China since ancient times.

It is densely populated, with a high degree of agricultural intensification and great production potential. In modern times, the Beijing-Tianjin, Tianjin-Pudong, Shanghai-Nanjing and Shanghai-Hangzhou railway and highway networks have been built one after another, which are closely connected with the canal; Industries have sprung up in various places along the line, and cities and towns are dense, which is the place where China's economic essence gathers.
