Urgent question!! A famous water conservancy project built around 560 BC

Is it referring to Dayu's water control.

It could be a well canal, or Wang Jingzhi Yellow River.

It is the water conservancy project of the ancient city of Liangzhu, about 5,000 years ago, and even 1,000 years earlier than Dayu's water control.

The Liangzhu Water Conservancy System, located in Pingyao Town, Yuhang District, Hangzhou, is the earliest existing large-scale water conservancy project in China and the earliest flood dam system in the world.

Does the Three Gorges Water Conservancy Project count?

I don't know, I thought it was Dujiangyan.

Dujiangyan Dujiangyan (Dujiang Yàn), located in the west of Dujiangyan City, Sichuan Province, is a large-scale water conservancy project built and used in ancient China, known as the "originator of the world's water conservancy culture", and is a famous tourist attraction in Sichuan. It is generally believed that the Dujiangyan Water Conservancy Project was built by Li Bing, the Taishou of Shu County of Qin State, and his son around 256 BC, and it is the world's oldest and only surviving grand water conservancy project characterized by water diversion without dams, and it is a national key cultural relics protection unit.

The establishment of Dujiangyan has its specific historical roots. During the Warring States Period, the people who suffered from the war were eager for the reunification of China as soon as possible. Coincidentally, the Qin State, which had undergone the reform of the Shang Dynasty, was famous and virtuous for a while, and the country was flourishing.

They correctly recognized the special strategic position of Ba and Shu in the unification of China, and "if Shu is gained, Chu will be won, and if Chu is lost, the world will be united" (Qin Xiang Sima mistake). In this historical context, at the end of the Warring States Period, King Qin Zhao appointed Li Bing, who knew astronomy, geography, and lived in seclusion, as the county guard of Shu. After Li Bing took office, he first made up his mind to fight the floods of the Minjiang River, develop agriculture in western Sichuan, benefit the Chengdu Plain, and create an economic foundation for Qin's unification of China.

In the fifty-first year of King Zhaoxiang of Qin (256 B.C.), Li Bing, the Taishou of Shu County of Qin, and his son, learned from the experience of their predecessors in water control, led the local people, and presided over the construction of the famous Dujiangyan Water Conservancy Project. The overall plan of Dujiangyan is to divide the water flow of the Minjiang River into two, one of which will be introduced into the Chengdu Plain, so that it can not only divide the flood and reduce the disaster, but also divert water to irrigate the fields and turn the harm into benefit. The main works include the fish mouth diversion embankment, the flying sand weir spillway and the water intake of the treasure bottle.

Lingqu Lingqu is one of the oldest canals in the world in Xing'an County, Guangxi Zhuang Autonomous Region, and has the reputation of "the pearl of ancient water conservancy architecture in the world". Lingqu was called Qin chiseled canal, zero canal, steep river, Xing'an canal in ancient times, and was dug into navigation in 214 BC, 2217 years ago, and still plays a role. The Ling Canal was dug in 214 BC (Qin Dynasty).

The Nanling Mountains across the border of Hunan and Guizhou are scattered, and the upper sources of the Xiang River and the Li River are very close to each other. Located in Xing'an County, Guilin, the watershed near Xing'an City is a famous ancient water conservancy project in China and one of the oldest canals in the world, which connects the Xiangjiang River (Yangtze River water system) and the Li River (Pearl River water system), and plays an important role in the development of Lingnan.

Hangou Hangou is an ancient canal connecting the Yangtze River and the Huai River, and it is the earliest canal in China that can be seen in a clear record. It was the Spring and Autumn Period, a "ditch" connecting the Yangtze River and the Huai River was dug near Yangzhou in the Wu Kingdom. It is also known as canal water, Hanjiang River, Zhongdu water, Shanyang canal, Huaiyang canal, Li canal.

Hangou starts from the Yangtze River south of Yangzhou in the south and reaches the Huai River north of Huai'an in the north. At the beginning of the ditch excavation is used for the military, the end of the mouth chokes the ditch into the mouth of the Huai, for the hub of the four major water systems of the river, the Huai, the river and the Ji, not only the key point of transportation, and the war in the Jianghuai region, must fight for Huai'an. For a long time, Huai'an has been an important military town where "the south must get and then forge ahead and have capital, and the north must get and then the salary is unimpeded".

During the Spring and Autumn Period and the Warring States Period, the most famous water conservancy project was Dujiangyan.

Dujiangyan is located in Sichuan.

Quancheng West, Dujiangyan City, Chengdu City, Chengdu Province, is located on the Minjiang River in the west of the Chengdu Plain, was founded in the last year of King Qin Zhao (about 256 BC before 251), is the Shu County Taishou Li Bing father and son in the ancestors of the turtle spirit on the basis of the organization of the construction of large-scale water conservancy projects, by the water fish mouth, flying sand weir, treasure bottle mouth and other parts, more than 2,000 years has been playing the role of flood control and irrigation, so that the Chengdu Plain has become a water and drought from people, fertile fields for thousands of miles"The land of abundance"So far, the irrigation area has reached more than 30 counties and cities, covering an area of nearly 10 million acres, and it is the world's oldest so far, the only one that has survived, and is still in use, and is characterized by the diversion of water without dams, which embodies the crystallization of the diligence, courage and wisdom of the working people of the Han nationality in ancient China.

Dujiangyan, Zhengguo Canal, Hangou, Gap, Lingqu are from the Qin Dynasty.

Dujiangyan of Li Bing of the Warring States Period, Yeshui made by Ximen Leopard, and Zheng Guoqu in Guanzhong.

Dujiangyan Qin State Shu County Shou Li Bing presided over the construction.

Dujiangyan is followed by: Zhengguo Canal, Ling Canal.

If memory serves, it should be Dujiangyan.

Dujiangyan was built by Li Bing and his son in the Qin State during the Warring States Period (2 points).

Dividing water fish mouth", "flying sand weir", "treasure bottle mouth"; (2 points) Flood discharge and irrigation (2 points).

It can irrigate tens of millions of acres of land, and has become the largest, most effective and longest-lasting water conservancy project in ancient China. It represents the advanced level of water conservancy projects in China at that time and is the crystallization of the wisdom of the ancient working people.

Test question analysis: The first question mainly examines the construction of Dujiangyan, and reviews the knowledge that has been learned, it can be seen that Dujiangyan is a large-scale water conservancy project presided over by Li Bing and his son in the Minjiang River basin during the Warring States Period.

The first question is to examine the components of Dujiangyan, and from the knowledge learned, it can be known that the "water dividing fish mouth" is built in the river, so that the river water is diverted from both sides. The inner river in the east is used for irrigation, and the outer river in the west is used for flood diversion. "Flying sand weir" is the flood discharge and sand discharge facility of Dujiangyan, when the rain is heavy in summer, the water of the inner river can flow through the "flying sand weir" into the outer river, so as to protect the irrigation canal of the inner river from flooding.

Water from the Neijiang River is channeled into the tributaries through the "treasure bottle" and used to irrigate farmland.

The first question is to test students' accurate understanding of the significance of the construction of Dujiangyan, and it can be seen that Dujiangyan still plays an important role in connection with the knowledge learned, which can irrigate tens of millions of acres of land, and has become the largest, most efficient and longest-lasting water conservancy project in ancient China. It represents the advanced level of water conservancy projects in China at that time and is the crystallization of the wisdom of the ancient working people. Therefore, Dujiangyan will be listed as a "world cultural heritage" in 2000.
