Why were the two famous water conservancy projects built in the territory of Qin during the Warring

1) The reason why the two major water conservancy projects were built in the Qin State:

The Shang Dynasty reform promoted the economic development of the Qin state.

The Qin State attached great importance to water conservancy construction.

The Qin State is located in the west, and the territory is extremely rich in water resources.

Qin's cause of unifying the world needed sufficient grain as logistical support.

2) Influence on the development of Qin:

The Chengdu Plain and the Guanzhong region became famous granaries, greatly improving Qin's economic strength.

It laid an important material foundation for Qin's unification of the world.

Because of the Shang Dynasty Reform Law The Shang Dynasty Reform Law is mainly divided into two parts: Economy and Politics Among them, the economic reform measures mainly include the following points: 1) Waste well fields and open up the land 2) Emphasize agriculture and suppress business, and reward cultivation and weaving 3) Unified weights and measures In the final analysis, it is to emphasize agriculture and suppress business, and develop the feudal economy of the landlord class Water conservancy is the foundation of agriculture Because in ancient times, the main natural enemies of the agricultural economy were drought and waterlogging, and the construction of water conservancy projects was the main means to solve this problem, so it is not surprising that what you said As for the impact on the Qin State, it is self-evident The People Take Food as Heaven, the Kingdom Takes Agriculture as the Foundation The strength of a country in ancient China was mainly determined by its agricultural foundation.

Answer, the Shang Dynasty reform law promoted the economic development of the Qin State, 2, the Qin State attached great importance to water conservancy projects3, located in the western part of the water conservancy resources are more abundant4, the cause of Qin's unification of the world needs sufficient food and manpower as a guarantee.

What impact did this have on the development of the Qin state?

Answer, making the Chengdu Plain and the Guanzhong Plain famous granaries2 increased the economic strength on a large scale, provided a solid material foundation for the Qin unification war3, and raised and improved the lives of the Qin people.

The construction of the Zhengguo Canal was originally a tired plan for South Korea. The king of Han was deeply disturbed by Qin's continuous attacks on Korea, so he sent the engineer Zheng Guo to Qin to meet Qin Wang Yingzheng and build an irrigation canal in Guanzhong. King Han's idea was to fatigue the Qin people and army by building the Zhengguo Canal and delay the attack on Korea.

King Qin didn't see that it was a tired Qin plan at first, so Zheng Guoqu began to build. But then Jeong-kook's plan was revealed. The King of Qin wanted to kill Zheng Guo, but Zheng Guo analyzed the King of Qin that Zheng Guoqu was actually good for the Qin State.

With it, Guanzhong can form a granary no less than the Chengdu Plain, which can improve the national strength of the Qin State. King Qin was moved. So the Zhengguo Canal was built.

After its completion, the Qin State really increased its national strength, but Korea perished even faster. Of the third floor of the reference, I said it in great detail.

Personally, I think that it was foreign spies who broke into the interior and consumed a lot of Qin's property and Qin's national strength.

The Qin State attached great importance to agriculture, and grain was the foundation of national strength.

Dujiangyan and Zhengguoqu.

Qin Shi Huang. Ying Zheng (259 BC - 210 BC), Ying surname, Zhao or Qin, Ming Zheng (one name "Zheng"), also known as Zhao Zheng, Zulong.

etc., the son of King Xiang of Qin Zhuang and Zhao Ji. An outstanding politician, military strategist, strategist, and reformer in ancient China, he was the first political figure to complete the unification of China, and the first monarch in China to be called emperor.

Ying Zheng was born in the state of Zhao.

The capital city was Handan, and then returned to the Qin State.

In 247 BC, he took the throne at the age of 13, and from 230 BC to 221 BC, he successively destroyed the six kingdoms of Han, Zhao, Wei, Chu, Yan and Qi, completed the great cause of unifying China and established a ** centralized power.

of the unified multi-ethnic state - the Qin Dynasty.

During the Warring States Period, the famous water conservancy project built by the Qin State was Dujiangyan.

In 256 BC, Li Bing took office in Shu County and saw with his own eyes the disasters brought by the severe local disasters to the people. Soon after he took office, he began to carry out large-scale water control work. He was not afraid of hardships and took his son Erlang to conduct field investigations along both sides of the Minjiang River to understand the water situation and topography, and gradually formulated a plan to control the flood.

Li Bing and his son, on the basis of their predecessors' water control, began to preside over the construction of the Dujiangyan Water Conservancy Project. They found that when the Min River entered the Chengdu Plain from a steep valley, the flow rate suddenly slowed down, and a large amount of sediment and rocks carried by the river water were deposited immediately, silting up the river. Once the water rises suddenly, it will naturally overflow.

It is planned to construct a water control project at this critical junction.

The design and planning of Dujiangyan is to divide the water flow of the Minjiang River into two and introduce one of the water flows 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 harm into benefit.

The Dujiangyan project includes three main parts: the Yuzui diversion embankment, the Feishayan spillway and the Baohuakou water inlet. Through the combined use of the water diversion fish mouth and the treasure bottle mouth, the flow of the Minjiang River in the flood period and the dry season can be reasonably distributed according to the needs of irrigation and flood control.

During the Warring States Period, two famous water conservancy projects were built in the territory of Qin: Dujiangyan and Zhengguo Canal.

Dujiangyan was built in 256 BC, while Qin Shi Huang reigned in 259 BC and 210 BC; The Ling Canal was built by the First Emperor during his conquest of Lingnan.

Therefore, the first emperor built two water conservancy projects, Dujiangyan and Lingqu.

During the Warring States Period, the world-famous flood control irrigation and water conservancy project built by the Qin State has been benefiting the people to this day. The works are:

a Lingqu. b Dujiangyan.

c Grand Canal.

d will lead to the river.

Answer: B Analysis: During the Warring States Period, the world-famous flood control and irrigation water conservancy project built by Li Bing and his son in Shu County, Qin State, has been benefiting the people so far, so B was chosen.

The Ling Canal is a water conservancy project dug in the Qin Dynasty, the Grand Canal is a water conservancy project dug in the period of Emperor Yang of the Sui Dynasty, and the Huitong River is a water conservancy project in the Yuan Dynasty.

During the Warring States Period, the Dujiangyan built by Li Bing, the Taishou of Shu County of Qin State, in the middle reaches of the Minjiang River, is a world-famous flood control irrigation project, which eliminates the flooding of the Minjiang River, irrigates a large area of farmland, and makes the Chengdu Plain become "water and drought from people, do not know hunger";

During the Warring States Period, the water conservancy project of the Qin State was the Dujiangyan Water Conservancy Project built by Li Bing and his son.

During the Warring States Period, the famous water conservancy project of the Qin State was Dujiangyan, and the water conservancy project built after the unification of Qin was the Ling Canal. Dujiangyan is located on the Minjiang River in the west of the Chengdu Plain, which is a large-scale water conservancy project built in the middle reaches of the Minjiang River by Li Bing, the Taishou of Shu County of Qin State, during the Warring States Period, and is also a world-famous flood control and irrigation project. Dujiangyan makes the Chengdu Plain become "water and drought from people, do not know hunger", condensing the crystallization of the bravery, diligence and wisdom of the ancient Chinese working people.

Legal basis

Farmland Water Conservancy Regulations

Article 2 These Regulations shall apply to the preparation and implementation of farmland water conservancy plans, the construction, operation and maintenance of farmland water conservancy projects, and farmland irrigation and drainage.

The term "farmland water conservancy" as used in these Regulations refers to engineering measures such as irrigation and drainage and other relevant measures taken to prevent and control drought, waterlogging, flooding, and salinity-alkali disasters in farmland and to improve agricultural production conditions.

The water conservancy projects in the Warring States period include: Dujiangyan, Grand Canal, and Zhengguo Canal. The project manager is responsible for the overall responsibility for the quality of the water conservancy project, that is, the project quality is the responsibility of the legal person.

The project legal person shall strictly implement the relevant documents of project quality management in accordance with national laws and regulations, set up a corresponding construction quality management leading group, and establish a responsibility system for quality management of development projects.

Water conservancy projects, including urban water supply projects, seaside reclamation projects, water conservancy and fishery projects, as well as hydropower projects and port projects. In addition to being used in farmland water conservancy, water conservancy projects also have the role of reservoir reinforcement. It can be used as a kind of building to retain water, and it can be used as a building for specialized hydraulics.

Water conservancy projects, its advantage is that it can prevent floods. It has a flood prevention effect for some low-lying cities, and can prevent floods from causing certain damage to agriculture. Moreover, it can solve the situation of water use and make the rational distribution and utilization of water resources.

If there is a shortage of water in the north, the south-to-north water diversion project can be used to solve the water shortage, so that the water resources can be more fully utilized.

Legal basisArticle 5 of the Regulations on the Quality Management of Water Conservancy Projects.

The Ministry of Water Resources is responsible for the quality management of water conservancy projects nationwide. Each river basin agency is responsible for the quality management of water conservancy projects under the jurisdiction of the river basin agency in its own basin, and guides the quality management of the local water administration department.

Although it was built by the Qin Dynasty, it has been used by future generations for thousands of years. (Note: Dujiangyan, Lingqu, and Zhengguo Canal were not all built during the Qin Shi Huang period).

1. Dujiangyan.

Dujiangyan is located in the west of Dujiangyan City, Chengdu City, Sichuan Province, is located in the west of the Chengdu Plain on the Minjiang River, was built in the last year of King Qin Zhao (about 256 BC 251 BC), is the Shu County Taishou Li Bing father and son in the predecessor turtle spirit excavation 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.

For more than 2,000 years, it has played the role of flood control and irrigation, making the Chengdu Plain a fertile field for thousands of miles from water and drought"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 been preserved, and is still in use, characterized by the diversion of water without dams, which embodies the crystallization of the diligence, courage and wisdom of the ancient Chinese working people.

2. Lingqu. The Ling Canal is located in Xing'an County, Guangxi Zhuang Autonomous Region, and was dug into navigation in 214 BC (during the reign of Qin Shi Huang).

The Ling Canal flows from east to west, connecting the Haiyang River (the source of the Xiangjiang River, flowing from south to north) in the east of Xing'an County and the Darong River (the source of the Li River, flowing from north to south) in the west of Xing'an County, which is one of the oldest canals in the world and has the reputation of "the pearl of ancient water conservancy architecture in the world".

3, Zheng Guoqu.

Zhengguo Canal is located on the north bank of the Jing River, 25 kilometers northwest of today's Jingyang County, Shaanxi Province. It diverts Jing water in the west and injects Luo water in the east, which is more than 300 miles long.

In the last years of the Warring States period, it was chiseled by the Qin State. It was built in 246 B.C. (the first year of the reign of King Qin) by Zheng Guo, a Korean hydraulic engineer, and was completed about ten years later.

The role of Zhengguo Canal is not only that it has exerted irrigation benefits for more than 100 years, but also that it has pioneered the irrigation of Jing and has had a profound impact on the irrigation of later generations.
