The Yinjiang Jihuai project is the largest cross -basin and cross -regional water resource allocation project in China after the South -to -North Water Diversion Project. The project achieved the main engineering water navigation on December 30, 2022. The second phase of the project also started construction on the same day.

This article will introduce this modern water conservancy miracle comparable to the “Beijing -Hangzhou Grand Canal” from the aspects of historical, planning, benefits, challenges and prospects.

The historical background of the project

The Jiangji Huai project is not a new thing that has risen, but an old project with a long history. As early as the Spring and Autumn Period, someone began to dig into the ditch and lead the Yangtze River to the Huaihe River. Why?

In order to facilitate transportation, irrigating farmland, and preventing flood disasters, in short, it is to make ordinary people live a good life. These ditch later became the JAC Canal and Jiangnan Canal, and it was a masterpiece of the construction of ancient Chinese water conservancy.

Later, when I came to the Sui Dynasty, Emperor Sui Wen wanted to transport the food in the south to the north, and ordered the excavation of the canal and the Yongji canal to lead the Yangtze River to the Huaihe River and the Yellow River. From the south to the north. These canals can not only meet the needs of military and administrative, but also promote economic and cultural exchanges in the north and south.

Later, after the Yuan Dynasty, Yuan Shizu wanted to play from Dadu (now Beijing) to Shangdu (now Inner Mongolia), and transformed Yongji Qu and extended it to Beijing.

This canal was the longest artificial waterway in the world at that time and one of the world’s cultural heritage. This canal can not only ensure the safety and comfort of the emperor’s travel, but also support important functions such as transportation, commerce, and culture of the Ming and Qing Dynasties.

Although we are talking about the Jiangji Huai Project and the Beijing -Hangzhou Grand Canal are all cross -waters, it is not the same thing.

First, their construction purpose is different. The Beijing -Hangzhou Grand Canal is mainly to facilitate the transportation and logistics between the north and the south, and it is also a symbol of political and culture.

In order to solve the problems of water resources in the Huaihe River Basin and the deterioration of water environment in the Huaihe River Basin and promote the development of economic and social.

Secondly, their construction methods are also different. The Beijing -Hangzhou Grand Canal uses the connection between the natural river and the lake, and has formed an artificial canal through excavation and dredging. The Yinjiang Jihuai Project uses modern technology and engineering technology. It has formed a artificial water traffic channel through the construction of a reservoir, pumping station, and water pipeline.

Therefore, the Yinjiang Jihuai project is the inheritance and development of traditional Chinese water conservancy culture, and it is also an important part of China’s modern construction. It is comparable to the “Beijing -Hangzhou Grand Canal” and surpassed the “Beijing -Hangzhou Grand Canal”. It is a modern water conservancy miracle with historical and strategic significance.

Construction of Yinjiang Jihuai Project

Above we talk about the historical origin of the Jiangji Huai project. Next, let’s talk about the specific content of this project. The Jiangji Huai project is divided into three segments: Guijiang Ji Chao, Jianghuai Communication and Jiangshui North. Does it sound a bit around? Don’t worry, I will explain it slowly.

Guide to the nest of the river is to lead the Yangtze River water to Chaohu. Why do you do this?

Because Chaohu is the fifth largest freshwater lake in China and the main water source of the Huaihe River. However, the water quality of Chaohu is very poor, and the phenomenon of water such as cyanobacteria often occurs, which affects the drinking water and fishery production of residents along the coast.

If you want to restore the Chaohu Lake, you must use the Yangtze River to dilute and wash the sewage of Chaohu. To do this, we must use two leading river hubs, one is called Liyang and the other is called the Phoenix neck. These two hubs are like two large faucets, which can control the flow and direction of the Yangtze River water.

Through these two hubs, we can divide the Yangtze River water into two lines, one entering the Chaohu from the west, and entering the Chaohu Lake from the east to form a circular water recovery system. In this way, the water of Chaohu can flow and increase the amount of water and water.

Jianghuai’s communication is to lead the Yangtze River water from Chaohu to the Huaihe River. The Huaihe River is the seventh largest river in China and the mother river of two provinces in Anhui and Henan.

However, there are very few water resources in the Huaihe River, and often dried up and flowing, which led to problems such as water shortage, electricity, and grain shortage in coastal areas. Therefore, it is necessary to use the water of the Yangtze River to supplement and increase the amount of water in the Huaihe River, so that the Huaihe River will restore the vitality.

So how do you lead the Yangtze River from Chaohu to the Huaihe River? It is also necessary to use two water -lifting hubs, one called Paihekou, and the other is Shushan. These two hubs are like two large pump stations, which can lift the Yangtze River water from a low place to high.

Through these two hubs, we can turn the Yangtze River water over the Jianghuai watershed and realize the miracle of “water flowing to high.” Then the Yangtze River water was injected into Lake Wabu (the source of the Huaihe River), and eventually flowed into the Huaihe River.

The river is delivered north, that is, the Yangtze River water is transported north from the Huaihe River. The Huaibei area is one of the most water -lacking regions in China and one of the poorest areas in Anhui Province. The population density here is high and the industrial is developed, but the groundwater is severely superb, which has led to problems such as land settlement and worsening water quality.

Therefore, we must use the Yangtze River water to improve and ensure the water supply demand in the Huaibei region, so that the people of Huaibei live a rich and beautiful life. So how do you send the Yangtze River from the Huaihe River to the north? We need to use several main tributaries on the north bank of the Huaihe River, such as Shafei River, Vortex, and Xiyu River.

These tributaries are like several large water pipelines that can transport the Yangtze River water to various cities and counties and towns. Through these tributaries, we can gradually improve the water ecological environment of the Huaihe River and its main tributaries, and improve water quality and water volume.

This is the introduction of the Jiangji Huai project. The total length of the water flow line of the project is 723 kilometers. The water supply range covers 13 cities in Anhui Province and 2 cities in Henan Province, with a total of 55 districts and counties.

It is expected that in 2030, the Yangtze River water is 3.303 billion cubic meters, and the amount of water in the Huai Huai is 2.136 billion cubic meters. This is equivalent to providing 400 cubic meters per year for 40 million people, which is equivalent to drinking two barrels of water per person per day.

The efficiency of Yinjiang Jihuai Project

Since the beginning of the construction of the Jiangji Huaihuai Project, it has achieved remarkable construction results since 2020.

According to the latest data in June 2023, the project has completed 80%of the total investment, 5 reservoirs, 12 pump stations, and 8 water pipelines have been built. The total length has reached 1,200 kilometers. 20 billion cubic meters of Yangtze River water.

These achievements have brought real benefits to the people of the Huaihe River Basin. First of all, the water protection capacity of the Huaihe River Basin has been improved. The Yinjiang Jihuai project is about 10 billion cubic meters of water to the Huaihe River each year, which is equivalent to one -third of the natural runoff of the Huaihe River.

According to statistics, the introduction of the Jiangji Huai project directly benefited the 40 million population and 20 million mu of cultivated land, so that the per capita water resources of the Huaihe River Basin increased from about 400 cubic meters to about 800 cubic meters, reaching the level of the middle rich country of water resources in the world of water resources. Essence

Promote the economic and social development of the Huaihe River. The Yinjiang Jihuai project provides sufficient water volume for the Huaihe River Basin, and meets the water demand for agriculture, industry, urban and ecological aspects.

It is estimated that the Jiangji Huaihuai project can create a direct economic benefits of about 50 billion yuan for the Huaihe River Basin each year, and the indirect economic benefits are about 100 billion yuan.

At the same time, the leading Jiang Jihuai project has also led to the development of related industries, such as water conservancy, electricity, transportation, tourism, etc., providing more employment opportunities and sources of income for the local people.

Improve the ecological environment of the Huaihe River Basin. By transporting the clean water source of the Yangtze River, the water quality of the Huaihe River has been improved by transporting the water source of the Yangtze River, reducing pollutant emissions, and restoring the ecological function of the Huaihe River.

According to monitoring, after the opening of the Jiangji Huai project, the water quality of the Huaihe River and the tributary of the Huaihe River have improved significantly, among which the dry flow water quality has reached or better than the national type III standard.

In addition, the Jiangji Huai Huai project also provides survival conditions for the ecological systems such as wetlands, forest land, and grassland, adds biodiversity and protects rare species.

The Jiangji Huai project is not only a great water conservancy project, but also a strategic project that is conducive to national security and social stability. It has provided strong water protection for my country’s economic development and people’s lives, and has also made important contributions to the construction and environmental protection of ecological civilization in my country.

In the future, the Jiangji Huai project will continue to play its huge potential and role. According to the plan, by 2025, the leading Jiangji Huai project will realize the annual water influence of 10 billion cubic meters and benefit 60 million people along the provinces along the line.

At the same time, the Yinjiang Jihuai project will also cooperate with other cross -watershed water adjustment projects to form a water resources allocation network covering the country to achieve the optimization and use of water resources and reasonably allocate.

In addition to the water conditioning function, the Jiangji Huai project will also carry out a number of comprehensive utilization projects, such as hydropower development, tourism development, fishery development, and irrigation development. These projects will further promote economic growth and social progress in regions along the route, and improve the sense of happiness and gain of the people.

In short, the Jiangji Huai project is a great cause to benefit the thousands of generations and a masterpiece to show the wisdom and creativity of the Chinese nation. It not only made the water of the Yangtze River moisturize the land of the Huaihe River, but also brought the light of the Chinese civilization.
