Introduction to Dujiangyan:

Dujiangyan is a world cultural heritage (listed in the World Cultural Heritage List by UNESCO in 2000), a world natural heritage (Sichuan giant panda habitat), a national key cultural relics protection unit, a national scenic spot and a national AAAAA-level tourist attraction.

Dujiangyan is located in the west of Dujiangyan City, Chengdu, Sichuan Province, on the Minjiang River in the west of Chengdu Plain. It was built in the last years of Zhao Haoqi in the Qin Dynasty (about 256 BC ~ 25 BC1year). It is a large-scale water conservancy project organized by Li Bing and his son, the magistrate of Shu County, on the basis of excavating the turtle spirit of their predecessors. It is composed of a fish mouth, a flying sand weir, a bottle mouth and other parts, and has been playing the role of flood control and irrigation for more than 2000 years. Chengdu Plain has become a "land of abundance" with thousands of miles of floods and droughts. Up to now, the irrigation area has reached more than 30 counties and cities, covering an area of nearly 10 million mu. It is the oldest and only water conservancy project in the world. It is characterized by water diversion without dam, which embodies the diligence, courage and wisdom of the working people of Han nationality in ancient China.

Dujiangyan Scenic Area mainly includes Fulongguan, Erwang Temple, Anlan Cable Bridge, Yuleiguan, Lidui Park, Leiyushan Park, Yunv Mountain, Lingyan Temple, Zhao Pu Temple, Cuiyuehu Lake and Dujiangyan Water Conservancy Project.

water conservancy project

Dujiangyan Water Conservancy Project makes full use of the local geographical conditions of high northwest and low southeast, and according to the special topography, water veins and water potential of the river outlet, it takes advantage of the situation, does not build a dam to take water, and irrigates by gravity, so as to achieve the interdependence of dike, water diversion, flood discharge, sediment discharge and flow control, and give full play to the comprehensive benefits of flood control, irrigation, water delivery and social water use. Its biggest point is that the weir has been built for more than 2250 years, and it is playing an increasingly important role. After the completion of Dujiangyan, Chengdu Plain is fertile for thousands of miles. "Floods and droughts come from people, and there is no famine, so it is called abundance."

Dujiangyan canal head hub is mainly composed of three main projects: fish mouth, flying sand weir and treasure bottle mouth. The three factors cooperate organically, restrict each other, operate cooperatively, divert water for irrigation, divert flood and reduce disasters, and have the effect of "four-thirds and six-quarters, and relieve drought".

Minjiang Yuzui Water Diversion Project

Fish mouth diversion dike, also known as "fish mouth", is a diversion project in Dujiangyan, named after its fish mouth shape. It stands tall in the middle of the Minjiang River, including Baizhang Dike, Chacha Dike and Jingang Dike, and a series of facilities that cooperate with each other. Its main function is to divide the turbulent Minjiang River into two rivers. The outer river in the west, commonly known as the "Jinma River", is the positive flow of the Minjiang River and is mainly used for flood discharge; Neijiang, located at the foot of the eastern mountain, is an artificial water diversion channel, mainly used for irrigation.

In ancient times, fish mouths were made of pebbles in bamboo cages. Because it was built in the middle of the Minjiang River, the Minjiang River rushed out of the mountain pass, showing an arc circulation. In winter and spring, the river dried up, and the water bypassed the arc above the fish mouth, and the mainstream went straight to Neijiang. The inflow of Neijiang is about 60%, and that of Waijiang is about 40%. When the water level rises in summer and autumn, the water potential is no longer limited by the bend, and the mainstream goes straight to the outer river, and the proportion of incoming water from the inner river and the outer river is automatically reversed: about 40% from Neijiang and 60% from the outer river. This perfectly solves the needs of farmland water and people's domestic water in winter, spring and dry season in Neijiang irrigation area and the flood control problems in summer and autumn.

Dujiangyan architectural history:

The establishment of Dujiangyan opened a new era in the history of ancient water conservancy in China.

The establishment of Dujiangyan is based on the premise of not destroying natural resources and making full use of natural resources to serve mankind, turning harm into benefit, and making people, land and water highly coordinated and unified. It is the only great "ecological project" in the world so far. It initiated a new era in the history of ancient water conservancy in China, marked a new stage in the history of water conservancy in China and wrote a glorious chapter in the history of water conservancy in the world. Dujiangyan Water Conservancy Project is the crystallization of ancient people's wisdom in China, an epoch-making masterpiece of China culture and the only miracle of ancient water conservancy projects. Irrigation systems in ancient Egypt and Babylon, Lingqu in Zheng Guoqu, China, and Guangxi in Shaanxi, China, which were built almost at the same time, were lost or failed due to the change of the ocean and the passage of time. Only Dujiangyan is unique and has a long history of construction, which still nourishes the fertile soil of the land of abundance.
