Dujiangyan is introduced as follows:

Dujiangyan, located in the west of Dujiangyan City, Chengdu, Sichuan Province, is located on the Minjiang River in the west of Chengdu Plain. It is a huge engineering system consisting of headwaters (Yu Zui, Sha Fei weir and Baokoukou), irrigation diversion channels at all levels, various engineering buildings, large and medium-sized reservoirs and ponds. The canal head covers an area of more than 200 mu.

It is responsible for the irrigation of more than 10,000 mu of farmland in 40 counties (cities, districts)1/kloc-0.3 in 7 cities in the central and western areas of Sichuan Basin, the domestic water supply of many key enterprises and cities in Chengdu, and the comprehensive services of flood control, power generation, bleaching, aquatic products, aquatic products, fruit, tourism and environmental protection. It is an irreplaceable water conservancy infrastructure for the development of national economy in Sichuan Province.

The functions of Dujiangyan are introduced as follows:

Dujiangyan is a large-scale water conservancy project with a long history and the only dam-free water diversion project in the world. Make full use of the local geographical conditions of high northwest and low southeast. According to the special topography, water vein and water potential of the river pass, it guides the situation according to the situation, does not build dams to divert water, and irrigates by gravity, so that dikes, water diversion, flood discharge, sand discharge and flow control are interdependent, and the system is * * *.

It ensures the full play of the comprehensive benefits of flood control, irrigation, water transportation 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.

The positioning of Dujiangyan is introduced as follows:

Dujiangyan is an important part of world cultural heritage, world natural heritage, world water conservancy project heritage, national key cultural relics protection units, national scenic spots and national AAAAA tourist attractions.
