Asking for information about Dujiangyan city

Dujiangyan is a large-scale water conservancy project with a long history and the only dam-free water diversion project in the world. It is not only a great miracle of water conservancy engineering technology in China, but also a bright pearl of water conservancy engineering 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, takes water without dam, and irrigates by gravity, which makes dikes, water diversion, flood discharge, sand discharge and water control interdependent and ensures the full play of the comprehensive benefits of flood control, irrigation, water delivery and social water use. Dujiangyan includes two parts: canal head and irrigation area. The headwater project is located at 1 km to the west of Dujiangyan City, Sichuan Province, and is the central protected area of 23 1.5 hectares irrigation area. The main reasons for Dujiangyan's enduring are the scientific site selection of canal head, clever matching of engineering and topographic conditions, making use of the situation, advancing with the times, restricting each other, complementing each other, reasonable layout and complete and scientific system. The canal head project is selected at the top of Chengdu Plain, with an altitude of 726 meters, which is the commanding height of the whole irrigation area and receives rich and stable water resources in the upper reaches of Minjiang River. The headwork of the canal consists of three main projects, namely Yuzui diversion dike, Baokou water intake and Sha Fei weir spillway, as well as auxiliary projects such as Baizhang dike and herringbone dike. It is an ecosystem project integrating diversion, overflow and sediment discharge.

Its biggest point is that the weir has been built for more than 2250 years, and it is playing an increasingly important role. 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 cooperative and unified. It is by far the only great "ecological project" in the world. 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 and an epoch-making masterpiece of Chinese culture.

Compared with the famous water conservancy projects in ancient China, Dujiangyan is unique in conception, design and site selection. Guide the situation, conform to the times, and do not compete with water enemies. Economies of scale are unique. It is a great pioneering work of natural ecology, scientific culture and close cooperation between man and nature, which is unmatched by any other ancient water conservancy projects in China and even the world. In the world's ancient and famous water conservancy projects, the Naer-Hammurabi Canal built by the Kingdom of Babylon on the Euphrates River and the artificial channels in ancient Rome have long been abandoned, and only Dujiangyan is unique and sustainable.
