Dujiangyan, located in Dujiangyan City, Chengdu, Sichuan Province, is a UNESCO World Heritage Site and a World Heritage Irrigation Structure. It is one of the greatest hydraulic engineering projects in ancient China, renowned for its ingenious design and long history, hailed as a "Miracle of Ancient Hydraulic Engineering."
History and Background
Historical Origins
Dujiangyan was built in 256 BC by Li Bing and his son, governors of Shu Prefecture during the Qin Dynasty, and has a history of over 2,200 years.
Its construction not only solved the flooding issues in the Chengdu Plain but also provided a stable water source for local irrigation, earning it the title of "The Lifeline of the Land of Abundance."
Cultural Significance
Dujiangyan is a testament to the technological and intellectual achievements of ancient China, embodying the concept of harmonious coexistence between humans and nature.
In 2000, Dujiangyan was inscribed on the UNESCO World Heritage List, becoming a global model for hydraulic engineering.
Main Attractions
Yuzui Bypass Dam
The Yuzui Bypass Dam is the core structure of Dujiangyan, shaped like a fish's mouth, dividing the Minjiang River into inner and outer streams.
The inner stream is used for irrigation, while the outer stream is for flood discharge, achieving a rational distribution of water resources.
Feishayan Spillway
The Feishayan Spillway is a sand-discharging structure that uses the natural force of water to flush sediment into the outer stream, ensuring clear water in the inner stream.
This design showcases the advanced wisdom of ancient hydraulic engineering.
Baopingkou
Baopingkou is the inlet of the inner stream, shaped like a bottle's mouth, controlling the water flow into the Chengdu Plain.
Its precise design ensures a stable water supply for irrigation.
