Dujiangyan Scenic Area （Southeast Gate 2） — Attraction in Chengdu

The Dujiangyan irrigation system, located in the western portion of the Chengdu flatlands at the junction between the Sichuan basin and the Qinghai-Tibet plateau, is an ecological engineering feat originally constructed around 256 BC. Modified and enlarged during the Tang, Song, Yuan and Ming dynasties, it uses natural topographic and hydrological features to solve problems of diverting water for irrigation, draining sediment, flood control, and flow control without the use of dams. Today the system comprises two parts: the Weir Works, located at an altitude of 726m, the highest point of the Chengdu plain 1km from Dujiangyan City, and the irrigated area. Three key components of the Weir Works control the water from the upper valley of the Minjiang River: the Yuzui Bypass Dike, the Feishayan Floodgate, and the Baopingkou Diversion Passage. Together with ancillary embankments and watercourses including the Baizhang Dike, the Erwang Temple Watercourse and the V-Shaped Dike, these structures ensure a regular supply of water to the Chengdu plains. The system has produced comprehensive benefits in flood control, irrigation, water transport and general water consumption. Begun over 2,250 years ago, it now irrigates 668,700 hectares...

One of the best known water conservancy projects. As a native Chinese person, I recommend that you’d better find yourself a guide to explain how the magnificent project is designed and built and how it solved the flooding problems there 2000 years ago. Otherwise, this seems just a river to you. It is said that every year there are two big events here in Dujiangyan, one is the Festival of Releasing Water, usually near the Qingming Festival (Apr 5th), the other is the commemoration of the birth of Li Bing who was responsible for the construction of Dujiangyan, and the date if I remember it correctly, shall be the 25th of the sixth month in the Chinese...

Visited today this place. Guide Richu was us and explained very nicely. Visiting the Dujiangyan Irrigation System was an unforgettable experience. This 2,000-year-old UNESCO World Heritage site is not only a masterpiece of ancient engineering but also a place of great natural beauty. The system still works today, supplying water to the Chengdu plain, which is truly amazing. The walking paths, temples, and scenic bridges make the visit both educational and relaxing. Everything is well-maintained, with clear information boards in English and Chinese. Highly recommended for anyone interested in history, culture, or simply enjoying a peaceful...
