都江堰（Dujiangyan）坐落在成都平原西部的岷江上，距成都市约50公里，始建于公元前三世纪。它的独特之处在于无需用堤坝调控水流。两千多年来，都江堰一直有效地发挥着防洪与灌溉作用，使成都平原成为旱涝保收的沃土和中国最重要的粮食产地之一。都江堰工程体现了我国人民与自然和谐共存的智慧，是全世界年代最久、仍在使用、无坝控水的水利工程。

        Dujiangyan is located on the Minjiang River in the west of the Chengdu Plain, about 50 kilometers away from the city of Chengdu. It was built in the 3rd century BC. Its uniqueness lies in that there is no need to use dams to regulate the water flow. For more than two thousand years, Dujiangyan has played an effective role in flood control and irrigation, making the Chengdu Plain a fertile soil that ensures harvest against droughts and floods and one of China’s most important grain producing areas. The Dujiangyan Project embodies the wisdom of the harmonious coexistence of our people and nature. It is the world’s oldest water conservancy project that is still in use and controls water without the help of dams.
