Traditional revetment has a strong function but weak ecology, and the material and energy exchange before and after revetment is blocked, so it is difficult to meet the needs of green and ecological channel construction in the new era.In view of this problem, this paper takes the channel regulation project of Youdun Port in Shanghai as an example and analyzes the construction conditions, engineering characteristics, and ecological revetment concept.In addition, the paper puts forward a respiration-type prefabricated ecological revetment structure and summarizes technologies such as ecology design, hydrophilicity design, and joint connection design, as well as calculation method, so as to provide a reference for the construction of a faster and better green channel.
