Urban water ecosystem has always been a hot topic in flexible cities. The common hardened revetment will make the river lose its natural storage capacity, which is not conducive to the sustainable development of the ecological environment. In order to construct the revetment ecosystem, the forms of river revetment greening are gradually diversified, which is more than just a single function. Based on the perspective of ecology, this article analyzes the landscape of the completed river revetment, and summarizes the design priorities, plant cultivation, construction methods and maintenance points of the low-cost urban ecological revetment, in order to provide some reference for the design and construction of the ecological revetment landscape in northern cities.
