Plant communities in mountainous cities play significant roles in revetment protection, sediment interception, water purification, ecological buffer, biodiversity conservation, and landscape quality improvement. Meanwhile, the local complex hydrologic conditions may pose adversity stress to the structure, function, and ecological process of these plant communities. This paper introduces the restoration practices of river revetments in the Jiulong Waitan section of Chongqing employing ecological planting strategies. First, a technical framework was proposed for the re-establishment of riparian herbaceous communities as the multilayered semi-natural meadows that were planted by strips and zones upon hydrologic conditions. Second, principles and modes of these ecological planting practices were elaborated. Third, an evaluation on the communities’ performance indicated that they could adapt to the complex hydrological conditions in mountainous cities, including sharp rise and fall of river level during summer floods, high temperature, and storm runoff. This study may provide a scientific reference for riverfront landscape optimization of the main stream of the Yangtze River, and a paradigm for the ecological conservation and the establishment of ecological barrier for the upper reaches.
