Urban renewal, resilient city construction, protection and restoration of water ecosystems are important issues in the construction of ecological civilization in the new era of China. Waterfront space is an important spatial element for the coordinated development of urban and rural life, production and ecology, which also has a great impact on the quality, environment and ecology of the city. At the same time, the ecological restoration of the waterfront space is closely related to the "double-carbon" goals and promotes each other. This article summarizes the construction of water-suitable cities and reviews the research results of waterfront space among ecological restoration, planning and construction, operation, and management, new technology application and technical specification guide in 2021. On this basis, it proposes that the future research of urban planning and construction should further strengthen the waterfront space value enhancement and the methodology construction of ecological restoration. In addition, interdisciplinary integration and application of new technologies are still important in the future research, and introduction and practice of international advanced concepts should also be emphasized.
