Research progress and prospects of smart sponge cities

Abstract

[Objective] The ongoing urbanization and economic development in China have led to factors that have exacerbated the problem of urban waterlogging. These include the improper placement of drainage pipes, the inefficiency of drainage infrastructure, and the expansion of impervious surfaces. To further promote the digital and intelligent development of sponge cities, this study analyzes the research progress and development trends in the construction of smart sponge cities. [Methods] Firstly, relevant literature in recent years was reviewed to explore the connotation, fundamental characteristics, and development of smart sponge cities. Secondly, Internet of Things technology, its architecture, and key technologies used in the construction of smart sponge cities were highlighted. Finally, the problems and shortcomings of the current research and development of smart sponge cities were explained, and relevant suggestions for future development were given. [Results] The research found that in the process of collecting the underlying information of the smart sponge city, technical challenges remain, such as the durability of the sensor and the transmission of wireless communication technology with low power consumption. At the same time, various technological method, including Internet of Things technologies, geographic information system, building information modeling, big data mining and analysis, and digital twins, have broad application potential in sponge facility monitoring and emergency management. [Conclusion] Suggestions for overcoming the challenges in the development of smart sponge cities are as follows: comprehensive standards and technical specifications need to be established; cross-departmental coordination mechanisms should be created to enhance communication efficiency. Secondly, it is important to overcome core technological challenges and explore technological innovation. Finally, in the process of achieving smart construction, sponge cities need to focus on digital information security and explore diversified financing channels to reduce costs and increase efficiency. The construction of smart sponge cities is a development trend in China aim at accelerating the smart transformation of sponge city infrastructure.
