Analysis of Research Trends in Future Underwater Independent Cities : Based on the analysis of CiteSpace Literature Metrology

Against the backdrop of global climate change and rising sea levels, underwater independent cities are widely attracting attention as potential solutions to cope with urbanization and ecological crises. In this study, the literature on underwater independent cities from 2000 to 2023 was systematically organized and analyzed using the CiteSpace literature measurement method. The core topics of this field, research focus, and future development directions were presented through literature inquiry trends, keyword presentation analysis, and literature official analysis. According to the results of the study, future underwater independent cities have important potential in coping with the challenges of climate change and urbanization, and future studies should focus on the synergy effect of technological innovation and policy support. Despite significant progress, existing research focuses primarily on the technical level and lacks in-depth exploration of the role of design in driving the development of independent cities on water. This study clarifies the core value and practical significance of design in the future water independent urban development, and provides theoretical basis and direction for promoting sustainable, ecological and intelligent urban design.
