Abstract: With rapid urbanisation and increasingly severe water environmental problems, understanding the research development of urban water pollution control and aquatic ecosystem restoration is essential for advancing urban water management and engineering practice. Publications from 2010 to 2024 were retrieved from the Web of Science Core Collection database. Bibliometric analysis was conducted using the Cite Space visualization tool to analysis publication trends, national and institutional research patterns, and the evolution of research topics. Patent data were further incorporated to examine technological innovation characteristics and engineering application potential. The results indicate that research output in this field has increased steadily, with an accelerated growth after 2016. China ranks first in terms of publication volume, whereas the United States and several European countries show higher academic influence based on average citation indicators. Universities and research institutes are the main research contributors, and relatively stable collaboration networks have gradually formed. Research topics have evolved from a primary focus on pollution control and water quality regulation towards advanced treatment technologies and nature-based aquatic ecosystem restoration. In addition, technological innovation exhibits clear stage-wise characteristics, and the major technology clusters identified from patent analysis are highly consistent with dominant research topics, indicating a gradual transformation of research frontiers into engineering applications and system integration. Overall, these findings provide a scientific basis for improving the understanding of the technological framework, optimizing future research arrangements, and promoting the integrated application of engineering technologies in urban water pollution control and aquatic ecosystem restoration.
