With growing urban congestion， urban air mobility （UAM）， which brings urban mobility into a third dimension for more efficient urban travel， has become a global research focus today. To provide a detailed summary of the development status and critical issues for UAM， this paper conducts bibliometric analyses on relevant publications in the Web of Science database from 1993 to 2024 using visualization software， such as VOSviewer and CiteSpace. This study covers publication output， country collaboration networks， core institutions， co-citation analysis， high-frequency keywords， and thematic mapping. Together， these indicators outline the core scholarly development of the UAM field. The findings aim to help readers gain a clearer understanding of the current research landscape and identify promising directions for future exploration.
