This study utilizes CiteSpace software to conduct a bibliometric analysis of 939 relevant articles from the WOS database published between 2010 and 2023, constructing knowledge maps to outline research hotspots and developmental trends. The results indicate that research on compound extreme events is mainly concentrated in the United States and China, with research hotspots including compound events such as “heat-drought” and “precipitation-heatwave.” The research process can be divided into three phases: the conceptual exploration and driving factor analysis phase (2010~2017), the multidisciplinary integration and model construction phase (2017~2020), and the application phase (2020~2023), covering practical fields such as disaster risk management and urban planning. Future research should further integrate multidisciplinary approaches. Pay attention to region-specific studies and develop advanced predictive models to improve the prediction accuracy and management efficiency of compound extreme events, thereby providing scientific support for addressing climate change.展开更多
