摘要

Against the backdrop of global warming and accelerated water cycling, drought flood abrupt alternation (DFAA), as an extreme compound hydro-meteorological event, is characterized by strong suddenness and complex disaster-forming mechanisms, posing severe challenges to ecological security and food security. This study drew upon the Web of Science Core Collection database to identify 140 core publications related to DFAA from 2010 to 2025, thereby ensuring the high quality and representativeness of the data; consequently, these 140 core publications are capable of reflecting the major research trends in this field. By combining CiteSpace and VOSviewer software for bibliometric visualisation analysis, and conducting a systematic review across three aspects—discrimination methods, causal studies and disaster impacts—this study aims to provide a macro-level quantitative analysis of current trends and the evolution of research hotspots in the DFAA field, thereby filling gaps in existing research. The results indicate that: (1) There is a clear upward trend in the prominence of DFAA, with China’s publication output in this field increasing year on year. Research hotspots have evolved from a single climatic feature to ‘soil moisture’ and ‘global warming’. (2) The construction of existing DFAA indices has gradually shifted from a single precipitation factor to incorporate ‘soil moisture’ and ‘evapotranspiration’, with a trend towards finer temporal resolution. (3) DFAA is caused by the interaction between the atmosphere and terrestrial hydrology, whilst human activities, by altering surface properties, further exacerbate the severity of DFAA. (4) DFAA has a significant negative impact on crop yield, physiological growth, and soil nitrogen and phosphorus loss, and its effects are greater than those of single-factor drought or flood disasters. Current research remains deficient in terms of generalised identification methods and studies on socio-economic development. Future research should focus on: (1) developing a comprehensive DFAA index that integrates multiple timescales and factors; (2) conducting more quantitative analyses of the relative contributions of climate change and human activities (land use, urbanisation) to the frequency and impacts of DFAA; (3) systematically assessing the impacts of DFAA on the resilience of urban infrastructure and socio-economic development.
