The complex geo-environment of China, characterized by extreme rainfall, earthquakes, floods, and expanding engineering activities, has led to increasing geo-hazard risks. Since 2003, China has pursued meteorological factor–based geo-hazard early warning, achieving notable societal and economic benefits. With the rise of bibliometric and visualization tools such as CiteSpace, research trends and knowledge structures in this domain can now be systematically examined. This study analyzes 1,040 Chinese papers (CNKI) and 856 international papers (SCI-Expanded) published over the past two decades. Through bibliometrics, co-word analysis, clustering, and hotspot detection, the research identifies major themes, evolutionary trends, and future hotspots in meteorological factor–based geo-hazard early warning.
