This study focuses on a comprehensive analysis of landslide research literature over the past 30 years, utilizing bibliometrics and knowledge mapping technology. The research objects consisted of 17 680 Chinese landslide literature articles (1992−2021) obtained from the CNKI database and 11 350 English landslide literature articles (2016−2021) retrieved from the SCI database. By employing bibliometrics and knowledge mapping visualization techniques, this paper examines the development of landslide research in China, the contributions of Chinese scholars to international landslide research, and conducts a comparative analysis of Chinese and English literature. The results indicate that: (1) stability has been a consistent focus of landslide research in China, continuously expanding and evolving with the development of landslide research methods, subjects, triggering factors, and disaster prevention and mitigation demands. (2) Major geo-hazard events with well-defined occurrence times tend to become research hotspots for a certain period. (3) China holds a dominant position in international landslide research, accounting for 23.34% of the total publication output, with the top four research institutions in terms of publication output originating from China. (4) In the context of climate change, integrating remote sensing with machine learning and depth learning methods，the research hotspots in landslide studies encompass early identification, prediction, and early warning of geo-hazards, the mechanisms underlying typical geo-hazards, marine geo-hazards, reactivation of ancient landslides in mountain and canyon areas, as well as high-speed and long-distance chain geo-hazards. The research results provide an objective overview of the development of landslide research in China and the global landscape, offering valuable insights for advancing landslide hazard prevention and control technologies in China.
