Science and technology literature can fully reflect the development trend of scientific research, and the bibliometric method can be used to reveal the research frontier and hot issues. This paper, from the perspective of the bibliometric and based on the theme of mountain torrents disaster published in the network publishing database of China National Knowledge Infrastructure (CNKI) and Web of science, uses Co-word Analysis Method and Cluster Analysis Method and Multidimensional Scaling Analysis of related literatures to reveal the status of mountain flood disaster areas in recent 20 years. The results show that. (1) The research on mountain flood disaster is driven by disciplinary development and social needs. (2)Research hotspot focuses on two aspects of influence and defense.
