| 科技文献能够充分反映科学研究的发展动态，通过文献计量的方法可以很好地提示学科领域的研究前沿与热点问题。为揭示近20年来山洪灾害领域的研究现状，本文从文献计量学的角度出发，以CNKI和web of sciece数据库为统计源，以“山洪灾害”为关键词，运用共词分析法、聚类分析法以及多维尺度分析法对国内的相关文献进行统计分析，结果表明：（1）山洪灾害的研究受到了学科发展和社会需求的双向驱动；（2）山洪灾害研究热点集中在影响和防御两个方面；（3）山洪灾害的研究形成了成因、影响和防灾减灾分析三大类群体，且三者之间联系紧密。 |

| 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.
