Flash floods are among the most dangerous natural disasters. As climate change and urbanization advance, an increasing number of people are at risk of flash floods. The application of remote sensing and geographic information system (GIS) technologies in the study of flash floods has increased significantly over the last 20 years. In this paper, more than 200 articles published in the last 20 years are summarized and analyzed. First, a visualization analysis of the literature is performed, including a keyword co-occurrence analysis, time zone chart analysis, keyword burst analysis, and literature co-citation analysis. Then, the application of remote sensing and GIS technologies to flash flood disasters is analyzed in terms of aspects such as flash flood forecasting, flash flood disaster impact assessments, flash flood susceptibility analyses, flash flood risk assessments, and the identification of flash flood disaster risk areas. Finally, the current research status is summarized, and the orientation of future research is also discussed.

山洪暴发的遥感与地理信息系统应用研究

山洪是最危险的自然灾害之一。随着气候变化和城市化进程的推进，越来越多的人面临山洪暴发的危险。在过去的20年中，遥感和地理信息系统（GIS）技术在山洪泛滥研究中的应用显着增加。本文对过去20年发表的200多篇文章进行了总结和分析。首先，对文献进行可视化分析，包括关键词共现分析，时区图分析，关键词爆发分析和文献共引分析。然后，从山洪预报，山洪灾害影响评估，山洪敏感性分析等方面分析了遥感和GIS技术在山洪灾害中的应用，评估山洪灾害风险，并确定山洪灾害风险区域。最后，总结了当前的研究现状，并对未来的研究方向进行了探讨。
