【 摘 要 】

Extreme precipitation event is one of the most extensive and harmful meteorological disasters in China and even the world. Discussing the research situation of extreme precipitation under the background of climate change can grasp the research status and hot spots in this field from a macro perspective and provide a reference for in-depth understanding of the causes and trends of extreme precipitation. Since 1992, the research on extreme precipitation has been gradually carried out, so this study systematically counts and analyzes the scientific literature from the CNKI database from 1992 to 2022 by bibliometric. It shows that the frequency and intensity of extreme precipitation events increase in the China monsoon region, and the regional differences are obvious. It also has a great impact on agricultural production and vegetation coverage. In addition, in recent years, scholars have gradually carried out research on the relationship between extreme precipitation and atmospheric circulation, especially the relationship between the spatial and temporal characteristics of extreme precipitation and ENSO events, which has become a new research hotspot. It is suggested that future studies should comprehensively analyze various influencing factors, quantitatively analyze the impact of extreme precipitation on agricultural production and vegetation coverage, and put forward corresponding solutions.
