Abstract: In order to deeply understand the current global research hotspots and future trends on drought monitoring, based on relevant domestic and foreign literatures from 2000 to 2022, CiteSpace visualization tool was used to study the hot trends of drought monitoring from annual changes in the number of published papers, major publishing countries and institutions, hot publishing journals and papers, and keywords of published papers. The results showed as follows: ①The number of publications on drought monitoring increased year by year, but the number of publications in Chinese literature was significantly lower than that in foreign literature, and the number of publications in foreign literature increased rapidly in recent years; ②The main research countries and institutions of drought monitoring are directly related to the degree of drought impact on regions, and China occupies the second place in the number of publications, but it is necessary to increase the investment of relevant research institutions; ③Remote sensing and drought index are the monitoring focuses of Chinese researchers, while foreign researchers pay more attention to climate change and ecological vulnerability caused by drought, etc. At present, machine learning and model building have become the research hotspots of drought monitoring. It is expected that emerging technologies will play a greater role in drought monitoring in the future. The analysis results can provide some guidance for the key focus and journal selection of drought monitoring research.
