Abstract: Since July 2022, the Yangtze River basin has continued to have high temperature and little rain, less water from rivers, low water levels, insufficient water storage in small and medium-sized reservoirs, and soil moisture shortage in many places. Remote sensing technology can monitor and assess drought efficiently and on a wide scale. For the drought in Sichuan, Chongqing, Yunnan, Guizhou, Shaanxi, Hubei, Hunan, Jiangxi and Jiangsu provinces (Municipality) in the Yangtze River basin, based on the multi- source satellite remote sensing data and the data of the National Meteorological Administration, and through the GEE(Google Earth Engine) remote sensing cloud computing platform, the drought in the middle and lower reaches of the Yangtze River was dynamically monitored and analyzed by using the data of precipitation anomaly index, standardized precipitation index, remote sensing drought index, remote sensing soil moisture, and water body changes. The results showed that the drought in the Yangtze River basin in 2022 had a wide impact and long duration, and the precipitation and soil moisture content were more than 30% lower than the average of previous years, and the drought spread rapidly from the upper reaches of the Yangtze River to the middle and lower reaches of the Yangtze River. The drought has led to a sharp decrease in water supply in the Yangtze River basin, with the water body of Poyang Lake and Dongting Lake shrinking by more than 40% between June and August. Based on the drought, the Yangtze River basin still needs to promote the construction of water projects and optimize the dispatching of water resources, so as to improve the ability to cope with such high-intensity and long-term droughts.
