Studying the propagation of meteorological drought to hydrological drought is essential for meteorological information-based drought management and hydrological drought warning systems. Taking the Ganjiang River source basin as an example, this paper uses the basin's monthly meteorological and hydrological data for the past 60 years to study the propagation pattern of meteorological drought to hydrological drought, and explores the differences in drought propagation among sub-basins. The results show that the propagation of meteorological drought to hydrological drought has various ways, with a one-to-one correspondence; The drought events increase hazards after propagation from meteorology to hydrology; The Logistic model can better reflect the response relationship of hydrological drought characteristics to precipitation shortage conditions; The large reservoirs have a significant effect on the drought resistance of the basin.
