Abstract: Based on the geological disaster and precipitation data from 2008 to 2022, the temporal and spatial distribution characteristics of geological disasters in Nujiang Prefecture of Yunnan are explored, and the relationship between geological disasters and precipitation are revealed. The results show that the geological disasters were of obviously the temporal and spatial variation characteristics. From the perspective of time change, the number of geological disasters was the largest in 2010, followed by 2016. The geological disasters mainly occurred in spring and summer, and the peak period appeared in April and July. The spatial distribution characteristics of geological disasters in Nujiang Prefecture were obviously more in the north and less in the south. The main geological disasters in Nujiang Prefecture were the debris flow, landslide and collapse, and the debris flow was the most, and there were large spatial and temporal differences in the distribution of different geological disasters. The temporal and spatial distribution of geological disasters coincided with those of precipitation. During the occurrence of geological disasters, the rainfall levels were mainly light rain, heavy rain and torrential rain, which indicated that precipitation was the main meteorological factor causing geological disasters.
