Abstract: Based on the geological disaster data and precipitation data of meteorological stations in Yunnan from 2014 to 2020, precipitation-type landslides, debris flows and collapses are selected through the effective precipitation method, and the precipitation characteristics before the occurrences of the above disasters are analyzed. The results show that the precipitation-type geological disasters in Yunnan are mainly landslides, followed by debris flows and collapses. The precipitation types inducing three types of geological disaters include short-time heavy precipitation, short-term precipitation and long-term precipitation. The samples of landslides, debris flows and collapses caused by short-term precipitation accounted for 78%, 83% and 75% respectively; more than 75% of the above disasters happened after heavy precipitation events in the past three days, and the occurrence ratio of debris flows was as high as 96%. The short duration heavy precipitation that induces landslide and debris flow disasters mainly occurs in the first 12 hours, of which the time of heavy precipitation in landslide disasters is the most in the first 1−4 hours, and the time of heavy precipitation in debris flow disasters is the most in the first 1 hour. Landslides, debris flows and collapses are mainly caused by short-term heavy precipitation in most parts of Yunnan, especially in Nujiang Prefecture.
