| description | Huanggang is one of the areas with frequent geological disasters in the flood season in Hubei Province. The main types of geological disaster are landslides, accounting for 75% of rainfall-induced landslides. Therefore, this paper statistically analyzes the correlation between rainfall and landslides in Huanggang City over the last 10 years, studies the rainfall threshold of rainfall-induced landslides in Huanggang City based on considering the prone zoning of geological disasters, establishes the effective rainfall model of landslide occurrence by using the logistic regression model and then puts forward the corresponding meteorological early warning criterion for different prone zone areas. Finally, the rationality and reliability of the early warning criterion are tested by historical rainfall and landslide events. The results show that the meteorological early warning criterion established significantly improves the accuracy of meteorological early warning for rainfall-induced landslides in Huanggang City, provides refined technical guidance for disaster transfer, and effectively reduces the loss of life and property caused by rainfall-induced landslides. |
