Abstract

The application discloses a method, device and storage medium for determining landslide susceptibility distribution maps, which relate to the technical field of geology. The geographical index parameters are screened through the correlation between various geographical index parameters, thereby improving the determination accuracy. Accuracy of Landslide Susceptibility Maps. The method includes: obtaining the parameter values ​​of at least two geographic index parameters of each grid unit in the area to be predicted; obtaining the correlation between every two geographic index parameters in the at least two geographic index parameters through a preset correlation coefficient matrix model degree parameter; screen out the target geographic index parameter from at least two geographic index parameters based on the correlation degree parameter between every two geographic index parameters; determine the landslide susceptibility distribution of the area to be predicted according to the parameter value of the target geographic index parameter picture.

Description

technical field [0001] The embodiments of the present application relate to the technical field of geology, and in particular to a method, device and storage medium for determining a landslide susceptibility distribution map. Background technique [0002] As a common geological disaster, landslide has the characteristics of sudden outbreak, short duration and great harm, which seriously threatens the safety of human life and property. Therefore, determining the landslide susceptibility distribution map has become the key to the current disaster prevention and mitigation work. Through the landslide susceptibility distribution map, staff can quickly identify areas with high incidence of landslides. At present, the geographical index parameters in each region can be analyzed based on statistical principles to obtain the probability of landslides in each region, and then determine the landslide susceptibility distribution map based on the probability of landslides in each region...
