Abstract

The invention discloses a landslide susceptibility distribution map determination method and device and a storage medium, and relates to the technical field of geology. The method screens geographic index parameters through relevance among various geographic index parameters so as to improve the accuracy of the determined landslide susceptibility distribution diagram. The method comprises the following steps: acquiring parameter values of at least two geographic index parameters of each grid unit of a to-be-predicted region; acquiring a correlation degree parameter between every two geographic index parameters in the at least two geographic index parameters through a preset correlation coefficient matrix model; screening out a target geographic index parameter from the at least two geographic index parameters based on a correlation degree parameter between every two geographic index parameters; and determining a landslide susceptibility distribution map of the to-be-predicted area according to the parameter value of the target geographic index parameter.

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...
