Abstract
A method and system for evaluating casualty caused by landslide chain disaster induced by heavy rain are provided. The method includes: obtaining historical landslide data, candidate influence factors and personnel traffic distribution data of an observation site; dividing the historical landslide data into a model construction sample group, a model verification sample group, and a model test sample group; obtaining an occurrence probability of landslide chain disaster of each spatial position in the observation site; determining a start-up landslide source region of the landslide chain disaster according to the model verification sample group and the occurrence probability; determining an affected region of the landslide chain disaster according to the start-up landslide source region; determining a personnel number exposed to the landslide chain disaster; and setting an event division threshold, and evaluating the number of casualties according to the event division threshold and the personnel number.
