Abstract

The embodiment of the invention discloses a natural disaster comprehensive risk assessment method and device, computer equipment and a storage medium. The method comprises the following steps: extracting features of each evaluation index based on an artificial intelligence algorithm to obtain evaluation features; performing model training through a machine learning algorithm according to the evaluation features to obtain an evaluation model; comprehensively considering the relation between single disaster species and the vulnerability of a hazard-affected body according to the assessment model to obtain a comprehensive risk assessment result; and carrying out risk division according to the comprehensive risk assessment result. By implementing the method provided by the embodiment of the invention, the interpretability of risk assessment is enhanced, the vulnerability and the exposure of the hazard-affected body are considered, the input information of the model comprises the risk of a single disaster, the vulnerability and the hazard-affected capability of the hazard-affected body and the relationship among multiple disasters, the input information of the model is sufficient, and the relationship and interaction between disaster-inducing factors are considered comprehensively.

Description

technical field [0001] The present invention relates to a natural disaster risk assessment method, and more specifically refers to a natural disaster comprehensive risk assessment method, device, computer equipment and storage medium. Background technique [0002] The comprehensive risk assessment of natural disasters refers to the comprehensive assessment of the total risk under the influence of various disaster-causing factors in the region by using certain theories and methods. The main purpose of natural disaster comprehensive risk assessment is to provide stakeholders or decision makers with the overall risk status of the region, formulate regional utilization plans, and arrange disaster prevention and mitigation funds to achieve the purpose of effectively reducing disaster risks. The comprehensive risk assessment of natural disasters is based on the study of single-hazard risks, but the assessment method is more complicated because it involves multiple disaster-causing...
