Abstract

The invention relates to a stability evaluation method and apparatus for a landslide prediction model. The method comprises a factor selection step, a combination generation step, and a stability evaluation step of obtaining an ROC curve, based on different combinations, of the landslide prediction model by applying test data and evaluating the stability of the landslide prediction model according to the ROC curve. The method and the apparatus are used for evaluating the stability of the landslide prediction model, and a model with relatively high stability is used for performing landslide prediction, so that the landslide prediction accuracy can be improved; and the model with relatively high stability can be obtained through the method according to the landslide prediction model of any region.

Description

technical field [0001] The invention relates to the field of monitoring of natural disasters, in particular to the monitoring of landslide risk, in particular to a method and device for evaluating the stability of a landslide prediction model. Background technique [0002] Earthquakes are a dangerous natural disaster, and their frequency increases every year. Keefer (1984) pointed out that many landslides were triggered by earthquakes greater than Ms4.0. These landslide hazards induced by earthquakes not only threaten people's normal life to a great extent, but also seriously affect the economic development of cities. Therefore, accurate prediction of such hazards becomes particularly important. [0003] In this field, landslide susceptibility mapping is an effective tool to help people understand and map future landslide hazards. Many algorithms (such as logistic regression, artificial neural networks, decision trees, analytic hierarchy process, support vector machines, ...
