Abstract

The invention relates to the field of geological disaster prediction, in particular to a regional geological disaster trend prediction method, and the method comprises the following steps: S1, collecting historical data of a regional geological disaster, and obtaining basic geological disaster parameters including a geological disaster type parameter, a grade parameter, a spatial distribution parameter and a geological environment parameter before the disaster occurs; S2, training and obtaining a geological disaster trend prediction model / algorithm based on the geological disaster type parameters, the grade parameters, the spatial distribution parameters and the geological environment parameters before disasters occur; and S3, realizing prediction analysis of geological disasters in the region according to the current geological environment parameters based on a geological disaster trend prediction model / algorithm. The method can predict the geological disaster occurrence trend of theregion in a certain period of time in the future in advance, and is high in accuracy.

Description

Technical field[0001]The invention relates to the field of geological disaster prediction, in particular to a method for predicting the trend of regional geological disasters.Background technique[0002]Geological disasters refer to phenomena or events that cause sudden or gradual damage to the geological environment due to geological processes (natural, man-made or comprehensive), and cause loss of human life and property. In recent years, geological disasters such as mudslides, landslides, and landslides have occurred frequently, causing huge losses to people's lives and property. How to deal with various geological disasters, improve the disaster prevention of the whole society and reduce disaster losses is an urgent task facing us.[0003]At present, most of the geological disaster trend prediction for a long period and a certain area is based on qualitative prediction, which generally has the defects of low precision and poor accuracy of prediction results.Summary of the invention[...
