Fine-Grid Forecast Model and Its Application to the Geological Hazard in Langao
摘要
Abstract
Due to its unique landform and variable climate,Langao country has relatively more geological disasters. In order to reduce the economic losses caused by disasters,a fine mesh model of the BP neural network for the early warning of geological di?sasters in Langao country is established,and geological hazards in the region are predicted and analyzed. Topographical features, formation lithology,topographic gradient,and rainfall are selected as evaluation indicators and GIS techniques are used to map the region's geological map into 368 2.5(km)*2.5(km)fine grids. On this basis,the rainfall level of each grid is calculated,and the hazard level and disaster level after the comprehensive addition of the hazards are used as training data for the model. After using this data to train and predict the geological disasters in Dadaohe town,Langao county,it is found that the forecast results are basi?cally consistent with the actual situation. Studies have shown that using this model for geological disaster prediction is more feasible.关键词
