Application of coupling method of information model and Logistic regression model in geological hazard susceptibility evaluation of Xin'an River Basin
Remote sensing data combined with mathematical model to evaluate the geological hazard susceptibility in river basins can help to carry out geological hazard early-warning.This paper uses the method of information model and logistic regression model coupling method to carry out regional eo-logical hazard susceptibility evaluation in the Xin'an River Basin by using the basic data such as geo-graphic national data,multi-source satellite remote sensing image data,digital elevation model,as well as the thematic data of geology,soil and geological hazard,and selecting the impact factors of geologi-cal hazard.The results show that the coupling method of information model and Logistic regression model can take into account the correlation between the impact factors and ensure the reliability of the evaluation results of geological hazard susceptibility.The mentioned method is used to evaluate the sus-ceptibility zoning of geological hazards in the Xin'an River Basin.It is concluded that high and higher susceptibility areas are mainly distributed along both sides of rivers and roads with large human activity intensity.The results are consistent with the actual distribution characteristics of geological hazard points,which can provide reference for hazard prevention and reduction in the Xin'an River Basin.
