Evaluating the Susceptibility of Landslides and Collapse Based on the Information Content Model
The assessment of the susceptibility of regional geological hazards can provide a reference basis for their prevention and control.Based on the analysis of the geological condition and formation mechanism of disasters,this article selects evaluation factors that are closely related to the development of landslides and collapse,calculates the total information content of the evaluation factors related to the occurrence of geological disasters in each evaluation unit as the susceptibility index of geological disasters in this evaluation unit based on the information content model,and uses the natural breakpoint method to divide it into four levels:high susceptibility,medium susceptibility,low susceptibility and non susceptibility,in order to obtain the evaluation results of the susceptibility of landslides and collapse in Qiannan Prefecture.
