空间多尺度下安溪县滑坡易发性评价
Multi-scale spatial analysis of landslide susceptibility in Anxi County
摘要
Abstract
This paper presents an analysis of historical landslide data from Anxi County,Fujian Province,coupled with a spatial multiscale approach.In the assessment of landslide susceptibility,we employed a combination of the logistic regression model,information model,and the entropy weight method.The outcomes reveal that both the logistic regression model and the information model are better suited for large-scale landslide susceptibility evaluations.Notably,the logistic regression model exhibits slightly superior predictive performance compared to the information model.Furthermore,it is noteworthy that the information model yields more accurate results at the local scale as opposed to the regional scale while optimizing sample parameters based on data-driven information quantity models can achieve reasonable results.Subsequently,the entropy weight method,employed to assess the susceptibility of individual-scale landslides,also demonstrates its suitability in this context.The assess-ment outcomes have been validated through model testing and comparison with actual landslide occur-rences,and they exhibit a commendable level of accuracy.This research's findings can serve as a valuable reference for the assessment of landslide susceptibility.关键词
