Influencing Factors Analysis and Zonation Model Research of Landslides in Loess Region

Abstract:

Landslides zoning is an effective method of avoiding losses resulted from landslides in the loess areas. In this paper, the most important factors influencing the loess landslides are analyzed. As the five most important impact factors inducing the landslides，earthquake, water, slope, land use and natural density are selected to build a classification model based on AHP method. We obtained three kinds of landslides zonation maps under seismic motion with different exceedance probabilities. Combined with actual exploration, the zonation of landslides in Tianshui city is consistent with actual situation, which indicates that the classification model and the selected factors are appropriate to the loess landslide zoning.
