Geohazard susceptibility mapping considering spatial heterogeneity: a case study of xide county in sichuan province

HIGHLIGHTS

  • What: To ensure that the research results have reference value, this study takes Xide County as an example, based on the frequency ratio model (Fan et_al, 2019; tang et_al, 2022; yan et_al, 2019) focused on the division of the study area and the selection of evaluation factors under the influence of spatial heterogeneity, and explored new ideas for susceptibility mapping analysis. The semi-quantitative zone scheme based on the hazard-pregnant environment has dealt with the spatial heterogeneity of the study area to a certain extent, and the zone results are scientific and reasonable, which lays a . . .
