| Abstract: | The Bortala Region is one of the potential area suffering from serious geohazards，where geographical types are various and complicated.By means of existing data，field investigation，DEM and geological map of the Bortala region，the main geohazard distribution were studied and geohazard susceptibility coefficients was computed by 6 independent factors (elevation，slope，relief，gap density，annual rainfall，lithology）on ArcGIS as a platform.Based on the geohazard susceptibility coefficients，the study area was divided into five classes，namely very low susceptibility，low susceptibility，moderate susceptibility，high susceptibility，and very high susceptibility，and the geohazard susceptibility map was produced.The results show that high susceptibility zones located in moderate high mountains and river valleys with high reliefs，steep slopes，intensive gully and soft rock. |
