| Abstract: | According to the features of landslide hazards, the article proposes a method to assess the hazard of landslides with information acquisition analysis based on GIS. It makes full use of the powerful function of spatial analysis and datum management of GIS. At the same time, the information acquisition is adopted to analysis those data. The result of the assessment is finally showed in graphs, which is a great improvement to the efficiency and accuracy of the landslide hazard assessment. |
