AbstractThis paper tries to assess the hazard of landslide of Wanzhou in Three Gorges Region by using GIS and information value method. Landslides have been located by interpretation of aerial photographs, topographic maps and field surveys, and the data collected and constructed into a spatial database with the help of GIS. Using factors including elevation, slope. gradient, slope aspect, lithology, distance to rivers, distance to roads, building distribution, and the distance to dividing line of Shaximiao Group and Suining Formation, a GIS-based assessment process is built. The model of information value is used to produce a map of slope instability. The results of the analysis were verified using the landslide location data. By the comparison between the result predicted and the actual distribution of landslide, we find the high consistency.
