Landslide susceptibility mapping in the Damrei Romel area, Cambodia using frequency ratio and logistic regression models

摘要: This study applied, tested and compared a probability model, frequency ratio statistical logistic regression to Damre Romel area, Cambodia, using geographic information system. For landslide susceptibility mapping, locations were identified in the area from interpretation of aerial photographs field surveys, spatial database was constructed topographic maps, geology land cover. The factors that influence occurrence, such as slope, aspect, curvature distance drainage calculated database. Lithology lineament extracted Land cover classified Landsat TM satellite imagery. relationship between landslides models. relationships, coefficient overlaid make map. Then map with known tested. As result, model (86.97%) (86.37%) had high similar prediction accuracy. can be used reduce hazards associated planning.
