Tóm tắt

More than 70% of the areas of Quang Nam province are mountainousterrain with heavy and seasonal rainfall. In recent years, economic activities and thework of humans have increased dramatically, destroying vegetation cover, andcausing the natural environment to change significantly, which promotes theoccurrences, development, and increase of landslides. This research uses thestatistical index to determine the weight of each class in each factor and an analyticalhierarchical process (AHP) to determine the weight of factors. A landslidesusceptibility assessment map was established by integrating the factor maps. Theresult showed that landslide susceptibility in Quang Nam was categorized as 28.53%for low and very low; 39.66% for moderate, and 31.82% for high and very high.ep-2
