Abstract
The paper considers the outcome of multi-criteria analysis of landslide susceptibility on the NW outskirts of Fruška Gora Mountain, Serbia. The area of the interest is known for landslide occurrences, and to focus on the most affected areas, it was necessary to consider some principal factors (lithology, slope inclination, rainfall, erosion, vegetation, altitude and slope aspect) and sort them by their importance to the phenomena. Prior to any criteria assessment, available data records had been assembled and refashioned as raster datasets. Thereafter, the criteria arising from an analytical hierarchy process (AHP) provided their weights of preference in the final model. In addition, the model was analysed for the information gain and classified in accordance to the optimal informativeness. Being tailored in the context of raster modelling, aided by the GIS spatial tools, our result gained substantial correlation to the control reference map (a digital photo-geological interpretation... map of active and potential landslides).

U radu su prikazani rezultati više-kriterijumske analize sklonosti ka pojavi klizipšta na SZ padinama Fruške gore. Područje je inače poznato po pojavama klizišta i u cilju da se naznače najugroženija područja bilo je neophodno razmotriti uticaj najznačajnijih faktora koji utiču na pojavu klizišta (litološke jedinice, nagib padina, količina padavina, uticaj erozije, uticaj vegetacije, visina i ekspozicija padina) i sortirati ih na osnovu značaja njihovog uticaja na proces kliženja. Pre same analize kriterijuma za sortiranje faktora, dostupni podaci su prikupljeni i pripremljeni u formi rasterskih setova podataka. Kriterijum za sortiranje dobijen je pomoću Analytical Hierarchy Process (AHP) analize, koja je dala težinske faktore za svaki od pojedinih faktora, neophodnih za konačni model. Takođe je sam konačni model dodatno ispitan sa stanovišta informativnosti (Information Gain) i klasifikovan u skladu sa optimalnom informativnošću. Konačni model, koji predstavlja rasterski model i koji ...je izveden u GIS okruženju, dao je dobre rezultate, koji su u korelaciji sa postojećim katastrom klizišta (digitalnom foto-geološkom interpretacijom na kojoj su prikazana klizišta sa aktivnim i privremeno umirenim procesom).
