Abstract: 
Landslide is one of the mass movement processes that occur in Iran and parts of the world every year. It causes huge human loss and economical damages. This research investigates the evaluation of fuzzy logic operators in prediction of landslide potential. Thus, Shirood Watershed was considered as a suitable model for north of Iran. First, investigating resources, some of the most important factors in landslide occurrence such as slope, litho logy, land use, aspect and distance from fault in G.I.S. environment were prepared and digitized as independent variables. Landslide distribution information layer was prepared with use of interpretation of air photos and field survey with use of G.P.S. variables. The classification was done with histogram trend changes and available classifications. Weighting variables classes were determined between 0-1, and then weighted maps classified with fuzzy operators. Obtained maps accuracy was evaluated with use of quality sum index (Qs)' Results showed the fuzzy Gamma 0.8 operator is one of the best suitable operator for land slide potential in Shirood Watershed.
