Identify factors in the development of gully erosion and its susceptibility to the major management tools and control this phenomenon and Suitable Select options to deal with the spread of this phenomenon. Hence, The aim of this study was to select the most influential factors in gully erosion hazard using two methods of AHP and ANP, specifying the type of controls that are located within areas with high and very high sensitivity and Finally compare the performance of two models in assessing the development of gully erosion in the basin Kahor plains of the fars province. In this regard, a number of important factors affecting the development of gully erosion were digitized in GIS environment and preparation. Then gully area map using aerial photographs of the year 1372 was prepared. The zoning maps on gully erosion model (AHP) and (ANP) were prepared. The results show that the studied factors, lithology and slope factor as the most important factor, and land use as a second factor of importance is known. In any case, both are 100% Gullies basin occurred in areas with very high sensitivity and high. Particularly on agricultural land and barren land has occurred. The results show a slight performance difference between both models is ideal for zoning gully erosion Based on field observations and logic output is supplied to the researchers
