Abstract :Land evaluation is a necessary process for determining the potential cabilities of the land under different uses and for sustainable soil fertility. Today, many land evaluation models have been developed and using for this purpose. But the availability of models is constantly being investigated by the researcers. In this study, Storie Index insert ignore into journalissuearticles values(SI); and Productivity Index insert ignore into journalissuearticles values(PI); models were compared with NDVI values which are a remote sensing analysis in Konya Beşgözler agricultural field using GIS. In the results of the study, SI land evaluation model was determined with higher accuracy coefficient insert ignore into journalissuearticles values(r2: 0.86); compared to PI model insert ignore into journalissuearticles values(r2: 0.29); in terms of the ability of the soil cability based on the density of vegetation and the use of this model is recommended for Arid region soils.
