Ranking of Erosion of the Razan Basin with using of the models: Fuzzy logic, EPM and BLM in environment of GIS

Awareness of the amount of the danger of ablation, the possibility of recognizing critical areas and arranging of managing plans and protecting plans achieved. the present study is produced aiming the use of fuzzy logic EPM and BLM in predicting the power of ablation and calculation of the whole illuviation that has been produced in a year in the Razan basin by help of evaluation and GIS then the correctness of the studies have been compared according to the results of BLM model the more of the studied are wan in low erosion in the rest of the paper by using EPM model the whole of illuviation that had been produced in Razan basin was calculated according to the results of EPM model the power of ablation in the studied area laid in the ablation of middle class also the results of game operator of fuzzy %98 of study area was show reel in five class of the less clanger to the most danger final the results of credit evaluating of models showed that the results of EPM model had more similarity with the prepare data of the study that show the correctness of EPM model in analyzing ablation of the studied area according to the ranking of the area and using EPM model 28/44- 32/16 and 39 /40 % Percent of the space of the area laid in the classes of the more less .less – middle.
