Appropriate utilization of agricultural land and natural resources, decreased erosion and increased production occurs in watersheds. On the other hand, land use pattern due to increasing human activities on the ground to meet different needs, is changing. Optimization of land use is one of the management methods to achieve stability and reduce soil erosion. In this study, by using linear programming (simplex) and Geographic Information System(GIS), was investigated the land use optimization in three scenario option to: current condition, management condition, and standard condition.Erosion potential by using MPSIAC Model in irrigated land 1.65, dry lands 3.31, pasture 3.64, gardens 1.49 and 3.85 tons per hectare per year was estimated for Chehel-Gazi basin. The results of the sensitivity analysis for tree scenario showed that in the event optimize land use, erosion potential in the current Condition 0.85 percent increased, But in the land management Condition 16.92 percent and in a standard Condition 32 percent decreased. The results of sensitivity analysis showed that changes in the area of pasture all three options have the greatest impact in changing erosion potential of basin.
