Land use optimization is one of the suitable methods for soil conservation. The present research with objective of land use optimization for soil erosion minimization and pure income maximization was conducted in the part of Taleghan Watershed which comprises 80427.23 ha in area. To achieve this propose, area, erosion rate and net income value of each land uses according to requiring standards of each land uses area was extracted. Then, limitations and two objective functions were determined and optimization problem was solved by using ADBASE software. The results revealed that the optimization decrease 6.99 percent of erosion rate(6.28 ton/ha/year to 5.84 ton/ha/year) and 4.65 percent of pure income(118174.38 to 112681.02 million Rials). Also, the results proposed that drylands farming are changed to garden and orchard and rangelands.
