摘要

Proper and organized use of natural resources can help preserve this valuable asset. Land use optimization science can be especially useful in this regard. The main purpose of the study is to present an appropriate model for optimized allocation of lands with the purpose of gaining the maximum benefit and minimizing soil erosion in Jajrood watershed. This watershed is located in the southeast of the province of Tehran, Iran. To determine the best land use combination, first the net profit amount in every land use was calculated and then soil erosion was determined in every land use. Finally, the multi-objective linear programming model was used to solve the optimization problem based on simplex method. The optimization results showed hat the area of irrigated farming lands and rangelands should be reduced and orchards should be increased. The results also indicate that after optimization was employed, profitability increased up to 70.9% and soil erosion decreased 36.15%. The results of sensitivity analysis show that the increase in the minimum area of rangelands and the decrease in the maximum summation area of orchard and irrigated farming contributed to a reduction in profit. In addition to these results, the study shows that increasing the area of rangelands and irrigated lands can drastically increase soil erosion, which is due to the high erosion rate of these two kinds of land use.
