land use optimization for soil erosion minimization and pure income maximization in the part of taleghan watershed

چکیده
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.

The Effect of Land use and Soil Erosion on Soil Organic Carbon and Nitrogen Stock
Soil organic carbon (SOC) is a principal component in soil quality assessment. Knowledge of SOC and total nitrogen (TN) stocks are important keys to understand the role of SOC in the global carbon cycle and, as a result, in the mitigation of global greenhouse effects. SOC and TN stocks are functions of the SOC concentration and the bulk density of the soil that are prone to changes, influe...
