| چکیده | ||
| بهینهسازی کاربری اراضی یکی از راهکارهای مناسب برای حفاظت خاک است. از این رو، تحقیق حاضر با هدف بهینهسازی کاربری اراضی به منظور کمینه‌‌کردن فرسایش و بیشینهسازی سود در حوضة آبخیز طالقان با مساحت 23/80427 هکتار انجام شد. بدین منظور، با محاسبة مساحت، میزان فرسایش، و درآمد خالص هر یک از کاربریهای اراضی حوضة آبخیز مورد تحقیق، با توجه به استانداردهای مورد نیاز هر یک از کاربریهای اراضی، سطح هر یک از کاربریها استخراج و با تعیین محدودیتها و دو تابع هدف با استفاده از نرمافزار ADBASE بهینهسازی شد. نتایج تحقیق حاضر نشان میدهد میزان فرسایش از 28/6 تن در هکتار در سال به 84/5 تن در هکتار در سال (99/6 درصد) و میزان سود از 38/118174 به 02/112681 میلیون ریال (65/4 درصد) پس از بهینهسازی کاربری اراضی کاهش یافته است. همچنین، بر اساس نتایج، پیشنهاد می‌شود اراضی با کاربری دیم به اراضی با کاربری زراعت آبی و باغ و مرتع تبدیل شود. | ||

| چکیده [English] | ||
| 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. | ||
