چکیده

از تأثیرات مخرب تغییر کاربری اراضی یک حوضه، افزایش تولید رسوب و ورود آن به رودخانه‏ها و تجمع آن در مخزن سدها‌ست. از این‌رو، بررسی تأثیر تغییر کاربری اراضی بر فرایندهای هیدرولوژی امری مهم و ضروری است. این پژوهش با هدف بررسی اثر تغییرات کاربری اراضی بر رسوب معلق طی سال‏های 1994 تا 2010 در حوضۀ آبخیز دینور در استان کرمانشاه با استفاده از مدل SWAT صورت گرفت. واسنجی و اعتبارسنجی مدل با استفاده از برنامۀ SUFI-2 انجام شد. نتایج شاخص‏های آماری ‌استفاده‌شده در ارزیابی مدل مد نظر در مرحلۀ واسنجی و اعتبارسنجی NS و R2 به‌ترتیب بیش از 50 و 60 درصد به‌دست آمد که دلالت بر کارایی مدل در شبیه‌سازی داده‌های هیدرولوژیکی در حوضۀ مطالعه‌شده است. بررسی کاربری اراضی طی یک دورۀ 16 ساله نشان داد بیشترین تغییر مختص‌به کاربری کشاورزی است با افزایشی بیش از 30 درصد و کمترین تغییر در کاربری مناطق مسکونی و جاده 25/3 درصد رخ داده است. همچنین نتایج به‏دست‌آمده از بررسی رسوب معلق، گویای تأثیر چشمگیر رسوب تولیدشده از تغییرات کاربری اراضی در دورۀ مطالعه‌شده است. طوری که بیشترین میزان رسوب در سال 1994، 18/1 گرم در لیتر بوده، اما این میزان در سال 2010 به 65/12 ‏گرم در لیتر رسیده است.

چکیده [English]

The devastating impact of land use change in the watershed is increasing the generation rate of sediment and entrance to rivers and sedimentation in reservoirs. According to this, studying on impact of land use change on hydrological process is necessary. Aim of this study was investigating the impact of land use change on suspended sediment during 1994 to 2010 by SWAT model in Dinevar watershed. SUFI-2 program was used for SWAT calibration and validation. The results of NS and R2 indicators above of 50 and 60 percent for both calibration and validation steps respectively imply to the model efficiency to hydrology data simulating in Dinevar watershed. The analysis of land use over a period of 16 years showed that the greatest change was for agricultural land more than 30 percent and the minimum was occurred for residential area and roads (3.25%). The results of the suspended sediment study showed the significant effect of land use change on sediment generated in the study period. So that the maximum amount of suspended sediment in 1994, 18.1 grams per liter, but this amount in 2010 reached to 65/12 gram per liter.
