| تغییر پوشش گیاهی یکی از عامل‌های مهم در تغییر کمی و کیفی جریان آب‌شناسی است. در این تحقیق با مدل ارزیابی اثر آبشناختی بلندمدت اثر حالت‌های ممکن مدیریت پوشش گیاهی بر حجم روانآب سالانه و آلاینده های آب آبخیز حبله رود پیش بینی کرده شد. مدل با نقشه های کاربری و نقشه گروههای آب‌شناسی خاک منطقه اجرا شد. نتیجه‌ی ارزیابی کارآیی مدل نشان دهنده‌ی کارآیی مناسب در تراز 5% است. بی‌قطعیتی مدل با روش بوتاسترپ بررسی شد. کم‌ترین و بیش‌ترین بی‌قطعیتی در فراسنج‌های نیترات، نیتریت و حجم روانآب به‌ترتیب با ضریب تغییر 0/15 و 0/26 بود. به‌جز وضع موجود، فعالیتهای جنگل‌کاری، بذرپاشی، بذرکاری، کپه کاری، قرق مرتع، تاغ کاری، احداث باغ، درختکاری و علوفه کاری نیز ارزیابی کرده شد. نتیجه‌ی تجزیه و تحلیل نشان داد که با اعمال‌کردن بذرپاشی مرتع، حجم روانآب سالانه از 301/07 میلیون مترمکعب برای کاربری فعلی حوزه به 247/92 میلیون مترمکعب کاهش یافته است. کل نیترات، نیتریت و فسفر خروجی به ترتیب از 214/2 و 92/4 تن در شرایط کاربری فعلی به 154/2 و 80/3 تن کاهش یافته است. نتیجه‌ی ارزیابی نشان دهنده‌ی کارآیی مناسب این مدل برای پیش بینی‌کردن اثر حالت‌های ممکن تغییرکاربری در این آبخیز است. اجرای فعالیتهای مدیریتی پوشش گیاهی به کاهش حجم روانآب و کاهش آلاینده های آب در آبخیز حبله رود منجر خواهد شد. | ||

| چکیده [English] | ||
| Land cover change is an important factor in terms of its impacts on altering the quantity and quality of the flow regimes. The Long-term Hydrologic Impact Assessment model was used to predict the impacts of land cover management scenarios on run-off volume and water pollutants on the Hablehrud Basin. Land-use and soil hydrologic group layers were used in running the model. Evaluation of the results indicated a satisfactory performance at the 5% level of significance. Additionally, the model uncertainty analysis was conducted using the bootstrap method. Nitrate, nitrite and run-off volume parameters had the minimum and maximum uncertainty levels with respect to the coefficient of variation at 0.15 and 0.26, respectively. In addition to the current condition, agroforestry, seeding, drill seeding, hill-drop planting, grazing exclusion, haloxylon plantation, orchard stabilization, tree plantation and forage growing actions were evaluated. By applying the seeding scenario, the annual runoff volume would drop from 301.07 million cubic meters per year for the current land use in the watershed to 247.92 million cubic meters per year. Given the seeding scenario, the total amounts of nitrates, nitrite and phosphorus in the watershed would also decrease from 214.17 and 92.4 ton per year for the current land cover to 154.2 and 80.3 ton per year, respectively. Evaluation of the results indicates the satisfactory performance of the model to predict the effects of land-use change scenarios in this area. Implementing the land cover management actions leads to a reduction in the run-off volume as well as the water pollutants on the Hablerud Basin. | ||
