| چکیده | ||
| هدف از پژوهش پیش‌رو، ارزیابی اقتصادی گزینه‌های فعلی استفاده از جنگل (دامداری و برداشت چوب) بود. منطقه مورد مطالعه سری 11 شفارود به مساحت 2200 هکتار واقع در استان گیلان بود. از داده‌های قیمت چوب سرپا، رویش سالانه و نرخ سود بانکی برای تعیین ارزش خالص فعلی برداشت چوب استفاده شد. همچنین قیمت و هزینههای دام (میش) و نرخ سود بانکی برای تعیین ارزش خالص فعلی دامداری استفاده شد. پس از ارزیابی اقتصادی، مجموع ارزش خالص فعلی به‌دست‌آمده از برداشت چوب (بالفعل) و دامداری برابر با 30405809 ریال در هکتار محاسبه شد. از مجموع ارزش خالص فعلی، سهم جنگل‌داری 92/7 درصد و سهم دامداری 7/3 درصد بود. به‌عبارت دیگر، ارزش خالص فعلی دامداری حدود 12/7 برابر کمتر از جنگل‌داری بود. نتایج به‌دست‌آمده از پژوهش پیش‌رو نشان داد که این بخش از جنگل با توجه به عملکردهای فعلی، قابلیت مدیریت برای تولید چوب را داشته است. برای مدیریت جنگل بر پایه اصول پایداری و تأمین نیازهای جنگل‌نشینان، باید مدیریت جنگل را به سمت جنگل‌داری اجتماعی سوق داد. | ||

| The aim of this research is to evaluate current uses of forest (animal husbandry and wood harvesting) in district no. 11 of Shafaroud forest with an area of 2200 ha in Guilan province. Factors including stumpage price, annual growth rate and rate of interest were used to determine the net present value of timber harvesting. Furthermore, price, animal husbandry costs and rate of interest were applied to determine the net present value of animal husbandry in forest. Economic analysis revealed the net present value of 30105809 IRR per hectare gained by wood harvesting and animal husbandry in forest, with 92.7% and 7.3%, proportions of forestry and animal husbandry, respectively. In other words, net present value of animal husbandry is about 12.7% lower than forestry. The results of this study showed that the present forestry practice in the study area enables the timber production management. In order to manage the forest based on sustainability and meet the forest dwellers needs, forest management is suggested to be planned toward the social forestry. | ||
