چکیده
دانش و آگاهی درزمینه پوشش گیاهی و مرتعداری بهعنوان اولین و مهمترین ابزار شناخت اکوسیستمهای مرتعی، جهت مدیریت صحیح و بهرهبرداری بهینه آبخیزها موردپذیرش همه بخشهای مرتبط با این مقوله است. این تحقیق در بخش بهمئی شهرستان کهگیلویه که جزء مناطق قشلاقی استان کهگیلویه و بویراحمد با وسعت 1068/54 هکتار و باهدف ارائه برنامه مدیریتی مناسب بیولوژیکی احیای حوزه آبخیز با توجه به عوامل طبیعی و شرایط اکولوژیکی منطقه انجام گردید. پس از تلفیق نقشههای پایه در محیط نرمافزار GIS بر اساس خصوصیات فیزیکی و اکولوژیکی واحدهای کاری نقشه عملیات بیولوژیکی تهیه گردید. بوتهکاری، بذرپاشی، قرق، کشت تلفیقی، حفاظت ازجمله برنامههای بیولوژیکی هستند که برای منطقه موردمطالعه مناسب تشخیص دادهشدهاند. نتایج حاصل از مشخصات واحدهای کاری حوضه جهت تصمیمگیری و انتخاب بهترین برنامههای مدیریتی با توجه به ویژگیهای واحدهای کاری با تفکیک مساحت هر برنامه مدیریتی ارائه گردید. همچنین بیشترین مساحت عملیات پیشنهادی با توجه به شرایط حوضه به مدیریت چرا و حفاظت اختصاصیافته است و با توجه به نامساعد بودن شرایط حوزه برای کشاورزی، اراضی زراعی کمترین سهم را ازنظر مساحتی به خود اختصاص دادهاند.

چکیده English
Knowledge about vegetation cover and rangelands is the first and most important means of understanding rangeland ecosystems for proper management and optimal use of watersheds, accepted by all relevant departments in this field. This study was conducted in the Bahmai section of Kohgiluyeh and Boyer-Ahmad Province with an area of 1068.54 hectares to provide a suitable biological management plan for the restoration of the watershed according to the natural factors and ecological conditions of the region. After the integration of basic maps in GIS software, a map of biological operations was prepared based on the physical and ecological characteristics of working units. Planting, seeding, enclosure, intercropping, and conservation are for the study area biological programs that have been found suitable. The results obtained from the specifications of the working units of the basin were presented to decide and choose the best management plans according to the characteristics of the operational units by dividing the area of each management plan. Also, most of the area of the proposed operation is dedicated to grazing management and conservation, and due to the unfavorable conditions of the area for agriculture, agricultural lands have the lowest share in terms of area.
