چکیده مقاله :
امروزه بسیاری از کشورها در پی یافتن راهی برای مدیریت پایدار جنگل هایشان هستند. جهت دستیابی به این مهم نیاز است منابع جنگلی موجود از نظر معیارهای پایداری مورد مطالعه قرار گیرند. مقایسه ی سه ذخیره گاه جنگلی شهرستان سمیرم با توجه به معیارهای پایداری و اولویت بندی این ذخیره گاه ها، رسیدن به مدیریت پایدار این منابع را سهل تر می سازد. جهت مقایسه ی این ذخیره گاه های جنگلی هشت معیار وسعت، تنوع زیستی، سلامتی و زنده مانی، نقش های تولیدی، فرسایش، مسائل اقتصادی– اجتماعی، چارچوب های قانونی، خط مشی های تشکیلاتی و کیفیت در نظر گرفته شد که این معیارها به طور کلی 19 زیر معیار را شامل می شوند، لذا به علت پیچیدگی مسأله از تکنیک تصمیم گیری چند معیاره (AHP) استفاده شده است. سلسله مراتبی در 4 سطح هدف، معیارها، زیر معیارها و گزینه ها تشکیل شد. برخی از معیارها و به تبع آن برخی از زیر معیارها کیفی بودند که جهت دستیابی به نتایج منطقی و جامع، از همکاری و تشریک مساعی گروهی از متخصصین استفاده شد. نتایج حاصل از قضاوت متخصصین، معیار مسائل اقتصادی - اجتماعی را نسبت به سایر معیارها در اولویت نشان داد. همچنین نتایج نهایی تحلیل سلسله مراتبی گویای ارجحیت ذخیره گاه جنگلی چالقفا از لحاظ معیارهای پایداری منابع جنگلی نسبت به ذخیره گاه های جنگلی داغباشی و تنگ خشک بود. با توجه به نتیجه ای که حاصل شد پیشنهاد می شود ذخیره گاه جنگلی چالقفا به عنوان الگو مد نظر قرار گیرد و معیار هایی که دستخوش تغییر انسان می شوند، برای سایر منابع جنگلی و یا ذخایر جنگلی شهرستان، مطابق با این ذخیره گاه تغییر داده شود که این خود باعث مدیریت پایدار جنگل می شود.
Nowadays, many countries and governments are finding alternatives for sustainable management for theirs forest resources. It is a must to consider available forest resource in point of permanent criteria, in order to get this important issue. For comparison of forest reserves(Chalghafa, Daghbashi and Tang Khoshk) of Semirom,Esfahan province, obtaining the resource of sustainable management make more easier. According to permanent standards and resource sites priority for comprising of this forest reserves 8 criteria to be considered such as extent ,biodiversity, health and survival, product roles, erosion, socio – economical issues, legal criterion, organizational guideline and quality. These criteria are included overall 19 sub criteria. So Multi-Criteria Decision Making Methods (MCDMM) has used because of problem complexity. The hierarchical formed in the 4 levels that is purpose, criteria, sub criteria and options. Some of the criteria and as a result some sub criteria were qualitative. For accessing integrated and logical results, we benefit specialist cooperation . The results showed that socio – economical problem are more important than the other criteria in priority. Also, final results of Analytical Hierarchy Process (AHP) indicated that Chalghafa forest reserve in respect of sustainable forest management is in a higher situation than Daghbashi and Tang Khoshk forest reserves. According to obtained results, it is suggested that Chalghafa forest reserve site would be considered as a symbol area. Other yard sticks that to be exposed by human, we should change other forest resources or city’s forest reserves corresponding to this resource sites so it causes to sustainable forest management.
