چکیده

از مناطقی که نیاز به پایش مداوم دارند، مناطق تحت حفاظت می‌باشند که ضرورت ارزیابی اثرات محیط‌زیستی توسعه در این مناطق را الزامی می‌دارد. برای برنامه‌ریزی راهبردی و ارزیابی اثرات ‌محیط‌زیستی توسعه در منطقه شکار ممنوع الوند از مدل‌های تخریب ‌محیط‌زیست و SWOT-ANP استفاده شد. ابتدا آسیب‌پذیری بوم‌شناختی در هر یک از واحد‌های شبکه، محاسبه و طبقه‌بندی شد. سپس با استفاده از نقشه‌های توپوگرافی، مشاهده‌های میدانی، نظر کارشناسان و جوامع محلی، 13 واحد تخریب در کل منطقه شناسایی و شدت آن‌ها تعیین گردید. در نهایت با استفاده از ضرایب تخریب به دست آمده، منطقه به 3 پهنهء، نیازمند اقدامات حفاظتی (01/56 درصد)، نیازمند بازسازی (41/35 درصد) و مستعد توسعه (49/8 درصد) طبقه بندی گردید. با وجود مناطق مستعد توسعه درجه 1، بر اساس شرایط محلی و در نظر گرفتن مسایل اجتماعی- اقتصادی، امکان توسعه بیشتر در منطقه وجود ندارد. در ادامه جهت برنامه‌ریزی راهبردی، نقاط قوت، ضعف، فرصت‌ها و تهدیدها شناسایی شد و با توجه به نظر کارشناسان هر یک وزن‌دهی (ANP) و مورد مقایسه قرار گرفتند. نتایج وزن‌دهی نشان داد که عوامل داخلی با امتیاز 631/0 به عنوان عامل اصلی ارایه راهبردهای حفاظتی در منطقه، و راهبرد تهاجمی-رقابتی با بیشترین امتیاز (340/0)، به عنوان راهبرد بهینه انتخاب گردید. علاوه بر این نقاط قوت موجود برای حفاظت در منطقه بیشتر از نقاط ضعف و نقاط فرصت نیز بیشتر از نقاط تهدید می‌باشد و با ارایه راهبردهای بهینه می‌توان به بهبود در وضعیت حفاظتی منطقه و ارتقاء مدیریتی آن کمک نمود.

چکیده [English]

Areas that need continuous monitoring, are protected areas which necessitates the need for ‎environmental impact assesment of development in these areas. For strategic planning and ‎environmental impact assessment of development in the Alvand no-hunting area, the environmental ‎degradation and SWOT-ANP models were used. First, ecological vulnerability in each of ‎the network units was calculated and classified and then using topographic maps, field observations, ‎experts' opinions, and local communities, 13 degradation units were identified in the whole area and ‎its severity Was determined. Finally, using obtained coefficients of degradation, the area was ‎classified into 3 zones, which need protection measures (56.01%), need reconstruction (35.41%), and ‎development potential (8.49%). Despite the potential for grade 1 development, based on local ‎conditions and socio-economic issues, there is no possibility of further development in the area. ‎Then, for strategic planning in the area, strengths, weaknesses, opportunities, and threats were ‎identified, and then according to opinion of experts, each weighting (ANP) and were compared. ‎The weighting results indicated that internal factors with a total score of 0.631 were selected as ‎main factor in providing protection strategies in the area, and an Aggressive strategy with the ‎highest score (0.340) in the area was selected as optimal strategy. In addition, existing ‎strengths for protection in the area are more than weaknesses, and also opportunities are more than ‎threats, and providing optimal strategies can help improve the protection situation of the area and ‎improve its management. ‎
