چکیده مقاله :
زمینه و هدف: منطقه حفاظت شده ارسباران در شمالغرب ایران و در استان آذربایجان شرقی واقع شده است. این منطقه جزء یکی از نه ذخیره گاه زیست کره کشور می باشد و 66.5 درصد از سطح این منطقه را جنگل پوشانده است. در این پژوهش به ارزیابی توان جنگلداری این منطقه با استفاده از سیستم اطلاعات جغرافیایی(GIS) پرداخته شد. روش بررسی: در این تحقیق از دو روش بولین و تکنیک ترکیب خطی وزنی و وزن دهی به روش سلسله مراتبی بر پایه AHP جهت ارزیابی توان اکولوژیک جنگل های منطقه حفاظت شده ارسباران استفاده شده است. جهت ارزیابی توان جنگلداری منطقه مورد مطالعه، ابتدا به مطالعه و شناخت ویژگی های اکولوژیکی منطقه از قبیل ارتفاع از سطح دریا، شیب، بافت خاک، اقلیم، ارزش گونه های گیاهی، عمق خاک و تراکم تاج پوشش پرداخته شد و سپس مدل اختصاصی جنگلداری ارسباران تهیه گردید. یافتهها: در مرحله اول این تحقیق، توان جنگلداری منطقه در نرم فزار ARC GIS10 بر اساس منطق بولین مشخص گردید که نتایج حاکی از وجود طبقات 3 تا 7 وعدم وجود طبقات 1 و 2 جنگلداری بود. در مرحله دوم این تحقیق، با استفاده از نظر کارشناسان سلسله مراتب اهمیت معیارها و زیر معیارهای دخیل در فرایند ارزیابی مشخص و با استفاده از نرم افزارExpert Choice11 وزن هر کدام از فاکتورها مشخص گردید. سپس روش ترکیب خطی وزنی برای کاربری جنگلداری برای منطقه مذکوراجرا شد که نتایج حاکی از وجود هر 7 طبقه جنگلداری برای منطقه مورد تحقیق بوده است. بحث و نتیجهگیری: برای ارزیابی توان اکولوژیکی سرزمین به منظور توسعه انواع کاربریها، سالهاست که از روش سیستمی ابداعی مکهارگ استفاده می شود. اقدام جدیدتر در این فرآیند، استفاده از مدلهای ریاضی در ارزیابی توان اکولوژیکی و به کارگیری فرآیند تحلیل سلسله مراتبی (AHP) در تعیین وزن و اهمیت نسبی گزینهها و ارزیابی توان اکولوژیکی با سامانه اطلاعات جغرافیایی (GIS) است. در این تحقیق ارزیابی توان اکولوژیکی جنگلداری با دو روش فوق الذکر انجام، و طی آن معایب و مزایای آنها بررسی گردید.
Background and Objective: Arasbaran protected area is located in East Azerbayjan in the northwest of Iran. This area is one of the nine reserves in Iran, and 66.5% of it is covered by forests. In this study, land capability evaluation of this area for forestry was carried out in Geographic Information System (GIS) surrounding. Method: Both Boolean and weighted Linear Combination (WLC) methods along with analytical Hierarchy Process (AHP) were used. First, the ecological characteristics of the study area including elevation, slope, soil texture, climate, value of vegetation type, soil depth and vegetation density were studied and then the calibrated model for forestry in Arasbaran area was created. Findings: In the first step, land capability assessment was done using Boolean method and results showed the presence of class capabilities of third, fourth, fifth, sixth and seventh, and lack of class capability of first and second for forestry. In the next step, the importance of criteria and sub-criteria was calculated using expert’s comments and AHP technique in Expert Choice 11. Then, land capability assessment was done using weighted linear combination. The results showed that all of the seven suitability classes for forestry were proper in the area. Discussion and Conclusion: Mc-Harg systemic model has been used to evaluate the ecologic capability evaluation for many years. The new process in ecologic capability evaluation is to use the mathematical models and to use the analytical hierarchy process for determining the weights and relative importance of the alternatives and for ecologic capability assessment by geographic information systems (GIS). In this study, to evaluate the forestry ecologic capability, both Boolean and WLC methods were used and the advantages and disadvantages of them were investigated.
