چکیده مقاله :
زمینهوهدف:شبکه جاد ه های جنگلی در طرح های جنگلداری، به عنوان تأسیسات زیربنایی در مدیریت، حفاظت و احیای جنگل ها نقش اساسی دارد. تحقیق حاضر جهت بررسی کارایی تکنیک GIS و AHP در تهیه نقشه اراضی مناسب جهت مسیر یابی جاده جنگلی در سری دلاکخیل اداره کل منابع طبیعی شهرستان ساری با مساحتی معادل 1657هکتار صورت گرفت. روشبررسی:در این تحقیق جهت یافتن روشی مناسب برای مسیریابی بهینه جاده های جنگلی و یافتن واریانتی بهینه از نظر زیست محیطی از سیستم اطلاعات جغرافیایی و تکنیک تحلیل سلسله مراتبی استفاده گردید. از اینرو نخست پرسشنامه ای جهت تعیین و اولویت بندی عوامل مؤثر در طراحی جاده یعنی شیب، جهت، تیپ خاک، زمین شناسی، موجودی در هکتار درختان، وضعیت آبراهه، گونه های حفاظتی و چشم انداز تنظیم و سپس نقطه نظرات متخصصان طراحی مسیر جاده جنگلی در مورد تعیین اهمیت نسبی عوامل جمع آوری و با استفاده از تکنیک تحلیل سلسله مراتبی در نرم افزار Expert Choise، به روش مقایسه دو به دو، وزن دهی شدند. سپس بر اساس وزن مشخصه ها، نقشه های عوامل فوق با هم تلفیق شده و نقشه قابلیت عبور اراضی در چهار طبقه با عناوین توان بسیار نامناسب، نامناسب، مناسب و بسیار مناسب تهیه شد. سپس طراحی جاده بر روی نقشه قابلیت عبور اراضی و با استفاده از روش گام پرگار در نرم افزار Arc GIS9.3 انجام پذیرفت. در نهایت مشخصات شبکه جاده های طراحی شده با شبکه جادۀ موجود با روش های باکموند، درصد پوشش و نزدیک ترین مسیر برای انتخاب مناسبترین واریانت مقایسه گردید. یافته ها: تجزیه و تحلیل عوامل موثر در طراحی جاده بر اساس نظر متخصصین طراحی و ساخت جاده های جنگلی، نشان داد که معیار شیب با وزن نسبی 254/0 دارای بیشترین امتیاز و چشم انداز با وزن نسبی 052/0 دارای کمترین امتیاز می باشند. بحثونتیجهگیری: نتایج مقایسه شبکه موجود با پنج واریانت جدید از نظر زیست محیطی نشان داد که واریانت دوم بهترین عملکرد را از نظر عبور از مناطق بسیار مناسب (07/19 درصد) و نامناسب (21/5 درصد) نسبت به جاده موجود با عبور 40/6 درصدی از مناطق بسیار مناسب و 97/35 درصدی از مناطق نامناسب داشت. واریانت دوم با 62/72 درصد پوشش در قیاس با سایر واریانتها و جاده موجود عملکرد مناسب و قابل قبولی از نظر زیست محیطی داشت و در کلیه موارد مورد بررسی به عنوان واریانت بهتر انتخاب گردید. نتایج آزمون مقایسه بین مناسب ترین واریانت و شبکه جاده موجود با استفاده از آزمون مربع کای نشان داد که در سطح 95 درصد این دو شبکه دارای تفاوت معنی داری می باشند (018/0=p).
Background and Objective: Forest roads network in forestry plans have main and basic role in the forest management, conservation and recovery. In this research the ability of GIS and AHP in production of road-use map in Dallak kheil forest of Sari with an area of 1521.89 hectare (without villages in study area) was investigated. Method: In this study, for finding a suitable method for optimal routing forest roads and finding environmentally optimal variant of GIS and AHP technique was used. According to effective factors on road planning such as slope, slop direction, soil, geology, stock growth per hectare, hydrology, landscape and conserved species, a questionnaire was provided and then the idea of the experts about forest road planning and relative importance of factors was collected. The factors were weighted in Expert choice (EC) software via pair wise method.Then based on weights, the maps of mentioned factors were overlaid and land capability map with four classes of most unsuitable, unsuitable, suitable and most suitable was produced. Different variants of forest road were designed on land capability map using Arc GIS 9.3 software and divider method. Finally, the status of designed road network and existing road was compared using Backmund and nearest route method. Findings: Analysis of effective factors in the design based on the road design profesionals and forest roads, showed that standard slope with 0.254 relative weight, have the highest points and the outlook with relative weight 0.052 has the lowest points. Discussion and Conclusions:The result of the comparsion betwwen the existing network with five new variants in terms of environmental considerations indicated that the second variant is the best variant due to the passing of the most sutibel areas (19.7%) and unsutibel (21.5%) in compared to the existing road and other variants. Also The second variant whit 62/72 cover persentage in compared to other variants and existing roads in terms of environmental performance were selected as variants better. The Chi square test was used to compare the most suitable variant with existing road. Results showed that the designed road network was significantly better than that of existing road, regarding pass from suitable area.
