چکیده

میزان خردی و پراکندگی اراضی کشاورزی بیانگر سطح مشکل‏دار بودن ساختار مدیریت بهره‏ برداری از زمین هست که می‏تواند توسعه کشاورزی را محدود نموده و فرصت‏ های توسعه پایدار روستایی را کاهش دهد. بنابراین هدف این تحقیق استخراج متغیرهای خردی و پراکندگی اراضی کشاورزی و تدوین شاخص‏ های مربوطه جهت سنجش میزان آن در استان آذربایجان شرقی است. جامعه آماری این تحقیق را بهره‌برداران کشاورزی ساکن در استان آذربایجان شرقی تشکیل می‌دهد (212926=N). حجم نمونه با استفاده از فرمول کوکران 380 نفر برآورد شد که به روش نمونه‌گیری طبقه‌ای و به صورت تصادفی انتخاب شدند. ابزار جمع‏آوری اطلاعات پرسشنامه‏ ای بود که روایی آن با استفاده از نظرات پژوهشگران و کارشناسان سازمان امور اراضی کشور بازبینی و اصلاح شد. اطلاعات مکانی اراضی کشاورزی با استفاده از بانک اطلاعات کاداستر اداره امور اراضی استان آذربایجان شرقی تهیه و تحلیل شد. نتایج تحقیق نشان داد که شهرستان‏های بناب و بستان‏آباد با متوسط اراضی 28/2 و 71/13 هکتار به ترتیب خردترین و وسیع‏ترین اراضی را داشتند. از نظر پراکندگی نیز قطعات شهرستان بناب و اسکو با میانگین فاصله 8/3 و 4/1 کیلومتر از همدیگر و از مرکز روستا به ترتیب دارای بیشترین و کمترین میزان پراکندگی بودند. از نظر میزان خردی و پراکندگی اراضی نیز که از طریق شاخص شموک به دست آمد شهرستان‏های شبستر و بستان‏آباد با میزان 3/8 و 3/1 کیلومتر بر هکتار به ترتیب دارای بیشترین و کمترین میزان خردی و پراکندگی اراضی کشاورزی بودند.

چکیده [English]

The rate of land fragmentation refers to a problem in land management that can limit agricultural development and reduce the opportunities for sustainable rural development. The purpose of this research was to identify land fragmentation and dispersion variables and to develop indices to measure those variables. The statistical population of the research consisted of agricultural land holders in East Azarbaijan province (N = 212926). A sample size of 380 people was determined by using Cochran's formula. They were selected by stratified random sampling. The data gathering tool was a questionnaire whose validity was examined by using the comments of the researchers and the experts at the Land Affairs Organization. Some local information about the land was obtained and analyzed by using the cadastre database of Land Administration of East Azarbaijan province. The results showed that Bonab and Bostan Abad counties, with the average land area of 2.28 and 13.71 hectares respectively, have the smallest and the largest pieces of land. In terms of dispersion, the lands in Bonab and Oscou counties, with the average distance of 3.8 and 1.4 kilometers from each other and from the village center, had the highest and the lowest rate of dispersion respectively. In terms of land fragmentation and dispersion rates, obtained through the chemok index, Shabestar and Bostan Abad counties, with the rate of 3.8 and 1.3 km / ha, had the most and the least fragmented and dispersed agricultural lands respectively.
