چکیده

     آب، خاک، پوشش گیاهی و سایر منابع طبیعی، با استفاده علمی و آگاهانه، پایدار و قابل استفاده خواهند بود. در صورت بهره‌برداری بی‌رویه و استفاده نامعقول از این منابع که باعث جلوگیری از تجدید حیات آن‌ها شود، فناپذیر خواهند بود. در مطالعه حاضر، از برنامه‌ریزی آرمانی فازی برای تعیین الگوی بهینه کشت محصولات زراعی شهرستان ارزوئیه با تأکید بر پایداری منابع طبیعی و محیط زیست استفاده شد. به این منظور، چهار آرمان فازی شامل بیشینه کردن سود، کمینه کردن مصرف آب آبیاری، کمینه کردن کود و کمینه کردن سموم در قالب چهار سناریو مد نظر قرار گرفت. اطلاعات مورد نیاز این تحقیق از طریق پرسشنامه و مصاحبه حضوری و همچنین آمارنامه‏های جهاد کشاورزی استان کرمان جمع‏آوری شد. چهار الگوی بهینه کشت در اثر دادن وزن‌های متفاوت به آرمان‏ها بدست آمد. نتایج نشان داد در سناریوهایی که حفظ منابع طبیعی و پایداری تولید در اولویت قرار می‏گیرد، محصولاتی که آب، کود و سم کمتری مصرف می‏کنند بیشتر وارد الگوی کشت می‏شوند. در مقابل در آن سناریو که بیشترین وزن به آرمان بیشینه کردن سود داده شده است، تنها هندوانه و سیب‏زمینی که نسبت به سایر محصولات بالاترین سود در هکتار را دارا هستند وارد الگوی کشت می‏شوند، هرچند که مصرف آب آنها نسبت به محصولات دیگر بالاتر است. بنابراین، لحاظ نمودن رویکرد پایداری منابع طبیعی و محیط زیست در تعیین الگوی بهینه کشت، مؤثر است.

چکیده [English]

Water, soil, Vegetation and other natural resources, will be sustainable and useable permanently when they use scientifically and consciously. If the resources are used irregularly, this action will cause to stop renewing resources and they will be mortal. In current study, we used fuzzy goal programming for determining of optimal cropping pattern which emphasizes sustainability of natural resources and environment. For this purpose, four fuzzy goals include profit maximization; irrigation water minimization, fertilizers minimization and pesticides minimization were considered in four scenarios. Requirement data were collected by questionnaire and from Kerman province Jihad Keshavarzi documents. Four optimal cropping patterns were represented by considering different weights for goals. Results illustrated in those scenarios that natural resource conservation and production sustainability have priority, the activities that need require less water, fertilizers and pesticides are more into the cropping pattern. On the contrary, in that scenario that profit maximization has the most weight, the cropping pattern limited to watermelon and potato activities. Because have the highest profit in hectare, although use the most water. Therefore, considering natural resources and environmental sustainability approaches are effective on optimal cropping pattern determination.
