چکیده

اهمیت و ضرورت برنامه‌ریزی منطقه‌ای کشت را می‌توان ناشی از لزوم استفاده بهینه از ظرفیت های تولید منطقه‌ای و ارائه راهکارهایی جهت نیل به توازن عرضه و تقاضا در تصمیم گیری‌ها و تخصیص منابع تولید کشاورزی دانست. مطالعه حاضر به معرفی الگوی فراگیر برنامه‌ریزی منطقه‌ای کشت محصولات کشاورزی پرداخته که یکی از زیر مجموعه‌های رویکرد برنامه‌ریزی ساختاری چند هدفه (MOSP) بوده و اهداف متفاوتی همچون اهداف اقتصادی، اجتماعی و زیست محیطی به صورت مجزا و توأم مورد توجه قرار گرفته است. محدوده مطالعاتی عبارت از اراضی قابل کشت زراعی و باغی در محدوده تقسیمات سیاسی-جغرافیائی 23 شهرستان واقع در استان اصفهان در سال 1393 بود. نتایج نشان داد که در گروه‌های اصلی غلات و علوفه کاهش محسوسی در سطح زیرکشت بهینه مدل چند هدفه به ترتیب به میزان 32 و 58 درصد رخ داده است. افزایش سطح زیرکشت گروه محصولات باغی به میزان 38 درصد در الگوی بهینه مدل چند هدفه از دیگر موارد مهم در تحلیل نتایج بود. در مجموع جهت نیل به اهداف اقتصادی، اجتماعی و زیست محیطی ذکر شده در این مطالعه در قالب یک برنامه‌ریزی چند هدفه کاهش 37 درصدی سطح زیرکشت در استان اصفهان اجتناب ناپذیر است. دست آوردهای این اقدام کاهش مصرف آب آبیاری به میزان 10 درصد، افزایش سود ناخالص به میزان 24 درصد و افزایش تولید به میزان 10 درصد می‌باشد. با توجه به اینکه در طرح برنامه‌ریزی ساختاری الگوی کشت اهدافی متفاوت و گاهاً متضاد مورد نظر بوده و ایجاد مصالحه بین اهداف مورد نظر در مدل برنامه‌ریزی ساختاری چند هدفه امکان پذیر است، لذا استفاده از آن برای تصمیم‌گیرندگان توصیه می‌شود.
