چکیده

کلزا یکی از مهمترین دانه های روغنی در دنیا و ایران بوده و در استان سیستان و بلوچستان نیز یکی از محصولات مهم روغنی تلقی می شود. تعیین مناطق مناسب با در نظر گرفتن نیاز های محیطی، بهترین روش درتولید بهینه و کاهش اثرات منفی مدیریت منابع آبی و حفظ منابع طبیعی محسوب می شود. همچنین باتوجه به نوسان های مختلف در تولید این گیاه در سال های مختلف، شناسایی مناطق مستعد و غیر مستعد بر اساس شناخت مزیت ها و محدودیت های محیطی کشت آنها می تواند کمک شایانی به پایداری میزان تولید کلزا در استان داشته باشد. در این پژوهش با استفاده از سامانه اطلاعات جغرافیایی (GIS) لایه های اطلاعاتی مورد نیاز  شامل دمای مطلوب، دمای کمینه، دمای بیشینه، بارش، شیب، ارتفاع از سطح دریا، ماده آلی، شوری خاک، بافت خاک،pH و میزان عناصر غذایی در خاک شامل نیتروژن، فسفر، پتاسیم، کلسیم، آهن و روی در محیط  ArcMapتهیه گردید. بعد از تهیه این لایه ها، کار طبقه بندی و رتبه بندی هر لایه براساس روش محدودیت ساده و جدول نیازهای محیطی کلزا در چهار طبقه بسیار مناسب( بسیار مستعد)مناسب (مستعد) متوسط، نامناسب (غیر مستعد)صورت گرفت. در این پژوهش با هدف بهره گیری از توابع تحلیل های مکانی همراه با فرایند سلسله مراتبی (AHP)جهت شناسایی مناطق مناسب کشت کلزا در شمال و مرکز استان انجام شد و نتایج حاصل نشان داد که مناطق مناسب بیشتر در نواحی کوهستانی و مشرف به دشت های منطقه نیمروز و زاهدان می باشد.

چکیده [English]

         Rapeseed is one of the most important oilseeds In the world and Iran. Considering the strategic importance of rapeseed, especially in Sistan and Baluchestan province, determining the appropriate areas according to the environmental needs, optimal production and reducing the negative effects of water resources management and conservation of natural resources is needed. Also, due to different fluctuations in production of canola in different years, identification of susceptible and non-susceptible areas based on the recognition of their environmental advantages and restrictions can greatly help the stability of the production in the province. In this research, using the GIS, the required information layers including optimal temperature, minimum temperature, maximum temperature, precipitation, slope, altitude, organic matter, soil salinity, soil texture, pH and nutrient content as nitrogen, phosphorus, potassium, calcium, iron, and zinc in an ArcMap environment were produced. After preparing these layers, the classifying and ranking each layer was carried out  based on a simple constraint and the environmental requirements table of rapeseed in four reasonable (very prestigious) moderate, inappropriate (non-susceptible) categories. In this study, the aim of using the spatial analysis functions along with the hierarchical process (AHP) was to identify suitable areas for rapeseed cultivation in the north and center of the province. The results of this study showed that the suitable zone is located more in mountainous and Overlooking the plains of Nimroz and Zahedan.
