چکیده

در حال حاضر گونه اصلی پرورش ماهیان خاویاری درکشور فیل ماهی Huso huso)) است که بدلیل رشد سریع وامکان تولید بچه ماهی به میزان کافی در مراکز تکثیر ماهیان خاویاری و قیمت بالای گوشت و به خصوص خاویار آن،در اغلب مزارع پرورش ماهیان خاویاری در سطح کشور معرفی شده است.با توجه به نتایج مطلوب کسب شده در دو مرکز تکثیر و پرورش ماهیان خاویاری در سال های اخیر در شمال استان خوزستان ،تحقیق حاضر با هدف انجام مطالعات پایه در جهت استعداد و مکان یابی برای توسعه مراکز تکثیر و پرورش فیل ماهی در استان خوزستان با استفاده از سامانه اطلاعات جغرافیای(GIS) طراحی گردید.
برای استعداد و مکان یابی از چندین شاخص استفاده و با تلفیق دو مدل منطق فازی و(AHP)،ابتدا هر کدام از لایه ها در محیط سیستم اطلاعات جغرافیایی فازی ودر نهایت در(GIS)کلاس تناسب تقسیم بندی شد.براساس نتایج به دست آمده بیشترین وزن به شاخص های اکولوژیکی 0.321 رتبه های بعدی به ترتیب به اقلیم 0.205،اقتصادی واجتماعی 0.179،طبیعی 0.167و موانع و محدودیت ها 0.129 تعلق گرفت.بر اساس مطالعات انجام شده ،مناسب ترین مکان ها برای توسعه پرورش ماهیان خاویاری در مناطق شمالی و شرق و نامناسب ترین در برخی مناطق جنوبی و غرب استان می باشند

چکیده [English]

At present, the main species of sturgeon breeding in the country is Huso huso, which due to its rapid growth and the possibility of producing enough juveniles in sturgeon breeding centers and high meat prices, especially caviar, in most sturgeon farms in the area. The country has been introduced. Considering the favorable results obtained in two sturgeon breeding and breeding centers in recent years in the north of Khuzestan province, the present study aims to conduct basic studies for talent and location for the development of elephant breeding and breeding centers In Khuzestan province, it was designed using Geographic Information System (GIS). For talent and location, several indicators were used and by combining two models of fuzzy logic and AHP, first each layer was divided in the environment of fuzzy geographic information system and finally in (GIS) of the fit class. Based on the results obtained The highest weight was given to ecological indicators of 0.321, followed by climate 0.205, economic and social 0.179, natural 0.167 and barriers and constraints 0.129, respectively. According to studies, the most suitable places for the development of sturgeon farming in the northern regions and East and the most unsuitable in some southern and western regions of the province
