Abstract

Canola after soybean and oil palm is the world third leading oilseed by producing 15 percent of the global plant oil. Climate, topography and lands fitness are of most important environmental factors on which, the crop production capability in a region depends. By evaluating the lands fitness based on these criteria, has been tried in this study to detect the suitable lands for canola cultivation in west Azerbaijan province. In the present study, the climatological data such as temperature, precipitation, growth degree day, relative humidity, freezing days, sunshine hours were collected from the west Azerbaijan province synoptic and rain gauge stations (since their installation till 1387) associated with the phonologic stages of canola growth. In addition to the climatological data, the ones on earth resources like topographic layers, lands capability, soil depth and lands use were analyzed focusing on the climatological and ecological needs of canola. After generalizing the data and processing the using GIS, their corresponding information layers were derived. In order to prioritize and assess the criteria and information layers and to determine their rate, the multi criteria decision method (MCDM) was employed based on Analytical hierarchy process(AHP). Then, by rating the provided layers based on the criteria and the considered model, overlapping and special analysis of the layers were done in GIS environmental and the final land evaluation layer for canola cultivation was produced. Based on the obtained results, the province lands were divided into four categories of highly suitable(%15.2), suitable(%52.1) , moderate(%25.4) and weak(%7.3). lands accounting for the environmental and climatologocal potential for canola cultivation.

Persian Title: سنجش تناسب اراضي استان آذربايجان غربي براي کشت کلزا بر اساس روش¬هاي ارزيابي تصميم¬گيري چند معياره در محيط GIS
Persian Abstract: کلزا با اختصاص 15 درصد کل توليد روغن گياهي در جهان بعد از سويا و نخل روغني، مقام سوم را در بين دانه¬هاي روغني به خود اختصاص داده است. اقليم، توپوگرافي و خاک از مهمترين مولفه¬هاي محيطي هستند که استعداد و قابليت توليد محصول زراعي در يک منطقه به آنها وابسته است. در اين تحقيق سعي شده است با ارزيابي تناسب اراضي بر اساس اين معيارها، اراضي مستعد کشت کلزا در سطح استان آذربايجان¬غربي شناسايي شود. در تحقيق حاضر از داده¬هاي اقليمي از قبيل دما، بارش، درجه روز، رطوبت نسبي، تعداد روز يخبندان، و ساعات آفتابي، مربوط به آمار ايستگاه¬هاي سينوپتيک و باران¬سنجي سطح استان از بدو تاسيس تا سال 1387 مربوط به هر يک از مراحل فنولوژيکي رشد کلزا و داده¬هاي منابع زميني از قبيل لايه¬هاي توپوگرافي، قابليت اراضي، عمق خاک و کاربري اراضي، استفاده شده، مطالعه و بررسي هر يک از آنها در رابطه با نيازهاي اقليمي و اکولوژيکي کلزا صورت گرفت. با تعميم داده¬ها به سطوح و پردازش آنها با استفاده از فن¬آوري GIS لايه¬هاي اطلاعاتي مربوط به هر يک از آنها تهيه شد. به منظور اولويت¬بندي و ارزيابي معيارها و لايه¬هاي اطلاعاتي در رابطه با هم و تعيين وزن آنها از روش تحليل تصميم¬گيري چند معياره (MCDM) مبتني بر روش فرايند تحليل سلسله مراتبي (AHP) استفاده شد. سپس با وزن¬دهي به لايه¬هاي تهيه شده بر اساس معيارها و مدل مورد نظر، همپوشاني و تحليل فضايي لايه¬ها در محيط GIS صورت گرفته و لايه نهايي ارزيابي تناسب اراضي براي کشت کلزا تهيه شد. بر اساس نتايج بدست آمده، اراضي استان از نظر پتانسل اقليمي و محيطي براي کشت کلزا به چهار طبقه خيلي مناسب (15/2%)، مناسب (52/1%)، متوسط (25/4%) و ضعيف (7/3%) تقسيم¬بندي شدند.
