Abstract    In recent years, increasing the awareness on the environmental problems, especially global warming, has increase the concerns about the impact of emissions on the global climate. The current study was conducted to evaluate and analyze the environmental effects of rapeseed production in the form of life cycle using SimaPro software with the aim concentration on climate changes and impact of acidification. In order to perform the experiments, 1 tone rapeseed was used as operational unit. The required data was collected from 30 farms in Izeh city. Ten environmental indexes including depletion of groundwater resources, potential to acidification, potential to eutrophication, potential to global warming, ozone depletion potential, human toxicity potential, potential to toxicity of fresh water and marine fish, potential to environmental toxicity, potential to photochemical oxidation were investigated in this research. Results showed that the amount of greenhouse emissions for rapeseed was equal to 112.73 kg of carbon dioxide equivalent. It was also revealed that chemical fertilizer had the highest share among the evaluated inputs within the life cycle. Results obtained in this survey indicated that management of nutrients and pesticides can be considered as a concentration point for optimizing the environmental influences of rapeseed production in the related region.

چکیده    در سال‌هاي اخير با گسترش آگاهي در زمينه مساله محيط زيست بويژه گرمايش زمين، نگراني در مورد تأثير انتشار آلاينده‌ها بر اقليم جهاني افزايش يافته است. تحقيق حاضر با هدف بررسي، تجزيه و تحليل اثرات زيست محيطي کشت محصول کلزا در قالب ارزيابي چرخه زندگي با استفاده از نرم‌افزار سيماپرو 8 جهت تمرکز بر تغييرات آب و هوايي و تاثير اسيدي شدن انجام شده و يک تن کلزا به عنوان واحد عملياتي انتخاب شده است. داده‌هاي مورد نياز از 30 مزرعه کلزا در شهرستان ايذه جمع‌آوري گرديد. ده شاخص زيست محيطي از جمله تخليه منابع زيرزميني (غير زنده)، پتانسيل اسيدي شدن، پتانسيل يوتريفيکاسيون، پتانسيل گرمايش جهاني، پتانسيل تخليه اوزون، پتانسيل سميت انساني، پتانسيل سميت آب شيرين و آبزيان دريايي، پتانسيل سميت محيط زيست و پتانسيل اکسيداسيون فتوشيميايي در اين مطالعه مورد بررسي قرار گرفت. نتايج بدست آمده نشان مي‌دهد که ميزان انتشار گازهاي گلخانه‌اي براي کلزا 73/112کيلوگرم معادل دي‌اکسيدکربن است و کود شيميايي بيشترين سهم را در بين نهاده‌هاي مصرفي در اين چرخه زندگي داشته است. علاوه بر اين بالاترين درجه از اثرات زيست محيطي در طول فرآيند سميت آبي رخ داده است.  نتايج حاصل از اين بررسي نشان مي‌دهد يک نقطه تمرکز براي بهينه‌سازي اثرات زيست محيطي حاصل از کشت کلزا در منطقه، مديريت مواد مغذي و آفت‌کش‌ها است.
