چکیده

هدف از انجام این تحقیق، مقایسه سه روش‌ طبقه‌بندی اقلیمی کشاورزی فائو، پاپاداکیس و یونسکو جهت تعیین مناطق مناسب کشت گندم دیم در استان کرمانشاه است. به این منظور از داده‌های مشاهداتی 5 ایستگاه همدیدی استان استفاده شد. مطابق یافته‌های پژوهش، بر اساس هر سه روش منتخب، استان از مطلوبیت کشت دیم گندم برخوردار است، به طوری که بر اساس روش فائو، تمام ایستگاه‌های مورد مطالعه در از نظر کشت این محصول دارای پتانسیل اقلیمی مناسب بودند. همچنین در روش پاپاداکیس، ایستگاه سرپل ذهاب دارای اقلیم مدیترانه‌ای جنب حارّه و چهار ایستگاه کرمانشاه، روانسر، کنگاور و اسلام آباد غرب دارای اقلیم مدیترانه‌ای برّی هستند که مبین مطلوبیت جهت کشت دیم گندم می‌باشد. در روش یونسکو نیز تمام ایستگاه‌ها براساس شاخص خشکی و رژیم رطوبتی در گروه اقلیم نیمه خشک قرار گرفتند که از این نظر محدودیت خاصی برای دیمکاری ایجاد نمی‌کند. در مجموع، نتایج حاصل از هر سه روش مؤید مطلوبیت اقلیمی استان جهت دیم‌کاری گندم با عملکردی قابل قیاس با متوسط کشور (حدود 1000 کیلوگرم در هکتار). می‌باشد.

چکیده [English]

The purpose of the current feasibility study was to compare three agroclimatic classification methods namely FAO, Papadakis and UNESCO for determination of suitable regions of rainfed wheat cultivation in Kermanshah province, west of Iran using observed data of five synoptic stations. Application of all three methods revealed that the most regions of the province are suitable for the crop cultivation. Based on FAO method, all study stations showed climatic suitability of wheat cultivation. Application of Papadakis method, on the other hand, showed that Sarpol Zahab weather station have a sub-tropical Mediterranean climate and, Kermanshah, Ravansar, Kangavar and Islamabad have continental Mediterranean climate, which are mainly suitable for rainfed wheat . In case of UNESCO climatic classification, the climate of all five study stations was recognized as semi-arid climate which indicates high climatic potential of the province for growing rainfed wheat. In general, all three method confirm the climatic suitability of the region with average yield of 1000 kg ha-1.
