An Agro-Climatic Zoning of dryland lentil and wheat slew in ardbil Province by using of methods vikor and ahp

Crop production and agricultural potential in each region depends on the weather and climatic characteristics, study the elements and climatic factors affecting agriculture has of great importance. Wheat is the most important agricultural products that contribute to food security and the country's economy. In addition to lentile because of having high protein and quality is important. The aim of this study is to agroclimatic zoning for wheat and lentile in Ardabil province using AHP and VIKOR methods in geographic information system surrounding. In this research, precipitation, moisture, temperature, soil, topography, slope and land use factors have been used. In the next step to find the suitable areas AHP and VIKOR methods were used and after preparing layers and weighting them, were overlaid in GIS and zoning map for both species were prepared. Results showed that based on AHP method, 11 % is very suitable, 30% is suitable, 43% is moderate and 16% is unsuitable for wheat. Also, Results showed that based on AHP method, 6 % is very suitable, 18% is suitable, 29% is moderate and 46% is unsuitable for lentile. Based on VIKOR method, Q value for wheat in Parsabaad 0/98, in Bilesavar 0/87, Nir 0/80, Kosar 0/78, Ardabil 0/75, Namin 0/70, Khalkhal 0/66, Sareyn 0/61, Meshginshahr 0.46 and Germi was 0.08 for wheat. Also for lentile Q value in Parsabaad 0/98, in Bilesavar 0/79, Germi 0.75, Nir 0.57, Ardabil 0.56, Khalkhal 0.44, Sareyn 0.22, Namin 0.14, Kosar 0.11 and Meshginshahr was 0.09. So based on VIKOR methods Parsabaad and Belesavar stations have the most potentials for both species and Kosar for wheat and Germi for lentile have the lowest potential.
