The Agroclimate Zoning of Grainy maize using GIS Techniques in Lorestan province

Climatic factors are the most important variables among effective factors in agricultural production. In this study, climatic parameters including temperature, precipitation, degree day and environmental parameters such as slop aspect, hydrographical network and distance to streams and soil are exerted. In order to achieve this goal, first the date of crop production, and then environmental are collected and finally their maps were produced using methods in Arc GIS software. These maps are standardized with fuzzy logic and criteria specified for grainy maize implant and then each of them is taken specific weight. In the next step, all of the standardized maps are integrated using AHP logic and subsequently, the appropriate location for grainy maize plantation zonation map in lorestan province is identified. Results reveal that, 299521 hectares are so suitable for grainy maize implants, 809956 hectares are suitable, 1040944 hectares have a medium capability, 529535 hectares are unsuitable, and 95930 hectares are so unsuitable for this purpose. Final result of this study indicates that each climatic and environmental factor according to the different regions have specific capability for grainy maize plantaion and these recognized capable areas needs to be considere for future plannings.
