Abstract

Land evaluation is the estimation and determination of land utilization type for several proposed land systems in the region. In this study, ALES SOFTWARE was used for physical and economical evaluation. The area’s extension is about 656 hectares, which is located in West of Qazvin in latitudes of 36o 6’and 36o 11’ N and between longitudes of 49o 35’and 49o 40’ E. The average height of the above-mentioned region is 1428 meters and the climate information of Takestan station with 238 mm precipitation as well as Khorramdareh station with 297 mm precipitation was utilized. In the study area, the lands under rainfed cultivation were determined by using satellite images based on soil maps, topography, and the region’s climate; and seven profiles were excavated in LMUs. Results showed that while the most limiting factor in this land was the plant water requirement, the rooting depth and erosion state as well as soil nitrogen and organic matter fertility were the trivial to moderate restriction factors in some units. The results of the ALES SOFTWARE revealed that the rainfed WHEAT in land units 1, 2, and 3 had S3 fitness and in land units 4, 5, 6, and 7 had S2 fitness. Moreover, rainfed BARLEY in land units 1, 2, and 3 had N physical fitness and in 4, 5, 6, and 7 had S3 fitness. In this study, the economic fitness classes, obtained by ALES, included S2 and S3 for rainfed WHEAT and S3 and N for BARLEY. The results obtained from the study of WHEAT and BARLEY indicated that WHEAT cultivation had priority over BARLEY due to the fact that BARLEY had more yield reduction than WHEAT, regarding the planting time for it in the region.
