Abstract

This zone which is studied is located in north eastern of Tehran with 45 to 77 kilometers in distance in Tehran –Firoozkouh path, and it is between 51/ 59 to 52 /23 east longitude and 35‏/ 35 to 35/ 45 north latitude. The height of this zone from sea surface (in the lowest part 1800 and the highest part 2300 meters) and the area of total studied area was 20.000 hac.The stages to this research were Soil Survey, Soil sampling, Laboratory analysis of soil samples, Collection of Climatic farming System for Selected Crops. Soil Suitability mapped with the use‏ of GIS system, and evaluation of qualitative Land Suitability for LAND UTILIZATION types in the study area. For qualitative evaluation of Lands data’s from detailed soil Survey, studies and Climatological figures and Topography Characteristics were used as the physical parameters, as Compared with crop requirements of using the standard and rating tables of sys and PARAMETRIC METHODS proposed by FAO in 1973. Qualitative evaluation was carried out according to both SIMPLE LIMITATION and parametric approaches by comparing climate, topography and soil characteristic to crop requirements. Results of qualitative land evaluation indicated that the climatic characteristics will cause limitation of %5.5 and %37.5 respecting for SAFFLOWER- SOYBEAN growth and production in the research area some. soil characteristics and topography are limiting factors too. For All production, the main limiting factors included percentage of calsium. For SAFFLOWER: the limiting factors included Coarse fragment and Relief and PH. For SOYBEAN: : the limiting factors included Coarse frag‏ment.Based on actual yield of crops in studied region the square root method was superior to simple limiting method in determining land suitability of land units.
