Aims & Backgrounds: One of the most important parts of the planning and management of arid areas is the determination of compatibility of the target area for proper land use. The aim of this study was to emphasize the importance and role of Classification of land suitability evaluation as one of the main parts of the management in arid areas.
Methodology: This study was carried out in the Rigan county located at130 km from the southeast part of Bam city and in the border of Kerman and Sistan-Baluchestan provinces. Field studies, site selection, drilling of 130 soil profiles and soil sampling from 130 points, were conducted in the area.  The Thematic maps were prepared through the satellite images, geological and elevation maps, meteorological information and the results of laboratory analysis. The productivity of sorghum bicolor and maize were selected considering the importance of these products in providing livelihoods and income for the residents of the area.
Findings: The area was very arid and the two curves of temperature and precipitation changes did not match in any months of the year. The water quality of the investigated wells was based on the Wilcox diagram in two classes of C4S3 and C4S2. The degree of lands suitability of the area for a variety of selected productivity was 3 and it was in the state of temporarily inappropriate and permanent inappropriate.
Conclusion: Future suitability of the lands especially after civil operation as well as adaptation of environmental conditions (soil and soil) to the needs of plants in some areas are improved and the severity of the restrictions is reduced and the degree of land suitability is 2 and 3. We can help to the development of arid areas and prevents the disturbances of the balance in the environment and its damages by conducting the studies of site detection, observing the management principles of arid areas and applying knowledge of the day in addition to the local experience.
