Because Geno protected area didn’t protect enough, it cause to use lots of part for domestic animal productivity and this ecosystem with special plant and animal species degrade. This study was down with this goal: determining of proper region for soil protection, rehabilitation and special use according dry region potentials. We use these maps: slope, aspect, elevation, soil, plant cover and rural settle regions and then we categorized them with ArcGIS9.3 according Makhdom ecological modal and then we prepare shape earth units map and final zoning map. Although we numerated erosion factors according MPESIAC method and after adding numbers, sediment delivery identify determined. Results show that 12457.01 ha or %28.02 from total of region is protected zone, 203.82ha or % 0.45 from total of region is rehabilitation zone and 95.591ha or %0.21 from total of regions is special use zone. Results from identifying sediment delivery shows that Ziziphus spina-christi plant type with 87 numbers has forth sediment delivery class or high erosion that the most important factor depends on river erosion and slope. Results show that soils around one fifth of region is eroded intensively and a lot of plant and animals damaged in Geno region. This fact shows that human use a lot from Geno protected area that we must think for protecting more.
