For the identificial on of saline soil area and halophytes and investigation of salt tolerance mechanism and introduce suitable salt tolerance plant in rangelands wedoing this research in the estern of semnan province for the plant analyses from the use trancect and plots range my work was the near kavir (playa). In the basies this research identification 74 plant spesies with the 17 type plant and 850 hectar area. Maxec was 313.5 in the type plant tam-hal and min EC was 26 mm in the type plant alha with 8.08, min in the type with 71.5 in the type Tam max NA in the type plant Tam-Halo with the 5550, Me/lit and min in the type plant sedi with the 12 Meq/Lit and max HCO3-1 IN the type plant At-Ve with the 5.9, min in the type plant pros with the 3.7 Meq/Lit and max CL-1 in the type plant Tam-Halos 5510 and min in the sedi with to Meq/Lit max SO4-2 in the type plant phra 1630 and min 26 in the sedi and the kand of salin 6 Total sample was koloredy and to tal soils was sal in soils and frame Total sample 51/1 prsent was silt-lime and 18.4 present was sandy lomeand 11/27 present was lome.The catogory of plant ratio depe water the firs was phreatophyate ofter iricohyodrophtae ofter than was hydrophytae the catogory of reaction ratioto the EC soil, max namber was evasion after tolerance ofter then avoidance.
