The extent of suchlands are high in Iran and they been increasing under various factors day by day . One of the methods can be using of appropriateplants for such areas . Using of natural flour of the saline areas is one of the main ways to combat against the saline problem sothat we use of maximum utilization of these regions by the least interference in the environment . In this direction , threeperennial salt grasses as names Puccinellia distans ( Jacq .) Parl . , A eluropus littoralis , A leuropus logopoides have been chosenfor this study in saline and alkaline habitats Northern Gorgan .Materials and methods This investigation was carried out in eastern coast of the Caspian Sea . The extent of the rangelands inthis area is １００ ,０００ hectares . In order to study of ecological characteristic , soil type , forage production , plant cover has beenconsidered . In these habitats forage production measured by clipping and weighting method and to use quadrate １ square meter ,Soil analysis were done by below methods in laboratory : texture by hydrometric , electrical conductivity in saturation extractwith electrical conductivity meter .Results Results obtained from present investigation showed that there have been distributed on the saline and alkaline rangelandsof Golestan province .These three species have complete adaptability to the rainfall condition between ２５０ to ３２１mm and meantemperature １７ ℃ , also the climate of the region is semi‐arid and on the basis of Gussan method . Forage production pu .distanshas been between １８７ to ８００ kg / ha , A e . L agopoides and A e . littoralis have ５０ and ２０ kg / ha respectively . The resultsobtained from soil chemical analysis show that Ec A e .L agopoides( L .) T rin .ex Thwaites is between １７ .５ to ６０ ds/m at the areawhich are distributed these species but the main distribution of A e .L agopoides is with the mean salinity ３９ ds/m and A e .littoralis ( Gouan) Parl . is ３１ds/m , also Ec Pu .distans is between ３９ to ５２ ds/m .Conclusions Pu .distans is most suitable for the agricultural areas with ３２１ mm or more annual rainfall . It Good stands havebeen grown with lower rainfall but establishment is more risky .To combat the salinity problem , A e .L agopoides and A e .littoralis send out the salt as salty grains from their various organs ( leave and stem ) and for this reason they have aconsiderable resistance to salinity .ReferencesAbarsaji ,GH . , (１９９６) .
