Abstract

 Presence of every herbaceous species was not suddenly. But it is created base on special relation that result from relation between Environmental factors and species nature. The most extent of GolestanProvince,over 167000 hectares, are impressed from salinity and alkalinity and establishment of saline species depend on these relations. The purpose of this investigation is determination presence of Halostachys caspica pall species Gomishan range of GOLESTAN PROVINCE and determination most important efficient factors in their distribution at intended Area. For this aim, at first intended area was specified on the field and topographic map then divided into the region (high density, semi- dense and absence) and at the end of the wet period was provided soil profile and samples in the Randomized– systematic method of rooting depth of species to determinate some of the PHYSICOCHEMICAL CHARACTERISTICS of soil Soil sample were taken atdepths of 0-30 and 30-60 cm. In laboratory physical and chemical characteristic included Clay (%), Silt (%) and Sand (%), EC, pH, organic material (%), N, P, K were examined. Using SPSS package, variance and Duncan test were applied to analyze the data. comparing result indicated that EC, P and have the more effect Between chemical properties of soils on the distribution of Halostachys caspica species at Gomishan range and showed that there is an indirect relation between Presence of species and salinity and a direct relation with P and K quantity
