Abstract

Given the potential for carbon storage in plant tissues, this approach has a serious interest in recent decades. Therefore, the ability of carbon storage in Astragalus gossypinus and Astragalus parrowianus were examined in part of alpine pastures in Kermanshah Province. After determining the representative districts, according to 4 main aspect and 5 category elevation was determined representative area. Also in each representative area 3 transect parallel to of up slope to down was placed(total 60 transect) and interval 10 m was placed plots(total 300 plot) and aerial and underground biomass carbon values of those species were measured. Regarding to the results of mean compression SNK the least of carbon storage in category elevation(1900-2100) that was determined in north aspect. Also according to the results, Astragalus parrowianus Species has more carbon storage capacity than Astragalus gossypinus species. This ability is due to more vegetation percentage and more aerial and underground biomass of Astragalus parrowianus Species in compare with Astragalus gossypinus Species. These abilities cause to more organic carbon storage of Astragalus parrowianus Species.
