In this study, the initial assessment of carbon storage in plant communities of Lycium depressum Stocks and Zygophylum fabago L. was done in the Meyghan playa, Arak. Plant sampling was done by the random-systematic method. To determine the aboveground and underground biomass, a clipping method was used, and these organs were weighed separately. The organic carbon of plant samples was determined by the ash method. Soil studies were performed in each plant type, in the depth of plant rooting, as well as in areas without plants. The data were analyzed by SPSS24 software. The results showed that the soil and plant average carbon sequestration of Z. fabago habitat was 14.61 and 0.18, and in L. depressum type was 13.8 and 0.425 ton/ha. This difference was not significant at the 5% level. Soil carbon sequestration increased significantly in areas covered with studied species (t = - 6.902, p < /em> = 0.001), compared to the areas without any vegetation cover. The carbon conversion coefficient of above and underground organs of the studied plants was significant at the level of 5% and the carbon sequestration of aboveground parts of the plant to underground carbon sequestrated ratio in Z. fabago and L. depressum was 2.43 and 2.08, respectively. Considering the carbon storage capacity of plants studied (in the soil and plant), it can be concluded that these plants can play an important role in carbon sequestration at the least possible cost, and mitigation of climate change consequences in arid regions.

Atmospheric carbon dioxide has noticeably increased in recent decades.Experiences show that restoration of vegetation could cause carbon to be stabilized in plant tissues, called carbon sequestration.This research was aimed to compare the potential of biomass carbon sequestration in the planted vegetation types of Haloxylon persicum and Atriplex canescens and natural vegetation types of Salsola incanescens and Atriplex verrucifera in northwest of Meyghan desert, Arak. In each vegetation type, aboveground and underground biomass were measured for the dominant and companion species.Results showed that in all vegetation types, the amount of carbon stored in aerial biomass was higher than of underground biomass (2.61 times for the average of all vegetation types). The total biomass carbon sequestration of H. persicum, A. canescens, S. incanescens and A. veruccifera was531.19, 228.79, 207.77 and 91.61 g/m2, respectively and the average of H. persicum vegetation type showed a significant difference with other types. Our results clearly show that after 20 years of vegetation restoration, planted vegetation types of H. persicum and A. canescens are evaluated as successful in terms of biomass carbon sequestration.
