Forest ecosystems and their optimal management can play effective roles in mitigating the carbon emission as well as absorbing the atmospheric carbon. The present research was carried out to determine the effects of 21 year old stands of Cryptomeria japonica, Cupressus sempervirens, Pinus taeda, Acer pseudo-platanu and mixed plantation and natural forest stands on sequestration of carbon in the soil of Chamestan plantation area. The results showed that the difference of carbon in pure, mixed and natural stands, in different layers are statistically significant. Moreover, there are not any significant correlations between the acidity of the soil, nitrogen, salinity and phosphorus and carbon sequestration. For the total layers of the soil (0-45 cm), the rate of carbon sequestration in natural stands (108 ton/ha) was significantly higher than other stands) P<0/01 (. The results of stepwise regression showed that nitrogen percentage and C/N ratio were the most important factors affecting the soil organic carbon content. Overall, it can be concluded that programs of land restoration can be followed in terms of carbon sequestration through the identification of plant species with high potential for carbon sequestration and also evaluation of effective management factors.
