The present study was carried out to investigate the effect of two species of Pinus eldarica and Robinia pseudoacacia on soil properties and carbon dioxide emission in the Khargoosh dareh forest park in Tehran. For this purpose, four plots of 20 × 20 meters sample were selected randomly and soil sampling was carried out from the center of each sample plot at a depth of 10 cm. Also the carbon dioxide emissions were measured at 35 points per stand. In order to investigate the effect of seasonal variation on Co2 emissions, measurements were done in both spring and autumn. The results showed that Robinia pseudoacacia increased potassium, nitrogen, phosphorus, electrical conductivity, organic carbon and nitrogen sequestration in soil compared to Pinus eldarica, but the acidity, organic matter, calcium carbonate, bulk density, moisture content, soil texture and carbon sequestration did not show any significant difference between two species.
