英文摘要	Soil organic carbon (SOC) was studied across a gradient of 400-550 ppm CO2 in calcareous contaminated semi-arid areas. An experiment was performed under natural and artificial vegetation cover of Atriplex canescens (Pursh) Nutt. SOC and vegetation cover were investigated every 2 years from 2012 to 2018. Findings disclosed that there was a polynomial relation between SOC and CO2 concentration. The SOC change rate had the highest positive relationship with CO2 concentration in the uppermost 20 cm of soil: R-2 = 0.96 and 0.47 in plantation and control areas, respectively. Moreover, plant life forms had a significant effect on the SOC in CO2 contaminated areas (P < 0.01). The highest correlation (R-2 = 0.93-0.99) was observed between SOC rate changes and perennial cover percentage at a depth of 0-20 and 20-40 cm, respectively, through the time.
