AbstractCarbon accumulation is an important research topic for grassland restoration. It is requisite to determine the dynamics of the soil carbon pools [soil organic carbon (SOC) and soil inorganic carbon (SIC)] for understanding regional carbon budgets. In this study, we chose a grassland restoration chronosequence (cropland, 0years; grasslands restored for 5, 15 and 30years, i.e. RG5, RG15 and RG30, respectively) to compare the SOC and SIC pools in different soil profiles. Our results showed that SOC stock in the 0- to 100-cm soil layer showed an initial decrease in RG5 and then an increase to net C gains in RG15 and RG30. Because of a decrease in the SIC stock, the percentage of SOC stock in the total soil C pool increased across the chronosequence. The SIC stock decreased at a rate of 075Mghm(-2)y(-1). The change of SOC was higher in the surface (0-10cm, 040Mghm(-2)y(-1)) than in the deeper soil (10-100cm, 033Mghm(-2)y(-1)) in RG5. The accumulation of C commenced >5years after cropland conversion. Although the SIC content decreased, the SIC stock still represented a larger percentage of the soil C pool. Moreover, the soil total carbon showed an increasing trend during grassland restoration. Our results indicated that the soil C sequestration featured an increase in SOC, offsetting the decrease in SIC at the depth of 0-100cm in the restored grasslands. Therefore, we suggest that both SOC and SIC should be considered during grassland restoration in semi-arid regions. Copyright (c) 2016 John Wiley & Sons, Ltd.
