| 英文摘要 | In this study, we analyzed the change characteristics of plants and soil about different vegetation duration of restoration in the loess hilly and scientifically evaluated the impact of vegetation restoration on the accumulation, distribution, and relationship of soil organic carbon (SOC) and soil total nitrogen (STN) sequestrations. In our research, the spatial and temporal intergeneration method was used to investigate the effects of different vegetation duration of restoration on SOC and STN stocks in the loess hilly area. Soil samples were collected in the soil depths ranging from 0 to 40 cm from five grassland sites abandoned for 0, 5, 10, 15, and 20 years. The 0-40-cm SOC and STN contents and stocks showed a nonlinear increase during the restoration period, with a decreasing trend followed by an increasing trend, both reached a maximum in 10 years, and the SOC and STN stocks were 34.63 Mg ha(-1) and 2.91 Mg ha(-1). The 0-40-cm SOC and STN sequestrations varied from - 5.39 to 6.58 Mg ha(-1) and - 0.23 to 0.88 Mg ha(-1) respectively. The 0-40-cm SOC and STN sequestration rates varied from - 1.08 to 0.94 Mg ha(-1) year(-1) and - 0.03 to 0.07 Mg ha(-1) year(-1). Overall, natural revegetation 0 similar to 20 years greatly promoted SOC and STN sequestrations through the accumulation of soil nutrient contents, above-ground biomass (AGB), below-ground biomass (BGB), and litter biomass (LB). The soil enzyme activity and soil microbe number were the important factors driving changes in SOC and STN. These results are expected to facilitate future research on SOC and STN to enhance the management of revegetation of unabandoned farmland in the loess hilly region of China in response to global climate change. |
