Abstract:: [Objective] The aim of this study is to explore the effects of different sedimentary layers on the CO₂ production and transport in soil depositional profile, and to provide a theoretical basis for quantitative assessment of the intensity and function of carbon source/sink in the erosion-sedimentary environment in the Loess Plateau. [Methods] Soil columns were filled with sieved soil to simulate the depositional soil layer. Three concentrations of ¹³C-labeled glucose solution(26, 52, 104 mg C/kg)were added to the top(2 cm), middle(5 cm)and bottom(9 cm)of the 12 cm high soil columns. During the incubation period of 10 days at 20℃, the effects of different adding positions and glucose solution concentrations on the apparent CO₂ emission rates were compared and analyzed. The individual contributions from different organic carbon sources to apparent CO₂ were analyzed by comparing the stable isotopic signature of the CO₂ and soil, with the attempts to explore the effect of exogenous carbon input at different layers on the mineralization of sedimentary organic carbon. [Results](1)By adding low-concentration glucose, the mineralization degree of exogenous glucose was 38.6%, 65.1% and 50.9% at the top, middle and bottom, respectively, with significant difference. However, with the increase of glucose concentration, the mineralization degree of each layer tended to be consistent.(2)When the glucose was added at the top layer, the peak value of the δ¹³C in the apparent CO₂appearedthe earliest on day 1 with the highest values(376‰, 1527‰, 3176‰). When the glucose was added to the bottom layer, smaller peaks of δ¹³C in CO₂ emissions(131‰, 236‰, 645‰)were observed and consistently with a time lag on day 2. Moreover, the effects of different buried layer on CO₂ transport and emission were more evident when the glucose concentration was low, whereas little difference was observed when the glucose concentration was high. [Conclusion] The sedimentary layers in depositional sites can significantly affect the mineralization of organic carbon and the transport and emission of CO₂. The quantitative evaluation of carbon source/sink intensity in the Loess Plateau should clarify the influence of the sedimentary layers and concentration of exogenous carbon input from erosion runoff.
