[Objective] To explore the effects of ecological restoration patterns in coal ming areas of Huainan City, including rehabilitation thickness of soil and reestablished vegetation type on soil CO₂ flux, and to provide theoretical basis for ecological restoration patterns similar coal mining region.[Methods] Method of close static chamber-alkali absorption was used to measure the diurnal variation of reconstructing soil CO₂ flux. Meanwhile, temperatures of soil surface and 5 cm depth and soil water content were measured and their influences on soil CO₂ flux were analyzed in different ecological remediation patterns for coal mining district in Huainan City, Anhui Province.[Results] Diurnal variation of soil CO₂ flux exhibited an obvious unimodal pattern during the whole observation period, with peak value at 14:00 and minimum flux at 6:00 for all of the ecological restoration models. The flux ranked at different revegetation districts as:B(brushwood) > C(brushwood) > D(arboreal forest) > A(grassland). Soil CO₂ flux of B and C districts were significantly higher than that of A(p<0.05); no significant differences among others were observed(p>0.05). Soil CO₂ flux with different rehabilitation thickness ranked as:40-80 cm > 0-20 cm > 20-40 cm > 80-100 cm, and their maximum and amplitude also followed this order. Significant relationships were found between soil temperature in 0 and 5 cm depth and soil CO₂ flux, which could be described by exponential equation. R² ranged from 0.34 to 0.70 and from 0.48 to 0.83, respectively. Relationship between soil CO₂ flux and soil water content can be described by quadratic equation, with 0.08~0.44 R² value.[Conclusion] Soil CO₂ flux differed under different vegetation types, the highest occurred in brushwood[5.22 μmol/(m²·s)], followed by arboreal forest[4.56 μmol/(m²·s)], the lowest was grassland[3.89 μmol/(m²·s)].Except for 40-80 cm thickness, soil CO₂ flux decreased with the increase of soil rehabilitation thickness. The influence of vegetation on soil CO₂ flux was more significant than the one of soil rehabilitation thickness.
