The direct measurement in the air of drill-holes has indicated that the concentrations depend inversely on a pore dimension. The simplified relation between the drill-hole diameter and CO2 concentration, c0(CO2) = (c(CO2)- bD)/(1+aD) was proposed, where c0(CO2) is the CO2 concentration extrapolated to the zero drill-hole diameter in ppmv, c(CO2) is directly measured CO2 concentration in ppmv, and D is drillhole diameter in cm. a and b are parameters in cm-1 and ppmv cm-1, respectively. For the karst soils formed at grass field and deciduous forest, the values of a and b parameters were determined as -0.146±0.012 (standard error) cm-1 and 262.0±56.3 ppmv cm-1, respectively. The dependence between cco2 and D was less obvious for the heavy clay soils of coniferous forest. To understand the dependence better, a conceptual model was created taking into account the concentration gradients and mass fluxes. ER -
