It means that the rate of soil respiration does not depend on the depth from the surface but depends on time only. Based on the above idea, an analytical solution of the unsteady diffusion equation is obtained and a method for estimating the rate of soil respiration by applying the experimental results of CO2 concentration in the soil is discussed. Following a manner of chemical kinetics, it is found out that the rate of soil respiration is proportional to the mass of compost introduced and the Q10 value representing the temperature dependence of soil respiration is about 2.5 on average, which is smaller than the value 3.0 obtained by Monteith et al. The theory of estimation of soil respiration and the procedure to make up an experimental equation proposed here will be useful to get the basic information before investigating the prevention of snow mold.}, pages = {145--152}, title = {反応速度論を用いた土壌呼吸速度のモデル化}, volume = {51}, year = {1995} }
