In this paper, the characteristics of mean wind profiles and meanturbulent diffusivity profiles within the wheat field are calculated anddiscussed". The results show that mean wind profiles and mean turbulentdiffusivity profiles within the wheat field can be represented by an exponential function as follows.u(z)=u(H)exp[α₁(z/H)-1)],K_m(Z)=K_m(H)exp[α₂(z/H)-1]。α₁,α₂The results of a1, a2 are compared with that of another authors.
