The model for describing kinetic properties of adatoms on an anisotropic substrate is proposed. The kinetic equation for 1D adatom localized structures is constructed in the frame of the Sine-Gordon model. The self-diffusion coefficient for adatoms is calculated and the process of their homogenization is discussed.
