Adsorption of particles with nearest- neighbor repulsive interactions is studied thrugh Monte Carlo simulation on bivariate surfaces characterized by patches of weak and strong adsorbing sites of size l. Patches are considered to have square geometry and they can be Esther arranged in a deterministic ordered structure or in a random way. Quantities are identified which scale abeying power laws as a function of the scale length l. consequences of this tinding are discussed for the determination of the energetic topography of the surface from adsorption measurements.
