This elaboration’s aim is to show topoclimates` differentiation in the area of the Rybnik Plateau. Effect of land use and relief on a heat balance structure of the chosen area is presented on basis of the archival cartographic materials and subject literature. The albedo values (tab. 1), absorbed radiation sums, as well as their deviation at different relief (tab.2) were undergone the analysis. Table 3 presents data, collected from 1995 to 2000, related to a seasonal course of the heat balance elements for the various ecosystems. Com-parison of the heat balance factors given in the tables and their values (W/m2) let to determine participation of surfaces with domination of heat exchange through evaporation over surfaces with convectional heat exchange. This analysis was made on basis of the Bowen coefficient (tab. 4).
