Immense complexity of natural environment, immeasurability of its characteristics, duality of its nature (continuous and discrete phenomena), diversity of reference units pose the problems in the research on the environment. It is proposed to assume geometric units as objects that deliver particular information on chosen components of environment. The size of reference units is adjusted to the research area (Lower Silesia) and to the presentation of the outcomes in the form of cartographic models. Five features are taken into consideration: occurrence of low fertility soils, water erosion, slope, altitude above mean sea level and fractal dimension calculated for low fertility soil. These factors were chosen regarding the land management conditions. Moreover one of the characteristics – box dimension – expresses the geometry of the research phenomenon. Classification is carried out with use of chosen areal methods and the outcomes are presented in form of cartographic models which may be use as a background for presenting other environmental phenomena or indices characterizing it.
