The western part of Warsaw basin covered by the Kampinos National Park, exists as a space system mainly consisting of 3 laying evenly with a parallel of latitude links: south, central and northern. As far as chemical and hydrological features are concerned, the south one is quite strongly subordinated to the area of glacial plains. The central link embracing the depression of Łasica river and situated along a belt of dunes, shows a significant function autonomy. Here the substances transported as a colloidal solutions have a essential influence on habitats' trophic levels. Strongly changed, already in historical times, by floods the northern link is quite strongly subordinated to hidrological influence of the Vistula river. On the basis of chemical features the homogeneous units of the soil weathering zone were isolated, which could also be treated as a fundamental geochemical landscapes distinctly reacting to any human influence.
