Wykorzystanie leśnych baz danych dla określenia potencjalnych zdolności retencyjnych Parku Krajobrazowego Puszcza Zielonka

The main role in forming the so-called small landscape retention in the Wielkopolska region is ascribed to the extent of afforestation of a given area – the size of the afforested surface in a catchment species composition and age structures of the stands. Non-climatical, physiographical parameters infl uence water storage capacity in a modifying manner only, nevertheless essential. We can say that they qualify potential water storage conditions. Working from the above-mentioned premises, the original method of potential water storage coeffi cient estimation for the Zielonka Forest Landscape Park has been formulated. The idea of the method is as follows – for each elementary area exclusive potential water storage coeffi cient is assigned. The potential water storage capacity of forested areas of the Zielonka Forest Landscape Park is characterized by relatively signifi cant spatial variability. Spatial distribution of potential water storage coeffi cients for the Zielonka Forest, obtained by herein described method, should be the basis for guidelines as far as water management is concerned in the plans of forest management or for the general land use planning.
