Abstract
Quantifying landscape pattern and its change is essential for the monitoring of changes in ecosystem services caused by
urbanization and other processes. Landscape indicators can be very useful for such assessments. The authors used landscape
metrics for a gradient analysis of land cover between cities and protected areas. The two cities Dresden (Germany) and Poznan
(Poland) were chosen, because they are comparable due to inhabitants, area and location in former socialistic regimes. The
biggest difference affects legal and socio-economic conditions. Overall, the study shows decrease of ecosystem services and
diversity indices with increasing distance from the protected area, but the lines of trend near Dresden and Poznan have a different
course. In comparison to Poznan, around Dresden are more protected areas and much more settlement areas are located near or
even inside them. Protected areas around Poznan are more aggregated and more distant from the town center, have character that
is more natural and are more diversified in terms of land cover configuration. On the other hand, in Dresden, thanks the more
compact character of built-up areas and accompanied green urban areas, the landscape of suburban zone is more diversified and
the benefits of ecosystem services are closer to the people. The reason are more restrictive legal aspects of spatial planning in
Germany.
