Primerjava izbranih krajinsko-ekoloških kazalcev za gozdove v dveh različnih krajinskih tipih

By analysing changes in landscape structure we can trace the influence they have on the evaluation of the diversity function of a forest. In the presented research, it was assessed which indices for computing areas, cores and aggregation tendencies that can be calculated with the Fragstats...
