Abstract

The paper links vegetational microlandscapes distinguished on the basis of differentiationof actual vegetation with geobotanical sub-districts defined on the basis of differentiationof potential vegetation. For each of these microlandscapes an actual and potential vegetation,as well as land-use were analyzed; the analysis being performed for an area of ca. 540km2 of theVistula River valley. The spatial structure of these microlandscapes was characterized in termsof various landscape metrics. The analysis reveals that comprehensive treatment allows microlandscapesto be aggregated into typological (and potentially regional) units of a higher rank.However, the relationships between vegetational microlandscapes and geobotanical regionalization,based on potential vegetation are not unambiguous.

Keywords: actual vegetation, potential vegetation, landscape metrics, vegetational microlandscapes, Vistula Valley, Poland
