Popis / Abstract:

Many indicators trying to assess the state of such a highly complex system have been created so far. In this paper, we present the use and usefulness of surrogate measures of the ecological stability assessment in an environmentally-affected area. The cadastral territory of the municipality Rudňany, located in the Slovenské rudohorie Mts. (Eastern Slovakia), was used because of long term impact of mining and processing minerals. The large-scale analysis of the secondary landscape structure was based on aerial photography from 2013, field research and delineated land cover classes on the 5th hierarchical level. The modified Indicator of Ecological Stability – IELS was calculated for the whole study area and also separately for the grid areas of the size 100 × 100 m. Used measures include landscape diversity, the weighting score of hemeroby and the character of ecological corridors and barriers. Identification and inventorying of land cover classes at a scale of 1:10 000 with respect to the minimum mapping area of 0,1 ha resulted in a decrease in the IELS. It was verified by a bottom-up aproach and a layer based on nomenclature for Phare countries. The lower value of the IELS is related to the possibility of more detailed mapping of the real state of the landscape structure and its importance for ecological stability of landscape. Used grid method revealed high IELS in squares representing transitional zones between adjacent ecosystems – ecotones.
