Geoecological features and typology of karst landscapes of the southern part of the Vis Island (Croatia)

In this study, the analysis and typology of karst landscapes of the southern part of the Vis Island was conducted. Typology is based on the analysis of structural and functional characteristics and patterns, which was obtained from parameters of lithology, geomorphology (slopes) and vegetation. The aims of the analysis were to distinguish homogenous (complex) landscape types and to determine their structural and functional features, on the basis of their dimensions, morphology, frequency of occurence in the landscape and their interrelations. This is of importance, because specificity of this landscape features is of great influence on stability and sensitivity of existing geo and ecosystems, as well as on their internal and external dynamics. The results obtained by analysis and comparison of frequencies of occurences of the particular combination of parameters in homogenous landscype types, morphology, extent and interrelations of different landscape types, can be reliable indicators of abiotic and biotic landscape elements balance, as well as of existing processes. Also, they can be useful as methodological framework for estimation of future landscape and environmental changes in whole. This can be platform for corresponding conclusions which can be useful for making decisions in landscape management relevant for preserving karst landscapes of the Vis Island, as well as other similar areas in Adriatic and Mediterranean. The use of GIS, as very important tool in landscape analysis and evaluation, enabled more detailed analysis of specific parameters relevant for determination of complex landscape types, as well as synthesis, through determination the relationships between elements of internal structure, spatial function, interrelations between landscape types and their complex influence on natural and changed cultural landscapes and environment of the southern part of the Vis Island.
