Abstract

The area of south slopes of Svilaja was selected for determination of the landscape change. The main aim of the research is modelling of landscape change and possible cultural landscape transformation of the researched area with the help of the geographical information system and formulation of a general GIS models for analysis of general and/or cultural landscape that can be used as a general framework for further researches with smaller adjustments and variations of variables depending on characteristics of the selected area. Applying comparative analysis of the geological basis, pedologic units, vertical analysis of the relief, erosion and antropogenous influence we have shown the nature, dynamics and types of landscape change of the researched area. Processing the worthiness of the forest habitat and estimating generally useful functions of forests, we have shown positive forestation processes on the researched locality. The fire danger estimation has been applied as a corrective factor for change projection modelling. South Svilaja slope changes were monitored during three time periods: the initial, from 1830 to 1846, transitional, from 1975 and contemporary, from 2004 to 2010. The superficial vegetation cover and the manner of soil usage on the researched area were determined for the stated periods. The superficial vegetation cover was the basic criterion applied to classification of south Svilaja slope landscape. Landscape types were diversified on the basis of the generalisation of data on the surface vegetation cover for three stated time periods. Seven landscape types and 18 subtypes were diversified. Overlapping the stated maps with the help of GIS technology, we made a unique map showing south Svilaja slop landscape types through three stated time periods. Applying data processing we determined the imprint of the population. Landscape type monitoring was based on the diversification of main landscape types for the initial period, monitoring of its changes during the transitional period by the contemporary period and monitoring of antropogenous influences on landscape type changes. A unique map was made showing trends of South Svilaja slop landscape changes. The emphasised antropogenous influence is shown in different change trends. Change trends such as melioration, forest degradation, extensification, landscape type disappearance were diversified as well as areas not including landscape type changes. Melioration works would be continued as the dominant landscape process aimed at mitigation of surface erosion. The researched area makes a part of the Counties of Šibensko-Kninska and Splitsko-Dalmatinska and development areas are determined in their Physical Plans. The potential of the research area can be exploited through traffic and other economical structural planning.
