Abstract :

The information for spatial and temporal variation in the distribution of forest ecosystems is essential for determining tendencies in alteration of the forest area size and structure under the conditions of climate changes and existing management of the forest. The paper presents spatial models of xerothermic oak ecosystems distribution in SCI “Zapadna Stara Planina i Predbalkan” in 1977, 1992 and 2007, as a result of the conducted simulation on the base of the studied forest vegetation reflective characteristics. The modification of occupied areas by altitude, exposure, slope, soil type and bedrocks has been analyzed. The climatic fluctuations are characterized by deviations of de Marton index. The ecological status of communities is determined by calculating of state vector and the output factors having the greatest weight to the established state are obtained. The comparative spatial analysis of ecological status presented in the paper and the dynamics of the forest vegetation is the result from the application of a combined investigation method – processing of satellites, aerial photo (orthophoto), GPS and overground data in the using of aerospace technologies and modeling in GIS environment. The created spatial models can be used in the monitoring of the forest ecosystems, for conservation of the forest flora and vegetation, for sustainable management of the forest areas, as well as and for investigation of xerothermic oak forest vegetation in other regions and protected zones.
