ABSTRACT
In the paper we introduce the results of mapping and spatial analysis of volume [t.ha-1] distribution of particular fuel types in the forests of the Slovensky raj National Park that were affected by a fire in 2007. To map and quantify the particular fuel types in study area we used the Trimble GeoXT device to record the position of individual study plots, which the weight and the height of particular forest types (layers) were measured on. Data measured were processed in ArcGIS Desktop 10 environment. Results were saved in tables and raster layers with the spatial resolution of 2 meters. These results contain information on volume of surface forest fuel types in different types of terrain. The most of fuel was stored in valleys with lower value of curvature, and the least of fuel was stored in ridge positions with higher value of curvature. We introduce also the values for different altitudes, aspects and slopes. The information on forest fuel distribution and its volume is required as input information for modeling of forest fire behavior in the majority GIS based fire behavior models, e.g. FARSITE, FlamMap. To know the behavior of forest fore ahead is a very good prerequisite for planning of effective fire preventive and mitigation measures to protect the human lives, their property, but also environmental and economic interests and values.
