Sažetak
Forest fire-prevention roads (FFPR) are a special category of forest roads connected to the Mediterranean and Submediterranean area, i.e. to the area where forest fires represent the greatest danger of total biotic and abiotic factors harmful to the existence of forest ecosystems. Research on the most important factors which influence the spatial distribution of the network of forest fire-prevention roads of high quality, as an important factor in the preventive measures against forest fires, has been carried out in the management unit Senjska Draga in the area of the Forest Management, Senj. The results of the research showed that one third of the existing forest fire-prevention roads were laid with a higher longitudinal gradient than permitted, an average geometrical distance determined by a centroidal method, and by the application of the personal computer and digital terrain model (DTM) is 244.79 m, and its real equivalent is 287.15 m. Using the relative openness and the new method of bordered areas, it has been established that the researched management unit is satisfactorily open for the average geometrical distance of access to the forest area from 250 m and more. On the theoretical model, due to various influences of factors, it has been shown that forest fire-prevention roads should be designed at a distance of 300 to 600 m apart. In order to choose the most acceptable costs for forest fire-prevention roads, the computer programme COST has been created, and calculations are based on the derived mathematical expressions. Costs of excavations depend on many factors that have been analysed in detail, and according to the research of the normal transversal profile, the more economic method of building forest fire-prevention roads has been suggested.
