Vol. 18, 4/2010 MoraVian geographical reports Fig. 9: Stable plots (1782 – 2003) SW. These areas represent the best preserved forest ecosystems, which belong to the Slovak Paradise National Park (SW) and the Volovske vrchy Hills (SE). The basin’s bottom was mainly used as arable land in the studied period. The total unchanged land use area (mostly forest and arable land) covers 33% of the territory (Tab. 2). Due to the low spatial accuracy of historical maps (1782 and 1822), the results might be biased (for example, grasslands' areas were considerably overestimated in 1782). 4.3 Absolute land use change intensity Table 3 shows a total sum of changes, which have occurred in the territory, their area and percentage. The largest area belongs to unchanged land use forms, followed by the areas with lesser intensity changes (1 – 2 or 3 – 4). Fig. 10 (see cover p. 3) documents the areas that experienced the most intense changes, which are located at the perimeter of the basin, mostly in the N and NW sections. They are obvious in the vicinity of Levoča. These areas mostly refer to the shift between arable land and forest. Areas with a smaller total sum of land use changes are located in the middle of the basin where arable land has changed to grassland. Exceptions to these trends are localities between Spišská Nová Ves and Levoča and in the southeast of the village of Spišský Štvrtok, which lay on a hilly landscape where the change was between forest, grassland and arable land. 4.4 Relative intensity of land use change Table 4 presents trends of the land use change and its percentage. The largest part of the studied region (67.1%) has experienced either no change or its land use has returned to the original form during the studied period. In the changed areas, extensification (18.2%) slightly prevails over intensification (14.7%). The most preserved or returned areas are located in the SE and Land-use forms built-up area Grassland Arable land Forest SUM Ratio [%] Area in [ha] 178.70 43.40 10,528.71 7,835.34 18,586.15 33.3 Number of polygons 30 63 731 295 1,119 Area of the largest [ha] 67.24 5.61 1,067.83 2,573.47 Tab. 2: Stable land use forms areas in 1782 – 2003 17
