【 摘 要 】

This study analysed spatial and temporal changes in protected landscape of la Landscape Park in Poland, covering an area of 7724 ha. The main objective was to determine level of landscape change of the research area after Polish accession to European Union by comparing land-cover maps from 2004, 2009 and 2014. With the use of prepared land cover maps, we developed a database of the surface of the main elements constituting the background landscape of the research area. The data obtained made it feasible to assess the level of change in two different periods of time (2004 - 2009 and 2009 - 2014) by means of the landscape change index (LCI). This indicator is described by one value which is the result of all the change types taking place in the background landscape in a given period of time. Comparing the index of different parts of la Landscape Park helped to identify areas where the landscape changes were the highest and areas where the changes were hardly noticeable. The results show that when we take into account whole research area landscape changes are much more intense in the second of the analysed periods of time (2009 - 2014) (LCI=1,91) then in years 2004 - 2009 (LCI=0,71). The same analysis was done for each part of municipalities located within the Park. This made it possible to determine which part of the park is the most threatened by spatial transformations. In this context, it should be emphasized that the highest rates of landscape changes were recorded in the municipalities where the largest new residential area was located - in the municipalities Sobótka and lagiewniki. Whereas municipality Dzieroniów with a high percentage of forests inside the Park and unchanging area of arable land have the lowest landscape change index.
