Abstract
The paper presents a spatial and temporal analysis of the distribution of the soil salinity and its pH level of south-east Poland depending on selected environmental factors. The area under examination (Carpathian Foredeep, Carpathians flysch) is distinguished by its specific hydrological and geological conditions (the Vistula and the San valley). The research works were performed in relation to parameters that had been measured in-situ in 1995, 2000, 2005, and 2010. Using specialist GIS software, proper interpolation procedures were performed, which enabled visualization in the form of raster and vector maps for the spatial distribution of the examined soil properties. Moreover, an analysis of remote sensing data was completed. Based on the analysis, it was discovered that the biggest changes in all examined soil parameters took place in 2010 - changes in the soil salinity and its pH level, as well as in the content of potassium (K) and sodium (Na). Those changes occurred mainly in the north and south parts of the examined area. The underlying reason for those changes might have been the flood, which hit the region in June 2010.
