Zmiany krajobrazu w Dolinie Wisły Środkowej okolic Kazimierza Dolnego w latach 1953 -2003

The article presents changes in the landscape which occurred in the structure of utilization of the grounds in the years 1953 - 2003, concerning a segment of the Vistula river in the proximity of Kazimierz Dolny. The river is distinguished by its outstanding natural and landscape values. Its present values of biodiversity are high in comparison with other rivers in western Europe. The changes in the landscape were investigated on the basis of an analysis of the ecotopes from two time intervals (1953, 2003) which were performed with the use of photointerpretational techniques and GIS software. The created maps mainly presented the differences in the course of the riverbed, but also showed the changes in the units connected with natural plant succession, which could have resulted from the growing intensity of crop cultivation and the influence of regulatory works in the Vistula valley.
