The history of Lake Rzecin and its surroundings drawn on maps as a background to palaeoecological reconstruction

摘要: The article presents the results of landscape analysis surroundings Lake Rzecin in Notec Forest depicted on cartographic materials. Morphometrical and changes water conditions were conducted. Thanks to many data, lake geometry could be observed during almost whole last two centuries. show that major impact rate level decrease hundred years was due melioration works. Two periods rapid surface can this time. first occurred as a result creation Ditch, which probably took place middle 19th century; second, all likelihood, with its cleaning out; exact date operation is not known but map suggest it have happened between 1958 1966. Due these events decreased by 73.6% analysed period. Apart from phenomenon area seems quite stable: there some fluctuations; however, did exceed more than 5%. That why assumed human factor has biggest influence succession ecosystem. Analysis collection shows centuries no huge local landscape; other historical sources do confirm this. According them, only man also fires insect gradations had an enormous Nonetheless, land use structure within Ditch catchment change great deal; most significant modification increment forested areas 74.1 up 85.1 %.
