Problems of Holocene climatostratigraphy on the territory of Poland. Leszek Starkel Department of Geomorphology and Hydrology, Institute of Geography, Polish Academy of Sciences , 31-018 Kraków, ul. św. Jana 22, e-mail; starkel@zg.pan.krakow.pl Abstract The presented climatostratigraphy of the Holocene on the territory of Poland is based on a range of biotic, sedimentological, geomorphological and isotopic records, but also takes into account fluctuations of temperature and hydrological regime. The author upholds the traditional division of the Holocene into three thermic phases and discusses in detail distinct fluctuations in the hydrological regime reflected in the alteration of wetter and drier phases. Althrough their profiles tend to be blurred, the lower boundaries are the wetter phases, which set off the transformation of geoecosystems (a process reflected in the first clusters of extreme events), may be used to identify regional stratigraphic subdivisions. The superimposed phases of human activity have much smaller spatial extend.
