The objective of the study was to assess the environmental stability of land surface in Poland over time and space. The study showed that the level of ecological stability of land was low, approximating long-term average, and showed no variation over the years. The province of Lubuskie with its extensive forest areas is standing out for its high level of stability. The environmental status of land surface is shaped mainly by such land use forms as arable lands, forests and permanent grasslands. Land use pattern in Poland is undergoing two major kinds of change: lands sown to annual crops, lands under forest and urban and built-up areas are increasing whereas grasslands, lands under perennial crops and idle lands are decreasing in area.
