O článku:
The subject of this contribution is a hilly region in Slovakia–- Myjavská pahorkatina. This hilly land was settled and agriculturally exploited since the 14th century. A typical phenomenon in this landscape are intensive present geomorphological processes on slopes, flood plains, river beds. There is certain traditional hypothesis trying to explain these events. It is the assumption that these processes were caused by changes in land use during 20th century. But the spatial analysis of geomorphological events cast doubt over this hypothesis. The results of spatial analysis anticipate an other hypothesis. It can be hypothesis of metastability. It can be formulated as follows: If we investigate the relief within small time-space dimensions, then it appears unstable, as "full" of local topical events. It we investigate the relief within large time-space dimensions, then it appears unstable, as "full" of regional longlasting irreversible trends. There are some medium scale geomorphological processes and forms "between". This medium scale level behaves like a buffer muffling both forms of unstability.
