摘要
The Stolowe Mountains (SW Poland) represent a unique Central European example of a sedimentary rock stepped tableland in a water divide setting. Sandstone units play a prominent part in the morphology of the massif, acting as cliff formers and supporting extensive plateau levels. High-resolution elevation data acquired from airborne laser scanning allowed us to objectively characterize local relief through selected geomorphometric parameters such as elevation, slope, relief energy, and aspect. In addition, a Topographic Wetness Index was calculated. This constitutes a major advance in relation to the previous, largely qualitative and site-specific observations. In addition, through this detailed geomorphometric approach new facets and features of relief have been revealed and differences between various parts of the massif highlighted. Sandstone escarpments differ in morphology and hence, by inference, in formative processes. Differential retreat by sapping and mass movements is the long-term pathway of geomorphic evolution but along the northern escarpment it seems to have been recently replaced by erosional dissection of plateau rims.
