Abstract—Six types of soil-geomorphic systems within sulfate-karst landscapes in the north of European Rus-
sia have been investigated. The distinctions in structure and composition of these systems are conditioned by
the tectonic fault pattern and jointing of the karstland. The soil data obtained allow us to gain an insight into the
essence of geomorphic processes and to evaluate the dynamics of land surface in karst landscapes. Conceptual
models of the origin and dynamics of soil-geomorphic systems of karst landscapes and the model of their evo-
lution within the zone of dense jointing of gypsum rocks under the impact of denudation processes are sug-
gested. The assessment of geomorphic functions of the soils in karst area attests to their importance as the con-
trols of potential erosion. Only soil-biotic processes (litter accumulation) are undoubtedly protective, while
other processes may either hinder or strongly intensify the erosion. After the Quaternary sediments are removed
and the erosion starts to penetrate into the hard gypsum layer, a strong positive feedback between soil-forming
and karst-forming processes appears. Thus, the final stages of the evolution of soil-geomorphic systems in karst
landscapes are characterized by great dynamism.
