Application of the catena concept in studies of landscape system dynamics

Abstract

The concept of catena in landscape surveys is used to demonstrate the surroundings of landscape units, their vertical structure and inter-unit processes, as well as the mosaic nature of the landscape. Furthermore, it reflects the structural and functional heterogeneity of the surveyed area, at the same time indicating types of links between landscape units, depending on a variety of geological, habitat-related and biotic conditions, including land use and its transformation arising from anthropopressure. The catena survey performed included four key morphological and lithological units with varied landscape structure and functioning: glacial upland, vast outwash plains, the Wisła River valley and deepened channel valleys, as well as dune hills and hillocks. The results prove that the functioning of landscape systems depends on the forms of land use and their durability. Characteristics of leading components in catenas are diverse despite a similar genesis of landforms and relief shaping processes.

Microtopographic variations in soil physico‐chemical properties in oldfield targeted for ecological restoration

“…The above-mentioned study showed that soil properties are highly correlated with slope position (Karaca et al, 2018). Soil organic matter content has been reported to vary based on slope position, this likely a result of the catena concept which suggests that downhill movement of plant material due to gravity and water flow results in different soil characteristics between the hill summit and foothill (Malinowska & Szumacher, 2013).…”

Therefore, there is a need for in‐depth understanding of how slope position shapes soil physico‐chemical properties and how these influence soil and vegetation recovery in oldfields targeted for ecological restoration.…”
