Abstract
Geodiversity is represented by the uniformity of physical properties of the earth and is considered an important landscape feature in its assessment. Due to the multitude of identified abiotic physical elements (66 elements) in the mountain area of Moldova catchment, the geodiversity index was computed, ranging from 0.30 to 8.72. The area with the largest number of elements overlaps on Câmpulung Moldovenesc with 12 identified abiotic elements, followed by Pojorâta, Moldova – Sulița, Breaza and Fundu Moldovei with values of the geodiversity index above 2. These localities form a compact area that should be considered in future conservation and promotion strategies.
Highlights
The concept of geodiversity is a relatively recent concept, proposed by geologists and geomorphologists, which was first used in the early 1990s as a tool in protected area management to describe the variety from abiotic nature (Gray, 2004; Serrano and RuizFlaño, 2007)
For the communes whose surface area did not fully fall within the perimeter of the studied hydrographic basin, only the surface that overlaps the study area was taken into account in the calculation of the geodiversity index
The highest values of the geodiversity index characterize the upstream area within the catchment, located in the north-east
Summary
The concept of geodiversity is a relatively recent concept, proposed by geologists and geomorphologists, which was first used in the early 1990s as a tool in protected area management to describe the variety from abiotic nature (Gray, 2004; Serrano and RuizFlaño, 2007). In analyzing the geodiversity of a particular landscape, a number of abiotic natural factors are considered, such as rock types, landforms, hydrograhic network, soils and geomorphological processes. By analyzing these factors and their interactions, the areas with a major geodiversity index can be identified (Manosso and Nόbrega, 2016). Sharples (1995) defines geodiversity by the variety of solid rock types, geomorphological characteristics, soil types and the set of systems and processes in a given area
