Relevant information for the classification of Slovenian landcsapes with geographical information systems is needed. This paper presents two methods for evaluating the importance of digital data to determine the natural landscape types. We evaluated digital data layers according to their relevancy for determination of natural landscape types in Slovenia. To find out which digital data layer (e.g. hihgt, slope) can sufficiently reveal differences among potential Slovenian landscape types, each layer was compared with the map of landscape-ecological types that was produced by group of geographers. We used different methods (e.g. gain ratio, Mann-Whitney U test, Spearman correlation coefficient, decision tree) to select and to test the most appropriate data layers. In this study we analyze the digital data, showing the main natural features of the landscape such as altitude, slope, precipitation regime, temperature, rock type, density of river network and others.
The paper presents some statistical methods that can evaluate certain geographical typification and determine whether landscape types of typification significantly differ depending on the selected data layers of landscape elements. We examined all types of 2 geographical typifications of Slovenia. The older one with 9 types has been determined by using geographic information system only in part, while the later one with 24 types in all.
Slovenian geographical literature often emphasizes Slovenia’s landscape diversity and its position at the intersection of four major European geographical units: the Alps, the Mediterranean, the Pannonian Basin, and the Dinaric Alps. This article establishes whether Slovenia’s diversity is also reflected in non-Slovenian geographical divisions (classifications, typifications, and regionalizations) of Europe. It examines various divisions of Europe and establishes how Slovenia is divided and to what extent these divisions resemble the well-established Slovenian geographical typification of Slovenia.
The main purpose of this analysis is to identify places in Europe that can be described as very diverse according to various natural landscape types or regions. In order to obtain these “hotspots,” several geographical divisions of Europe were examined. The analysis was performed for most of Europe at 5 km resolution. First, maps of landscape variety were produced based on each division of Europe taken into account. This step was carried out for each cell by counting the number of different unique natural landscape types or regions that are present in a radius of 50 km around the cell. Several maps of landscape diversity were produced using this method. Each of them was then weighted; the cell values were divided by the number of all unique types or regions in a division. In the final stage, all of the maps were synthesized (averaged) into one map showing landscape diversity for Europe. With this data it was possible to determine Europe’s landscape hotspots and to define the most naturally heterogeneous countries. Among all of the European countries, Slovenia has the highest average landscape diversity; the highest absolute landscape diversity is located in the Norwegian part of southern Scandinavia.
Several regions extend into the Municipality of Idrija: two European and Slovenian macroregions, four Slovenian mesoregions, as well as numerous microregions. Within the municipality, 17 microregions were defined: ten plateau-like micro regions (the Črni Vrh Plateau, Dole Plateau, Godovič valley system, Krnica Plateau, Ledine Plateau, Ravne Plateau, High Trnovo Forest, Vojsko Plateau, Vrsnik Plateau, and Zavratec Plateau) and seven valley-like microregions (the Idrija Basin, Kanomljica Valley, Sovra Valley, Lower Idrijca Valley, Spodnja Idrija Basin, Zala Valley, and Upper Idrijca Valley).
