Polazište za istraživanje ovoga rada je u širokom spektru metoda kojima se mogu vrednovati krajobrazne kvalitete. Svrha rada je utvrđivanje prednosti i nedostataka često korištenih pristupa za vrednovanje krajobraza. Na odabranom području istraživanja, otoku Rabu, radom je identificirano petnaest krajobraznih područja te su određena tri pristupa za vrednovanje kvaliteta krajobraza: 1. jedan temeljen isključivo na vrednovanju ranjivosti kvaliteta krajobraza, a dva na procjeni osjetljivosti krajobraza; 2. preklapanjem krajobraznih područja sa združenim modelom ranjivosti kvaliteta krajobraza i 3. izravnim vrednovanjem krajobraznih područja s prirodnog, kulturno-povijesnog i vizualno-doživljajnog aspekta. Navedeni pristupi međusobno su uspoređeni radi utvrđivanja sličnosti i razlika među njima, kao i ukazivanja na prednosti i nedostatke svakog od njih. Rezultati su pokazali da adekvatnost pristupa ovisi o odabiru homogene prostorne jedinice. Ispravni pristup odabiru kriterija vrednovanja može utjecati na objektivnost metode. Najviše kvalitete krajobraza utvrđene su na jednakim područjima neovisno o pristupu utvrđivanja navedenih kvaliteta.

The paper is based on a review of the established principles for evaluating the natural qualities of landscapes and developing procedures that can contribute to current methods, upgraded with indicators derived from the perception and attitudes of the public. They were implemented into an integrated model of natural landscape qualities. The method included modeling of the natural landscape qualities for the southern part of the Krka National Park in Croatia. The first evaluation model was based on a survey whose responses were processed and classified using the AHP method and GIS. The results showed that the respondents recognize the diversity of land cover and relief forms and the degree of their fragmentation as the highest natural landscape quality. The second step included overlapping the vulnerability model of natural landscape qualities and the model of perception of natural qualities. It was found that the implementation of perceived natural qualities in the evaluation process affects the model of vulnerability of landscape quality. It also indicates the possibility of implementing the perceived natural qualities of certain landscape types into the complete landscape evaluation process, which encompasses all values in the space, including human perception. Therefore, the whole procedure pointed out the importance of the implementation of perceived values into landscape evaluation, something which is also emphasized by the European Landscape Convention (ELC).

This paper aims to present an approach to landscape evaluation, on the example of the island of Jakljan, which is a part of the Elaphiti Islands in the Dubrovnik Neretva County. Special emphasis is placed on the evaluation of natural, cultural, and visual qualities, which were identified in order to direct their protection in future development processes taking into account their role in the landscape. After determining the main qualities, the submodels of individual landscape qualities were determined. Next, the relationship between landscape quality and potential quality degradation was analysed, and a database of spatial data was prepared. Natural qualities included biodiversity valuation and perception of naturalness of the most dominant landscape patterns in this area. Cultural qualities included agricultural landscape evaluation and cultural-historic heritage. Finally, based on the evaluation of the visual units and visually attractive and authentic elements of the landscape and the analysis of visual exposure, a final model of visual landscape qualities was carried out. Evaluation maps were obtained using the GIS tools. The paper pointed out the most important values which must not be lost if the existing character of the space is to be preserved.

The incentive for this research has come from a wide range of methods for landscape quality evaluation. The purpose was to determine the advantages and disadvantages of the commonly used approaches for identifying landscape values. In the selected research area, the Island of Rab, the paper has identified 15 landscape character areas and appropriate approaches that were tested to determine landscape values - vulnerability modelling and landscape sensitivity assessment. The results have shown that the adequacy of the approach depends on the selection of a homogeneous spatial unit; the appropriate approach for the evaluation criteria selection may affect the objectivity of the method; and the highest landscape qualities were determined in the same areas regardless of the used approach.
