摘要：Biosphere reserves are protected areas vital for the preservation of living and inanimate nature, including the protection of anthropogenic values and cultural heritage. The basins of the Mura, Drava, and Danube rivers stretch through Slovenia, Croatia, Austria, Hungary, and Serbia and form a unique spatial unity. The Biosphere Reserve concept defines about 300,000 hectares of core and buffer zones and around 700,000 hectares of transition zones. This large, primarily marshy area is rich in natural and cultural heritage. This area is called “the Amazon of Europe” and represents the world’s first Transboundary UNESCO Biosphere Reserve, “Mura-Drava-Danube,” among five countries. This biosphere reserve is important for the preservation of the natural and cultural values of the entire region. Especially rare plant and animal representatives live in this unique geographical unity. Some species inhabit only this area. A total of 900,000 people living around this reserve have a rich cultural tradition and heritage that needs to be protected. The objective of the research is to examine the function that the selected protected areas have in the sustainable development of tourism. Quantitative methodology was used in the research. An analysis of the conducted questionnaire was performed using the SPSS v.21 software, as well as a comparative analysis of the attitudes of 1295 residents from three countries. Residents’ attitudes refer to the level of ecological, economic, socio-cultural, and institutional sustainability of this biosphere reserve as a tourist destination. The research results indicate that the four dimensions of sustainability have significant values and that the selected areas have an important function in the sustainable development of tourism.
