“…In fact, it was according to Defert's coefficient and rate of tourist functionality that six groups or categories of tourist operative indicators were derived, and these were proposed and used in the ensuing decades as one of the key indicators of spatial and socio-economic tourism identity at various spatial levels (Keogh, 1984;Pearce, 1987;Smith, 1989;Lozato-Giotart, 1992;Potts, Uysal, 1992;Medlik, 1997). Besides this indicator in the analysis of the intensity and encumbrance caused by tourism in a destination, numerous other indicators were used, such as complex indicators of tourism sustainability (Blancas et al, 2010;Torres-Delgado, López Palomeque, 2014), tourist intensity rate, tourist penetration, density and concentration (Lundberg, 1974;de Albuquerque, McElroy, 1992;Harrison, 1992;Verbeke, Spee, 1995;McElroy de Albuquerque, 1998;Matzler et al, 2005;Castellani et al, 2007;Castellani, Sala, 2010) as well as the influence of tourist activity on a locality evaluated via the number of tourist beds in a spatial unit (Dumbrovská, Fialová, 2014).…”
