The paper proposes a comprehensive method of qualitative evaluation of services provided by
various providers, which are expressed by characteristics that avoid a quantitative representation. The research
foresees the application of the well-known method of deployment of quality functions, the development of which
consists of the possibility of determining the coefficients of the weighting of technical characteristics of cultural
ecosystem services for recreation and tourism of the spatiotemporal geosystem. To take into account the priority of
consumer requirements, the expert method of pairwise comparisons was introduced, which was modified so that
possible conclusions could be considered, in particular, the evaluation of the equivalence of characteristics was
applied. To obtain the degree of correlation between the characteristics determined by experts based on consumer
requirements and the technical characteristics of cultural ecosystem services for recreation and tourism, it is proposed
to utilize the fuzzy logic method. Since both the presence of correlations links and the degree of correlation between
consumer requirements and technical characteristics are the result of the interaction of a set of various factors, among
which a significant number may be random, based on the central limit theorem, as well as the experience of applying
correlation coefficients in other areas, a conclusion is drawn, that the probability distribution function of correlation
degrees is properly described by a Gaussian curve. The value of the technical characteristics of the specified
ecosystem services for three spatiotemporal geosystems was also obtained with the help of the fuzzy logic method.
