Item Qualitative assessment of ecosystem services for recreation and tourism in the spatio-temporal geosystem(Видавництво Львівської політехніки, 2023-02-28) Boyko, Taras; Ruda, Maria; Paslavskyi, Mykhailo; Lviv Polytechnic National University; National Forestry University of UkraineThe 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.Item Space-functional role of consortiums of ecotones of protective type to ensure the environmental safety on railway lines(Lviv Polytechnic Publishing House, 2015) Ruda, Maria; Pohrebennyk, Volodymyr; Ukrainian National Forestry University; Lviv Polytechnic National UniversityA multi-factor analysis of the impact of the Lviv Railway transport on the environment takes into account the properties of natural systems: multiple connections, stability, commutability, additivity, invariability as well as multivariable correlation of nature components. One of the important steps towards ensuring environmental safety in the railway transport is the formation of ecologically balanced system of nature management on the basis of environmentally clean technologies. A fundamentally new model of environmental safety in railway transport is of great polyfunctional importance as this enables, on the basis of the landscapeecological methods, to form consortiums of protective ecotones that will provide the maximum spatial-temporal efficacy.
