System classification of tourismology: scientific traditions and modern calls

This exploratory article attempts to generalize knowledge and approaches to the understanding of tourism as integrating concepts in scientific discourse on the study and research of tourism as a phenomenon of human life.There are new requirements in the study of theoretical and applied some problems before tourism science, in particular at the level of understanding of tourism as an object of scientific knowledge. The topical theoretical task is to harmonize the understanding and interpretation of tourism science, tourismology, their parts, the improvement of the concept of the separation of object-subject and methodological foundations of scientific disciplines. To solve these and other actual problems, it is necessary to combine the efforts of various sciences and their parts, individual scientists nationally and globally.The article deals with the peculiarities of tourism as a social phenomenon, an object of scientific knowledge and research, an efficient branch of economics, a part of fundamental and applied sciences, and its structure. Each science has its own subject and object of research and is a synthesis of knowledge about the phenomena of reality that it studies. However, it certainly is in certain interrelationships with other sciences. Thus, the methodological functions of tourism and tourismology are considered, such as: integrative, system-forming, structural-functional.Approaches to understanding the essence of tourism, tourism, as the fundamental categories in the scientific sense of the main object of research – tourism are described.Particular attention is paid to the geography of tourism, its place in the system of sciences and individual disciplines, their connection between them and their mutual influence. The basic directions of tourism studies are defined: the philosophy of tourism, the history of tourism, praxeology of tourism, the geography of tourism, cultural studies of tourism. We have identified tourismology and positioned it in the classification scheme over tourism in the context of scientific substantiation and conceptualization of theoretical and practical foundations of tourism studies with all its components.Key words: tourism, tourism science, tourismology, tourism geography, classification.
