Pryshchepa A. Theoretical and methodological bases for evaluating the crisis phenomena of agrosphere in the zone of influence of urbosystems

In the dissertation it is carried out the theoretical and methodological substantiation of the estimation of crisis phenomena in the agrosphere of the zone of influence of the urban system with the use of the system approach; it is developed and tested the author’s methodology and methods of research of the agrosphere of the zone of influence of the urban system. The essence and content of the concept of ‘agrosphere of the zone of influence of urban systems’ are clarified. The agrosphere of the zone of influence of the urban system (ZIU), as the object of study, is a multifunctional system that is in constant development with the urban system, and is described by the lack of clear boundaries, sufficiently pronounced spatial organization, and functional structure, which reflects, to some extent, urban and rural features. The methodological scheme of the study includes four sequential logic blocks: 1 – determination of typical preconditions for the origin and formation of the agrosphere of ZIU; 2 – the study of the structural and functional state of the urban system; 3 – the study of the structural and functional state of the agrosphere; 4 – determination of the zone of influence of the urban system on the agrosphere. The author’s conceptual model of research of the agrosphere of the zone of influence of the urban system as a complex socio-economic and ecological system, based on the established structural and functional regularities, conceptual bases of interaction of the urban system with the differentiation of agrosphere and differentiation is developed and tested on the urban system of Rivne and adjacent agrosphere.
