CITIES AND THEIR ENSEMBLES AS CENTERS OF GEOTORIAL ORGANIZATION IN THE WESTERN REGION OF UKRAINE

Abstract

The state of research on the topic is studied. The concept of a nest of geospatial organization and related concepts (ensemble, solo, duet, trio, quartet) are proposed. Considered modeling of a number of concepts (nest, kernel, geoplace, city, city functions). Nests are studied in the context of the concept of geospatial organization of society. The existing classifications of the hierarchical geospatial organization of territorial complexes are considered. Based on this experience, a two-dimensional classification of nests was developed – by the number of cities in the nest kernel and by the number of external transport connections of the nest. This two-dimensional classification is placed in a table whose rows correspond to the number of core cities (one or more) and columns correspond to the number of external connections (zero or more). This table takes into account that, in practice, nest cores have no more than nine external connections. As a result, a "periodic system" of classes of nests of geospatial organization is obtained. The topologies of the largest solo nests of the geo-regional organization in the Western region of Ukraine were considered: a nine-level nest with a center in the city of Lviv, an eight-level nest with a center in the city of Chernivtsi, a seven-level nest with a center in the city of Ternopil, six-level nests with centers in the cities of Lutsk, Rivne, Kovel, Kamianets-Podilskyi, Starokostyantyniv. The topology of duet nests was considered: Ostrog-Netishyn, Brody-Radyvyliv, Radekhiv-Lopatyn, Dobromil-Khyriv. The topology of trio nests: Chervonograd-Sokal-Zhvirka, Volodymyr-Novovolynsk-Ivanichi, as well as quartet nests: Drohobych-Borislav-Truskavets-Stebnyk was considered. All the nests of the geo-territorial organization in the Western region of Ukraine have been worked out and placed in the periodic table according to the two-dimensional classification. The numerical distribution of nests of geo-regional organization in the Western region of Ukraine by the number of external connections was studied and a mathematical model of this distribution was constructed. The conclusions of the modeling of classes of nests were made.
