title: Nodal elements of regional support frameworks for settlement.
abstract: "The author extends his earlier work on the concept of a support framework for settlement (i.e., interconnected linear and nodal elements supporting the activities and needs of population within the settlement system), developed initially for the Caucasus region, to the entire country. A five-level hierarchy of urban nodes, ranging from highly developed agglomerations to small and medium-sized cities, is proposed which is used to analyze the level of urban support provided in the major economic regions of the USSR."
