Principles of urbanized territories identification and indicators of their sustainable development

The term "urbanized territories" is relatively new in the domestic literature, so there is no certainty in their identification. The purpose of this study is to determine the principles for identifying them, establishing indicators of sustainable development. When writing the article, methods of analysis and synthesis as well as statistical ones were used. At studying, it was proved that all categories of land can be attributed to urbanized territories. The main results were the establishment of the basic principles for identifying urban areas, calculation of the Tyumen region territory spatial development indicators, and those of sustainable development. The authors propose a qualitatively new approach to determining the essence of urbanized areas, which will help scientific communities in carrying out further research in this locality.
