Positional-dynamic territorial structure of the urban landscape

Abstract

The knowledge of landscapes’ positional - dynamic structure enabled us to include it in the work on urban landscape and ecological planning, with its ownspecifics as environmental management objects. The aim is to create cartographic models of a positional-dynamic territorial structure of Kharkiv landscape to ensure a balanced use of nature in environmental management. Methods: a positional-dynamic structure of urban landscape was selected by compiling andanalyzing cartographic works of landscape strips, tiers and districts. Territorial configuration of different types of landscape strips were identified and established based on the classical scheme of landscape locations typology by water-geochemical regime proposed by B. Polynov and supplemented by M. Glazovska, which includes 9 main types. Technically, synthesis of parameters combinations and determination of the territories affiliation to certain types of landscape strips was carried out using spatial analysis tools (in particular, reclassification and raster calculator) of initial data on morphometric relief parameters in ArcGIS. Results. A set of qualitative parameters is proposed, based on the characteristics of each type of landscape strips by which they can be identified.Composition and territorial configuration of positional-dynamic landscape strips of the urban landscape are established as a result of systematization and processing of geodata parametric features of the water-geochemical regime. Cartographic models of the positional-dynamic structureof Kharkiv landscapes have been developed, including 13 types of landscape strips with individual features united in 5 groups by types of lateral migration of substances due to the peculiarities of their positionality (common position in relation to frame lines of flow directions) and factors of relief morphology similarity, nature of income and intensity of substances transfer. The identified mode types and the nature of the spatial distribution of the corresponding landscape strips have been described in detail. Conclusions. Cartographic models of the positional-dynamic territorial structure of Kharkiv, developed during the inventory stage of landscape-ecological planning, make it possible to choose areas of balanced nature management of a particular area.
