The prospects of a model exposition in artificial plantations in urbanized territories

Abstract

The main tasks of the ecological potential are to unite the disparate existing elements of plantings and supplement them with new ones. The assimilation of unique plant ecosystems is possible with an integrated approach. The Volgograd region belongs to the dry-steppe zone, the climate is sharply continental, for which the characteristic features are a decrease in natural moisture supply, excess heat, an active wind regime throughout the year and frequent dry winds. The ecological potential of the south of Russia, in particular the Volgograd region, according to the climate Biological efficiency Index (TC) proposed by N.N. Ivanov, is at a low level (TC = 8–12) with unfavorable natural living conditions of the population with a significant lack of moisture, which raises the question of creating multifunctional plantings as a research scientific basis for rational regional environmental policy in optimizing the process of settlement and social sphere, consistent organization of work and recreation, protection of citizensʼ health. Dendrological expositions growing on cadastral plots of the Federal Research Center for Agroecology of the Russian Academy of Sciences have a high ecological potential in urbanized territories.The purpose of the study is to evaluate the prospects of a model exposure of drought–resistant species in artificial plantings.A general analysis of the decorativeness of G Gleditsia triacanthos f. inermis, Rosa canina, Ribes aureum, Ligustrum vulgare, Juniperus sabina was carried out, the variability of the total assessment of decorativeness between species (34.2–36.6) and the total score (177) were established. All the studied species have good drought resistance, which helps the woody plant to use water and nutrients most efficiently in arid regions on chestnut soils with low moisture supply.
