Abstract

The author’s definition of marginal territories is based on the principle of their uniqueness, specificity, and isolation. Marginal territories mean closed border areas located on the edge of districts or isolated areas in the center under the influence of factors and released a higher diversity and number of species, characterized by isolation from the center, which are based on the isolation of life of the population of the district. The assessment of the quality of the environment for the comfort of living in marginal territories was carried out in comparison with the control areas related to the lands of localities and recreational territories. It is carried out on the basis of a comprehensive analysis of the habitat of groups of organisms sensitive to environmental degradation, belonging to the department of Lichens. The assessment of the condition of marginal territories was carried out by methods of determining the degree of lichen cover and the air pollution level parameter, the biotic index parameter, and the poleo-tolerance index in comparison with control territories related to the lands of settlements and recreational territories.

Highlights

The definition and classification of marginal territories is based on the principle of uniqueness, specificity, and isolation of districts and regions
We can say that marginal zones are located in the following territories: a - peripheral marginal lands; b - located in the middle of the second center and border territories; c marginal lands inside the country - partially isolated territories located around the fourth by the size, localities, but for some reason
Based on the principle of national economic inexpediency of land use, Lipets Y.G. notes [6] that marginal lands are zones, the average harvest, that allows only to cover the costs of production, but it is not enough to pay rent [7]

Summary

Introduction

The definition and classification of marginal territories is based on the principle of uniqueness, specificity, and isolation of districts and regions. Based on the principle of national economic inexpediency of land use, Lipets Y.G. notes [6] that marginal lands are zones, the average harvest, that allows only to cover the costs of production, but it is not enough to pay rent [7]. Based on the principles of economic profitability, location of territories and various numbers of representatives, the paper “Agro Basket” gives the following definitions of the concept of marginal — 1) located on the edge; 2) closest to the limit, almost unprofitable; 3) represents a minority, as an example, marginal vegetation, marginal elements of society [8].
