ANALYSIS OF ECOLOGICAL SUSTAINABILITY AND REGIONAL TERRITORY STABILITY ON THE EXAMPLE OF ORENBURG REGION ^{[№ 4 ' 2017]}
Abstract. Justification of ecosystem sustainability and its ecological stability is one of the urgent problems of our time the solution of which will allow us to develop methods of environmentally safe and harmonious development of the region. Definition of ecosystem sustainability is based on the ratio of territories under the elements of favorable and negative impacts. The heterogeneity of the influence and the ecological significance of each biotechnical element are taken into account in the determining of the stability. The assessment of these parameters is based on the landscape elements identification and their subdivision into predetermined categories in accordance with the structural distribution of the land fund. The main categories include forest, agricultural, settlements, industrial, natural conservation, stock and water lands. Their share on the territory of Orenburg region is 88.5, 5.2, 3.2, 2.1, 0.6, 0.25, 0.15 % respectively. Agricultural land is divided into arable land (55.9 %), fodder land (43.5 %), perennial plantations (0.6 %). Analysis of land distribution allowed us to define time area changes of separate categories and the degree of influence on environment sustainability and territory stability. The maximum stability value is 0.79 when the optimum is at least 1. The stability coefficient is 0.36 and it is 29.5 % below the minimum rate. A number of discrepancies has been identified in the relation to maximum ecological parameters: a large area of agricultural lands (88.5 % with the rate for the steppe zone 60–65 % and optimum 40 %), a high level of plowing (more than 50 % at the rate 40–45 %), extremely low part of the forest fund (5.16 % at the rate 10–15 % and the optimum 15–20 %) and a shortage of natural systems in area land composition in general (SPNT 0.19–0.64 %). The obtained results indicate the violation of ecological system sustainability limit and low level territory stability. The solution of the problem is the introduction of environmental zoning system that makes possible to differentiate the approach to load reduction on the Orenburg region land fund.

THE ROLE OF THE MACRO-CLIMATIC FACTORS IN THE FORMATION OF PLANTS' ADAPTIVE POTENTIAL ^{[№ 9 ' 2016]}
Methods of empirical ecological niches modeling are used extensively in order to predict plant's adaptive potential in unusual conditions. This approach has become almost universal. Nevertheless, it has disadvantages: the species' valence forecast based only on the macro-parameters, the action of biotic and micro-climatic factors and the adaptive capacity of species are not usually considered. Therefore, further study of the unaccounted factor's role is required. The aim of the work is to investigate the separate contribution of macroclimatic and usually unaccounted factors of natural habitats into predetermination of plant's adaptive capacity in unusual conditions (in greenhouses). The objects of the study were 18 species of Ficus L. genus from the collection of the Donetsk Botanical Garden. Assessing the contribution of different factors into determining of adaptive capacities was carried out basing on machine learning methods. Predictors in models were macroclimate indicators of species natural habitats. The dependent variable was the plant's acclimatization success index in greenhouses conditions. According to the results, the adaptive capacity of plants in the greenhouse complex depends on the macro-environment of their natural habitats. The temperature and the precipitation in the range of natural habitats showed the strongest connection with the adaptability of species. The macroclimatic factors account for at least 57 % of the explained variation in the species' acclimatization success. The remaining 43 % of the variation is due to the influence of unaccounted factors. A significant role of usually bypassed factors must be considered during the extrapolation of the niche model's results.

RATIONALE FOR ENVIRONMENTAL TASK OF REORGANIZATION PROTECTIVE PLANTATIONS ORENBURG ^{[№ 10 ' 2015]}
High levels of air pollution in urban areas necessitates the development of more detailed recommendations on the formation of the list of plants with high levels of stability and the main types of getter capacity for landscaping streets and everything SPZ of industrial enterprises in Orenburg, which allows better protection of the population. On the ability to getter gas resistance and investigated 50 kinds of trees and shrubs of Orenburg presented by both local and introduced species. To determine how gas resistance and the ability to apply the methodology getter pilot fumigation with sulfur dioxide. Analysis of the data on all types of stability allowed to isolate from the list of species studied unstable plants, as well as develop recommendations for optimum species composition of green space for the organization of sanitary-protection zones of enterprises and other types of shelterbelts.
