S.V. Galachieva, A. A. Sokolov, O.A. Sokolova, S.A. Makhosheva

The purpose of the work is the development of information support and the structure of an information system in which based on the optimal filling of control data and their further processing, the effectiveness of assessing the sustainable development of regional economic complexes in mountain areas is enhanced. The creation of a structure for the sustainable development assessment system capable of ranking the causes of radical displacement and shifts of regional economic complexes beyond the "cone of admissibility" under which the irreversible changes occur is an actual national economic task. Methods. In the course of the research methods of mathematical modeling, economic analysis, experimental studies and data from the statistical service were used. To solve this problem based on the analysis of the research results, the structure of the system for assessing the sustainable development of regional economic complexes was scientifically substantiated, developed and tested. The developed information support system was based on the method of optimal filling it with information sufficient for analysis and processing working on the basis of the objective function. For processing control data on sustainable development of the region, the information processing method was adapted based on the introduction of individual parameters of the region under study. Results. Approbation of the work of the system for assessing the sustainable development of the region with the software developed at a number of industrial facilities in the Kabardino-Balkaria Republic (CBD) showed that the progressive development of the region is inextricably linked with the expansion of industrial and economic ties with other regions and countries. Therefore, the CBD is facing a radical industrial restructuring not only in connection with the growing demands of the consumer and manufacturing sectors of the domestic market, but in accordance with the requirements and conditions of sustainable development. Conclusions. The application of the system for assessing the sustainable development of the regional economic complexes coupled with the results of thr research and development activities can contribute to the development of scientific, technical and technological potential. The proposed information support makes it possible to assess the sustainable development of regional economic complexes in any regions of the Russian Federation on the basis of the introduction of specific characteristics for the region under investigation, in databases.

Sahakyan E.E., Sargsyan L.S., Babayan H.Y., Gevorgyan M.R.

The Javakheti Volcanic Highland, located in the central Caucasus, is part of the ArabiaEurasia continental collision zone. The area is characterized by active tectonics and volcanism. Features of seismic activity and parameters of seismic regime in the volcanic highland of Javakheti during the period of 2005–2017 were studied in this work. High seismic activity (a=4.44) had been characteristic for the Javakheti Highland during the indicated period. From the Gutenberg-Richter relation, b is equal to 0.8, which means that the seismicity of this area is due to weak earthquakes. The epicenters of earthquakes with ML≥3.0 magnitude are located either along active faults or in areas adjacent to them. The distribution of hypocenters shows that seismic events have mainly occurred up to the depth of 20 km, which coincides with the earthquake depths in the Caucasus. Seismic activity in this source area has been characterized by a staged pattern of more passive phases followed by active ones.

ATMOSPHERIC POLLUTANTS AND HEALTH – GEO-ECOLOGICAL IMPERATIVE OF SUSTAINABLE DEVELOPMENT OF MOUNTAINS OF KARACHAY-CHERKESSIA

E. M. Baichorovа, N. S. Dega, V. V. Onishchenko, S.-B. M. Arikenov

Purpose: to study the influence of technogenic load and anthropogenic impurity in free air on indicators of health of the population with identification of cause and effect dependence, to develop sanitary and hygienic recommendations about improvement of a surrounding medium, strengthening of health of the population in sustainable development of the Karachay-Cherkess Republic. Methods. Methodological approach of air quality research is based on the detailed analysis of structure and seasonal dynamics of pollution on route posts of observation and on padding points of selection of single tests. During the researches sample were drawn in reference points on territories of the republic and the analysis of emissions of pollutants from stationary sources was carried out. On reference points according to state standard specification 17.2.3.01-86 samples of air for definition of dioxide of nitrogen, white damp, ammonia, sulfur dioxide, phenol, formaldehyde and suspended matters were selected. Results (discussion): It is established that the tendency of air impurity concentration accumulation is observed for the free air in KChR expired, more than 15-year period, bulk emission of pollutants in the atmosphere of KChR in an annual cycle increased more than three times (from 19,2 to 58,1 thousand tons/year), at the same time by 2,4 times the common incidence among the population of the republic increased. Indexes of incidence of the period of 1994-1999 significantly differ from that, received by us from 2012 for 2016. The incidence of respiratory organs increased by 1,4 times, nervous system – by 1,8 times. Significantly indicators of diseases and other classes of incidence, narrowness of correlative communications with environmental factors at the same time very high raised. Conclusions. Depending on the prevailing kind of activity in areas of the republic increase in level of the corresponding classes of diseases is noted. At the developed sanitary and epidemiologic and ecological situation in territories of municipal units of Karachay-Cherkessia as shows the geoecological analysis it is possible to expect body height of incidence and abundance of diseases, the bound to increase in anthropogenic impurity in the air environment in the nearest future. At the same time indexes of health will allow to improve evidence-based ecologo-economic, technological and sanitary and hygienic actions for quality management of the air environment due to decrease in intensity of influence of risk factors. This task as it is represented by the authors can be solved by creation of a regional geographic information system.

ALTITUDE-ZONE DIFFERENTIATION OF MOUNTAIN LANDSCAPES: IS COMMON TERMINOLOGY POSSIBLE?

A. Gunya, M. Richter

The study of altitude-zone of mountain landscapes has a rich history. However, the allocation of mountain systems from the general natural structure of the Earth has not yet been ensured by the appropriate methodology, the seeming specificity of mountain landscapes does not have its strict justification and terminology. At the present stage of increasing the importance of mountains in the context of global changes, it is necessary to coordinate research and develop a generally accepted conceptual framework. The russian mountain landscape studies, which have rich methodology and experience, face the danger of being unnoticed in world research. Steps are required for convergence of positions, first according to well-known terms denoting the main altitudinal zones. The simplified schemes of high-altitude zoning in the various geographical belts can serve as a basis for further generalization. It seems that the most universal for different regions of the world can be the four main high-altitude stages that carry the signs of both climate and terrain. First, lowest stage, colline. It is separated from below from landscapes, which are often referred to as "planar". The second stage characterizes typical mountain landscapes (montane). The upper limit of this stage, as a rule, is indicated by the upper limit of forest spread and the upper limit of permanent settlement. The third stage - alpine - follows a higher montane and includes landscapes where it is possible to grow non-forest vegetation. In Russian landscape science, the term “alpine”, as a rule, refers to the designation of the forms of macro relief, as well as to the allocation of alpine meadows as subzones of the high-altitude mountain meadow landscape zone. In this respect, the international definition is broader, since it includes all landscapes above the upper boundary of the forest. In arid areas, where the distribution of forests is limited by natural and climatic factors, the boundary between the second and third stages is not expressed. The use of the terms "alpine" and "subalpine" in the Eastern Caucasus, in the mountains of Central Asia and other arid territories does not always reflect the specificity of local landscapes. Finally, the fourth stage - nival - is the least controversial. It stands out in almost all classifications as a step that completes the entire spectrum of high-altitude landscapes and denotes an area above the upper limit of the distribution of vegetation. In the Russian landscape science, it corresponds to the nivalglacial type of landscapes.

TO THE QUESTION OF THE EFFICIENT RESOURCES USE IN THE MAPLE FORESTS TYPE OF THE CAUCASUS

Kh.M. Khetagurov, A.V. Gryazkin, M.M. Gutal, P.A. Feklistov

The aim of the study was to assess the resources of the Caucasus high – mountain maples for forest planning and efficient use. The high-mountain maple Acer trautvetteri Medw., remains little studied among forest-forming species and features of the structure of stands stocks and properties of wood, plant raw materials, non-wood products have not yet been studied. In the Caucasus high-mountain maples occupy the Northern slopes of the ridges at altitudes from 1 to 2,2 thousand m. The structure of high-mountain maples, stocks and structure of raw materials deposited in these plant communities depends on the height above sea level. Based on the results obtained, the zone of distribution of the Trautfetter maple along the vertical profile is conditionally divided into three zones: the upper belt (above 1600 m above sea level), the middle belt (from 1301 to 1600 m above sea level) and the lower belt (up to 1300 m above sea level). It is established that high-mountain maples are a source of various medicinal and technical raw materials of a vegetable origin, food plants, good base for beekeeping. The greatest number of useful for human species of plants is concentrated in the lower tiers of high-altitude maple trees. Most of the types presented here are polyresource ones. Resource plant species are represented by the main life forms-trees, shrubs, herbaceous plants, semi-shrubs and shrubs. The most represented in klenovnik are herbaceous plants, semi-shrubs and shrubs. To food plants include more than 50 species, 69 species of medicinal, melliferous 73, to technical plants 61 views. It is established that the majority of resource species do not form continuous thickets, the projective cover on a particular forest area is most often about 5 %. This makes it impossible to organize the use of a certain list of resource species on an industrial scale. On the other hand, with a yield and reserves, allowable current rules and regulations, procurement polyresource types feasible and economically justified. At each forest site, regardless of soil and groundwater conditions at the same time grow to dozens of resource species of plants. In this regard, the procurement of food and medicinal raw materials in separate tracts is possible. Stocks and yields of a particular type of plant in a particular forest area is determined primarily by forest growth conditions, which primarily depend on the height above sea level and other elements of the relief. As the height above sea level increases, the number of resource species is changing towards their decreasing. Changes not only the number of species, but also stocks of raw materials, the yield of individual species. The distribution of the species also depends on a variety of other factors: exposure and slope steepness, composition, height, density of the tree stand, closed treeshrub canopy, etc. In order to preserve the mountain forests and high-mountain maples in particular, it is necessary to study their features and structure, establish the types of resources, stocks and yields. Effective management of mountain forests will allow to implement the tasks of their use and increase their environmental, soil protection, raw materials and other functions.

EVALUATION OF USE OF EFFECTIVE TECHNOLOGIES FOR INCREASING SUSTAINABLE DEVELOPMENT OF NATURAL AND TECHNICAL SYSTEM OF OIL AND GAS COMPLEX

E.V. Yegorova, R.V. Klyuev, I.I. Bosikov, B.S. Tsidaev

Introduction. The increase in the production of hydrogen sulfide-containing gas in the Astrakhan field is an extremely urgent and promising task. Based on the current reserves of the field, the level of extraction of raw materials can be increased by 3-5 times relative to what has been achieved. One of the promising technologies that allows to significantly increase the extraction of hydrogen sulphide-containing raw materials when solving the problem of overproduction of sulfur and preservation of environmental requirements is the technology of injecting acid gases into underground layers. The aim of the research is to evaluate the efficiency of the use of new technologies at the Astrakhan gas condensate field. Research tasks. The tasks are solved on the basis of a comprehensive study of effective technologies for enhancing the sustainable development of the technical system of the oil and gas complex. Materials and methods of research. One of the main directions of pilot industrial works at the injection site is connected with the operation of injection wells, determination of the main parameters of their operation, design reliability and hydrodynamic characteristics of the reservoir and tubing. When creating a landfill, it is possible, both the construction of a new well, and the use of a well of an existing fund. Considering the fact that drilling a new well is associated with significant time and financial costs, in the context of this work a decision was made to use a well from an existing fund. As the injection well, the well was chosen according to the set of basic geological-technical and technological indicators: the lowest current reservoir pressure; the least working wellhead pressure; The presence of formation water in the production of the well; average values of productivity; good values of reservoir properties; good technical condition; proximity to the existing capacities of the Astrakhan gas processing plant. The formalized model of the injection well operation includes two main interconnected elements - the flow of the injected agent through the well tubing and the bottomhole formation zone. Acid gas, obtained in the desulfurization plants of highpressure gas, is used for pumping into the productive stratum as part of pilot-industrial tests of the new technology. The most preferable scheme is the organization of an experimental test site, in which the preparation of acid gas (its compression, drying and transfer to a single-phase liquid state) is carried out near or directly at the site of the enterprise. Next, a liquid stream of acidic components is transported through a pipeline to the landfill where a pumping station is installed to supply fluid at the mouth of the injection well with the pressure required for injection. The developed technology of preparation of acid gases for injection into the reservoir in the Astrakhan arch includes the following technological operations: compression of acid gas in 4 stages; interstage cooling of the stream, separation and discharge of the discharged liquid; drying of the flow of acid gases with a pressure of 3.5 MPa and a water content of 0.5-0.6% by volume. after the fourth stage of compressioncooling by a solution of triethylene glycol to a residual water content of not more than 0.01% by weight. Results. The project of sour gas injection technology has been implemented, which aims at the use of waste tanks and is characterized by relatively low productivity and low injection pressure at the wellheads. The project is designed for specific conditions, for which a large array of information is created. Before taking a decision on the large-scale introduction of technology at the Astrakhan gas condensate field, an experiment was conducted at the experimental industrial site, reliable baseline data was obtained that could economically and with minimum risk realize the technology of acid gas injection into selected objects

POWER TRANSMISSION LINES WITH A REDUCED NUMBER OF WIRES IN MOUNTAIN TERRITORIES

N.S. Buryanina, Yu.F. Korolyuk, E.I. Maleeva, E.V. Lesnykh

Goal. In this paper a study of power transmission lines operating in the "Two wires-to-ground" (DWS) mode, as well as four-phase lines (CHLEP) was made which were first mentioned in the 50s of the last century. These lines have greater bandwidth and reliability. To confirm the above results comparison with three-phase systems was carried out and the dependence on power losses on the lines regimes was determined. Methods. The research was carried out with the help of mathematical modeling. The algorithm and complex of the software solution with the help of the Mathcad system are compiled. Basis of constructing a mathematical model – is the canonical form of the method of nodal stresses, all elements of the network are decomposed into symmetric components. This algorithm is universal and can serve to calculate the parameters of a three-phase network with the number of nodes up to 400 in different modes of operation. Results and its discussion. It is shown that the DPZ lines have lower than other losses, the greater the transmitted power and the length of the lines. Thus, the efficiency of the system directly depends on the length of the air line. The modes of operation of four-phase power lines including fivewire lines are considered. Conclusions. The use of two-wire-to-ground transmission lines under current conditions is economically feasible due to significant losses in them as compared to three-wire lines at a voltage of 6-35 kV. The current reduction in the earth is possible with the use of four-phase power transmission lines consisting of two DPZ, in which the voltages on the same phases are opposite in direction. With the same loads, both circuits in the ground are absent, therefore, there is No power loss in the grounded phases. The introduction of an additional wire improves the reliability of a four-phase line to the reliability of a two-circuit three-phase line. By reducing the number of line wires in the proposed electrical system in comparison with two-chain three-phase line the electric energy and voltage losses are reduced, decreasing the cost due to the lower expenditures on line construction(five wires instead of six).
