Introduction. The relevance of this publication is associated with the problem of foundation and developing a raw material base of phosphate raw material in accordance with the demand of the national agro-industrial complex. The purpose of the publication is to develop a preliminary digital structural-lithological model (DSLM) of the Kopytkivsky deposit, as a tool for information support of its development, as well as geological and genetic characteristics of the object as a basis for specifying the criteria for predicting deposits of this type. This goal covers the following tasks: - presentation of methodology and research methods; - presentation of the database; - demonstration of derivatives of the created digital structural-lithological model (DSLM) and their interpretation;- representation of functional and cognitive characteristics of the object (Kopytkivsky phosphorite deposit). Materials and Metodology. The studies are based on two methodological principles: traditional lithological, paleofacial, paleogeographic studies and the author's development - digital structural and lithological modeling, dialectically combined in the form of a single predictive-paleoreconstructive retrospective-static model. Main Results. Kopytkivsky deposit belongs to the Zdolbunovskiy district of the Zdolbunovskiy-Ternopil zone of the Volyn-Podolsk Cretaceous basin of the phosphorite-bearing province of the East European platform. The indicated zone refers to the Volyno-Podilllya plate, i.e the western slope of the Ukrainian shield. In the area of the Kopytkivsky deposit, layers of inoceramic limestones represent the lower stratigraphic subdivision of the Cretaceous system, lying directly on the pre-Mesozoic basement. The DSLM of the Kopytkivsky field has been developed, intended for information support for further work on its development (detailed exploration and operation). The DSLM database is represented by a description of 567 geological exploration wells. Conclusions. Based on the constructed DSLM, a number of derivatives (including visualizations) were obtained that reflect the structural and material - industrial characteristics of the field - a number of maps, profiles, as well as a block diagram of the central part of the field. The description of the most informative visualizations are given: Map of the hypsometry of the bottom of the "productive horizon", Map of the hypsometry of the roof of the "productive horizon", Map of specific reserves and others. The model derivatives reflect the spatial (areal and hypsometric) configuration of phosphorites ore bodies and the distribution of specific reserves of P2O5. Based on the methodological principles of formation analysis and the methodological approaches adopted by us for predictive-paleoreconstructive retrospective-static modeling of the object, a geological and genetic characteristic of the stage of formation of layers of inoceramic limestones has been obtained.

Problem formulation. Study and interpretation of geochemical characteristic, component composition, content of macro- and microelements in peat has both a general scientific fundamental character and an applied one. Its results used for various purposes: quality assessment of peat, determination of the possibility of their use in industry etc. The article is devoted to study of the elements and microelements distribution in the peat of the Lviv region. The study of peatlands in western Ukraine and their component composition carried out only during geological exploration aimed at assessing the regions potential to produce own peat fertilizers or fuel. Article purpose. The aim of the work is to present an extended geochemical characteristic of Lviv’s region peats, to determine peats typical microelement composition and geochemical specialization, to establish regional regularities of distribution and accumulation of elements using methods of mathematical and statistical analysis, and to study the factors controlling the content, distribution and genesis of microelements in the region peatlands. Object, subject, factual material and research methods. The object of research is peat and its ash from peatlands of the Lviv region. The subject of research is geochemical characteristic of this peat, regional patterns of distribution and accumulation of chemical elements, components and geological and geochemical indicators in peats. The ashes of 248 peat samples taken in 110 representative areas were analyzed by spectral semi-quantitative analysis for the content of 21 chemical elements and other geochemical characteristics of peat (pH, ash content, etc.). Discussion. An integrated approach to the study of the geochemical characteristics of peat made it possible to identify the spatial geochemical features of peats in the territory of the Lviv region, to determine their typical microelements composition, to establish regional regularities of their distribution and accumulation (changes) - significant unevenness of the concentration of microelements by area of distribution, high indicators of the content of Mo, Yt, Sr, Co, Ag, Ba, Be, Pb in relation to the clarks of the lithosphere, soils, and plants. According to the results of correlation, factor and cluster analyzes, the following typomorphic geochemical associations of peats of the Lviv region can be distinguished: Ti-Ga-Cu-Y-Pb-Sc-V-Yb-Be is associated with the features of natural soil-forming processes of geochemical landscapes; Ni-Mo-Zn is possibly of technogenic origin and is associated with the accumulation of heavy metals in soils due to the development of mineral deposits. Conclusion. The analysis of the spatial distribution, mathematical and statistical processing of the geochemical characteristics and the composition and given varimax factor features and other integral and single-component parameters of peats described in the study indicates their satisfactory condition and can be to co

Formulation of the problem. In today’s age of globalization, the urgent task of socio-economic development is to mobilize the potential of regions to ensure sustainable economic growth within an innovative, socially-oriented development model. Territories are one of the main principles of state development. Decree of the President of the Republic of Uzbekistan No. 60 of January 28, 2022 "On the Development Strategy of the New Uzbekistan for 2022-2026" is particularly important with a focus on optimizing the current environmental situation and public health. Analysis of recent research and publications. In developing countries, the share of industrial production is higher than that of agriculture. Uzbekistan belongs to the classification of developing countries, with a relatively high share of industrial clusters and technology parks in the administrative unit. If we pay attention to the analytical data, the gross domestic product of the Republic in 2017 amounted to 317 476.4 billion soums, in 2019 - 529 391.4 billion soums, and in 2020 - This figure amounted to 605,551.3 billion soums. The share of industry in GDP is 23.5%, 31.4% and 36%, respectively. The aim of the work. Although the Navoi region is considered the smallest administrative unit of our republic, it stands out among the regions in terms of industry and production with huge natural resources. This in itself is the basis for the formation of a negative ecological environment and the emergence of problems related to the health of the population, and from this point of view, the Navoi region and its administrative units were chosen as the object of research. The presence of administrative units with a high share of industry in the country, such as Tashkent, Fergana, Andijan, Samarkand, Navoi, Kashkadarya, has a serious impact not only on the region but also throughout the country. Clearly, local, regional and international cooperation is key to preventing environmental crises, as is the case around the world. If we take the Navoi region alone, it will provide 18% of the republic's industrial output in 2020 alone, which is the third-largest among the administrative units. But there is another side to the issue, and today the ecological environment in urbanized and highly industrialized cities is deteriorating significantly. As one problem raises another, environmental crisis has a serious impact on the health of the people living in the area, which in turn has an impact on living standards and life expectancy. Research methods. This article uses methods such as comparative analysis and comparison, and direct observation based on the statistical data of the Republic of Uzbekistan. Problems of further research. As a result of the harmonious growth of industry and production, problems related to the environmental condition of cities and the health of the population are becoming widespread.

Formulation of the problem. The incorporation of any reclamation system into the existing landscape complexes leads to increased contrast of environments and activation of material-energy-information flows. The construction of the reclamation system in the basin of the Trubizh River radically changed the landscape structure of the riverbed and floodplain, which led to a significant impact on the adjacent landscape complexes. Trubizh water management landscape-technical system goes beyond one river valley, so ill-considered economic activity can lead to deterioration of the ecological condition of adjacent landscape complexes. The study of anthropogenic paradynamic connections between different landscape structures will provide a better understanding of the functioning of the Trubizh water management landscape-technical system and the peculiarities of interaction with adjacent landscapes, which, in turn, will predict its further development and develop ways of rational use. Purpose. The purpose of the article is to study the Trubizh water management landscape-technical system as an anthropogenic paradynamic system. Methods. The process of transformation of natural paradynamic connections into anthropogenic and formation of anthropogenic paradynamic landscape complexes with the help of databases of GIS packages SAS.Planet.Release and GoogleEarthPro is analyzed. The research was conducted using the following methods: system analysis, generalization, comparative-geographical, final results, cartographic, GIS-method. To analyze anthropogenic paradynamic landscape complexes and anthropogenic paradynamic connections between them, GIS packages were used, with the help of databases the process of restructuring of natural paradynamic connections into anthropogenic and formation of anthropogenic paradynamic landscape complexes was analyzed. Results. Because the Trubizh water management landscape-technical system extends beyond one river valley (covering floodplain, floodplain terrace and slope types of areas), it unites the entire river basin into a single whole with the help of anthropogenic paradynamic connections. This poses a threat to the environment, as ill-considered economic activities can lead to the deterioration of the ecological condition of landscape complexes both within one basin and have a negative impact on adjacent basins. Factors in the functioning of paradynamic connections are due to the presence of external and internal links, contrast and spatial dependence between the interacting landscapes complexes. External anthropogenic paradynamic connections include: thermal – the effect of solar radiation on the landscape; mechanical – gravitational influence of watersheds on the low-lying channel-floodplain complex; aquatic – the influence of surface and groundwater on the supply of rivers and the chemical composition of water; social – the impact of economic activity. The internal anthropogenic paradynamic connections include: biocosnic

The presented article is devoted to the study of modern trends in the spread of ice deposits on the territory of Ukraine in the last thirty years of 1991-2020 (new climate standard) relative to the period 1981-2010. recommended by WMO. The conducted research is related to the research work on the study of climate change carried out at the UkrSMI. Question status. Despite certain achievements in the study of the distribution of ice-frost deposits in the territory of Ukraine in the past, the task of determining the existing trends and subsequent changes in their distribution under the influence of climate change remains unresolved. The purpose of the study was to determine the current state and features of the distribution of the field of ice deposits on the territory of Ukraine with the identification of centers of increase and decrease in the average amount of such deposits, as well as trends relative to another observation period. Materials and methods. Data of actual instrumental observations of ice deposits at all meteorological stations of Ukraine for two periods 1991-2020 and 1981-2010 were used for processing. The main research methods were physical-statistical with the determination of the normalized values of the number of cases of such deposits and cartographic with the visualization of the results. The information obtained is not only informative, since it reflects the current trends in the distribution of one of the types of ice-frost deposits, which are adverse weather phenomena, but also allows you to plan the work of weather-dependent industries in more detail, ensuring their uninterrupted operation. Main results. It has been established that most of the deviations of the average number of ice cases for the study period relative to the period of 1981-2010. were insignificant, but in some areas during the cold season, especially in winter, they reached higher values. values. It has been established that in January and December there is a predominance of positive deviations of the average number of ice cases in Ukraine. Most of the centers of positive deviations are based on the territory of the western region from Volyn. Rivne and Zhytomyr regions to the Carpathians, as well as in the north of the Chernihiv and Sumy regions, as well as in a number of central regions from Vinnitsa to Poltava and Dnepropetrovsk regions. Also, noticeable foci of such deviations are observed in the north and east of the Kharkiv region, as well as in the north of the Luhansk region. They are noticeable in the south of the country. In February and March, foci of negative deviations were most often encountered. The most pronounced of them were observed in the western region in the territory from the Zhytomyr region to the Carpathian region, as well as in some central regions. In February, a focus of positive deposits was discovered in the north of the Chernihiv region. In April-October, the field of ice deposits for 1991-2020. compared to 1981-2010 prac

The main purpose of the research is to improve the efficiency of management decisions in the field of environmental protection through using the methods for assessing the public health risk at the current level of air pollution. Methodology. The article presents a hierarchical methodological approach for determination of the level of air pollution hazard at the state, regional and local levels. The state of atmospheric air is greatly affected by emergencies associated with accidents at chemically hazardous facilities, which result in burst releases of hazardous chemicals into the environment. When determining the environmental risk of deterioration in the state of atmospheric air, the chemical hazard indicator was taken into account. Results. On the territory of the East of Ukraine there is the largest number of potentially dangerous enterprises. A new methodology of determination of the hazard level of air pollution is presented at the existing trends of anthropogenic load and the possible occurrence of technogenic emergencies. Assessment of public health risk due to air pollution in the Mariupol city showed an extremely high level of danger. The determination of the risk as a macroecological indicator according to the new method shows a high level of hazard of air pollution in the industrial developed regions of Ukraine. The shortcomings of the methodical approach of the United States Environmental Protection Agency (EPA US), widely used in many countries of the world, are shown. An analysis of methodological approaches to assessing the public health risk has shown the promise of using the methodology for assessing potential risk in determining the level of environmental hazard of industrial enterprises. The assessment of the public health risk in the current quality state of air is given by two different methods for the regions of Ukraine with a high level of ecological and chemical hazard. The improvement of the methodology for assessing the risk to public health due to air pollution is proposed, which is presented as a scientific novelty. Currently when Ukraine has been affected by hostilities and the economic crisis, the issue of priority funding for environmental protection is very important. The implementation of the proposed methodological approach will make it possible to scientifically determine regions with an increased level of hazard to public health and minimize financial resources for improving the air quality, which has actual practical significance.

Formulation of the problem. Water erosion of soils is the most widespread and dangerous soil degradation process in Ukraine. The development of an effective system of soil protection measures requires the use of spatially distributed mathematical models of soil erosion losses. This, in turn, highlights the problem of spatially distributed source data, which adequately reflect the spatial differentiation of factors of the erosion process, among which the main one is the relief. The purpose of the article. Assessing the adequacy of available spatially distributed source data, including cartographic and freely distributed global digital elevation models (DEMs), for spatially distributed quantitative assessment of soil erosion losses at the local level of territorial coverage is the aim of the article. Assessing from this point of view the scale of the original cartographic data, different global DEMs and their spatial resolution, as well as the degree of spatial generalization of the original data. Materials and methods. The solution of the set tasks was performed by the method of simulation modeling with the use of physical-statistical GIS-realized mathematical model of soil erosion-accumulation, developed at Odessa I. I. Mechnikov National University. Source data arrays were tested with DEMs SRTM90 and SRTM30 with a spatial resolution of 3 and 1 angular seconds, respectively, and AW3D30 with a spatial resolution of 1 angular second, as well as with cartographic DEMs based on topographic maps of scale 1:10000 and 1:25000. For testing the initial data, three test plots with an area of 2.67, 0.59 and 0.21 km2 were selected. The plots are located in the Balta district of Odessa region on the southern spurs of the Podolska upland. Results. It is established that freely distributed global digital elevation models SRTM and AW3D30 in the conditions of flat terrain do not always allow to adequately display the structure of slope runoff and, accordingly, to correctly perform calculations of soil erosion losses. The maximum deviation of the average soil erosion losses calculated for the test plots using global DEMs from the soil losses calculated using the reference DEM for SRTM30 and AW3D30 was 27%, for SRTM90 – almost 70%. The distribution of soil losses over the area of test plots obtained using different global DEMs differs even more. When using DEM based on topographic maps, reducing the scale of the original maps from 1: 10000 to 1: 25000 leads to a decrease in the average value of soil erosion losses by about 20% due mainly to reducing the magnitude and area of distribution of maximum soil losses, and on slopes of complex shape also due to changes in the area of accumulation zones. The degree of spatial generalization of the initial data significantly affects the results of the assessment of soil erosion losses both in relation to the average values and their distribution over the area.

Problem statement. The increased human pressure on natural geo-complexes is causing the revival of undesirable processes that create an extensive risk for the inhabitants of these regions. Alpine-type orogenic zones, which belong to the northeastern slope of the Greater Caucasus, are distinguished from many geomorphological systems by excessive activity of endo- and exogenous processes. Therefore, at this time, the task of diagnosing and assessing the ecological and geomorphological risk that the population faces in the development of new territories of the region seems to be important. Analysis of recent research and publications. After analyzing a number of techniques used to assess the landslide and mudflow hazards, the conclusion was made that most of them had their flaws. Research method. There are a large number of methods for assessing the risk of environmental management and predicting hazardous exodynamic processes. However, in modern conditions, these techniques are not sufficiently reliable. This, in turn, determines the relevance and the need to develop new or modernised methods of strategies for the prevention, protection, and elimination of the consequences of catastrophes and natural disasters. The purpose of this work is to reveal the geomorphological features and dynamics of the development of the most dangerous and often repeating landslide and mudflow processes based on field geomorphological studies, as well as fund literature, indicate the reasons for their formation and propose measures to combat them. Research results. The article discusses the results of ecological and geomorphological surveys on the northeastern slope of the Greater Caucasus, dedicated to the assessment of landslide and mudflow risk for the period from 1990 to 2020. To assess them in order to obtain morphometric characteristics (including the down gradient of slopes, the length and shape of slopes, areas of mudflow centers), large-scale (M 1:100000) topographic maps were used, as well as interpretation materials for different-scale and multi-temporal ASP. Based on the interpretation of the ASP within the studied region, in order to clarify the general picture of the dissection of the modern relief of the studied region, a map of morphometric tension was compiled, which includes the degree of vertical dissection of the territory, the down gradient of slopes, etc., and also maps of the risk of landslides and mudflows were compiled according to the degree of danger of landslide and mudflow processes, and the area of their distribution was calculated. Landslide and mudflow risk analysis mainly used high-resolution aerospace imagery (ASI) from CNES / Airbus, Maxar Technologies (GeoEye-1), and medium resolution Sentinel-2A and 2B. Thus visual and semi-automatic interpretation (classification with training) was performed in the ArcGIS environment.

Formulation of the problem. Today, in changing climate conditions, it is very relevant to study the impact of regional climate change on the regime of hydrological indicators and ecological status of the Siversky Donets river basin within Kharkiv region. Analysis of recent research and publications. Hydrometeorological studies are complex and large-scale. In the late 20th - early 21st centuries, a number of articles studied annual runoff of the rivers of Ukraine under the influence of atmospheric processes. Present-day changes in temperature and humidity of the territory affect the hydrological conditions of the rivers. The aim of the work is to assess the relationship between climatic and hydrological indicators (environmental dynamics) of the Siversky Donets basin against the background of regional climate change. In these conditions, monitoring of climate, hydrological and environmental indicators, allows us to make further management decisions on water resources management. Research methods are presented by statistical and cartographic analysis. The source data are a number of climatological, hydrological and environmental observations within the state network of the Ukrainian Hydrometeorological Center of the SES of Ukraine. Problems of further research. Modern changes in climatic conditions in Ukraine are characterized by locality and rapidity. Considering the volume of water use from the river Siversky Donets, the question arises about the water supply of the region, optimization of its use and further rational management. Presentation of the main research material. The dates of the ice cover have changed in recent years, and often ice phenomena may not occur at all. We can see significant warming in winter on the example of January air temperatures. Summer temperatures are growing the fastest (by 0.37°C every 10 years), autumn temperatures are in the second place in terms of growth rate. which means that stable ice cover on most rivers of the Donets basin has been absent in recent decades, which clearly indicates a warming trend. Practical value. Based on the main provisions of the national environmental policy of Ukraine on the use of water resources the study of changes in hydrological regime of rivers is of practical importance for sustainable management. Calculation of the IWP has revealed that most rivers belong to the third and fourth categories - "moderately polluted" and "polluted", but there are also absolutely catastrophic cases. Research results. Heavy economic burden on the waterway will increase its over-regulation. In future, comprehensive assessment of climate change impact on the hydrological conditions of the rivers will determine the degree of change in the ecological state of the waterways, their rational use and protect.

The purpose of the article. The article is devoted to the study of one from forms of syndynamics in Late Pennsylvanian time, namely phytocoenogenesis. The study of the phytocoenogenesis of ancient plant communities, i.e., the formation of new types of palaeophytocoenoses, is based on the research of vegetation diversity that is reflected in the ecological-floristic classification of the Late Pennsylvanian phytocoenoses of the Donets Basin by the Brown-Blanquet method. Material and research methods. The phytocoenogenetic researches consisted of the analysis of the changes of the species and syntaxonomic composition of vegetation cover throughout the Late Pennsylvanian. The peculiarities and main factors of phytocoenogenesis have been identified on the palaeosyntaxa in rank of the orders of the following vegetation types: wetland forests and woodlands of coastal lowlands, wetland forests and woodlands of deltaic plains, seasonally dry woodlands of river valleys and lagoon coasts. The palaeophytocoenotic data are based on the plant fossil assemblages from lacustrine, lacustrine-swamp, lacustrine-deltaic, floodplain-lacustrine, floodplain and lacustrine-lagoon deposits in more than 17 localities and 11 boreholes located within the Bakhmutska and Kalmius-Toretska troughs. Research results. Based on the analysis of the phytocoenogenetic processes (progressive and regressive development of plant communities) and the manifestations of phytocoenogenesis (formation of new communities and loss of old communities) in the development of the Late Pennsylvanian vegetation, three models of the formation of new communities and one model of the loss of communities from vegetation cover have been proposed. Each of the models reveals the relationship between the phytocoenogenetic processes and environmental changes. The evolution-progression model reflects the progressive development of palaeophytocoenoses that is expressed by the appearance of evolutionary new coenopopulations in the conditions of the expansion of landscape types (expanding biotopes). The migration-progression model conforms to the progressive development of palaeophytocoenoses as a result of the migration of plants from decreasing landscape types to expanding ones (expanding biotopes). The substitution-regression model is consistent with the regressive development of palaeophytocoenoses along with structure simplification and dominant substitution of plant communities due to the contraction of certain landscape types (decreasing biotopes). The elision-regression model of the loss of communities reflects the regressive development of palaeophytocoenoses that is expressed by the decrease in the number of coenopopulations and the number of individuals in remaining coenopopulations in the conditions of the contraction of some landscape types (decreasing biotopes). The scientific novelty. For the first time, the Late Pennsylvanian vegetation dynamics (syndynamic) have been studied. The proposed thre
