The problem of assessing the natural-resource potential of landscapes and natural-aquatic complexes (NAC) of lakes, in particular, is updated. Lakes represent water, biotic, organo-mineral, and recreational resources. Tourist facilities, sanatoriums, recreational shelters, fish farms, sapropel mining enterprises, natural parks, and nature reserves operate on the base of the lakes. Given the above, there is a need to study the landscape-resource potential of lakes, primarily sapropel resources, which will become an information base for investors and integrated management of water resources. The purpose of the research is to substantiate the landscape and geographical features of Terebovichi lake and the resource potential of sapropel for the needs of balanced nature management. In the research process, methods of bathymetric profiling of lakes, general limnological methods, soil-geochemical profiling, landscape-limnological methods, GIS-cartographic modeling of lakes and lake-basin systems have been used. Research results. A digital bathymetric map of the lake has been created Terebovichi, with a depth interval of 0.25 m and a local deepening with the greatest depth of 2.4 m, has been found, and the reservoir's main morphometric and hydrological parameters have been calculated. A stratigraphic section of lake sediments has been made with the dissection of three types of sapropel (organo-clay, organo-iron, limonite), and a cartographic model of the landscape structure of the NAC lake has been constructed, and its landscape metric analysis has been carried out. Conclusions. It was established that the basin of Terebovichi lake is 79.34% filled with sapropel deposits. The area covered by sapropel is 50.0 ha, partially extending beyond the reservoir. The average thickness of sapropel is 5.46 m, and the maximum is 11.3 m; the total volume of sapropel is 2239 thousand m3. Balance geological reserves of sapropel – 498 thousand tons, off-balance reserves – 61 thousand tons. The lake is promising for the development and extraction of sapropel.

The article analyzes the territories and objects of the nature reserve fund (NRF) of the Chernihiv region as objects of recreational and touristic nature use. The NRF of the Chernihiv region includes 678 objects with a total area of 263.1 thousand hectares (7.89% of the territory of the region). The NRF of the region consists of eight categories, there are no such categories as biosphere reserve, nature reserve and botanical garden. The study of the dynamics of the number of objects and areas of the NRF of the region for the period from 1990 to 2023 revealed a tendency to increase multifunctional protected areas (national natural parks (NNP) and regional landscape parks (RLP)). Reserves and natural monuments predominate in the structure of NRF of Chernihiv region in terms of number, and in terms of area - reserves and regional landscape parks.
It was established that the most important for the recreation and tourism sphere are the multifunctional categories of NRF - NNP and RLP, in which tourism is actively developing. The main directions of tourism development in the Mezyn and Ichnya National Parks were analyzed - ecological trails, routes (car, bicycle, pedestrian) that provide an opportunity to get to know the nature of Polissia (Mezyn National Park) and the Forest Steppe (Ichnya National Park), and tourist infrastructure are indicated. It was determined that the most common type of tourism within the NNP is walking along ecological trails.
A special issue is the use of the recreational potential of nature reserves, which are the most widespread in the structure of the NRF of the region. It has been established that the predominant type of recreational and tourist activity within their borders is educational excursions along marked trails. Other categories of NRF of the Chernihiv region (natural monuments, arboretum, zoo, parks-monuments of horticultural art) have less recreational potential, but have educational value and can act as objects of recreational and touristic nature use. In order to increase the role and significance of the NRF of Chernihiv region in the structure of recreational and touristic nature use, it is advisable to create such categories of NRF as NNP and RLP.

The chemical dissolution of CdTe single crystals, ZnxCd1-xTe and CdxHg1-xTe solid solutions in HNO3 – KI – dimethylformamide solutions has been investigated under reproducible hydrodynamic conditions for the first time. It is shown that the etching compositions of this system are cheaper, create a less aggressive environment, are more stable over time and are more ecologically safe. The diagrams «solution composition versus dissolution rate» has been plotted and the concentration limits of polishing etchant have been determined. Chemical-dynamic polishing with the investigated solutions can be carried out with a volume content of HNO3 9-15 %, while the polishing speed the surface of CdTe single crystals, ZnxCd1-xTe and CdxHg1-xTe solid solutions is within 1.6-2.5 μm/min. The dependence of the ions concentration that passed into the solution after the interaction of solid solutions ZnxCd1-xTe with the investigated etchants, versus the content of the oxidant in the etchant has been determined, and it was shown that the content of ions in the solution corresponds to the molar ratio in the semiconductor and indicates uniform dissolution of the surface. Based on the results of kinetic study, the apparent activation energy of the polishing was calculated for a solution of the composition (in vol. %): 12 НNO3 + 88 KI (DMF), which does not exceed 15.1 kJ/mol for СdTe and 7.7 kJ/mol for solid solutions on its basis, which indicates the limitation of the process by diffusion stages. The effect of the lactic acid and the nature of the semiconductors on the kinetics of chemical-mechanical polishing of the studied single crystals were determined. When the polishing solution is diluted with organic acid to 40 vol. %, the speed of chemical and mechanical polishing decreases from 3.5 to 0.5 μm/min. The compositions of etching mixtures and modes of implementation of chemical-dynamic polishing, which is recommended to be carried out in a suitable installation at the temperature 293 K and the disk rotation speed 82 min‑1, and chemical-mechanical polishing of the mention above semiconductor single crystals with the addition of lactic acid and polishing rates of 3.5-0.5 μm/min.
首次在重现流体动力学条件下研究了CdTe单晶、ZnxCd1-xTe和CdxHg1-xTe固溶体在HNO3 - KI -二甲基甲酰胺溶液中的化学溶解。结果表明，该系统的蚀刻成分更便宜，创造了一个更少侵略性的环境，随着时间的推移更稳定，更生态安全。绘制了“溶液组成与溶解速率”图，并确定了抛光腐蚀剂的浓度极限。在HNO3含量为9 ~ 15%的情况下，该溶液可进行化学动力学抛光，而对CdTe单晶、ZnxCd1-xTe和CdxHg1-xTe固溶体表面的抛光速度在1.6 ~ 2.5 μm/min之间。测定了ZnxCd1-xTe固溶体与所研究的蚀刻剂相互作用后进入溶液的离子浓度与蚀刻剂中氧化剂含量的关系，表明溶液中离子的含量与半导体中的摩尔比相对应，表明表面溶解均匀。根据动力学研究结果，计算了12 НNO3 + 88 KI (DMF)溶液的表观活化能，在此基础上，СdTe溶液不超过15.1 kJ/mol，固溶体溶液不超过7.7 kJ/mol，表明扩散阶段对抛光过程的限制。测定了乳酸和半导体性质对所研究单晶化学机械抛光动力学的影响。当有机酸将抛光液稀释至40 vol. %时，化学抛光和机械抛光的速度从3.5 μm/min降低到0.5 μm/min。对上述半导体单晶进行化学机械抛光，添加乳酸，抛光速率为3.5 ~ 0.5 μm/min，建议在合适的安装条件下，温度为293 K，磁盘转速为82 min - 1，蚀刻混合物的组成和化学动态抛光的实现方式。

The paper proves the possibility of conducting water quality assessment using such an indicator as the species assemblage of Unionidae habitats for the purpose of conducting local bioindication. According to the species assemblage of Unionidae habitats, it was established that of the five analyzed sites of material collection of the main stream of the Teteriv River, in one case the water quality can be assessed as "Dirty", which corresponds to the IV water quality class, and in three cases as "Contaminated", which corresponds to the III class, and in another one - as "Good" - II class of quality. The rivers Guiva (Ivankiv), Kroshenka and Putyatinka within Zhytomyr belong to the IV class of water quality. Five more points are assigned to the II quality class (Guyva River in the area of Pryazhevo and Zarichany villages; Kam'yanka River (Zhytomyr); Kodenka River (Vertokiyivka village) and Hnylop'yat River (Berdychiv).More detailed information about the ecological state of aquatic ecosystems is provided by the use of algal communities of plankton as biological descriptors, but this approach is time-consuming. In general, the bioindication of water quality in the rivers of the Teteriv basin according to phytoplankton showed the predominance of indicators of saprobity, which correspond to the III class of water quality ("Contaminated"). Class II ("Good") indicators make up a significant share. A moderate level of organic water pollution is indicated by the predominance of eurysaprobes in the rivers. In terms of phytoplankton biomass, the Teteriv and Kroshenka rivers belong to the III class of water quality, other watercourses belong to the II class. According to the saprobity index, the water quality of the Teteriv, Putyatinka, and Kroshenka rivers is rated as satisfactory, and that of other watercourses as good. According to primary production and the ratio of production and destruction processes, watercourses were ranked into three groups - those belonging to II, III and IV water quality classes. The average values of the integral index ∑А/∑R for all watercourses, except for the Putyatinka River, are higher than 1. This indicates a positive balance of organic matter, characteristic of aquatic ecosystems with a high intensity of photosynthesis. The predominance of the heterotrophic phase in Putyatynka is most likely a response of the watercourse ecosystem to anthropogenic pressure.A comprehensive assessment of the water quality of watercourses in urbanized areas using as biological descriptors the ecological state of hydroecosystems of algae, plankton and mollusk settlements is the foundation for further ecological monitoring of waters, forecasting changes in the autotrophic and heterotrophic links of aquatic ecosystems under the influence of environmental factors.

Today, there is significant contamination of soils with various chemical substances due to the action of the anthropogenic factor. Fluorine compounds are one of the dangerous pollutants contaminating the soil. The main source of their entry into the soil is the application of phosphate fertilizers, which contain fluorides in the form of impurities. In Ukraine, the problem of soil contamination with fluorides is particularly relevant due to the significant volumes of agro-industrial production.
Fluorine compounds pose a particular danger due to the ability of their mobile (soluble) forms to spread (migrate) over considerable distances in the soil solution. This leads to the possibility of contamination of territories that were not directly fertilized.
The article describes the importance of fluorine compounds for living organisms, as well as the consequences of their lack and excess in plant and animal organisms.
Forms of the existence of Fluorine compounds in soils have been established: mobile form (soluble fluorides: NaF, KF) and immobile form (insoluble fluorides: CaF2, AlF3, FeF3), which are in constant dynamic equilibrium. The main factors affecting the relationship between the specified forms in the soil are described.
In the course of the research, the content of mobile compounds of Fluorine in the soils of the coastal zone of the Huska River was measured. During the analysis of soil samples in 2021, a significant level of contamination was revealed. Exceeding the MPC was found in 9 samples out of 18 (MPC of mobile fluorides in soils – 2.8 mg/kg). On average, the samples exceeding the MPC had a fluoride content of 4.95 mg/kg. In 2022, none of the 20 samples exceeded the MPC of mobile fluorides.
During the analysis of the obtained results, the phenomenon of migration of mobile compounds of Fluorine was investigated. To detect the phenomenon of migration of mobile compounds of Fluoride in the soils of the coastal zone of the Huska River, a sampling scheme was drawn up in order to monitor the content of fluorides along the potential direction of their migration. That is why the soil samples were taken in pairs: "field" - "shore", where "field" is the territory where phosphate fertilizers were applied, and "shore" is the coastal area that is close to the point of sampling from the field. Therefore, according to the results of research in 2021, a significant level of migration of mobile compounds of Fluorine was revealed. In particular, in 3 out of 9 pairs of samples, the MPC was exceeded both on the territory of the "field" and on the "shore" site. This indicates a certain contribution of the phenomenon of migration to the pollution of the environment by mobile compounds of Fluorine. Thus, according to the results of the study, the presence of the phenomenon of migration of mobile fluorides in these territories was revealed. This is evidenced by the exceedance of the MPC of fluorides in areas where fertilizers wer

We have identified 10 species of naked filose amoebae in different types of water bodies in Ukraine. Original morphological descriptions have been compiled for all species. The most common species are Arachnula impatiens, Penardia mutabilis, Nuclearia delicatula, Biomyxa vagans, Vampyrellidium perforans, Nuclearia flavocapsulata, the least common are Vampyrella lateritia, Lateromyxa gallica, Leptophrys elegans, Leptophrys vorax. Established ecological groups of these protists in relation to the abiotic factors of the aquatic environment: euryoxidic (N. delicatula, N. flavocapsulata, A. impatiens, P. mutabilis, L. elegans, L. vorax, V. lateritia), stenooxidic (V. perforans, B. vagans, L. gallica), stenobionts (A. impatiens, V. perforans, B. vagans, L. gallica) and those that withstand a wide range of permanganate oxidation values (N. delicatula, N. flavocapsulata, P. mutabilis, L. elegans, L. vorax, V. lateritia). The largest number of species of these protists is observed in rivers (8 species) and floodplains (7 species), the smallest – in swamps (3 species); 5 species of filose amoeba were found in the lakes. We encountered P. mutabilis only in rivers, B. vagans in swamps, and V. perforans in floodplains. L. elegans, L. vorax species, which can be considered eurytopic, occurred in all types of reservoirs. The largest share of common species of naked amoebas is observed between rivers and floodplains (0.80), rivers and lakes (0.77), floodplains and lakes (0.67) and lakes and swamps (0.50), the smallest – between floodplains reservoirs and swamps (0.40) and rivers and swamps (0.36). According to the species composition of naked filose amoebae, two species complexes are distinguished: swamp and floodplain, which includes species that mainly occur in rivers and in reservoirs located in river valleys. The species complexes of rivers, floodplains and swamps are influenced to a greater extent by water temperature and the concentration of organic substances dissolved in water, and to a lesser extent by the concentration of oxygen dissolved in water. The species composition of naked filose amoebas of rivers and floodplains is associated with a higher temperature and a higher content of organic substances dissolved in water compared to the species composition of swamp amoebas.

Today, the deep and wide implementation of geoinformation technologies in the many fields of human activity is due to the powerful development of three scientific and technical components: statistical, software, technical and space technologies. In this article, based on GIS technologies, an analysis of the state of land use and its changes in the territory of Zhytomyr oblast was carried out, also how russian aggression against Ukraine affected these processes. The structure and the dynamics of the main classes of the land cover of the oblast for past 7 years were analyzed, the main causes and consequences of such trends were determined, and the analysis of changes in the land cover was carried out. According to the results of this study, in 2022, 52% of the territory of the Zhytomyr oblast was under forested areas, which consist of two categories: forests and other forested areas. The first category remained unchanged during the studied period since the government system of protection and reproduction of forest resources functions effectively. While the second category significantly decreased due to the fact that firewood is the most available of the fuel resources for heating building, so the population began to harvest wood in the form of felling and clearing old gardens, forested bushes and rivers (irrigation canals), forest strip. Agriculture of the Zhytomyr oblast is developing due to extensification. According to Google Dynamic World data, in 2022, 34% of the territory of the Zhytomyr oblast is systematically used for growing agricultural crops. Over the past seven years, there has been a significant increase cultivated land by 27%. In the structure of the land cover of the Zhytomyr oblast, the grass cover is 4.9%, but it is gradually decreasing. A decrease was observed for all types of territorial communities until 2021 (10% annually on average), while in 2022 the decline slowed down significantly in rural and village territorial communities and stopped in urban ones. This dynamic is connected with two factors: 1) part of the gardens of rural households were sown with grass due to the fact that men were mobilized to the Armed Forces of Ukraine as a result of russian aggression, and growing grass requires the least human costs; 2) russian aggression caused a shortage of certain food products and their significant increase in price, while keeping cattle provides food for the rural household, so in 2022 most of the offspring from cattle were not sold and left for further maintenance, in turn, the increase in cattle requires more feed, an important component of which is grass.

There is considered the activity of geodesy and cartography department of geographical faculty of Taras Shevchenko National University of Kyiv from time of its institution to present time. Chronologically 3 main topics exposed: educational and scientific functioning, structural and organization instants and personnel policy of department. To mark the periods in development of the department we took the structure of competences which were to have formed in students during theirs training. There we considered the correspondence level of educational programs to business demands too. It was proposed the structure of the educational program which is focused on perspective economy inquiries (2020-2030’s) and the wording of which is the result of a separate unfinished research. Besides the subdivisions role in educational and scientific achievements we also disclosed the personnel policy and organizational work of the heads of the department. There are separately stated the history of scientific subdivision and pointed out on the causes of its reorganization. In the other hand we discussed the influence of external factors onto educational process, in particular computing machinery appearance, gaining of national independence and change of state economy model, conversion of cartographic production to digital technology, implementation of the Bologna education system. In the final part of the article we recounted the demands for education department functioning in actual conditions of high cost of study, changing of profile specialties and academic competition for the best students with other universities which have the departments with similar specialization.

The second half of XX century – the beginning of XXI century are characterized by the active development of a global ecological crisis, which is described by a critical state of the environment and excessive anthropogenization of a geographical sphere. The changes which lead to the formation of absolutely new techno-genic landscapes occur at very fast rates in current geo-spheres. The purpose of the work is to substantiate the recognition of a new geo-sphere – a landscape techno- sphere – based on the previous experience and our field research. The main tasks of the research are to analyze specific features and properties of a landscape techno-sphere; to identify its upper and lower borders; to study a structural organization of all options of a landscape sphere with available techno-substances; to characterize briefly the main stages of the development of a techno- sphere. The research of a landscape techno-sphere is a complicated process and it is based on the use of classical and innovative methodological principles of contemporary geography. A parallel application of three scientific paradigms is the foundation: system, model and ecological. They do not contradict each other; they rather compliment the studying of the interaction between nature and engineering. A system approach allows considering a techno-sphere as a complicated system of a lower taxonomic range of a landscape sphere and a geographical sphere. The following generally accepted scientific methods are used in the paper: analysis, synthesis, comparison, generalization, systematization, induction and deductions. The article substantiates the existence of a new geosphere – the landscape techno-sphere, which is formed by the planetary set of landscape-technical systems. it is noted that it does not have a continuous distribution, but is constantly increasing in size and gradually goes beyond the landscape. The specific features and properties of the landscape techno-sphere are analyzed in detail. Taking into account the criterion of the presence of a zone of direct contract of three blocks of landscape-technical systems (managerial, technical and natural), the upper and lower limits of the landscape techno-sphere are identified. The structure of all variants of the landscape sphere in the presence of technological substances is considered. The main periods of development of the landscape techno-sphere are briefly described. It is concluded that man will never be able to control landscape-technical systems on a planetary scale. However, applying the methods and principles of engineering landscape research, it is possible to achieve optimal interaction of the three blocks of landscape-technical systems and to extend their functional suitability.

The article is devoted to the actual problem of determining the invasive potential of the invader species, the Armenian rock lizard Darevskia armeniaca. A population of introduced parthenogenetic rock lizards Darevskia armeniaca has existed in the canyon of the Teteriv River (Zhytomyr region, Ukraine) for about 60 years. Their presence in the herpetofauna of Ukraine is the result of a scientific experiment aimed at studying the processes of acclimatization and the existence of a local population of clones in a limited area, the possibilities of hybridogenesis of parthenogenetic and bisexual species and other issues of population genetics. The invasive potential of rock lizards in this area was studied by the method of bioclimatic modeling of the ecological niche. The material was based on data from the Global Biodiversity Information System (GBIF.org (03 November 2021) GBIFOccurrenceDownload. To model the ecological niche, 19 bioclimatic variables, average monthly data on solar radiation intensity for the modern period (1970-2000), data on altitude from the WorldClim 2.1 database were used. Most of the significant parameters of the ecological niche for the introduced population are in the lower pessimum zone. The model built based on the entire collection of points of registration of the species shows that the territory where the species was introduced in Ukraine is one of the least suitable. Nevertheless, the population of introduced parthenogenetic rock lizards is now stable, thriving, numerous and slightly expanding its range by inhabiting new territories. Obviously, favorable conditions for the existence of D. armeniaca here are determined not by macroclimatic factors, but by microclimatic ones. The analysis of the model built on the basis of points of registration of the species in the introduced population shows that under existing climatic conditions, wide expansion of the species in this region of Ukraine is not possible, although a small expansion of its range is quite likely. There is also no reason to predict the transition of rock lizards to the number of invasive species.
