Purpose. To assess the main trends in the formation of nature reserves and the degree of protection of the territory of Sumy region to determine the directions of development of the regional ecological net-work. Methods. Methods of historical analysis, statistical processing, spatial modeling, evaluation and generalization of the obtained data are used. Results. During the study period since 1991, the area of NPF has increased 5.44 times, and the num-ber of NPF objects - almost 2 times and in 2019 is 275 units. Comparison of administrative districts of Sumy region by the number of NPF objects allows to determine the districts - "leaders": Romensky (37), Sumy and Lebedyn (25 pieces each), Krolevets (24) and districts - outsiders - Buryn (5), Shostka (7) and Velykopysarivsky 8). By the area of the nature reserve fund "leaders" - Putivl district (39298.55 hectares) and Konotop district (32440.7 hectares). The discrepancy between a large number of objects and the area of the NPF prompted the determination of the percentage of reserves and modeling of the relationship between these three indicators. Based on car-tographic visualization and statistical modeling, recommendations have been developed, the main of which are: intensification of the creation of NPF objects of local significance, first of all, in the areas that are most "lagging behind" in the process of bequest; renewal of previously rejected NFP Projects and facil-itate their approval; initiating activities to promote tourist routes on unique natural, historical, ethnograph-ic sites of the NPF for economic support of communities. Conclusions. It is established that the degree of protection of the territory of Sumy region is lower than recommended and averages 7.43%. Spatially, there is a band of high concentration of NPF objects with relatively large areas, which even exceeds the recommended (Konotop, Krolevets and Putivl, or ac-cording to the new zoning - Krolevets district) in the central part of the region, which is surrounded on both sides by areas with low percentage (up to 5%) of protected areas and only the extreme northern and southern parts of the region (Seredino-Budsky, Trostyanetsky, Velykopysarivsky and Okhtyrsky districts) are approaching the norm in terms of the percentage of protected areas. The patterns identified by model-ing allow us to recommend increasing the share of NPF in the total area of the region in two directions - increasing the area of the existing facilities or creating a large number of new ones with small areas.

The purpose of the research is to establish and analyze the modern territorial structure of the nature management of the city of Kharkiv for further use in the process of its landscape planning. Methods. Visual decoding of satellite images, vectorization of raster images, analysis of topological correctness and mapometric calculation of areas. Results. On the basis of the analysis of satellite images of the city's landscape coverage and its subsequent classification according to the types of nature use, a cartographic work "Territorial structure of the nature management of the city of Kharkiv" was made. A quantitative assessment of the differentiation of different types of nature management has shown that the largest share is occupied by the residential type, represented by residential and public buildings - 39% of the city. The second type of nature use in Kharkiv is the protective and recreational type, which occupies 27% of the entire territory. Industrial type of nature management occupies 15% of the territory of the city of Kharkiv and is represented by industrial enterprises and mining quarries, which accounted for 98% and 2% respectively. The following territorial distribution is the agrarian type of nature use - 9% of the city's area. The largest share of agrarian type occupies the agricultural type of nature use - 67% of the total area of the type. All transport types of nature use together occupy 8% of the city, half of which are streets of local importance (51%). Conclusions. The main tendencies of spatial distribution of types of nature use are revealed, namely: industrial and residential types of nature management, form spatial "agglomerates", much of which tends to the neighborhood with the areas of aquatic nature use; Territories with an agrarian type of nature management are located on the city suburbs and represent "rudimentary" remnants of the "pre-urbanization" nature of nature use, the protective and recreational type has a unconnected territories and does not create the ecological environmental - stabilizing framework of the city. On the basis of the obtained data, the prospects and possibilities of using this approach to inventory cartographic works for the needs of landscape planning of territorial development of cities are presented.

The results of the comparison of archival topographic maps with materials tacheometry are presented. Found that the existing maps are outdated and do not provide objective information about the relief area. The possibilities of the program with respect to WEPP modeling of water erosion are shown.

Spatial databases management system significantly enhances the efficiency and productivity of GIS, work-ing as a database interface and tool for analyzing spatial information. Therefore, they are so important for soil mapping. By the local example (Kharkiv region) developed a technique of creating a spatial database to needs of soil-erosion survey of area. An approach to automate the process of field description of soil profiles are proposition.

The article highlights the problems of formation of conceptual and terminological apparatus in the field of alternative energy. Attempts to improve and systematize the basic terms and concepts in the industry were made. Inconsistencies and ambiguities in the interpretation of such concepts as «alternative energy resources», «non-conventional energy resources», «renewable energy resources», «energy sources», «energy resources», and «energy potential» were eliminated. Classification of energy resources based on the criteria of depletion, renewability, tradition of usage, and their origin was proposed. The structure of the object of mapping, according to the needs of alternative energy, is considered. The thematic content of cartographic products was determined. Mapping indicators of alternative energy resources; the current state of alternative energy development; environmental, social and economic factors that contribute to the development of the industry or limiting its development were identified.
