Purpose. Scientific and practical justification for the introduction of plantings of ornamental perennial cereals and roses of a landscape group in the urban system of the Shevchenkovsky district, Kharkov. Methods For inventory of lawn stands, ArcGIS software was used. The basis for creating an inventory map of lawn stands was two basic maps - “Basemap Imagery” and “OpenStreetMap. The calculation of the total area of the research objects was carried out by using the Attribute Table. Assessment of the design coverage and constitutional structure of the species composition of lawn stands was carried out by A. A. Laptev and E. V. Avdeev. Observation of the ecological state of urban rose gardens was carried out by route examination, the presence of pathologies was determined visually. To determine the optimization measures, the SWOT analysis method was used. Results. An inventory map of urban lawn stands was developed. According to the results of a visual assessment, the T. G. Shevchenko city garden is the standard of landscaping in many territories and has a high level of quality of lawn stands. "23 August" Square sections of lawn populations near the Botanical garden station metro, square on the Klochkovskaya street includes areas of lawn stands with an excellent, good, satisfactory and unsatisfactory level of quality. The surface of Sargin Yar is well planned, the sites have an excellent, good and satisfactory level of quality. Based on the results of lawn stands comprehensive assessment, maps of the quality levels of urban lawn stands for the main recreational zones of the Shevchenkovsky district have been developed. The use of decorative cereals in particular, the impregnation of cylindrical, Chinese Miscanthus, feather grass feather, cane falaris, lightning blue is proposed. Using the SWOT analysis method, the strengths and weaknesses of the lawn stands of the Shevchenkovsky district, the possibilities and risks of their creation are determined. According to the results of an integrated ecological assessment of the varieties of landscape roses "Cordula" and "Tornado", the feasibility of their use in urban gardening is shown. Keeping these varieties in container culture can positively affect the artistic expressiveness of the urban sulfur, will provide a "high concentration of beauty" and solve the problems of wintering. Conclusions. Taking into account the principle of relevance in order to minimize the cost of further supporting the urban landscape, it is possible to develop cost-effective projects for landscaping areas with an unsatisfactory level of quality of lawn cover using decorative cereals. The proposed types of cereal plants are resistant to environmental factors, unpretentious, require minimal maintenance, have a high aesthetic appeal and decorativeness, low cost of creation.

Relevance. The development of measures to prevent possible negative environmental, economic and social problems in forest ecosystems should be based on objective information, which may be provided by the process of landscape-environmental planning. Purpose. Analysis of the conflicts of nature use from anthropogenic activity in forest ecosystems to develop measures optimization of environmental management in the process of landscape-ecological planning. Methods. The assessment of conflicts of nature use in forest ecosystems was carried at the test site of the tract "Zarudska Dacha" of Lyubovytsi forestry of the Malinsky district of Zhytomyr region according to the author's method of landscape-ecological planning. Results. Based on the results of the inventory and evaluation phase of landscape-ecological planning, we have obtained information about the landscape differentiation of the test area, internal and external sources of envi-ronmental conflicts, their boundaries, and intensity. The study of the structure of forestry has shown that the sources of conflict are predominantly forest areas and settlements landscapes. The assessment of intensity of the conflicts has shown that medium-intensity conflicts prevail in the territory. Based on the information of matrices of the conflict measures to optimize the use of nature in forest ecosystems have been developed. Conclusions. For optimization of nature use in forest ecosystems, it is recommended: restoration of plantations, control of rational use of forest resources, reduction of the volumes of use of the chemical means on the adjacent fields, organized garbage collection, controlled recreation, etc.

Purpose. Environmental assessment of the quality of surface water of small and medium rivers of the Poltava region, in particular: medium rivers – Psel, Vorskla, Merla and five small rivers –Govtva, Grun, Kolomak, Poluzorie, Tashan. Methods. Field, atomic absorption spectrophotometry, cluster analysis. Results. In accordance with the quality standard for surface water of cultural and household purposes, all indicators for medium-sized rivers are within the normal range. There was an excess of zinc in the waters of small rivers - Grun, Tashyas and Poluzorie. The low content of soluble oxygen does not meet the norm. When comparing values with the norm of quality of water for reservoirs of fishery management, excess BOD-5 for the Vorskla and Psel rivers is defined; the content of ammonia and nitrites significantly exceeded the normative value for the river Vorskla, Psel, Merla. The excess of surfactants for medium rivers is determined. The river Vorskla is mostly polluted with cupper; the Psel river – with zinc and iron, in water from the Gotvva, Tashan, Poluzorie and Grun rivers we have identified exceeding BOD-5. Regarding the water-soluble nitrogen compounds, only the nitrogen content corresponds to the normative value. The greatest pollution with ammonia is observed for the Govtva and Kolomak rivers. Excess of MAC on the content of nitrites was identified for the Kolomak river. As a result of the cluster analysis of the river, the degree and nature of pollution of surface water are grouped into three main groups: the first is the Kolomak river, the second one is the Merla, Psel, Grun, Vorskla rivers, the third one is the Tashan, Poluzorie and Govtva rivers. In the future, the results can serve as a tool for regulation, monitoring and solution of pollution problems. Conclusions. Small rivers of Poltava region are under considerable anthro-pogenic impact, their ecological status is estimated as ecological regression. Therefore, priority attention should be paid to improving the ecological status of small rivers in the Poltava region and implementation of the pro-posed nature conservation measures.
