The purpose of the study is to analyze the sanitary condition of tree and shrub vegetation on the territory of school No. 19 in the city of Yoshkar-Ola. This work is relevant, since the school is a place for long-term stay of children of school and preschool age and the natural environment is an integral part of their educational activities. To determine the assessment of the state of the stand, the coefficients of the state of plants are calculated: the states of individual trees are determined by the external signs of a 5-point scale. Next, the coefficients of the state of the tree species are calculated according to the corresponding formula. The coefficients of the state of the stand as a whole are also found as the arithmetic mean of the coefficients of the state of individual tree spe-cies. As a result, an assessment of the state of the stand according to this gradation was deter-mined. Woody plants growing on the territory of secondary school No. 19 in Yoshkar-Ola were examined. A total of 35 species of coniferous and deciduous plants have been identified. Most species are characterized by a weakened state. Plants of hawthorn-blood-red, poplar × 'Soviet Py-ramidal', prickly plum and mountain ash are the most weakened. The condition of the plantings as a whole is assessed as weakened. It is recommended to carry out agrotechnical measures for plants and cleaning of dead specimens.

The results of the landscape-ecological assessment of the park territory of cultural house 50-years of October in Voronezh are presented. This work allows you to determine the state of the object for its further use. This facility is located in the South-West district of the city and is used for recreation of the local population. The indicators of landscape-ecological assessment were determined: type of landscape, type of spatial structure, sanitary-hygienic assessment, aesthetic assessment, stage of digression. The results of the research showed that the site is in a relatively good sanitary condition, the indicator of aesthetic assessment is at a fairly high level. We also studied the plant species, which grow on the object and their condition. The assortment available in the park is represented by the list of woody plants: Robinia pseudoacacia, Betula pendula, Ulmus pumila, Acer platanoides, Tilia cordata, Populus alba, Populus pyramidalis, Sorbus aucuparia.All woody plants in the park is in good and satisfactory condition. Based on the results of the assessment of the territory, it is possible to outline design measures that will improve the sanitary, hygienic and aesthetic conditions at the facility. There is a need to design small forms of architecture (benches, urns), organize additional planting of trees, pick up flowering shrubs and create flower beds to enhance the attractiveness of the object.

The research object is the territory of the secondary school #19 of the city of Yoshkar-Ola. The topicality of the research is determined by the necessity to reconstruct the existing landscape areas on this territory. For the project “The reconstruction of landscaped areas and improvements on the territory of the secondary school #19”, the authors have reviewed the landscaped areas. The analysis uses complete enumeration based on mensurational description. During the analysis, the authors defined species, taxonomic characteristics, sanitary and hygienic and esthetic values of each taxon. 290 woody plants were examined. Based on the acquired data, the authors analyzed the current landscaped areas on the territory and formulated the following conclusions: the density of plantations is much lower than the recommended values; the authors noticed only the traces of a green fence. However, the average values of the sanitary condition are 2 and 1, which means that the landscaped areas are in a good condition, and the species composition is in line with recommendations. Due to the fact that the school territory radius is 2 km, the condition of landscaped areas requires special attention. The scientific novelty of the research is determined by the fact that the landscaped areas on territory in question need to be reconstructed.

<p>The purpose of our work is to assess the health state of woody plants growing in different habitats of the city of Aktobe. We have studied the health state of arboreal and shrubby plants growing in various urban habitats; the survey was conducted during 2016-2017 by route-visual method. We performed the analysis of species diversity, abundance and density in urban area. The assessment of health state of the trees was made according to V.A. Alekseev. From your data and literature review we established that such species as Ulmus pinnato-ramosa, Acer negundo, Populus tremula, Populus nigra, and Syringa vulgaris have strong winter resistnce in the territory of Aktobe; we registered that only their apex buds and emds of the shoots were frozen in severe winters. The medium-resistant speices include Ulmus laevis and Acer platonoides. They are less plastic and suffer from late spring and early autumn frosts. The Amorpha fruticosa, Vitis vinifera, and Parthenocissus guinguefolia could be considered as the non-resistant species, since they usually freeze up to the snow cover line. The analysis of the vital state made it possible to assess the resistance to urban conditions of the majority of trees and shrubs registered in urban habitats of Aktobe. According to the preliminary data, the origin of the plant and its winter resistance are of main importance when introducing new species to urban area.</p>

The paper presents the results of a comprehensive analysis of the species composition of Cheboksary. The analysis of the dendroflora of the urban environment was carried out according to 3 indicators: the territory of woody plants, the occurrence of woody plant species in landscaping, the structure of the landscaping system. The arboreal vegetation of Cheboksary is represented by 73 species belonging to 43 genera and 20 families. The predominant part of the dendroflora is represented by the covered-seeded plants (86,3%), the gymnosperms - 13,7%. In the dendroflora of green areas of the city, the most widely represented families are Rosaceae, Pinaceae, Salicaceae (48%). The analysis of the species composition of woody plants showed that in the functional and economic zones of Cheboksary plantings of general use are represented by 65 species, plantings of limited use - 52 species, plantings along the streets and main roads - 50 species. The analysis of the species composition of woody plants depending on the share of their participation in landscaping revealed that the greatest number of woody plants is used with low (51 species) and medium (50 species) share. The analysis of the degree of participation of woody plants in landscaping in the four identified functional and economic zones of Cheboksary found that the greatest number of taxa prevail with an average participation in the central zone (37 species), the coastal and suburban zones (36 species). The largest number of species of woody plants grow in the green areas of the central functional and economic zone, where the landscaping involved 66 species, the smallest number grow in the green areas of the industrial area (36 species).

Studies conducted in different cities have shown that trees growing in urbanized areas reduce noise levels and cleanse the air of solid particles, ozone, sulfur dioxide, carbon monoxide, nitric oxide and other pollutants contained in car fumes, transport dust and generated by industry. The reaction to the influence of negative factors in woody plants is in disturbances in metabolism and biochemical composition, their general development also changes, and their population decreases. The indicators of disorders occurring at the cellular and tissue levels are more sensitive to the influence of negative anthropogenic factors in comparison with external manifestations. The research was carried out on woody plants: small-leaved linden (L. Tíliacordáta), horse chestnut (L. Aésculus); the soil. The research was carried out in 9 districts of Volgograd. The assessment of the state of woody plants was carried out by the visual method based on external signs. GOST methods were used to determine the concentrations of chemical elements in the foliage and soil of woody plants. Using physical and chemical methods, the concentrations of chemical elements in the soil and biomass of woody plants taken from the selected areas of the city of Volgograd were obtained, and the correlation between these indicators and the life state of woody plants was determined. The dependence of the indicators of the concentration of nutrients in the soil and the state and viability of woody plants was well traced. In general, the state of most of the woody plants of the city was healthy or moderately weakened. Such a high level of the life state is explained by the relatively young age structure of the studied plants, because at a young age woody plants are more resistant to negative factors of the urban environment. The revealed features of the life of woody plants in the city can be taken into account in the practice of city green building.

This research was conducted to study pollen quality in woody plants in the city parks of Dnipro, which are located at various distances from the sources of anthropogenic pollution. It has been revealed that sterile pollen in its greatest abundance was present in plant species in the Park of Memory and Reconciliation and Molodyozhny park, as both are situated within the range of emission transfer from the Western Industrial Complex, while the least abundant sterile pollen was detected in the park named after Yu. Gagarin and that named after V. Dubinin. According to sterility indices, the pollen inBetula pendulaRoth. and that inAcer platanoidesL. were most sensitive to environmental pollution. In the city parks, the amounts of shrunk and abnormally shaped pollen grains increases; giant forms with grain diameters exceeding standard, as well as dwarf forms are not rare in occurrence. The highest percentage of pollen grains of atypical shape and size was observed in the same parks where the pollen sterility index had its highest values.
