“…One of the means to restore eco-balance in the urban environment is the development / reconstruction of organized science-based green structures [7,8]. At the present stage of the scientific and practical search, the composition and city-planning, natural and climatic, financial nuances of planting have been thoroughly studied, but the ecological justification for the development of the green systems of a large city is not enough, which is required in connection with the growth of urban transport, the increase in housing density, the functioning of industrial enterprises.…”

The subject of the research: the ecological justification of planting a large city in the context of the formation of conditions for its sustainable development. Objectives: to develop a methodology for determining priorities for planting to minimize the risks of damage to the environment and public health. Materials and methods: statistical and cartographic data, full-scale investigations of insolation regime and humidity characteristics, compositional city planning and technogenic nuances that cause the ecology of a million-industrial city (using an example of Volgograd). Research methods-statistical and cartographo-correlation analysis, geoinformation modeling, valuation technique for spread of pollution on the ground. Results: local and summary maps of atmospheric air pollution in Volgograd were built by industrial enterprises with the definition of the boundaries of pollution and the population under the influence; the zones of noise pollution and dispersion of carbon monoxide from motor vehicles (up to 180 m) were estimated, and as well as a higher content of heavy metals in soils near highways with a higher percentage of freight transport in the stream was detected; the oppressed state of the system of urban planting and below the normative provision of the population with plantations of common use were revealed. It has been established that sanitary protection zones do not have the proper density of green mass. Direct correlation between pollution levels and morbidity indicators, as well as inverse relationships between morbidity rates and the degree of planting are revealed. The author's algorithm for calculating the requirement ratio for planting (KPO) is developed, which allows to assess the ecological picture of the analyzed territory, its potential for living / recreation of the citizens without the risk of causing direct harm or long-term health consequences, and the requirement for operational implementation environmental protection measures in the form of planting. Conclusions: 1) in Volgograd, foci of ecological disadvantage have clearly formed, under unfavorable weather conditions, at least 120,000 people will be exposed; 2) planting is in a depressed state, and the population's supply of public green spaces is below the standard level by 2.5 times as a whole in the city and 3-4 times in some administrative districts; 3) the revealed correlation links testify to the negative impact of man-made impact factors and the compensation potential of the public access system of urban planting; 4) the developed author's algorithm for calculating the requirement ratio for planting (KPO) allowed to carry out a comprehensive ecological zoning in Volgograd, to determine the priorities for environmental protection measures and from the ecological point of view to structure the concept of urban planting.

The study of the state of green spaces in urbanized areas is important due to their sanitary, hygienic and aesthetic role in the harsh climatic conditions of the Arctic. The objects of research were the green spaces of the urban-type settlement Nikel (the Murmansk region). The assessment of the distribution of tree and shrub species by categories of life state was carried out; revealed damage to leaves by atmospheric emissions, insects and fungi. A high degree of damage from pollution was noted in birch, mountain ash and bird cherry; aspen up to 85 % damaged by aphids; mechanical damage to the trunks was noted in about 26 % of the surveyed trees; 5 % of trees have frost cracks in the trunk. In the course of a comparative assessment of the chemical composition of birch leaves growing in the urbanized territory of Nikel and in forest ecosystems along the gradient of atmospheric pollution in the impact zone of the Pechenganikel plant, it was found that the concentrations of pollutants in birch leaves in technologically disturbed areas exceed background values. Birch leaves in the southern direction from the plant accumulate higher concentrations of Ni, Cu, Pb, Co, Fe than in the western and northern directions. In 2019, the concentrations of heavy metals in birch leaves increased compared to the previous study period (2004). In the urban area, the content of pollutants exceeds not only the values of the regional background, but also the levels identified in forest ecosystems along the gradient of atmospheric pollution. Concentration coefficients Cc show abnormally high values for Ni, Cu, Pb, Co, Fe; the maximum Cc values are noted for Ni and Co.
