Annotation. This paper examines the existing in the Russian Federation approaches to assessing the quality of the urban environment, the concept of the quality index of the urban environment; the analysis of indicators for calculating the quality index of the urban environment and the factors that form the ecological well-being of the urban environment for the local population has been carried out. The territory of the northern industrial hub of Volgograd was chosen as the object of research, in particular, the zone of influence of the ferrous metallurgy enterprise AO “VMK ‘Krasny Oktyabr’”, which has a historically specific location relative to the functional zones of the city. The analysis of the results of monitoring the content of mobile forms of heavy metals in the soil cover, carried out by the method of atomic absorption spectrometry, and the assessment of the general life state of tree green plantations in the territory of the sanitary protection zone of the enterprise based on the enumeration of trees is presented. The identified zone of influence of the enterprise, taking into account the presence of additional sources of pollution of the soil cover and MPC of metals, instead of their background concentrations, extends for 3.5–3.7 km from the border of the enterprise in the form of elongated areas of increased concentrations. Cartographic visualization reveals the presence of two clearly pronounced foci of pollution located to the west of the existing SOC of the enterprise. When assessing the general condition of trees, it is also possible to recognize the worst territory of the test plots located to the west of the operating TWCs in accordance with the directions of the prevailing winds. The data obtained confirm the feasibility of organizing regular monitoring of the soil cover and the state of green forests in the city as one of the directions for assessing the quality of the environment and taking these indicators into account when calculating the quality index of the urban environment
Key words: Volgograd, environmental monitoring, assessment of the quality of the urban environment, soil cover, triangulation network, green forest plantations, assessment of the vital state.
