【 摘 要 】

Expansion of urbanized areas and activity of technogenic systems led to the emergence and operation of a set of environmental factors that determine the flow of life processes in new conditions. Under the influence of anthropogenic factors including man-made (industry, energy, transport) and economic activities (construction, utilities, recreational load) in the environment, a number of environmental problems arise and develop, aggravated by unfavourable weather conditions for dispersion of harmful impurities in the air, which is especially important for Krasnoyarsk city. Biological monitoring is necessary to assess the environmental consequences of human impact, to ensure the necessary level of environmental quality and the environmental safety of the urban environment. Recently, researchers have been analysing the degree of impact of environmental factors through developmental sustainability (fluctuating asymmetry). This paper shows an assessment of the stability of the development of tree plantations growing in the zone of influence of an aluminium plant and heat and power engineering enterprises. For the study the most common tree species were selected, which are widely used for landscaping cities: apple berry, wild cherry, balsam poplar, elm squat. The representativeness of the data obtained is confirmed by appropriate statistical processing. Morphometric indicators of the lamina (j3, j4, j5) of apple and berry apple trees sensitive to negative environmental factors, intensified under the influence of emissions from an aluminum plant, are revealed. An identical response of indicator species belonging to the same family was found.
