The morphological parameters of the maternal trees growth, seed progeny and seedlings, and the value of the fluctuating asymmetry (FA) of the leaves of adult plants under urban influence were estimated. Urban oak groves have a low growth rate of shoots. Rural and suburban oak groves are characterized by an increase in the shoot. The coefficients of variation (Cv) in the length and width of leaf blades are generally low; only for 1 territory near urban radius and experiencing the influence of industrial enterprises, the Cv of the length of the leaf blade is 29.3% and the width of the leaf blade - 30.4%. FA for all oak forests, with the exception of Chizhovskoe tract (0.056), not exceed 0.04, thus, they are resistant to the anthropogenic factor. The average growth of seedlings is 13-14 cm. The coefficient of variation for shoot length for most groups of seedlings exceeds 30%. The suburban seedlings have the largest shoot thickness and exceed 0.3 cm. Among urban seedlings, the oak population in the most distant from the city (middle circle), is close to this indicator. The areas of the lowest emission load of pollutants coincide with the forest areas of the city.

At present much attention is paid to the investigation of the indicative features of organisms on the whole and vegetative objects in particular. However, it should be noted that sources of toxic elements distributed unevenly on the territories and having various character and intensity in the form of the enterprises and constructions create rather motley picture of environmental pollution both by structure of pollutants, and by their concentration. Therefore an important scientific problem is the examination not only of changes in conditions of technogenic influence in general, but the research of dependence of intensity of morphological plants parameters change on structure and concentration of chemical pollutants in the environment, and also the assessment of possible consequences of pollutants accumulation in vegetative objects. This was the aim of this work. To perform the work used landscape-geochemical analysis include, extending the definition of the emission factor load, characteristic technogene sources of pollution in the form of industrial plants, evaluation of storage medium (vegetation). Vegetation condition was assessed by determining morphological parameters - the length and width of the leaf blade. The article presents a comparative assessment of the anthropogenic impact level of the largest industrial enterprises on the air state in the city of Gomel. Enterprises of western and southern industrial zone have proved to make the greatest contribution to the urban air pollution. The value of the standard deviation was used to assess the degree of anthropogenic impact of industrial enterprises on morphological parameters of woody plants. This index increased in the western and southern industrial zones in the direction from the enterprises with the large volume of pollutant emissions to the enterprises with the small volume of emissions. This trend is caused by stabilizing selection action due to the environmental stress in the form of emissions of the industrial enterprises in these zones. It is also revealed that in western and southern industrial zones the formation of the leaf blade length and width depends more on the level of anthropogenic impact of the chemical plant, combined heat and power plant, JSC «Centrolit» and JSC «Gomeldrev» compared with other companies, that should be considered when further improvement of environmental activities. The results are generally characterized by scientific novelty of the research and can be used for the purpose of indexing the level of anthropogenic impact on urban areas and further improve the methods of monitoring the state of the urban environment. Next it is planned to evaluate the morphological parameters of the leaf blade of woody plants growing in the area of two large industrial enterprises of the Gomel region – JSC «Mozyr Oil Refinery» (Mozyr), JSC «Belarusian Metallurgical Plant» (Zhlobin) and in city parklands. Then the further testing of the heavy metals content will be carried out in the samples of woody plants, grasses and soil from the territory of the industrial enterprises and parklands of the city of Gomel, Mozyr, and Zhlobin.

In the present work, the analysis of the variability of quantitative and qualitative morphological traits of Japanese Camellia (Camellia japonica L.) varieties used in greenhouses of botanical institutions in Moscow is considered. The paper considers the following varieties: ‘Governor Mouton’, ‘Madame Lebois’, ‘Covina’, ‘Bella Toscana’, ‘Bonomiana’, ‘Alba Simplex’, ‘Lavinia Maggi’, ‘ Silver Waves ’,‘ Doncklaeri ’. To assess the variability, 10 characters were selected, six of which describe the leaf (leaf blade length, leaf blade width, leaf ovality index, leaf blade base shape, leaf blade apex shape, leaf blade shape) and four – flowers (corolla color, flower diameter, degree of terry and aroma). The variability of quantitative characteristics was assessed by determining the confidence intervals method and calculating the coefficients of variation. The variability of qualitative features was assessed by establishing modalities and determining modes. It is noted that, in terms of quantitative and qualitative characteristics, weak variability is observed in most cases. Thus, the studied varieties of Japanese camellia have stable features that characterize the flower and leaf blade. Keywords: CAMELLIA JAPONICA, JAPANESE CAMELLIA, VARIABILITY, VARIETIES

Gelendzhik is the resort town, there aren't a lot of industrial enterprises here. The main pollutant is transport. The work purpose is the assessment of a condition of the artificial landings of a pine located along the Federal highway "Don" and landings, which is nearly the sea coast. Researches were conducted to a standard technique of the General vital state (A. S. Bogolyubov). The assessment of a condition of pines was carried out during 6 years: from 2010 to 2015. For carrying out research we used 6 experimental grounds on the Markotkhsky spine and 2 control grounds within the town. We investigated 24 trees on each platform, middle age of the trees were 30 - 40 years. Results. 1. The condition of trees in the pine forests located in immediate proximity with the Federal highway "Don" (No. 1, 2, 3) is unsatisfactory. As even weak influences of the majority of atmospheric gaseous pollutants (sulphurous gas, nitrogen oxides, etc.) give effect of a necrosis and hloroz of pine needles, the condition of pines is connected with technogenic pollution. So near the Federal highway "Don" the air environment is strongly polluted by exhaust gases. Information of 2012 confirm that negative influence of the route on Markotkh's vegetation decreases at reduction of load of the route. 2. On the sites located above on a slope (No. 4,5,6) thanks to remoteness and the wind mode intensity of influence of pollutants is lower and a condition of pines the quite satisfactory. 3. Trees on the sites located near the sea (No. 7,8) are in a good shape. Small deterioration of a state is noted in very droughty years. Conclusion. Results of six years' research show that the condition of the plantings which are in close proximity with the road worsens. It is explained by increase in intensity of the movement on the road, especially during a resort season. Gelendzhik is the city with a good ecological shape, but the damage to environment is already caused. If not to take measures, we can lose a unique part of the nature in the future, recreate it will be impossible. Measures of reduction of negative impact of exhaust gases were offered. Results of researches are transferred to ecological department of the City administration of Gelendzhik.

Soil, performing a number of important functions is the geomembrane and affects the flow of most processes in the biosphere. Wherein geochemical processes occurring in the soil play an important role in the fate of contaminants as organic matter while controlling their redistribution in the ecosystem between its various components are generally leads to the formation of stable areas of contamination. The soil not only geochemically components accumulates contaminants, but also acts as a natural buffer that controls the transfer of chemical elements and compounds in the atmosphere. Around industrial enterprises formed geochemical anomalies with high content of pollutants, which can reach a radius of 10-50 km, and the impact of large industrial centers can be traced to a distance of 100 km. All known processes of metal accompanied by the formation of large amounts of waste that pollutes air, water and land surface. Mechanical engineering is an important industry of the Orenburg region and is represented by enterprises of the military-industrial complex, agricultural machinery, machine tools, equipment for ferrous and non-ferrous metals, vehicles, electric household appliances. In the machine-building complex of the Orenburg region includes more than 70 large enterprises. The share of engineering products in the volume of industrial production is about 8%. In this case, the natural environment of the city of Orenburg slabozaschischena from most adverse geo-environmental factors. Based on this, we carried out a study on the quality of soil and environmental situation prevailing in the city of Orenburg, in the zone of influence of the enterprise Plant drilling equipment.

We set the goal to study the development of passenger and freight motor-vehicle transport, the effectiveness of which ensures the continuous operation of large and small industrial enterprises, as well as the urban trading network and the services sector. We analyze the problem on the basis of archival sources drawn from the funds of the State Archive of Contemporary History of the Ulyanovsk Region (SACH UR) and the State Archive of the Ulyanovsk Region (SAUR), which are first put into scientific circulation, as well as materials from a monograph and dissertation research by authors from both regional and Russian level. In the course of the work, we reveal the trends in the development of passenger and freight motor-vehicle transport, its problems and achievements. We consider the measures taken by local party bodies to increase the functioning efficiency of motor-vehicle transport during the twelfth Five-year plan, the development trends of urban transport, as well as its problems and achievements. As a result of the study, we conclude that passenger transport is an important link in the urban economy system, without which the ex-istence of the city as a whole would not have been possible, and its development peak occurred precisely in the years under consideration (1986–1990) when intensive construction of industrial facilities and housing was carried out in the city. The intensive development of urban transport was also associated, with the labor of rationalizers who developed new projects of innovative technologies introduction, which made it possible to increase labor efficiency.
