This article provides information on the ecology of lawn communities in the cities of the Urals of the Republic of Bashkortostan (Ufa, Sterlitamak, Salavat, Ishimbay, Meleuz, Birsk, Neftekamsk, Yanaul). On the basis of 195 relevés, the ecological regimes of lawn communities and their species were determined using the ecological scales of Landolt. DCA ordination of the relevés confirmed their floristic differentiation into 4 associations, 2 subassociations, and 5 facies assigned to the alliance Cynosurion cristati of the class Molinio–Arrhenatheretea. The main contribution to the differentiation of communities is made by the thermoclimatic factor, soil moisture and nutrient regimes. The ranges of values of environmental factors of the lawn communities are determined. When conditions deteriorate, there is a succession of lawn communities from subass. typicum of the ass. Leontodono–Poetum pratensis via the subass. cichorietosum intybi of the same association to the ass. Poo pratensis– Plantaginetum majoris. At the same time, species diversity first increases due to the invassion of synanthropic species, and then decreases. Lawns considered to belong to synanthropized vegetation when the number of synanthropic species reaches 56–63 %. Along with traditional herbal mixtures with Poa pratensis, herbal mixtures with Festuca rubra and Lolium perenne are recommended, the combination of which better corresponds to a fairly wide range of environmental conditions of the Urals. Regular maintenance, watering and mowing are also necessary, which extend the life of the lawns.

In this article, on the basis of materials of archive of the State book chamber of the Republic of Bashkortostan, administration of Ufa Federal postal communication service of the Republic of Bashkortostan – branch of FSPA «Mail of Russia», as well as data from the current archives of a number of areas with compact settlement of the Chuvash population the authors carried out the study of national-linguistic needs of the Chuvash in the field of printed products. In two regions – Aurgazinsky and Bizhbulyaksky – with a high proportion of the Chuvash, newspapers in the Chuvash language are published. In other regions, in order to meet their national-language needs, the Chuvash population subscribes to periodicals from the Republic of Chuvashia in the Chuvash language. The range of such periodicals represented a wide range of genres according to the interests. If teachers and educators of Chuvash schools in Bashkortostan mostly subscribed to educational and methodical literature in the Chuvash language, a significant part of subscribers preferred newspapers and magazines about the life and everyday routine of their fellow-countrymen in the Republic of the same name. During the period of perestroika of the Soviet society in October 1989, Bashkortostan started publishing a Republican newspaper in the Chuvash language «Ural Sassi» («Voice of the Urals») with a frequency of once a week, which received a massive demand among the Chuvash population of the Republic. The analysis of subscriptions to periodicals in the Chuvash language in the Republic of Bashkortostan at the present stage shows that the Chuvash population reads less in the language of the mother ethnic group in favor of reading newspapers and magazines in the Russian language.

The main data on the geobotanical database – Database of antropogenic vegetation of Urals and adjacent territories registered in the Global Index of Vegetation-Plot Databases and the European Vegetation Archive are presented. The database includes more than 4,000 complete geobotanical relevés made between 1984 and 2020. The database contains the territories of 3 subjects of the Russian Federation (the Republic of Bashkortostan, Orenburg, Chelyabinsk regions) and 1 - the Republic of Kazakhstan (Aktobe region). For each relevés, a complete list of species with indication of abundance in points on the Braun-Blanquet scale. The main indicators (total cover, average height of the grass, etc.). For most descriptions, GPS coordinates and location are given. The ecological conditions were assessed with use of average values of E. Landolt scale. In the J. Braun-Blanquet classification system, all communities included in the database belong to nine vegetation classes (7 anthropogenic and 2 semi-natural), 75 associations and various types of communities. Geobotanical relevés with the dominance of such aggressive invasive species (Acer negundo, Ambrosia psylostachya, Echinocystis lobata, Elodea canadensis, Solidago canadensis, Heracleum sosnowskyi, Hordeum jubatum, Xanthium albinum etc.) are also included in the database.

This article presents comparative data on the study of several composite multicomponent and monocomponent lawn cenoses based on the analysis of their density and decorative score. To ensure the best stability, projective coating and decorativeness, it is important when choosing components and composing herbal mixtures to take into account their interspecific dynamics of development, pace of development and longevity. Optimum cenoses are obtained by combining species from the rhizome-bush group, slowly growing, yet more long-lived, such as Festuca rubra L., Poa pratensis L. The decorativeness of such cenoses is about 7.5 points, density about 20000 pcs / m2. With age, in complex cenoses, the density of shoots increases, in monotypic ones it decreases.

Data of long-term researches (2015–2018) in southern forest-steppe zone of the Republic of Bashkortostan, is justified theoretically and experimentally the mode of irrigation of potatoes on leached chernozems of unsatisfactory, satisfactory and good ameliorative condition of irrigated lands. For the growing periods of potatoes with different heat and moisture supply, the number of watering, the timing of their implementation, irrigation and irrigation norms are established. On lands with unsatisfactory meliorative state the number of irrigation depending on weather conditions of potato vegetation period varied from 0 to 3 (1.5 on average) with average irrigation norm – 990 m3/ha. With satisfactory meliorative state of lands the number of irrigation on average increased from 0 to 4 (2.3 on average) with irrigation norm – 1305 m3/ha. On lands with good meliorative state the number of irrigation was the highest – from 1 to 5 (3 on average) with average irrigation irrigation norm is 1653 m3/ha. It was noted that in the dry periods of potato vegetation the greatest number of watering was carried out (3–5 watering), and in the wet periods (2017) watering was not carried out except for the area with a good reclamation state, where only one irrigation was carried out by the norm of 550 m3/ha. Water consumption of potato was studied in dynamics as a whole during the growing season and the months of the growing season depending on weather conditions of vegetation period and land reclamation condition of irrigated lands, as well as in the control (without irrigation). The lowest total water consumption was in the area without irrigation and averaged 226.8 mm. In irrigated areas, its values increased to 319-353.4 mm. The average daily water consumption varied from 2.12 to 3.3 mm. The highest rates of potato water consumption were observed in June and July, and the lowest – in May and August. In the total water consumption of potatoes on the site without irrigation, the largest share was occupied by atmospheric precipitation and in addition to them the arrival of moisture from the soil. Irrigation water was used in irrigated areas along with precipitation, the share of which was 30.2–46.1 %.

Introduction. The important factors affecting health and performance of young people are the conditions of education, in particular, a comfortable microclimate in the classrooms of higher educational institutions. Materials and methods. In view of the urgency of this problem, an analysis was made of the microclimate parameters of educational organizations of different profiles (Ufa city, the Republic of Bashkortostan). 294 classrooms were studied in 22 buildings of 4 leading universities in Ufa. A total of 3,822 measurements were taken to determine the parameters of the microclimate. The analysis of ionizing radiation in the aerial environment of classrooms. There was performed determination of radon and its affiliated products content. In order to assess the conditions and lifestyle of students of 4 higher educational institutions of the city of Ufa, we conducted an anonymous survey of 1,820 students of I and IV years of education. Results. The average temperature in the classrooms of all universities studied was 23.9±0.09 C. The average relative humidity in all classrooms was 34.2 ± 0.42%. Analysis of ionizing radiation (radon and its daughter products decay) in the aerial environment of the classrooms and sports halls located in the basement determined that the average annual equivalent equilibrium volumetric activity of the radon daughter products (EROA ± Δ222Rn) ranged from 28 ± 14 to 69 ± 34.5 meter, which meets the requirements established by SanPiN. Conclusion. The hygienic assessment of the microclimate parameters of educational institutions of various profile revealed a number of deviations from the regulated norms. The results indicate the need to control the parameters of the microclimate, both from the administration of universities, and from the professors. According to the results of the study, recommendations were prepared for the management of higher educational institutions in Ufa.
