Ensuring and maintaining the environmental safety of the urban population living in an industrial city in the vicinity of a large city-forming enterprise in conditions of constant emission of industrial dust and gases into the air has always been and is today one of the urgent problems of the architecture of the city of Magnitogorsk. The article examines the historically existing urban planning situation in Magnitogorsk in the conditions of the climate and wind direction of the South Urals, the accounting of which largely contributes to the protective qualities of the air despite the significant emissions of man-made pollution into the atmosphere of the Magnitogorsk Iron and Steel Works (MMK). The original location of industrial buildings and residential areas during the construction of Magnitogorsk was carried out in the 30s of the XX century on the basis of a purely economic approach, bringing housing as close as possible to production, not taking into account wind flows from the construction site and cutting down perennial trees on the slopes of magnetic mountains for the construction of buildings and structures ... After 10 years of MMK operation, the significant role of the South Ural wind in maintaining the ecological situation in the city was proved. Until now, thousands of city residents continue to live in close proximity to MMK, feeling the harmfulness of industrial emissions that pollute the atmosphere. Later, the residential zone of the city began to develop to the south along the right bank, and the industrial zone to the north along the left bank of the river, thus creating further many unfavorable environmental problems that sometimes have to be eliminated.

The formation of the ecological framework of the city determines its viability in general as a modern settlement structure that meets the requirements of sustainable development. In this case, the ecological framework of the city becomes the basis that will be able to form a single ecosystem of the city and establish a format of connections between its various elements. The purpose of the article was to determine the role of the settlement area in the formation of the ecological framework of a large city. This article identifies the role of residential areas in the formation of the ecological framework of the city. The author analyzes the concept of "ecological framework" and its compliance with the peculiarities of the urban structure. It was found that the ecological framework is mainly interpreted as a natural framework. In an urban environment, this leads to certain inconsistencies. The city also has its own spatial framework, which includes a number of properties and characteristics. Therefore, the author proposes to consider the ecological framework of large cities as a system of interaction of natural and urban frameworks. Establishing the right relationship between them will ensure compliance with the level of environmental safety in the city and its sustainable development. It was established that there is no understanding of the concept of ecological framework in the context of urbanization. Most authors consider the ecological framework exclusively as a natural framework of the territory, which is relevant for large areas outside large cities. It is proposed to take into account the peculiarities of the existence and development of the urban organism, which has its own structure, its own spatial framework. It is determined that the urban framework consists of elements of different functions, which are interconnected by a network of communications. All elements create a certain load on the natural structure of the territory (natural framework). It is proposed to consider the ecological framework of a large city as a combination of natural and urban framework. It is their rational combination that will help to improve the environmental situation as a whole and will meet the conditions of sustainable development of the city.

On the territory of the left-bank part of Perm, the urban pedocomplexes (UPC) were distinguished as a combination of soil and technogenic surface formations on the same soil-forming rocks within a certain functional zone. Within the UPC, formed on eluvial-deluvial loams and clays in the zone of multi-storey buildings, the surface horizons of soils and TSF (technogenic surface formations) were studied. A change in the zonal trend of humus formation in reclaimed soils was observed as an increase in the content of organic matter, as well as in a change in the type of humus to the humate side. The conservation of zonal features of humus formation in non-purposefully recultivated urban soils and TSF was noted. It manifests in a low or medium content of organic carbon, the formation of a humate-fulvate type of humus.

The sphere of life of a large city includes forests as a natural resource and areas of its expansion and now they serve to implement modern eco-trends. In the evolution of Lviv we can distinguish several stages of relation to forested areas: 1 - exemption from forests of areas suitable for farming, horticulture and construction; 2 – the early 19th century. - planting of new forests for economic and rehabilitation purposes; 3 - the turn of the 19th and 20th centuries - the development of the recreational function of forests under the influence of hygienists, especially at water sources; 4 - the end of the 19th century and before 1939 - the development of the city of Lviv with new streets and compact plots according to the urban concepts of "villa in the park" and "garden city", which are wedged into the forest park areas; 5 - the second half of the 20th century. The rapid territorial development of industrial Lviv causes the emergence of large residential areas on the outskirts of the city. According to strict regulatory requirements for providing residents with green areas, part of the suburban forests were allocated for the establishment of local parks. A trade union recreation centers are developing around the city; 6 - 1980s - under the influence of the concept of a polarized landscape in conditions of state ownership of land and its resources, in suburban forests and in the city, separate plots with unique characteristics are distinguished, on the basis of which objects of nature reserve fund are created; 7 - from the 1990s and until now - the spreading of the city and the defragmentation of forests are observed. At the same time, the creation of new nature reserve facilities in Lviv and in the suburban area were performed as well as the formation of new reserves and their inclusion into European ecological networks. At the same time, the process of permanent alienation of forest areas in favor of the spread of development is intensifying. The most vulnerable are the territories of Bryukhovychi and Vynnyky forest parks, which are fully included in the united territorial community of Lviv approved in 2020.

This article examines the urban public and business subcenters as secondary elements of the city system, the closest in properties to its main center. The criteria defining the public business subcenters are highlighted. The current trends in the formation of social and business subcenters in large cities and megalopolises are considered. Analysis of world experience is produced. Foreign concepts of spatial development are analyzed on the example of several existing urban subcenters. Various available cartographic materials and literature sources have been studied. They cover the development of urban business centers and various aspects of urban development. The methods of spatial formation of the planning structure of urban public business subcenters are highlighted: the cluster and channel. The development stages of urban subcenters from the territory of concentration of small trade and residential establishments to large-scale multifunctional urban planning formations are presented. The prospects for the development of business subcenters in major cities of the Russian Federation are analyzed and trends are identified: social and business polycentrism, disposition of administrative and business centers on the outskirts of cities and the formation of self-organizing business subcenters, mainly based on shopping and entertainment centers in residential areas. Prospects for development of urban subcenter in a large city are considered on the example of the city of Belgorod. Conclusions are drawn on the need to develop new models of urban public business subcenters taking into consideration the modern planning specifics of large cities and megalopolises of the Russian Federation. Models of urban public business subcenters must meet the requirements of polyfunctionality, to have high architectural and town planning qualities, to take into account the needs of population in the design area and to ensure the sustainable development of the urban periphery.

The article is devoted to the problem of ensuring environmental safety in the territories of large cities, primarily, to reducing atmospheric air pollution. The aim of the work was to build a comprehensive classification scheme of sources of pollutant emissions into the air basin of the territories of large cities, taking into account the climatic and physicalgeographical conditions of the considered urban areas. In the process of research, we solved the problem of identifying the basic principles of classification of air pollution sources based on the analysis of known methodological approaches with the subsequent improvement of calculation methods to justify the spatial distribution of residential areas, industrial areas, motorways, recreational areas, effective sanitary protective zones taking into account aerodynamics to remove polluted air outside the city territory. A generalized classification of sources of pollutant emissions into the environment is proposed, while the sources of air pollution in urban areas are classified according to the following main criteria: by origin, by aerodynamic parameters and by the nature of the direction of the emission plume, by spatial position and possible mobility, in terms of size in plan, in height of the spread of the emission plume, taking into account the height of the mouth of the source of the emission of pollutants above the level of the earth’s surface, in temperature of air-gas mixture, according to the mode of action.

Urban Fauna

In this work, the topographic features of the spatial pattern of biodiversity of the urban fauna in general in the city are revealed: the number of urban fauna species has a maximum in the southern part of the city and a minimum in the western part. The mammal fauna as a component of urban fauna in general exhibits greater plasticity and adaptability in relation to humans compared to other groups of biota, for example, the insect fauna and avifauna. The urban mammal fauna in Ulyanovsk has historically formed due to the penetration of representatives of various faunal complexes that inhabit the region into the city area and its vicinities: (1) floodplain species associated with the river Sviyaga and its tributaries, 36.17%; (2) forest species living in pine-deciduous, deciduous-pine, and taiga forests, 46.81%; (3) upland-steppe species associated with Cretaceous landscapes of the right bank, 6.38%; (4) steppe species, including mammals of the left bank, common for the native feather grass–fescue steppes, 6.38%. Some animal species have remained in the city and in the region due to their spread by humans—introduced species and species kept in fur farms (10.64%). Synanthropic species are associated with human settlements (4.26%). The occurrence of species in different zones of the city (right bank and left bank) and habitats with an increase in the level of urbanization and a decrease in species diversity (1–5) are as follows: (1) green zones—parks and squares with woody vegetation, 31 species; (2) floodplain of the river Sviyaga within the city, 24 species; (3) summer cottages within the city, 15 species; (4) private sector with one-storey buildings, 5 species; (5) multi-storey buildings, 4 species. In general, in an urban environment, mammal species that coexist with humans make up 66.19 % of the total number of mammal species in the region. At the same time, the number of rare mammal species listed in the regional Red Book is 12.68%. Thus, when conservation measures for the protection of animal habitats within the urban environment are observed, most species are able to maintain stable populations.

The article considers the most optimal approaches to the development and development of transit areas, aff ecting the actual problems of a modern large city: the development of citywide functions based on promising transportation hubs, the resolution of the confl ict of transit passenger directions and the urban social environment. As one of the main mechanisms to achieve safety in the operation of urban transport systems, the principles of architectural and spatial formation of transport infrastructure are put forward, including the principle of biopositivity in the structure of transport territories, the principle of environmental safety of transport, the principle of accessibility of transport, the principle of constructive safety, the principle of multilevel linear and central transport elements, the principle of universality of road maintenance. Examples are given from the practice of using these or other methods of forming transport nodes and linear sections in order to improve traffi c safety. The possibilities of the development of safe transport structures in the strategic forecasts of the development of the city are shown.

Tangut is the dead Tibeto-Burman language of the Buddhist empire of Xīxià, which was destroyed in 1227 by the Golden Horde of the Mongol warlord Temuüjin, more commonly known as Genghis Khan (c. 1162–1227). The Tangut empire was established in 1032 and comprised the modern Chinese provinces of Gānsù, Shānxī and Níngxià, extending from the Yellow River in the east to Kökö Nōr (Chinese: Qīnghăi Hù) in the west. The northern frontier of the Xīxià empire skirted the city of Qumul (Chinese: Hāmì), the river Edzin Gol (Chinese: Ruò Shuĭ), the Hèlán hills and the Yellow River. In the south, the empire extended down into the present-day province of Sichuān. The Xīxià capital was situated in what is now the city of Yinchuān (formerly Níngxiàfŭ) on the left bank of the Yellow River.

For over a century scholars have been attempting to locate the area and, if possible, the actual site of the capital of the Mali empire in its period of greatness. Since the 1920S attention has been focused on an area near the Sankararni river, a tributary entering the Niger from the south, upstream from Bamako. Over recent years a Polish-Guinean archaeological expedition has been digging a site there, but with inconclusive results so far.A close reading of the few descriptions we have of the capital of Mali, and in particular of the route taken by Ibn Battūta, who visited the capital in 1352, suggests that the city lay on the left bank of the river Niger somewhere between Segu and Bamako. This is in fact a ‘logical] site for the capital of an empire whose tributaries lay mainly in the savannah and Sahel belts, and in whose armies cavalry played a significant role. For this reason, and a number of others, the recent hypothesis of Claude Meillassoux, suggesting a location for the capital south of the R. Falémé (and perhaps also of the R. Gambia), seems doubtful. The proper name for the capital is also discussed.

<p>Some areas in the city of Bandung is an area that dilitasi by the flow of the river, to prevent the introduction of garbage into the river basin is necessary to note the waste management systems in residential areas along the river. Cidurian river has a length of 24.86 Km along the river flow. Consists of the city of Bandung and Bandung regency. Administrative regions Cidurian River past eight (8) districts, from the region in the District Kiaracondong precisely Village Babakan Babakan Sari and Surabaya populous and the most densely populated. Thus, there should be community-based waste management in the form of a reduction in resources to prevent potential entry of waste into the river basin. Planning waste reduction will be divided into two, namely the reduction of inorganic waste with waste bank then the reduction of organic waste with absorption holes biopori, and bio reactor mini determination of the reduction is determined by the results of the analysis of the sampling covers the composition and garbage, then the result of the measurement characteristics test and analysis results questionnaire.</p>
