The goal of the study is to make a comparative analysis of the dynamics of indices of economic indicators and sufficiency indicators used to calculate an urban environment quality index of a Russian municipality. The city of Kirov, Russia, was taken as a sample for the study, which went on from 2012 through 2018. The analysis demonstrated practically no statistically significant correlations in the dynamics of indices of individual subgroups of indicators, as well as in the dynamics of indices of individual indicators, although with a few exceptions. The results of the study confirm the need to improve the methodology of calculating the integral indices of cities and regions. These indices are related to urban ecology, quality of life, and sustainable development issues. The results also demonstrated the inadequacy of such tools for systematic and comprehensive international analysis of today urbanization problems.

AbstractThe aim of this study was to reveal the chemical composition of bottom sediments in karst lakes located in the northern part of Połaniec Basin (eastern part of the Nida Basin, vicinity of Staszów municipality). A field investigation was carried out in 2010 on four lakes: Duży Staw, Donica, Dziki Staw and Łajba. The contents of a very wide range of chemical elements were determined, which is a rarity. On the basis of our research, it was found that the analysed lakes differed considerably between each other in spite of their close location. In general, sediments contained fair amounts of organic substances as well as Fe, Al, Ca and Mg due to the type of source rock and soligenic lake water supply. Increased concentrations of V, Cr and Ni might be explained by the weathering of rock material. In turn, higher contents of Zn, Pb, Cu and Co in the bottom sediments from Duży Staw indicated anthropopression. The measurement results obtained in this study will allow a future comparative analysis with bottom sediments from other lakes.

The article is devoted to the method of calculating the urban environment quality index on the territory of the Russian Federation. The authors reviewed the existing methodology for calculating the urban environment quality index of cities, and made a comparative analysis of statistical data and sample research materials on this issue. As a result, some discrepancies were found in the calculation of the following indicators: “the share of green areas”, “attractiveness of green areas”, “variety of services in green areas”. The article proposes a method for calculating the indicator: “the share of green areas” and a model for adjusting the following indicators: “attractiveness of green areas”, “variety of services in green areas”. Application of this method and adjustment of indicators will not only lead to changes in the calculation of the urban environment quality index for the city of Barnaul and for other cities of the Russian Federation, but will also allow to “qualitatively” evaluate Russian cities by the level of improvement and comfort of living of residents. Thus, Federal authorities will be able to provide targeted assistance to municipalities in areas where there is an urgent need.

The problem of interaction of preschool children with the urban environment is analyzed. The study appears to be of relevance due to its focus on children’s personal agency investigated through their perception of objects and phenomena of the social and physical space of the megalopolis. The study aims to perform a comparative analysis of how groups of children who differ in their modality and orientation of their attitude to the urban environment perceive the city. Presumably, there are differences in the perception of the megalopolis by preschool children. It is also assumed that there is correlation between the attitude of children to the city and the degree of their personal agency properties. The study involved 115 children aged 5.5 to 6.5 years old, living in full families, in two districts of Moscow (58% of them are girls, 42% of them are boys). The experts were teachers of preschool institutions attended by the respondents. Psychodiagnostic tools were used including a semi-structured interview, a drawing test "The City Where I Live", the methodology "Peculiarities of Manifestation of the Preschoolers’ Will" (R.M. Gevorkyan), the scale "autonomy" of the methodology "Typology of Subject Regulation of the Child" (S. V. Khusainova and G. S. Prygin), and a questionnaire. The results of the research demonstrate that children differ in their orientation and modality of attitude to objects and phenomena of the social, natural, objective and spatial environment of the city, and in their attitude to environmental problems of the city and orientation towards their solution. The selectivity and scope of the perception of the urban environment depends on the meaning which children attribute to these objects and phenomena, as well as on personal experience of interacting with them. The importance of the social environment of the city is associated with children’s pronounced independence and self-control; the negative modality of attitude to objects and phenomena of the social environment is associated with reduced self-control of behavior. The increased attention of children to the environmental problems of the city is due to the upbringing by grandparents. The research shows that in conditions of limited interaction with objects and phenomena of the urban environment, children compensate for the lack of experience with fantasies about a fabulous and ideal city. The results of the study can be used to identify priorities in the field of social policy in relation to children at the stage of early socialization, as well as when making decisions on optimizing the urban environment which is friendly to children.

This article analyzes the main problems of urban public spaces, because today public spaces can determine the future of cities. It is noted that parks are multifunctional public spaces in the urban environment, as they are an important element of the citywide system of landscaping and recreation, perform health, cultural, educational, aesthetic and environmental functions. The article notes that the need for easily accessible and well-maintained urban parks remains, however, the state of parks in many cities of Russia remains unsatisfactory, requiring reconstruction. A brief historical background of the Park of Culture and Rest of the Soviet period in Omsk is expounded, the analysis of the existing territory of the Park is presented. It is revealed that the Park, being the largest public space in Omsk, does not meet the requirements of modern urbanism, although it represents a great potential for designing the space for the purpose of recreation of citizens. Performed functional zoning scheme of the territory of the Park in question, where its division into functional areas destined for active recreational users of the Park is presented, considered the interests of senior citizens, people with limited mobility, etc. Reconstruction of Parks of the Soviet period can provide the city with additional recreational opportunities, as well as increase its tourist attractiveness.
