Introduction. One of the urban planning key tasks is to ensure the personal and social safety and create a high-quality urban environment defined as the ability of the environment to meet human needs. Creating a favorable urban environment is also one of the most important strategic tasks of the state. For that reason, in the nearest future, it is necessary to ensure a cardinal increase in the urban environment comfort, increase the urban environment quality index and reduce the number of settlements with an unfavorable environment. Thus, there is a need to introduce new urban planning system approaches to the assessment of the effectiveness of design solutions in the field of urban green space arrangement. The scope of the research is normative and technical regulation in the field of urban green space arrangement, while its objective is the analysis of the main regulation problems. Materials and methods. The methodological basis of the study is the principles of urban planning based on the calculation of triple balances of the biotechnosphere. By varying the elements of the green space arrangement, it is possible to regulate the level of the biosphere’s regenerative forces, thus balancing the anthropogenic impact on the urban environment. Methods of the research are familiarization with the relevant legal documents in the field of urban green-space arrangement and integrated analysis of urban planning documentation for solving the problems of strategic planning of territorial development. Results. The analysis of the main problems of normative and technical regulation in the field of urban green space arrangement is performed. The functions of gardening in the composition of the urban territorial zones are revealed. The paper shows a gradation of landscaping systems in the urban planning structure at various urban planning levels. A comparative analysis of the landscaping of the territorial zones is given for three major towns of the Central Federal district: Orel, Smolensk, and Tambov. A method to create favorable conditions for life, is proposed for regulating the regenerative forces of the biosphere with the balance ratios of the components of the biotechnosphere balance, including elements of various gardening intensities. Conclusions. Creating a continuous system of green and other open spaces based on the principles of urban planning is currently the main tool for creating a favorable urban environment. Currently, new system approaches are required to assess the effectiveness of design solutions in the field of landscaping and introducing a new integrated indicator of the availability of green spaces.

Abstract. Many urban areas are facing challenges in balancing domestic and industrial water demands while simultaneously maintaining the water supply for green infrastructure. Consequently, quantitative knowledge about ecohydrological partitioning in different types of urban green space is crucial for balancing sustainable water needs in cities during future challenges of increasing urbanization and climate warming. Using isotopic tracers in precipitation and soil water, along with conventional hydrometric measurements in a plot-scale study in Berlin, Germany, we investigated water partitioning under different generic types of urban vegetation (grassland, shrub and trees). This allowed assessment of effects on subsequent evapotranspiration, subsurface flow paths and storage during a prolonged drought period with episodic rainfall. Water losses under forest were slightly higher than grassland over the monitoring in the growing season of 2019. Despite higher soil evaporation losses under urban grassland, higher interception and transpiration likely contributed to slower turnover of soil water and older groundwater recharge under urban trees. Shrub vegetation seemed to be most resilient to prolonged drought periods, with lower evapotranspiration losses. Our results contribute to a better understanding of ecohydrological partitioning under mixed urban vegetation communities and an evidence base for better adaptive management of urban water and irrigation strategies to sustainably meet the water demands of urban green spaces.

Abstract. In cities around the world, urban green spaces provide a range of benefits and ecosystem services. However, recent years have shown how prolonged warm and dry periods can affect urban water resources and lead to water stress in vegetation in urban green spaces, even in temperate regions. Consequently, quantitative knowledge about ecohydrological partitioning in different types of urban green space is crucial for balancing sustainable water needs in cities during future challenges of increasing urbanization and climate warming. Using isotopic tracers in precipitation and soil water, along with conventional hydrometric measurements in a plot-scale study in Berlin, Germany, we investigated water partitioning under different generic types of urban vegetation (grassland, shrub and trees). This allowed for the assessment of urban vegetation effects on evapotranspiration, subsurface flow paths and storage during a prolonged drought period with episodic rainfall. Despite higher soil evaporation losses under urban grassland, higher interception and transpiration likely contributed to slower turnover of soil water and older groundwater recharge under urban trees. Shrub vegetation seemed to be most resilient to prolonged drought periods, with lower evapotranspiration losses. Our results contribute to a better understanding of ecohydrological partitioning under mixed urban vegetation communities and an evidence base for better adaptive management of urban water and irrigation strategies to sustainably meet the water demands of urban green spaces in the future.

Urban green spaces can provide many types of ecosystem services for residents. An imbalance in the pattern of green spaces leads to an inequality of the benefits of such spaces. Given the current situation of environmental problems and the basic geographical conditions of Xi’an City, this study evaluated and mapped four kinds of ecosystem services from the perspective of equity: biodiversity, carbon sequestration, air purification, and climate regulation. Regionalization with dynamically constrained agglomerative clustering and partitioning (REDCAP) was used to obtain the partition groups of ecosystem services. The results indicate that first, the complexity of the urban green space community is low, and the level of biodiversity needs to be improved. The dry deposition flux of particulate matter (PM2.5) decreases from north to south, and green spaces enhance the adsorption of PM2.5. Carbon sequestration in the south and east is higher than that in the north and west, respectively. The average surface temperature in green spaces is lower than that in other urban areas. Second, urban green space resources in the study area are unevenly distributed. Therefore, ecosystem services in different areas are inequitable. Finally, based on the regionalization of integrated ecosystem services, an ecosystem services cluster was developed. This included 913 grid spaces, 12 partitions, and 5 clusters, which can provide a reference for distinct levels of ecosystem services management. This can assist urban managers who can use these indicators of ecosystem service levels for planning and guiding the overall development pattern of green spaces. The benefits would be a maximization of the ecological functions of green spaces, an improvement of the sustainable development of the city, and an improvement of people’s well-being.

Health And Well Being

The quality of life in our cities critically depends on the intelligent planning and shaping of urban living space, in particular urban nature. By providing a wide range of ecosystem services (ES), urban nature essentially contributes to the well-being of city dwellers and plays a major role in avoiding common diseases through its positive impact on physical and mental health. Health is one of the most important factors underlying human welfare and is, thus, vital to sustainable development. The ES of urban green space provide other social-cultural functions alongside public health, for example by fostering environmental justice and citizenship participation. Thus, they should always be considered when searching for solutions to urban problems. The aim of this research was to determine the impact of green areas in three selected cities on the health and well-being of people by self-reporting of green areas’ visitors. To this end, we posed the research question: which types and characteristics of urban green space are most appreciated by city dwellers? Based on our findings, we have drawn up recommendations for practices to promote better living conditions. We have also pinpointed obstacles to and opportunities for leisure time activities as well as ways of supporting the public health of citizens.
