[The municipal planning for the benefit of health].

The article, on the basis of analysis of scientific publications, presents brief overview of principles and technologies of development of cities considering impact on population health. The particular attention is paid to analysis of being built areas and careful use of available resources. The definition of the term "sustainable development of territory" and description of necessary measures for its application in practice are given. The actual trend of "coronavirus" transformation of architectural urban environment is presented, including availability for each family member of one's own space, room, house and flat with terrace, balcony, separate entrances (in case when apartment is located on the first floor), expanded house territory, life outside the city. At that, reduction of social relationships is established. To control effectiveness of city management corresponding indices are presented.

Very high-resolution remote sensing-based mapping of urban residential districts to help combat COVID-19.

Urban residential districts (URDs) are a major element in the formation of cities that are essential for urban planning. Regarding the COVID-19 virus, which remains variable in aerosols for several hours, airborne transmission tends to occur in areas of poor ventilation and high occupant density. Thus, ventilation capacity is an important factor influencing airborne transmission in URDs, which should be evaluated as part of efforts to fight COVID-19 and guide healthy city planning and implementation. Here, we develop and test systematic methods to map URDs in a typical city in northern China and quantify their ventilation capacity using very high-resolution remote sensing images. Four fundamental spatial forms of URD are identified in the research area: the point-group form, parallel form, enclosed form, and hybrid form. Our analyses indicate that the integrated ventilation capacities for well-designed URDs are nearly twice those of poorly designed URDs. Large variations in ventilation capacity are also observed within URDs, with up to 13.42 times difference between the buildings. Therefore, very high-resolution remote sensing data are fundamental for extracting building height and generating precise spatial forms, which can improve the micro-scale URD ventilation planning for the prevention of COVID-19.
