This article analyzes the planning organization of the city of Rostov-on-Don within the framework of implementing the concept of sustainable development and identifies existing spatial and functional imbalances. Dense, mixed-style development, congested transport infrastructure, and uneven distribution of green spaces negatively impact not only the city's environmental status but also the quality of life of the population, necessitating a comprehensive consideration of environmental, spatial, and socioeconomic aspects to optimize urban planning decisions.

Keywords: sustainable development, urban environment, dense urban development, infill development, landscaping and amenity improvement, prospective development of territories

This article concentrates on the issues of radio wave propagation in forest conditions. The issue of representing the forest mass as a heterogeneous structure with a low dielectric constant is considered. Calculation and comparison of radio signal attenuation using several empirical models were carried out. It is shown that empirical models take into account the heterogeneous structure of the forest when moving from free space to the forest.

Keywords: radiowave propagation, wooded area, empirical model, radiowave attenuation, path loss, ground mobile communication, electrodynamic characteristics of a heterogeneous structure
