The article examines the application of topological concepts for analysing the structure and assessing the compactness of a regional settlement system. A methodology is proposed that adapts classical topological invariants to evaluate real transport-planning networks using OpenStreetMap data, taking into account physical-geographical and legislative constraints. Instead of abstract node connectivity indices in the settlement system graph, a new operational indicator – the “exit index” – is introduced.

The aim of the work is to assess the contribution of emissions from forest fires to air pollution using the example of the territory of the Pribaikalsky National park. To achieve this goal, calculations of gross emissions were carried out based on forestry data on fires. With the help of the program complex «Ecologist» calculations of concentrations of impurities emitted into the atmosphere during forest fires were carried out. Based on the results of the calculations, maps of the concentrations of pollutants released into the atmosphere from fires were created.
