Geo Аssets Engineering, 2023, vol. 334, no. 6, рр.113-119. In Rus. The relevance. About 50 % of the population of the Jewish Autonomous Region lives on the territory of Birobidzhan and a 10-kilometer zone from its border. In this regard, it is important to analyze the features of the spread of vegetation fires in the vicinity of the city and the intensity of smoke exposure. The main aim: analysis of the influence of vegetation fires on the state of atmospheric air in Birobidzhan. Objects: vegetation fires in a 10-kilometer zone from the border of Birobidzhan. Methods. The work is based on the data about the number of fires in the vicinity of Birobidzhan for 2010–2015 and 2017–2020 according to the Department of Forest Management of the Government of the Jewish Autonomous Region. To display the spread of fires, a vegetation burnability map was made in the study area in the MapInfo Professional 9.0 geoinformation system. The analysis of smoke transport was carried out using wind rose graphs. The basis for the construction of maps reflecting the smoke effect was an upgraded formula for modeling Sutton emissions and a method for calculating concentrations of harmful impurities in the atmospheric air OND-86. The author's algorithm is implemented in the MapBasic programming environment, which is included in the MapInfo Professional 9.0 geoinformation system package. A scale of the intensity of smoke exposure to the atmosphere for the studied area is obtained. Results. The most and least fire-hazardous months for 2010–2015 and 2017–2020 were identified. Territories that are constantly exposed to vegetation fires were marked. In accordance with the graphs of the wind rose, cartograms reflecting the intensity of the smoke effect on the atmosphere of Birobidzhan were made.
