Geoinformation mapping and analysis of the spatial structure of the vegetation cover of two key areas located in the area of the Vershina Khandy village and the village of Tokma for two time slices: 2013–2014 and 2018–2019 (before and after active forest fires, mainly in 2016 and 2017) was carried out. Mapping was done using the Random Rorest supervised classification method, Landsat 8 space images. As a result, 10 classes of vegetation cover were identified on the territory. It is shown that in the territories in 2013–2014 coniferous (light coniferous – pine-larch, larch-pine, less often dark coniferous – cedar and spruce) forests prevailed, as well as mixed coniferous-deciduous and deciduous forests and swamps. From 2013 to 2019, more than 20% of Tokma and more than 5% of Khanda key area was covered by fires. Mostly coniferous forests, as well as ernik bogs in the Tokma area were burning.</p></abstract><trans-abstract xml:lang="ru"><p>Северные районы Иркутской области в последние десятилетия подвержены пожарам в результате развития нефтегазового комплекса, а также изменяющихся климатических условий. В работе проведено геоинформационное картографирование и анализ пространственной структуры ландшафтного покрова (land cover) двух ключевых участков, расположенных в районе пос. Вершина Ханды и села Токма за два временных среза 2013–2014 гг. и 2018–2019 гг. (до и после активных лесных пожаров преимущественно 2016 и 2017 гг.). Картографирование проводилось с применением инструмента обучаемой классификации Random Forest, космических снимков Landsat 8. В результате на территории было выделено 10 классов ландшафтного покрова. Показано, что на территориях в 2013–2014 гг. преобладали хвойные (светлохвойные – сосново-лиственничные, лиственнично-сосновые, реже темнохвойные – кедровые и еловые) леса, а также хвойно-лиственные и лиственные леса и болота. С 2013 до 2019 г. более 20% Токминского и более 5% Хандинского была пройдена пожарами. Горели преимущественно хвойные леса, а на Токминском участке также ерниковые болота.</p></trans-abstract><kwd-group xml:lang="en"><kwd>vershina Khandy</kwd><kwd>Tokma</kwd><kwd>supervised classification of space images</kwd><kwd>Landsat 8</kwd><kwd>vegetation mapping</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>вершина Ханды</kwd><kwd>Токма</kwd><kwd>ландшафтный покров</kwd><kwd>автоматизированная классификация космических снимков</kwd><kwd>Landsat 8</kwd><kwd>картографирование</kwd><kwd>растительность</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Правительство РФ</institution></institution-wrap><institution-wrap><institution xml:lang="en">Government of the Russian Federation</institution></institution-wrap></funding-source><award-id>АААА-А21-121012190059-5</award-id></award-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Правительство РФ</institution></institution-wrap><institution-wrap><institution xml:lang="en">Government of the Russian Federation</institution></institution-wrap></funding-source><award-id>АААА-А21-121012190056-4</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Alekseeva N.N., Klimanova O.A., Hazieva E.S.
