Уровень освещенности под пологом древостоя является стратегическим регулятором процессов, происходящих в лесном биогеоценозе, ценной информацией, необходимой для управления лесами, особенно в условиях изменяющегося климата. Правильное регулирование освещенности признано основным способом контроля за восстановлением и развитием леса. Для этого необходимо формирование базы данных по освещенности под пологом разнообразных насаждений и реакции всех компонентов леса на нее. Недостаточно изучена освещенность под пологом северотаежных и притундровых лесов. Исследования проводили в вегетационный период в сосняках, ельниках и березняках Печорского (Республика Коми), Архангельского и Пинежского (Архангельская область) лесничеств. Освещенность измеряли на высоте 1,3 м около полудня. Отличием светового режима притундровых лесов от северотаежных является высокая проницаемость полога. Относительная освещенность на высоте 1,3 м под пологом различных типов притундровых лесов и при разных видах погоды превышает относительную освещенность в северотаежных лесах в 3,6-5 раз. В результате здесь формируются более высокие уровни освещенности. Большая проницаемость полога в притундровых лесах обусловлена сомкнутостью крон. При схожей с северотаежными лесами относительной полноте древостоя сомкнутость крон ниже практически в 2 раза. Доля пропускаемой под полог солнечной энергии в пасмурную погоду больше, чем в солнечную, на 2–16%. Влияние типа леса на подпологовую освещенность неоднозначно. Помимо вида погоды необходимо учитывать дальность от кромки леса. В притундровых лесах на освещенность влияет доля березы в составе древостоя. </p></abstract><trans-abstract xml:lang="en"><p>The article provides an assessment of the illumination under the canopy of the forests of the Arctic zone of the European North. The level of illumination under the canopy of a stand is a strategic regulator of the processes occurring in the forest biogeocenosis, valuable information necessary for forest management, especially in a changing climate. Proper regulation of illumination is recognized as the main way to control the restoration and development of forests. To do this, it is necessary to create a database on the illumination under the canopy of various plantings and the reaction of all components of the forest to it. The illumination under the canopy of the North taiga and tundra forests has not been sufficiently studied. The research was carried out during the growing season in pine forests, spruce forests and birch forests of Pechora (Komi Republic), Arkhangelsk and Pinezhsky (Arkhangelsk region) forest districts. The illumination was measured at a height of 1.3 m around noon. The difference between the light regime of tundra forests and North taiga forests is the high permeability of the canopy. The relative illumination at an altitude of 1.3 m under the canopy of various types of tundra forests and under different types of weather exceeds the same value in the North taiga forests by 3.6-5 times. As a result, higher levels of illumination are formed here. The high permeability of the canopy in tundra forests is due to the closeness of the crowns. With a relative abundance of trees similar to the Northern taiga forests, the crown closure are almost 2 times lower. The share of solar energy transmitted under the canopy in cloudy weather is 2-16% more than in sunny weather. The influence of the type of forest on the sub-ecological illumination is ambiguous. In addition to the type of weather, it is necessary to take into account the distance from the edge of the forest. In tundra forests, the proportion of birch in the composition of the stand affects the illumination.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>освещенность под пологом леса</kwd><kwd>относительная освещенность</kwd><kwd>притундровые леса</kwd><kwd>северотаежные леса</kwd></kwd-group><kwd-group xml:lang="en"><kwd>illumination under the forest canopy</kwd><kwd>relative illumination</kwd><kwd>forest tundra</kwd><kwd>northern taiga forests</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Работа проведена по результатам исследований, выполненных в рамках государственного задания ФБУ «СевНИИЛХ» на проведение прикладных научных исследований, регистрационный номер темы – 123032700030-9; в рамках государственного задания Федерального исследовательского центра комплексного изучения Арктики имени академика Н.П.
