Приводятся данные об образовании и формировании ветровально-почвенных комплексов в зависимости от лесорастительных условий, исходного типа лесных почв, степени воздействия экзогенных разрушительных факторов. As a result of influence of a wind on forest biogeocenosis the phenomenon windfall is observed. It is uprooting of trees together with their root system and soil plate. On a place of the turned out roots will be formed treethrow pit. The thrown out root system with soil plate after rotting of roots will form mound. Fallen a trunk and a crown of a tree also affect vegetation and ground under flat forest. The decomposition of fallen deadwood will be formed of a specific microrelief. Morphologically selected infringements forest biogeocenosis are considered as a soil-windfall complex with characteristic microecotopes in its structure.
